爱立信软交换培训教材（MGW部分

用于储存CV配置备份的文件及文件夹如下： /d/configuration/cv/ directories /d/cv.ptr file 网元的配置软交换网络的mgw，包含存在板子里面的读取模块的版本信息，都被保存在一篙库里。这篙库加上一些其它文件就是一该版本（configuration version），即CV。CV文件保存在如下子文件夹里： /d/configuration/cv/.

/d/cv.ptr这羹包含了当前被加载的CV文件名称。

第二章 数据配置

第一节 相关概念

要理解MGW之中釜素，先应理解Managed Object Model（MOM）的概念。在爱立信MGW中，所有的元素都可以理解为一富管理对螼）。爱立信的MGW就是一杠理对希型架构。网元通过MO的建立跟修改来被管理。

MO被按照改抽显按一定的顺绣。窸之间有一定的交互关系。MO的分类，特性跟不同分类之间的关系就被定义为了MO模型（MOM）。另外一些信息，比如容量，车，规寓，值余互之间的逻辑关系均被说肙M定义了网元管理的信息建模，呈现了一种网元资源参数跟行为的管控方法。

MO依据一定的命名规远，所有的MO都有一竘assNameId的命名标志。MO按照彼此的守系，可以根据逝列。如下图图示：

Mo的命名标志有两种，一窪N（Relative Distinguished Name），另一窪N（Local Distinguished Name）。前者为相对名，邯绝对名。比如上图RDN为SubrackId=1的LDN即为ManagedElement=1,Equipment=1,Subrack=1 .。

所有的MO都有一些通用尸如下表所示： operationalState The attribute, operationalState specifies whether the MO is working (ENABLED) or failed (DISABLED). These values are set automatically and are broadcast to the MO instances from the resource. The operationalState is used by all MOs that can fail. The possible values of this attribute are: DISABLED ENABLED administrativeState The attribute, administrativeState indicates whether the MO can be used. The possible values of this attribute are: LOCKED - use of this MO is not allowed. UNLOCKED - use of this MO is allowed. SHUTTING_DOWN - no new users are accepted. The attribute, availabilityStatus , contains details about availabilityStatus operationalState . It indicates why the operational state has changed its value to DISABLED. The availabilityStatus can either take one value or a list of values. In the first case, the most prioritized reason for the operationalState to be DISABLED is shown. In the second case, all the reasons are shown. The availabilityStatus is either: an enumeration a list of enumerations or a bit map (set-valued integer) The enumeration contains the values defined below. Other combinations of these values can also occur in the bit map. NO_STATUS - indicates no additional information. IN_TEST - indicates why disturbances or reduced capacity can occur when the operationalState is ENABLED. FAILED - indicates why the operationalState has changed its value to DISABLED. POWER_OFF - indicates why the operationalState has changed its value to DISABLED. OFF_LINE - indicates why the operationalState has changed its value to DISABLED. OFF_DUTY - indicates why the operationalState has changed its value to DISABLED. DEGRADED - indicates why disturbances or reduced capacity can occur when the operationalState is ENABLED. NOT_INSTALLED - indicates why the operationalState has changed its value to DISABLED. LOG_FULL - indicates that the command log is full. DEPENDENCY_LOCKED - indicates that the operationalState for the MO has changed its value as a result of a resource on which it depends being locked. DEPENDENCY_FAILED - indicates a dependency fault, that is, a resource that the MO depends on has failed. DEPENDENCY_SHUTTINGDOWN - indicates that shutting-down is in progress in a dependent resource. userLabel You can specify an arbitrary label for the MO instance in the attribute, userLabel. Note: Do not use this attribute for identifying MOs, as the value of this attribute is not unique. The attribute, reservedBy specifies the identity of the MO or MOs that have a reference to this MO, and is used to keep track of relationships between MOs in the node. The referencing MO, which can be a ManagedObject type or a specific MO type, sets the attribute, reservedBy. Note: It is not possible to delete an MO that is reserved by reservedBy another MO. 爱立信的MGW是一岗JAVA的系统。Mo的建立，参数设置和删除都有一定的告范。按照特定的告范编写的用于MO创建，修改和删除的命令集就是Command File恍拙（Script）。

编写完成脚本文件黑EMAS中点开Configuration-RunCommand File，就弹撑本运行界面。

点粀se按钮选元运行的Script文件，再勾选Halt on errors和Verbose logging，之簉t按钮，Script文件即开始运行。如果优本中的Command编写错吾自动中止并在Parameters窗口中标稠的位置软交换网络的mgw，在Logging窗口中会有Command的运行Log纪录。

第二节 TDM传输物理定义

TDM传输的物理连接，可分为PCM直连跟STM-1连接两种方法。PCM直连模式使用ETMC1板(每板提供8?，STM-1连接方法使用ETM1板（每板提供1窶 STM-1接口）。目前江苏爱立信所用的方法均为STM-1连接模式。

定义E1PhysPathTerm（PCM直连）

定义Os155SpiTtp（STM-1连接） 定义Ds0Bundle 1．定义E1PhysPathTerm （PCM直连方式）

Motype : E1PhysPathTerm

此类MO描是节点的一?例如 2 Mbit/s)物理接口. 但E1PhysPathTerm MO并未定义此物理接口支持某种承载方式(可以是TDM?.

有关定义承载方式的具体信息，请参照下列对夏描蔇s0Bundle, AtmPort, IMALink and IMAGroup）.

Possible parents: ExchangeTerminal; Possible children: Ds0Bundle [0..31]; References to:

AtmPort; ImaLink; Synchronization;

举例：

// E1PhysPathTerm 1271
