有关描述当前互联网标准管理框架的文件的详细概述，请参阅RFC 3410[RFC3410]第7节。
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB对象通常通过简单网络管理协议（SNMP）进行访问。MIB中的对象是使用管理信息结构（SMI）中定义的机制定义的。本备忘录规定了符合SMIv2的MIB模块，如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。

This document is a companion to the documents that define Managed Objects for the DS0 [RFC2494], DS3/E3 [RFC3896], and Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) [RFC3592] Interface Types.
本文档是定义DS0[RFC2494]、DS3/E3[RFC3896]和同步光网络/同步数字体系（SONET/SDH）[RFC3592]接口类型的托管对象的文档的补充。
These objects are used when the particular media being used to realize an interface is a DS1/E1/DS2/E2 interface. At present, this applies to these values of the ifType variable in the Internet-standard MIB:
当用于实现接口的特定介质是DS1/E1/DS2/E2接口时，使用这些对象。目前，这适用于Internet标准MIB中ifType变量的这些值：
ds1 (18)
ds1（18）
The definitions contained herein are based on the AT&T T-1 Superframe (a.k.a., D4) [ANSI-T1.107] and Extended Superframe (ESF) formats [AT&T-UM-305] [AT&T-TR-54016], the latter of which conforms to ANSI specification [ANSI-T1.403], and the CCITT Recommendations [CCITT-G.703] [ITU-T-G.704], referred to as E1 for the rest of this memo.
本文包含的定义基于AT&T T-1超帧（又称D4）[ANSI-T1.107]和扩展超帧（ESF）格式[AT&T-UM-305][AT&T-TR-54016]，后者符合ANSI规范[ANSI-T1.403]，以及CCITT建议[CCITT-G.703][ITU-T-G.704]，本备忘录其余部分称为E1。
The various DS1 and E1 line disciplines are similar enough that separate MIBs are unwarranted, although there are some differences. For example, Loss of Frame is defined more rigorously in the ESF specification than in the D4 specification, but it is defined in both. Therefore, interface types e1(19) and g703at2mb(67) have been obsoleted.
各种DS1和E1线路规程非常相似，因此没有必要使用单独的MIB，尽管存在一些差异。例如，与D4规范相比，ESF规范对帧丢失的定义更为严格，但两者都有定义。因此，接口类型e1（19）和g703at2mb（67）已被淘汰。
Where it is necessary to distinguish between the flavors of E1 with and without CRC, E1-CRC denotes the "with CRC" form (G.704 Table 4b) and E1-noCRC denotes the "without CRC" form (G.704 Table 4a).
如果有必要区分有CRC和无CRC的E1，E1-CRC表示“有CRC”形式（G.704表4b），E1 noCRC表示“无CRC”形式（G.704表4a）。
Only the ifGeneralInformationGroup needs to be supported.
只需要支持IFGeneralInformation组。

The object dsx1IfIndex has been deprecated. This object previously allowed a very special proxy situation to exist for Routers and CSUs. This section now describes how to use ifStackTable to represent this relationship.
对象dsx1IfIndex已被弃用。该对象以前允许路由器和CSU存在非常特殊的代理情况。本节现在介绍如何使用ifStackTable表示此关系。
The paragraphs discussing dsx1IfIndex and dsx1LineIndex have been preserved in Appendix A for informational purposes.
讨论DSX1iIndex和dsx1LineIndex的段落已保存在附录A中，以供参考。
The ifStackTable is used in the proxy case to represent the association between pairs of interfaces, e.g., this T1 is attached to that T1. This use is consistent with the use of the ifStackTable to show the association between various sub-layers of an interface. In both cases entire PDUs are exchanged between the interface pairs - in the case of a T1, entire T1 frames are exchanged; in the case of PPP and HDLC, entire HDLC frames are exchanged. This usage is not meant to suggest the use of the ifStackTable to represent Time Division Multiplexing (TDM) connections in general.
ifStackTable在代理情况下用于表示接口对之间的关联，例如，此T1连接到该T1。这种用法与使用ifStackTable来显示接口的各个子层之间的关联是一致的。在这两种情况下，在接口对之间交换整个PDU——在T1的情况下，交换整个T1帧；在PPP和HDLC的情况下，交换整个HDLC帧。这种用法并不意味着建议使用ifStackTable来表示一般的时分多路复用（TDM）连接。
External&Internal interface scenario: the SNMP Agent resides on a host external from the device supporting DS1 interfaces (e.g., a router). The Agent represents both the host and the DS1 device.
外部和内部接口方案：SNMP代理驻留在支持DS1接口的设备（例如路由器）外部的主机上。代理表示主机和DS1设备。
Example:
例子：
A shelf full of CSUs connected to a Router. An SNMP Agent residing on the router proxies for itself and the CSU. The router has also an Ethernet interface:
装满连接到路由器的CSU的架子。驻留在路由器上的SNMP代理为其自身和CSU代理。路由器还具有以太网接口：

The ifStackTable is then used to show the relationships between the various DS1 interfaces.
然后使用ifStackTable显示各种DS1接口之间的关系。

If the CSU shelf is managed by itself by a local SNMP Agent, the situation would be identical, except the Ethernet and the 4 router interfaces are deleted. Interfaces would also be numbered from 1 to 8.

An example is given of how DS1/E1 interfaces are stacked on DS2/E2 interfaces. It is not necessary nor is it always desirable to represent DS2 interfaces. If this is required, the following stacking should be used. All ifTypes are ds1. The DS2 is determined by examining ifSpeed or dsx1LineType.
给出了DS1/E1接口如何堆叠在DS2/E2接口上的示例。表示DS2接口不是必需的，也并非总是可取的。如果需要，应使用以下堆叠。所有IFTYPE都是ds1。DS2通过检查ifSpeed或dsx1LineType确定。

An example is given here to explain the channelization objects in the DS3, DS1, and DS0 MIBs to help the implementor use the objects correctly. Treatment of E3 and E1 would be similar, with the number of DS0s being different depending on the framing of the E1.
这里给出一个示例来解释DS3、DS1和DS0 MIB中的通道化对象，以帮助实现者正确使用这些对象。E3和E1的处理类似，DS0的数量根据E1的帧而不同。
Assume that a DS3 (with ifIndex 1) is Channelized into DS1s (without DS2s). The object dsx3Channelization is set to enabledDs1. There will be 28 DS1s in the ifTable. Assume the entries in the ifTable for the DS1s are created in channel order and the ifIndex values are 2 through 29. In the DS1 MIB, there will be an entry in the dsx1ChanMappingTable for each ds1. The entries will be as follows:
假设一个DS3（带ifIndex 1）被信道化为DS1（不带DS2）。对象dsx3Channelization设置为enabledDs1。ifTable中将有28个DS1。假设DS1的ifTable中的条目是按通道顺序创建的，ifIndex值为2到29。在DS1 MIB中，每个DS1在dsx1ChanMappingTable中都有一个条目。参赛作品如下：
dsx1ChanMappingTable Entries
dsx1ChanMappingTable条目
ifIndex dsx1Ds1ChannelNumber dsx1ChanMappedIfIndex
1 1 2
1 2 3
......
1 28 29
ifIndex dsx1Ds1ChannelNumber dsx1ChanMappedIfIndex
1 1 2
1 2 3
......
1 28 29
In addition, the DS1s are channelized into DS0s. The object dsx1Channelization is set to enabledDS0 for each DS1. When this object is set to this value, 24 DS0s are created by the agent. There will be 24 DS0s in the ifTable for each DS1. If the dsx1Channelization is set to disabled, the 24 DS0s are destroyed. Assume the entries in the ifTable are created in channel order and the ifIndex values for the DS0s in the first DS1 are 30 through 53. In the DS0 MIB, there will be an entry in the dsx0ChanMappingTable for each DS0. The entries will be as follows:
此外，DS1被信道化为DS0。对象dsx1Channelization设置为每个DS1启用DDS0。将此对象设置为该值时，代理将创建24个DS0。每个DS1的ifTable中将有24个DS0。如果dsx1Channelization设置为disabled（禁用），则会销毁24个DS0。假设ifTable中的条目是按通道顺序创建的，并且第一个DS1中DS0的ifIndex值为30到53。在DS0 MIB中，每个DS0的dsx0ChanMappingTable中将有一个条目。参赛作品如下：

An example is given here to explain the channelization objects in the DS3 and DS1 MIBs to help the implementor use the objects correctly.
这里给出一个示例来解释DS3和DS1 MIB中的通道化对象，以帮助实现者正确使用这些对象。
Assume that a DS3 (with ifIndex 1) is Channelized into DS2s. The object dsx3Channelization [RFC3896] is set to enabledDs2. There will be 7 DS2s (ifType of DS1) in the ifTable. Assume the entries in the ifTable for the DS2s are created in channel order and the ifIndex values are 2 through 8. In the DS1 MIB, there will be an entry in the dsx1ChanMappingTable for each DS2. The entries will be as follows:

In addition, the DS2s are channelized into DS1s. The object dsx1Channelization is set to enabledDS1 for each DS2. There will be 4 DS1s in the ifTable for each DS2. Assume the entries in the ifTable are created in channel order and the ifIndex values for the DS1s in the first DS2 are 9 through 12, then 13 through 16 for the second DS2, and so on.

This section discusses the behaviour of objects related to loopbacks.
本节讨论与环回相关的对象的行为。
The object dsx1LoopbackConfig represents the desired state of loopbacks on this interface. Using this object a Manager can request:
对象dsx1LoopbackConfig表示此接口上所需的环回状态。使用此对象，经理可以请求：
LineLoopback PayloadLoopback (if ESF framing) InwardLoopback DualLoopback (Line + Inward) NoLoopback
LineLoopback PayloadLoopback（如果ESF成帧）向内Loopback DualLoopback（线路+向内）NoLoopback
The remote end can also request loopbacks either through the FDL channel if ESF or inband if D4. The loopbacks that can be requested this way are:
远程端还可以通过FDL信道（如果是ESF）或带内信道（如果是D4）请求环回。可以通过这种方式请求的环回包括：
LineLoopback PayloadLoopback (if ESF framing) NoLoopback
LineLoopback PayloadLoopback（如果ESF成帧）NoLoopback
To model the current state of loopbacks on a DS1 interface, the object dsx1LoopbackStatus defines which loopback is currently applied to an interface. This objects, which is a bitmap, will have bits turned on which reflect the currently active loopbacks on the interface as well as the source of those loopbacks.
要对DS1接口上环回的当前状态建模，对象dsx1LoopbackStatus定义当前应用于接口的环回。此对象是位图，将启用位，以反映接口上当前活动的环回以及这些环回的源。
The following restrictions/rules apply to loopbacks:
以下限制/规则适用于环回：
The far end cannot undo loopbacks set by a manager.
远端无法撤消管理器设置的环回。
A manager can undo loopbacks set by the far end.
管理器可以撤消远端设置的环回。
Both a line loopback and an inward loopback can be set at the same time. Only these two loopbacks can co-exist and either one may be set by the manager or the far end. A LineLoopback request from the far end is incremental to an existing Inward loopback established by a manager. When a NoLoopback is received from the far end in this case, the InwardLoopback remains in place.
可以同时设置线路环回和向内环回。只有这两个环回可以共存，其中一个可以由管理器或远端设置。来自远端的LineLoopback请求是由管理器建立的现有内部环回的增量。在这种情况下，当从远端接收到NoLoopback时，向内的LOOPBACK保持在原位。
There are numerous things that could be included in a MIB for DS1 signals: the management of multiplexors, CSUs, DSUs, and the like. The intent of this document is to facilitate the common management of all devices with DS1, E1, DS2, or E3 interfaces. As such, a design
DS1信号的MIB中可以包括许多内容：多路复用器、CSU、DSU等的管理。本文档的目的是促进使用DS1、E1、DS2或E3接口的所有设备的通用管理。因此，设计
decision was made up front to very closely align the MIB with the set of objects that can generally be read from these types devices that are currently deployed.
事先决定将MIB与通常可以从当前部署的这些类型的设备读取的对象集非常紧密地对齐。
J2 interfaces are not supported by this MIB.
此MIB不支持J2接口。
The terminology used in this document to describe error conditions on a DS1 interface as monitored by a DS1 device are based on the late but not final document of what became the ANSI T1.231 standard [ANSI-T1.231]. If the definition in this document does not match the definition in the ANSI T1.231 document, the implementer should follow the definition described in this document.
本文件中用于描述由DS1设备监控的DS1接口上的错误条件的术语基于后来成为ANSI T1.231标准[ANSI-T1.231]的最新但非最终文件。如果本文件中的定义与ANSI T1.231文件中的定义不匹配，则实施者应遵循本文件中描述的定义。
Bipolar Violation (BPV) Error Event A BPV error event for an AMI-coded signal is the occurrence of a pulse of the same polarity as the previous pulse (See T1.231 Section 6.1.1.1.1). A BPV error event for a B8ZS- or HDB3-coded signal is the occurrence of a pulse of the same polarity as the previous pulse without being a part of the zero substitution code.
双极性违规（BPV）错误事件AMI编码信号的BPV错误事件是出现与前一个脉冲极性相同的脉冲（见T1.231第6.1.1.1节）。B8ZS或HDB3编码信号的BPV错误事件是出现与前一个脉冲极性相同的脉冲，而不是零替换码的一部分。
Excessive Zeroes (EXZ) Error Event An Excessive Zeroes error event for an AMI-coded signal is the occurrence of more than fifteen contiguous zeroes (See T1.231 Section 6.1.1.1.2). For a B8ZS coded signal, the defect occurs when more than seven contiguous zeroes are detected.
过零（EXZ）错误事件AMI编码信号的过零错误事件是指出现超过十五个连续零（见T1.231第6.1.1.2节）。对于B8ZS编码信号，当检测到超过七个连续零时，会出现缺陷。
Line Coding Violation (LCV) Error Event A Line Coding Violation (LCV) is the occurrence of either a Bipolar Violation (BPV) or Excessive Zeroes (EXZ) Error Event. (Also known as CV-L; See T1.231 Section 6.5.1.1.)
线路编码违规（LCV）错误事件线路编码违规（LCV）是发生双极违规（BPV）或过零（EXZ）错误事件。（也称为CV-L；见T1.231第6.5.1.1节。）
Path Coding Violation (PCV) Error Event A Path Coding Violation error event is a frame synchronization bit error in the D4 and E1-noCRC formats, or a CRC or frame synch. bit error in the ESF and E1-CRC formats. (Also known as CV-P; See T1.231 Section 6.5.2.1.)
路径编码冲突（PCV）错误事件路径编码冲突错误事件是D4和E1 noCRC格式的帧同步位错误，或CRC或帧同步。ESF和E1-CRC格式中的位错误。（也称为CV-P；见T1.231第6.5.2.1节。）
Controlled Slip (CS) Error Event A Controlled Slip is the replication or deletion of the payload bits of a DS1 frame (See T1.231 Section 6.1.1.2.3). A Controlled Slip may be performed when there is a difference
受控滑动（CS）错误事件受控滑动是指复制或删除DS1帧的有效负载位（见T1.231第6.1.1.2.3节）。当存在差异时，可执行受控滑动
between the timing of a synchronous receiving terminal and the received signal. A Controlled Slip does not cause an Out of Frame defect.
在同步接收终端的定时和接收信号之间。受控滑动不会导致机架外缺陷。
Out Of Frame (OOF) Defect An OOF defect is the occurrence of a particular density of Framing Error events (See T1.231 Section 6.1.2.2.1).
帧外（OOF）缺陷OOF缺陷是特定密度的帧错误事件的发生（见T1.231第6.1.2.2.1节）。
For DS1 links, an Out of Frame defect is declared when the receiver detects two or more framing errors within a 3 msec period for ESF signals and 0.75 msec for D4 signals, or two or more errors out of five or fewer consecutive framing-bits.
对于DS1链路，当接收机在ESF信号的3毫秒周期内检测到两个或多个帧错误，D4信号的0.75毫秒周期内检测到两个或多个帧错误，或者在五个或更少的连续帧位中检测到两个或多个错误时，将宣布帧外缺陷。
For E1 links, an Out Of Frame defect is declared when three consecutive frame alignment signals have been received with an error (see G.706 Section 4.1 [CCITT-G.706]).
对于E1链路，当接收到三个连续的帧对准信号且出现错误时，宣布存在帧外缺陷（参见G.706第4.1节[CCITT-G.706]）。
For DS2 links, an Out of Frame defect is declared when 7 or more consecutive errored framing patterns (4 multiframe) are received. The OOF is cleared when 3 or more consecutive correct framing patterns are received.
对于DS2链路，当接收到7个或更多连续的错误帧模式（4个多帧）时，会声明帧外缺陷。当接收到3个或更多连续的正确帧模式时，OOF被清除。
Once an Out Of Frame Defect is declared, the framer starts searching for a correct framing pattern. The Out of Frame defect ends when the signal is in frame.
一旦声明了帧外缺陷，成帧者就开始搜索正确的成帧模式。当信号在帧内时，帧外缺陷结束。
In-frame occurs when there are fewer than two frame bit errors within 3 msec period for ESF signals and 0.75 msec for D4 signals.
当ESF信号的3毫秒周期内和D4信号的0.75毫秒周期内出现少于两个帧位错误时，会发生帧内错误。
For E1 links, in-frame occurs when a) in frame N the frame alignment signal is correct and b) in frame N+1 the frame alignment signal is absent (i.e., bit 2 in TS0 is a one) and c) in frame N+2 the frame alignment signal is present and correct. (See G.704 Section 4.1)
对于E1链路，当a）在帧N中帧对齐信号正确，b）在帧N+1中帧对齐信号不存在（即，TS0中的位2为1）和c）在帧N+2中帧对齐信号存在且正确时，帧内发生。（见G.704第4.1节）
Alarm Indication Signal (AIS) Defect For D4 and ESF links, the 'all ones' condition is detected at a DS1 line interface upon observing an unframed signal with a one's density of at least 99.9% present for a time equal to or greater than T, where 3 ms <= T <= 75 ms. The AIS is terminated upon observing a signal not meeting the one's density or the unframed signal criteria for a period equal to or greater than T (See G.775, Section 5.4).
对于D4和ESF链路的报警指示信号（AIS）缺陷，当观察到一个密度至少为99.9%且持续时间等于或大于T的非帧信号时，在DS1线路接口处检测到“所有”状态，式中，3ms<=T<=75ms。当观察到一个不符合其密度或无帧信号标准的信号的时间等于或大于T时，AIS终止（见G.775，第5.4节）。
For E1 links, the 'all-ones' condition is detected at the line interface as a string of 512 bits containing fewer than three zero bits (see O.162 [CCITT-O.162] Section 3.3.2).
对于E1链路，“所有1”状态在线路接口处被检测为包含少于三个零位的512位字符串（见O.162[CCITT-O.162]第3.3.2节）。
For DS2 links, the DS2 AIS shall be sent from the NT1 to the user to indicate a loss of the 6,312 kbps frame capability on the network side. The DS2 AIS is defined as a bit array of 6,312 kbps in which all binary bits are set to '1'.
对于DS2链路，应将DS2 AIS从NT1发送给用户，以指示网络侧6312 kbps帧能力的损失。DS2 AIS定义为6312 kbps的位阵列，其中所有二进制位都设置为“1”。
The DS2 AIS detection and removal shall be implemented according to ITU-T Draft Recommendation G.775 [ITU-T-G.775] Section 5.5: - a DS2 AIS defect is detected when the incoming signal has two (2) or less ZEROs in a sequence of 3156 bits (0.5 ms). - a DS2 AIS defect is cleared when the incoming signal has three (3) or more ZEROs in a sequence of 3156 bits (0.5 ms).
DS2 AIS检测和移除应根据ITU-T草案建议G.775[ITU-T-G.775]第5.5节的规定执行：-当输入信号在3156位（0.5毫秒）的序列中具有两（2）个或更少的零时，检测到DS2 AIS缺陷当输入信号在3156位（0.5毫秒）的序列中有三（3）个或更多的零时，DS2 AIS缺陷被清除。
All performance parameters are accumulated in fifteen minute intervals and up to 96 intervals (24 hours worth) are kept by an agent. Fewer than 96 intervals of data will be available if the agent has been restarted within the last 24 hours. In addition, there is a rolling 24-hour total of each performance parameter. Performance parameters continue to be collected when the interface is down.
所有性能参数以15分钟的间隔累积，代理最多可保留96个间隔（24小时）。如果代理在过去24小时内重新启动，则可用的数据间隔将少于96个。此外，每个性能参数都有一个24小时滚动总计。当接口关闭时，将继续收集性能参数。
There is no requirement for an agent to ensure fixed relationship between the start of a fifteen minute interval and any wall clock; however some agents may align the fifteen minute intervals with quarter hours.
不要求代理人确保15分钟间隔的开始和任何挂钟之间的固定关系；但是，一些代理可能会将15分钟的间隔与四分之一小时的间隔对齐。
Performance parameters are of types PerfCurrentCount, PerfIntervalCount and PerfTotalCount. These textual conventions are all Gauge32, and they are used because it is possible for these objects to decrease. Objects may decrease when Unavailable Seconds occurs across a fifteen minutes interval boundary. See Unavailable Seconds discussion later in this section.
性能参数的类型为PerfCurrentCount、PerfIntervalCount和PerfTotalCount。这些文本约定都是Gauge32，之所以使用它们，是因为这些对象可能会减少。当跨越15分钟间隔边界出现不可用秒时，对象可能会减少。请参阅本节后面的讨论。

ESF和E1-CRC链路的错误秒错误秒是指出现一个或多个路径代码冲突、一个或多个帧外缺陷、一个或多个受控滑动事件或检测到AIS缺陷的秒。（参见T1.231第6.5.2.2节和G.826[ITU-T-G.826]第B.1节）。
For D4 and E1-noCRC links, the presence of Bipolar Violations also triggers an Errored Second.
对于D4和E1 noCRC链路，双极性违规的存在也会触发错误秒。
This is not incremented during an Unavailable Second.
在不可用的一秒钟内，该值不会增加。
Bursty Errored Seconds (BES) A Bursty Errored Second (also known as Errored Second type B in T1.231 Section 6.5.2.4) is a second with fewer than 320 and more than 1 Path Coding Violation error events, no Severely Errored Frame defects and no detected incoming AIS defects. Controlled slips are not included in this parameter.
突发性错误秒（BES）突发性错误秒（在T1.231第6.5.2.4节中也称为B类错误秒）是指路径编码违规错误事件少于320次且多于1次、无严重错误帧缺陷和未检测到传入AIS缺陷的秒。受控卡瓦不包括在此参数中。
This is not incremented during an Unavailable Second. It applies to ESF signals only.
在不可用的一秒钟内，该值不会增加。它仅适用于ESF信号。
Severely Errored Seconds (SES) A Severely Errored Second for ESF signals is a second with 320 or more Path Code Violation Error Events OR one or more Out of Frame defects OR a detected AIS defect (See T1.231 Section 6.5.2.5).
严重错误秒（SES）ESF信号的严重错误秒是指出现320个或更多路径代码冲突错误事件或一个或多个帧外缺陷或检测到AIS缺陷的秒（见T1.231第6.5.2.5节）。
For E1-CRC signals, a Severely Errored Second is a second with 832 or more Path Code Violation error events OR one or more Out of Frame defects.

Severely Errored Framing Second (SEFS) An Severely Errored Framing Second is a second with one or more Out of Frame defects OR a detected AIS defect. (Also known as SAS-P (SEF/AIS second); See T1.231 Section 6.5.2.6.)
严重错误帧秒（SEFS）严重错误帧秒是指出现一个或多个帧外缺陷或检测到AIS缺陷的秒。（也称为SAS-P（SEF/AIS秒）；见T1.231第6.5.2.6节。）
Degraded Minutes A Degraded Minute is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3 (see G.821 [CCITT-G.821]).
降级分钟降级分钟是指估计错误率超过1E-6但不超过1E-3的分钟（见G.821[CCITT-G.821]）。
Degraded Minutes are determined by collecting all of the Available Seconds, removing any Severely Errored Seconds grouping the result in 60-second long groups and counting a 60- second long group (a.k.a., minute) as degraded if the cumulative errors during the seconds present in the group exceed 1E-6. Available seconds are merely those seconds which are not Unavailable as described below.
通过收集所有可用秒数，删除任何严重错误的秒数，将结果分组为60秒长的组，并将60秒长的组（也称为分钟）计算为降级，如果组中存在的秒数累积错误超过1E-6，则确定降级分钟数。可用秒数仅指不可用的秒数，如下所述。
Unavailable Seconds (UAS) Unavailable Seconds (UAS) are calculated by counting the number of seconds that the interface is unavailable. The DS1 interface is said to be unavailable from the onset of 10 contiguous SESs, or the onset of the condition leading to a failure (see Failure States). If the condition leading to the failure was immediately preceded by one or more contiguous SESs, then the DS1 interface unavailability starts from the onset of these SESs. Once unavailable, and if no failure is present, the DS1 interface becomes available at the onset of 10 contiguous seconds with no SESs. Once unavailable, and if a failure is present, the DS1 interface becomes available at the onset of 10 contiguous seconds with no SESs, if the failure clearing time is less than or equal to 10 seconds. If the failure clearing time is more than 10 seconds, the DS1 interface becomes available at the onset of 10 contiguous seconds with no SESs, or the onset period leading to the successful clearing condition, whichever occurs later. With respect to the DS1 error counts, all counters are incremented while the DS1 interface is deemed available. While the interface is deemed unavailable, the only count that is incremented is UASs.
不可用秒数（UAS）不可用秒数（UAS）通过计算接口不可用的秒数来计算。据称，DS1接口在10个连续SES开始时不可用，或在导致故障的条件开始时不可用（参见故障状态）。如果导致故障的条件之前紧接着有一个或多个连续的SES，则DS1接口不可用性从这些SES开始时开始。一旦不可用且不存在故障，DS1接口在连续10秒开始时变为可用，且无SES。一旦不可用，并且出现故障，如果故障清除时间小于或等于10秒，则DS1接口在连续10秒开始时变为可用，且无SES。如果故障清除时间超过10秒，则DS1接口在连续10秒开始时（无SES）可用，或在导致成功清除条件的开始期间（以较晚发生者为准）可用。关于DS1错误计数，当DS1接口被视为可用时，所有计数器都会递增。当该接口被视为不可用时，唯一增加的计数是UAS。
Note that this definition implies that the agent cannot determine until after a ten second interval has passed whether a given one-second interval belongs to available or unavailable time. If the agent chooses to update the various performance statistics in real time then it must be prepared to retroactively reduce the ES, BES, SES, and SEFS counts by 10 and increase the UAS count by 10 when it determines that available time has been entered. It must also be prepared to adjust the PCV count and the DM count as necessary since these parameters are not accumulated during unavailable time. It must be similarly prepared to retroactively decrease the UAS count by 10 and increase the ES, BES, and DM counts as necessary upon entering available time. A special case exists when the 10 second period leading to available or unavailable time crosses a
请注意，此定义意味着，在经过10秒的间隔之后，代理才能确定给定的1秒间隔属于可用时间还是不可用时间。如果代理选择实时更新各种性能统计数据，则必须准备追溯性地将ES、BES、SES和SEF计数减少10，并在确定已输入可用时间时将UAS计数增加10。还必须准备根据需要调整PCV计数和DM计数，因为这些参数在不可用时间内不会累积。同样，在输入可用时间后，必须准备追溯性地将UAS计数减少10，并根据需要增加ES、BES和DM计数。当导致可用或不可用时间的10秒时间跨越
900 second statistics window boundary, as the foregoing description implies that the ES, BES, SES, SEFS, DM, and UAS counts the PREVIOUS interval must be adjusted. In this case successive GETs of the affected dsx1IntervalSESs and dsx1IntervalUASs objects will return differing values if the first GET occurs during the first few seconds of the window.
900秒统计窗口边界，如上所述意味着必须调整前一间隔的ES、BES、SES、SEF、DM和UAS计数。在这种情况下，如果第一次获取发生在窗口的前几秒钟，则受影响的DSX1Intervaless和dsx1IntervalUASs对象的连续获取将返回不同的值。
The agent may instead choose to delay updates to the various statistics by 10 seconds in order to avoid retroactive adjustments to the counters. A way to do this is sketched in Appendix B.
代理可以选择将各种统计数据的更新延迟10秒，以避免对计数器进行追溯调整。附录B中概述了实现这一点的方法。
In any case, a linkDown trap shall be sent only after the agent has determined for certain that the unavailable state has been entered, but the time on the trap will be that of the first UAS (i.e., 10 seconds earlier). A linkUp trap shall be handled similarly.
在任何情况下，只有在代理确定已进入不可用状态后，才应发送链路断开陷阱，但陷阱上的时间将是第一个UAS的时间（即，提前10秒）。应以类似方式处理连接陷阱。
According to ANSI T1.231 unavailable time begins at the _onset_ of 10 contiguous severely errored seconds -- that is, unavailable time starts with the _first_ of the 10 contiguous SESs. Also, while an interface is deemed unavailable all counters for that interface are frozen except for the UAS count. It follows that an implementation which strictly complies with this standard must _not_ increment any counters other than the UAS count -- even temporarily -- as a result of anything that happens during those 10 seconds. Since changes in the signal state lag the data to which they apply by 10 seconds, an ANSI-compliant implementation must pass the one-second statistics through a 10-second delay line prior to updating any counters. That can be done by performing the following steps at the end of each one second interval.
根据ANSI T1.231，不可用时间从10个连续严重错误秒开始，也就是说，不可用时间从10个连续SES中的第一个开始。此外，当一个接口被视为不可用时，该接口的所有计数器都被冻结，但UAS计数除外。因此，严格遵守此标准的实现必须不增加UAS计数以外的任何计数器，即使是暂时的，因为在这10秒内发生的任何事情。由于信号状态的变化使其应用的数据滞后10秒，因此符合ANSI标准的实现必须在更新任何计数器之前通过10秒延迟线传递1秒统计数据。这可以通过在每一秒间隔结束时执行以下步骤来完成。
i) Read near/far end CV counter and alarm status flags from the hardware.
i) 从硬件读取近端/远端CV计数器和报警状态标志。
ii) Accumulate the CV counts for the preceding second and compare them to the ES and SES threshold for the layer in question. Update the signal state and shift the one-second CV counts and ES/SES flags into the 10-element delay line. Note that far-end one-second statistics are to be flagged as "absent" during any second in which there is an incoming defect at the layer in question or at any lower layer.
ii）累积前一秒的CV计数，并将其与相关层的ES和SES阈值进行比较。更新信号状态，并将1秒CV计数和ES/SES标志移到10元件延迟线中。请注意，在相关层或任何较低层存在传入缺陷的任何一秒钟内，远端1秒统计数据将被标记为“不存在”。
iii) Update the current interval statistics using the signal state from the _previous_ update cycle and the one-second CV counts and ES/SES flags shifted out of the 10-element delay line.
iii）使用上一次更新周期的信号状态以及从10元件延迟线移出的1秒CV计数和ES/SES标志更新当前间隔统计信息。
This approach is further described in Appendix B.
附录B进一步描述了该方法。
The following failure states are received, or detected failures, that are reported in the dsx1LineStatus object. When a DS1 interface would, if ever, produce the conditions leading to the failure state is described in the appropriate specification.
收到或检测到dsx1LineStatus对象中报告的以下故障状态。DS1接口何时（如果有）会产生导致故障状态的条件，请参见相应的规范。
Far End Alarm Failure The Far End Alarm failure is also known as "Yellow Alarm" in the DS1 case, "Distant Alarm" in the E1 case, and "Remote Alarm" in the DS2 case.
远端报警故障远端报警故障在DS1情况下也称为“黄色报警”，在E1情况下称为“远程报警”，在DS2情况下称为“远程报警”。
For D4 links, the Far End Alarm failure is declared when bit 6 of all channels has been zero for at least 335 ms and is cleared when bit 6 of at least one channel is non-zero for a period T, where T is usually less than one second and always less than 5 seconds. The Far End Alarm failure is not declared for D4 links when a Loss of Signal is detected.
对于D4链路，当所有信道的位6为零至少335 ms时，宣布远端报警故障，当至少一个信道的位6在周期T内不为零时，清除远端报警故障，其中T通常小于1秒且始终小于5秒。当检测到信号丢失时，不宣布D4链路的远端报警故障。
For ESF links, the Far End Alarm failure is declared if the Yellow Alarm signal pattern occurs in at least seven out of ten contiguous 16-bit pattern intervals and is cleared if the Yellow Alarm signal pattern does not occur in ten contiguous 16-bit signal pattern intervals.
对于ESF链路，如果黄色报警信号模式在10个连续16位模式间隔中至少有7个出现，则宣布远端报警故障；如果黄色报警信号模式在10个连续16位模式间隔中未出现，则清除远端报警故障。
For E1 links, the Far End Alarm failure is declared when bit 3 of time-slot zero is received set to one on two consecutive occasions. The Far End Alarm failure is cleared when bit 3 of time-slot zero is received set to zero.
对于E1链路，当接收到时隙0的第3位连续两次设置为1时，将宣布远端报警故障。当接收到时隙0的第3位设置为0时，远端报警故障被清除。
For DS2 links, if a loss of frame alignment (LOF or LOS) and/or DS2 AIS condition, is detected, the RAI signal shall be generated and transmitted to the remote side.
对于DS2链路，如果检测到帧对齐丢失（LOF或LOS）和/或DS2 AIS状态，则应生成RAI信号并将其传输至远程侧。
The Remote Alarm Indication(RAI) signal is defined on m-bits as a repetition of the 16bit sequence consisting of eight binary '1s' and eight binary '0s' in m-bits(1111111100000000). When the RAI signal is not sent (in normal operation),the HDLC flag pattern (01111110) in the m-bit is sent.
远程报警指示（RAI）信号在m位上定义为16位序列的重复，该序列由m位（11111111 00000000）中的八个二进制“1”和八个二进制“0”组成。当未发送RAI信号时（在正常操作中），发送m位中的HDLC标志模式（01111110）。
The RAI failure is detected when 16 or more consecutive RAI-patterns (1111111100000000) are received. The RAI failure is cleared when 4 or more consecutive incorrect-RAI-patterns are received.
当接收到16个或更多连续RAI模式（11111111 00000000）时，检测到RAI故障。当接收到4个或更多连续不正确的RAI模式时，RAI故障被清除。
Alarm Indication Signal (AIS) Failure The Alarm Indication Signal failure is declared when an AIS defect is detected at the input and the AIS defect still exists
报警指示信号（AIS）故障当在输入端检测到AIS缺陷且AIS缺陷仍然存在时，宣布报警指示信号故障
after the Loss Of Frame failure (which is caused by the unframed nature of the 'all-ones' signal) is declared. The AIS failure is cleared when the Loss Of Frame failure is cleared. (See T1.231 Section 6.2.1.2.1)
在宣布帧失效（由“所有一个”信号的非帧特性引起）后。当帧丢失故障被清除时，AIS故障被清除。（见T1.231第6.2.1.2.1节）
An AIS defect at a 6312 kbit/s (G.704) interface is detected when the incoming signal has two {2} or less ZEROs in a sequence of 3156 bits (0.5ms). The AIS signal defect is cleared when the incoming signal has three {3} or more ZEROs in a sequence of 3156 bits (0.5ms).
当输入信号在3156位（0.5ms）的序列中有两个{2}或更少的零时，在6312 kbit/s（G.704）接口处检测到AIS缺陷。当输入信号在3156位（0.5ms）的序列中有三个{3}或更多的零时，AIS信号缺陷被清除。
Loss Of Frame Failure For DS1 links, the Loss Of Frame failure is declared when an OOF or LOS defect has persisted for T seconds, where 2 <= T <= 10. The Loss Of Frame failure is cleared when there have been no OOF or LOS defects during a period T where 0 <= T <= 20. Many systems will perform "hit integration" within the period T before declaring or clearing the failure e.g., see TR 62411 [AT&T-TR-62411].
丢失帧故障对于DS1链路，当OOF或LOS缺陷持续T秒时，宣布丢失帧故障，其中2<=T<=10。当在0<=T<=20的时间段内没有OOF或LOS缺陷时，帧丢失故障被清除。许多系统将在宣布或清除故障之前的T段时间内执行“命中集成”，例如，参见TR 62411[AT&T-TR-62411]。
For E1 links, the Loss Of Frame Failure is declared when an OOF defect is detected.
对于E1链路，当检测到OOF缺陷时，将声明帧丢失故障。
Loss Of Signal Failure For DS1, the Loss Of Signal failure is declared upon observing 175 +/- 75 contiguous pulse positions with no pulses of either positive or negative polarity. The LOS failure is cleared upon observing an average pulse density of at least 12.5% over a period of 175 +/- 75 contiguous pulse positions starting with the receipt of a pulse.
信号丢失故障对于DS1，在观察到175+/-75个连续脉冲位置且无正负极性脉冲时，宣布信号丢失故障。从接收到脉冲开始，在175+/-75个连续脉冲位置的一段时间内，观察到平均脉冲密度至少为12.5%时，服务水平故障被清除。
For E1 links, the Loss Of Signal failure is declared when greater than 10 consecutive zeroes are detected (see O.162 Section 3.4.4).
对于E1链路，当检测到大于10个连续零时，宣布信号丢失故障（见O.162第3.4.4节）。
A LOS defect at 6312kbit/s interfaces is detected when the incoming signal has "no transitions", i.e., when the signal level is less than or equal to a signal level of 35dB below nominal, for N consecutive pulse intervals, where 10 <=N<=255.
当输入信号“无过渡”时，即当信号电平小于或等于低于标称值35dB的信号电平时，在N个连续脉冲间隔内，检测到6312kbit/s接口的服务水平缺陷，其中10<=N<=255。
The LOS defect is cleared when the incoming signal has "transitions", i.e., when the signal level is greater than or equal to a signal level of 9dB below nominal, for N consecutive pulse intervals, where 10<=N<=255.
当输入信号具有“过渡”时，即当信号电平大于或等于低于标称值9dB的信号电平时，在N个连续脉冲间隔内，服务水平缺陷被清除，其中10<=N<=255。
A signal with "transitions" corresponds to a G.703 compliant signal.
具有“转换”的信号对应于G.703兼容信号。
Loopback Pseudo-Failure The Loopback Pseudo-Failure is declared when the near end equipment has placed a loopback (of any kind) on the DS1. This allows a management entity to determine from one object whether the DS1 can be considered to be in service or not (from the point of view of the near end equipment).
环回伪故障当近端设备在DS1上放置环回（任何类型）时，宣布环回伪故障。这允许管理实体从一个对象确定DS1是否可以被视为在使用中（从近端设备的角度）。
TS16 Alarm Indication Signal Failure For E1 links, the TS16 Alarm Indication Signal failure is declared when time-slot 16 is received as all ones for all frames of two consecutive multiframes (see G.732 Section 4.2.6). This condition is never declared for DS1.
对于E1链路的TS16报警指示信号故障，当接收到两个连续多帧的所有帧的所有时隙16时，宣布TS16报警指示信号故障（参见G.732第4.2.6节）。从未为DS1声明此条件。
Loss Of MultiFrame Failure The Loss Of MultiFrame failure is declared when two consecutive multiframe alignment signals (bits 4 through 7 of TS16 of frame 0) have been received with an error. The Loss Of Multiframe failure is cleared when the first correct multiframe alignment signal is received. The Loss Of Multiframe failure can only be declared for E1 links operating with G.732 [CCITT-G.732] framing (sometimes called "Channel Associated Signalling" mode).
丢失多帧故障当接收到两个连续的多帧对齐信号（第0帧TS16的第4位到第7位）时，出现错误，则宣布丢失多帧故障。当接收到第一个正确的多帧对准信号时，多帧故障的丢失被清除。多帧故障的丢失只能针对使用G.732[CCITT-G.732]帧（有时称为“信道相关信令”模式）运行的E1链路进行声明。
Far End Loss Of Multiframe Failure The Far End Loss Of Multiframe failure is declared when bit 2 of TS16 of frame 0 is received set to one on two consecutive occasions. The Far End Loss Of Multiframe failure is cleared when bit 2 of TS16 of frame 0 is received set to zero. The Far End Loss Of Multiframe failure can only be declared for E1 links operating in "Channel Associated Signalling" mode (See G.732).
多帧故障的远端丢失当连续两次接收到帧0的TS16的位2设置为1时，宣布多帧故障的远端丢失。当接收到帧0的TS16的位2设置为零时，清除多帧故障的远端丢失。只有在“信道相关信令”模式下运行的E1链路才能声明多帧故障的远端丢失（见G.732）。
DS2 Payload AIS Failure The DS2 Payload AIS is detected when the incoming signal of the 6,312 kbps frame payload (time-slots 1 through 96) has 2 or less 0's in a sequence of 3072 bits (0.5ms). The DS2 Payload AIS is cleared when the incoming signal of the 6,312 kbps frame payload has 3 or more 0's in a sequence of 3072 bits (0.5 ms).
DS2有效负载AIS故障当6312 kbps帧有效负载（时隙1至96）的输入信号在3072位（0.5ms）的序列中具有2个或更少的0时，检测到DS2有效负载AIS。当6312 kbps帧有效负载的输入信号在3072位（0.5 ms）的序列中具有3个或更多0时，DS2有效负载AIS被清除。
DS2 Performance Threshold DS2 Performance Threshold Failure monitors equipment performance and is based on the CRC (Cyclic Redundancy Check) Procedure defined in G.704.
DS2性能阈值DS2性能阈值故障监控设备性能，并基于G.704中定义的CRC（循环冗余校验）程序。
The DS2 Performance Threshold Failure is detected when the bit error ratio exceeds 10^-4 (Performance Threshold), and the DS2 Performance Threshold Failure shall be cleared when the bit error ratio decreased to less than 10^-6."
当误码率超过10^-4（性能阈值）时，检测到DS2性能阈值故障，当误码率降至10^-6以下时，应清除DS2性能阈值故障。”
Circuit Identifier This is a character string specified by the circuit vendor, and is useful when communicating with the vendor during the troubleshooting process (see M.1400 [ITU-T-M.1400] for additional information).
电路标识符这是电路供应商指定的字符串，在故障排除过程中与供应商通信时非常有用（更多信息请参见M.1400[ITU-T-M.1400]）。
Proxy In this document, the word proxy is meant to indicate an application which receives SNMP messages and replies to them on behalf of the devices which implement the actual DS1/E1 interfaces. The proxy may have already collected the information about the DS1/E1 interfaces into its local database and may not necessarily forward the requests to the actual DS1/E1 interface. It is expected in such an application that there are periods of time where the proxy is not communicating with the DS1/E1 interfaces. In these instances the proxy will not necessarily have up-to-date configuration information and will most likely have missed the collection of some statistics data. Missed statistics data collection will result in invalid data in the interval table.
Proxy在本文档中，Proxy一词表示代表实现实际DS1/E1接口的设备接收SNMP消息并回复这些消息的应用程序。代理可能已经将有关DS1/E1接口的信息收集到其本地数据库中，并且不一定将请求转发到实际的DS1/E1接口。在这种应用程序中，预期存在代理不与DS1/E1接口通信的时间段。在这些情况下，代理不一定具有最新的配置信息，并且很可能错过了一些统计数据的收集。未收集统计数据将导致间隔表中的数据无效。

dsx1JBZS refers the Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8 bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per channel, or 1.344 Mbps, is available for data.
dsx1JBZS是指干扰位零抑制，其中AT&T规定每8位周期至少有一个脉冲，实际上是通过在每个通道的第8位强制一个脉冲来实现的。因此，每个通道只有7位或1.344 Mbps可用于数据。
dsx1B8ZS refers to the use of a specified pattern of normal bits and bipolar violations which are used to replace a sequence of eight zero bits.
dsx1B8ZS是指使用指定模式的正常位和双极违规，用于替换八个零位序列。
ANSI Clear Channels may use dsx1ZBTSI, or Zero Byte Time Slot Interchange.
ANSI清除通道可使用dsx1ZBTSI或零字节时隙交换。
E1 links, with or without CRC, use dsx1HDB3 or dsx1AMI.
E1链路，带或不带CRC，使用dsx1HDB3或dsx1AMI。
dsx1AMI refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data which meets or exceeds the pulse density requirements, such as inverting HDLC data. dsx1B6ZS refers to the user of a specified pattern of normal bits and bipolar violations which are used to replace a sequence of six zero bits. Used for DS2."
dsx1AMI指的是不存在零码抑制且行编码不能直接解决问题的模式。在该应用中，较高的层必须提供满足或超过脉冲密度要求的数据，例如反转HDLC数据。dsx1B6ZS是指指定模式的正常位和双极违规的用户，用于替换六个零位序列。用于DS2。”

The table was mandatory for systems dividing a DS1 into channels containing different data streams that are of local interest. Systems which are indifferent to data content, such as CSUs, need not implement it.
该表对于将DS1划分为包含本地感兴趣的不同数据流的通道的系统是必需的。与数据内容无关的系统，如CSU，不需要实现它。
The DS1 fractional table identifies which DS1 channels associated with a CSU are being used to support a logical interface, i.e., an entry in the interfaces table from the Internet-standard MIB.
DS1分数表标识与CSU相关联的哪些DS1通道用于支持逻辑接口，即来自Internet标准MIB的接口表中的条目。
For example, consider an application managing a North American ISDN Primary Rate link whose division is a 384 kbit/s H1 _B_ Channel for Video, a second H1 for data to a primary routing peer, and 12 64 kbit/s H0 _B_ Channels. Consider that some subset of the H0 channels are used for voice and the remainder are available for dynamic data calls.
例如，考虑管理北美ISDN初级速率链路的应用，其划分为视频的384 kb/s H1×By信道、第二H1数据到主路由对等点，以及12个64 kB/s H0×By信道。考虑到H0信道的一些子集用于语音，其余部分可用于动态数据呼叫。
We count a total of 14 interfaces multiplexed onto the DS1 interface. Six DS1 channels (for the sake of the example, channels 1..6) are used for Video, six more (7..11 and 13) are used for data, and the remaining 12 are in channels 12 and 14..24.
我们总共统计了14个多路复用到DS1接口上的接口。六个DS1通道（为了示例，通道1..6）用于视频，另外六个（7..11和13）用于数据，其余12个在通道12和14..24中。
Let us further imagine that ifIndex 2 is of type DS1 and refers to the DS1 interface, and that the interfaces layered onto it are numbered 3..16.
让我们进一步设想ifIndex 2属于DS1类型，并引用DS1接口，并且其上分层的接口编号为3..16。

There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. The specific objects and their sensitivities/vulnerabilities are as follows.
此MIB模块中定义了许多管理对象，其MAX-ACCESS子句为read-write。在某些网络环境中，此类对象可能被视为敏感或易受攻击。在没有适当保护的非安全环境中支持SET操作可能会对网络操作产生负面影响。具体对象及其敏感性/脆弱性如下所示。
Setting the following objects to incorrect values may result in traffic interruptions:
将以下对象设置为不正确的值可能会导致交通中断：
dsx1LineType dsx1LineCoding dsx1SendCode dsx1LoopbackConfig dsx1SignalMode dsx1TransmitClockSource dsx1Fdl dsx1LineLength dsx1Channelization dsx1LineMode dsx1LineBuildOut
dsx1LineType dsx1LineCoding dsx1SendCode dsx1LoopbackConfig dsx1SignalMode DSX1TransmitLockSource dsx1Fdl dsx1LineLength dsx1Channelization dsx1LineMode dsx1LineBuildOut
In the case of dsx1LineType, for example, both ends of a DS1/E1 must have the same value in order for traffic to flow. In the case of dsx1SendCode and dsx1LoopbackConfig, for another example, traffic may stop transmitting when particular loopbacks are applied.
例如，在dsx1LineType的情况下，DS1/E1的两端必须具有相同的值才能使流量流动。例如，在dsx1SendCode和dsx1LoopbackConfig的情况下，当应用特定的环回时，通信量可能会停止传输。
Setting the following object to an incorrect value will not harm the traffic, but it may cause a circuit to be mis-identified and thereby create difficulties for service personnel when attempting to troubleshoot a problem:
将以下对象设置为不正确的值不会影响通信量，但可能会导致错误识别电路，从而给维修人员在尝试故障排除时带来困难：
dsx1CircuitIdentifier
DSX14电路标识符
Setting the following object can cause an increase in the number of traps received by the network management station:
设置以下对象可能导致网络管理站接收的陷阱数量增加：
dsx1LineStatusChangeTrapEnable
DSX1lineStatusChangeTrappenable
The readable objects in this MIB module (i.e., the objects with a MAX-ACCESS other than not-accessible) may be considered sensitive in some environments since, collectively, they provide extensive information about the performance of interfaces in DS1/E1/DS2/E2 equipment or networks and can reveal some aspects of their configuration. In such environments, it is important to control even GET and NOTIFY access to these objects and possibly to encrypt the values of these objects when sending them over the network via SNMP.
在某些环境中，此MIB模块中的可读对象（即具有MAX-ACCESS而非not ACCESS的对象）可能被视为敏感对象，因为它们共同提供了有关DS1/E1/DS2/E2设备或网络中接口性能的广泛信息，并可揭示其配置的某些方面。在这种环境中，通过SNMP通过网络发送这些对象时，控制甚至获取和通知对这些对象的访问，并可能加密这些对象的值，这一点很重要。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
SNMPv3之前的SNMP版本未包含足够的安全性。即使网络本身是安全的（例如通过使用IPSec），即使如此，也无法控制安全网络上的谁可以访问和获取/设置（读取/更改/创建/删除）此MIB模块中的对象。
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
建议实施者考虑SNMPv3框架所提供的安全特性（参见[RCFC310]，第8节），包括对SNMPv3加密机制的完全支持（用于身份验证和隐私）。
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
此外，不建议部署SNMPv3之前的SNMP版本。相反，建议部署SNMPv3并启用加密安全性。然后，客户/运营商应负责确保授予访问此MIB模块实例权限的SNMP实体已正确配置为仅授予那些拥有确实获取或设置（更改/创建/删除）对象的合法权限的主体（用户）访问对象。

Appendix A - Use of dsx1IfIndex and dsx1LineIndex
附录A-DSX1iIndex和dsx1LineIndex的使用
This Appendix exists to document the previous use if dsx1IfIndex and dsx1LineIndex and to clarify the relationship of dsx1LineIndex as defined in RFC 1406 with the dsx1LineIndex as defined in this document.
本附录旨在记录DSX1iIndex和dsx1LineIndex之前的使用情况，并澄清RFC 1406中定义的dsx1LineIndex与本文档中定义的dsx1LineIndex之间的关系。
The following shows the old and new definitions and the relationship:
以下显示了新旧定义及其关系：
[New Definition]: "This object should be made equal to ifIndex. The next paragraph describes its previous usage. Making the object equal to ifIndex allows proper use of ifStackTable and ds0/ds0bundle mibs.
[新定义]：“此对象应与ifIndex相等。下一段描述其以前的用法。将此对象与ifIndex相等可以正确使用ifStackTable和ds0/ds0bundle MIB。
[Old Definition]: "This object is the identifier of a DS1 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS1 interface, it should have the same value as ifIndex. Otherwise, number the dsx1LineIndices with an unique identifier following the rules of choosing a number that is greater than ifNumber and numbering the inside interfaces (e.g., equipment side) with even numbers and outside interfaces (e.g., network side) with odd numbers."
[旧定义]：“此对象是受管设备上DS1接口的标识符。如果有一个ifEntry直接与此接口关联，并且仅与此DS1接口关联，则其值应与ifIndex相同。否则，请使用唯一标识符对DSX1LineIndex进行编号，并遵循以下规则：选择一个大于ifNumber的编号，并使用偶数对内部接口（例如，设备侧）进行编号，使用奇数对外部接口（例如，网络侧）进行编号。”
When the "Old Definition" was created, it was described this way to allow a manager to treat the value _as if_ it were and ifIndex, i.e., the value would either be: 1) an ifIndex value or 2) a value that was guaranteed to be different from all valid ifIndex values.
创建“旧定义”时，这样描述是为了允许管理者将该值视为是和ifIndex，即该值可以是：1）ifIndex值或2）保证与所有有效ifIndex值不同的值。
The new definition is a subset of that definition, i.e., the value is always an ifIndex value.
新定义是该定义的子集，即该值始终是ifIndex值。
The following is Section 3.1 from RFC 1406:
以下为RFC 1406第3.1节：
Different physical configurations for the support of SNMP with DS1 equipment exist. To accommodate these scenarios, two different indices for DS1 interfaces are introduced in this MIB. These indices are dsx1IfIndex and dsx1LineIndex.
存在不同的物理配置以支持DS1设备的SNMP。为了适应这些场景，此MIB中引入了DS1接口的两个不同索引。这些索引是DSX1iIndex和dsx1LineIndex。
External interface scenario: the SNMP Agent represents all managed DS1 lines as external interfaces (for example, an Agent residing on the device supporting DS1 interfaces directly):
外部接口方案：SNMP代理将所有受管DS1线路表示为外部接口（例如，驻留在直接支持DS1接口的设备上的代理）：
For this scenario, all interfaces are assigned an integer value equal to ifIndex, and the following applies:
对于此场景，所有接口都被分配一个等于ifIndex的整数值，并且以下情况适用：
ifIndex=dsx1IfIndex=dsx1LineIndex for all interfaces.
所有接口的ifIndex=dsx1IfIndex=dsx1LineIndex。
The dsx1IfIndex column of the DS1 Configuration table relates each DS1 interface to its corresponding interface (ifIndex) in the Internet-standard MIB (MIB-II STD 17, RFC 1213) [RFC1213].
DS1配置表的DSX1iIndex列将每个DS1接口与其在Internet标准MIB（MIB-II STD 17，RFC 1213）[RFC1213]中的相应接口（iIndex）相关联。
External&Internal interface scenario: the SNMP Agents resides on an host external from the device supporting DS1 interfaces (e.g., a router). The Agent represents both the host and the DS1 device. The index dsx1LineIndex is used to not only represent the DS1 interfaces external from the host/DS1-device combination, but also the DS1 interfaces connecting the host and the DS1 device. The index dsx1IfIndex is always equal to ifIndex.
外部和内部接口方案：SNMP代理驻留在支持DS1接口的设备（例如路由器）外部的主机上。代理表示主机和DS1设备。索引dsx1LineIndex不仅用于表示主机/DS1设备组合外部的DS1接口，还用于表示连接主机和DS1设备的DS1接口。索引dsx1IfIndex始终等于ifIndex。
Example:
例子：
A shelf full of CSUs connected to a Router. An SNMP Agent residing on the router proxies for itself and the CSU. The router has also an Ethernet interface:
装满连接到路由器的CSU的架子。驻留在路由器上的SNMP代理为其自身和CSU代理。路由器还具有以太网接口：

The assignment of the index values could for example be:
例如，索引值的分配可以是：
ifIndex (= dsx1IfIndex) dsx1LineIndex 1 NA NA (Ethernet) 2 Line#A Router Side 6 2 Line#A Network Side 7 3 Line#B Router Side 8 3 Line#B Network Side 9 4 Line#C Router Side 10 4 Line#C Network Side 11 5 Line#D Router Side 12 5 Line#D Network Side 13
iIndex（=DSX1iIndex）dsx1LineIndex 1 NA（以太网）2线#路由器侧6 2线#网络侧7 3线#路由器侧8 3线#B网络侧9 4线#C路由器侧10 4线#C网络侧11 5线#D路由器侧12 5线#D网络侧13
For this example, ifNumber is equal to 5. Note the following description of dsx1LineIndex: the dsx1LineIndex identifies a DS1 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS1 interface, it should have the same value as ifIndex. Otherwise, number the dsx1LineIndices with an unique identifier following the rules of choosing a number greater than ifNumber and numbering inside interfaces (e.g., equipment side) with even numbers and outside interfaces (e.g., network side) with odd numbers.
对于本例，ifNumber等于5。注意dsx1LineIndex的以下描述：dsx1LineIndex标识受管设备上的DS1接口。如果有一个ifEntry直接与此接口关联，并且仅与此DS1接口关联，则其值应与ifIndex相同。否则，请使用唯一标识符对DSX1LineIndex进行编号，并遵循以下规则：选择大于ifNumber的数字，并使用偶数对内部接口（如设备侧）进行编号，使用奇数对外部接口（如网络侧）进行编号。
If the CSU shelf is managed by itself by a local SNMP Agent, the situation would be:
如果CSU托架由本地SNMP代理自行管理，则情况如下：
ifIndex (= dsx1IfIndex) dsx1LineIndex 1 Line#A Network Side 1 2 Line#A RouterSide 2 3 Line#B Network Side 3 4 Line#B RouterSide 4 5 Line#C Network Side 5 6 Line#C Router Side 6 7 Line#D Network Side 7 8 Line#D Router Side 8
iIndex（=DSX1iIndex）dsx1LineIndex 1线#网络侧12线#路由侧23线#B网络侧34线#B路由侧45线#C网络侧56线#C路由器侧67线#D网络侧78线#D路由器侧8线#
Appendix B - The delay approach to Unavailable Seconds.
附录B-不可用秒的延迟方法。
This procedure is illustrated below for a DS1 ESF interface. Similar rules would apply for other DS1, DS2, and E1 interface variants. The procedure guarantees that the statistical counters are correctly updated at all times, although they lag real time by 10 seconds. At the end of each 15 minutes interval the current interval counts are transferred to the most recent interval entry and each interval is shifted up by one position, with the oldest being discarded if necessary in order to make room. The current interval counts then start over from zero. Note, however, that the signal state calculation does not start afresh at each interval boundary; rather, signal state information is retained across interval boundaries.
以下说明了DS1 ESF接口的此过程。类似的规则也适用于其他DS1、DS2和E1接口变体。该过程确保统计计数器始终正确更新，尽管它们实时滞后10秒。在每个15分钟间隔结束时，当前间隔计数被转移到最近的间隔条目，每个间隔被上移一个位置，如果必要，为了腾出空间，最早的间隔被丢弃。然后，当前间隔计数从零开始。然而，请注意，信号状态计算不会在每个间隔边界处重新开始；相反，信号状态信息跨区间边界保留。

Note that if such a procedure is adopted there is no current interval data for the first ten seconds after a system comes up. noSuchInstance must be returned if a management station attempts to access the current interval counters during this time.
请注意，如果采用这种程序，则在系统启动后的前十秒钟内没有当前间隔数据。如果管理站在此期间尝试访问当前间隔计数器，则必须返回noSuchInstance。
It is an implementation-specific matter whether an agent assumes that the initial state of the interface is available or unavailable.
代理是否假定接口的初始状态可用或不可用是实现特有的问题。
