This chapter describes the system maintenance and monitoring capabilities available in the Element Management System (EMS), and includes the following sections:
EMS provides the following information about your NE, its plugin cards, and EMS.
To display the version of EMS software currently running on a workstation, select Help > Version from either the net view or node view. EMS displays the date and release number of the software in use.
To display information about a particular NE, launch the node view, and double-click the nameplate to launch the NE provision window. (See Figure 16-1.) Information provided includes:
To display information about a particular line card or common card, select Objects > Plugin Card Detail Information from the node view menu bar. EMS displays the plugin card provision window. (See Figure 16-2.) Information provided includes:
The Cisco 6732 metallic test access card (MTAC) offers an RS-232 interface for local access through an EMS workstation. See the application note RS-232 Connection for the workstation provisioning procedure.
To provision the MTAC RS-232 port, perform the following steps starting in node view:
Step 2 Set the following parameters according to your connection:
Step 3 Click Apply to provision the MTAC RS-232interface.
The Ethernet port on the Cisco IAD1101 and on the Cisco 6705 main control card (MCC) can be shut down to secure the NE and prevent unauthorized system access.
 |
Caution Placing the Ethernet port out of service should only be performed after all provisioning is complete. You cannot communicate with the NE if this port is disabled, and a solid inter node data link (INDL) has not been established between the NE in question and a remote NE. |
To place the Ethernet port out of service, perform the following steps starting in node view:
Step 2 Set the Admin Status of the Ethernet port to OutOfService.
Step 3 Click Apply to put the Ethernet port out of service. EMS displays a warning message. (See Figure 16-5.)
Step 4 Press Yes to disable the Ethernet port.
|
Caution After the Ethernet port is disabled, the port will be inoperable until a remote instruction to place the port in service is made from an EMS workstation using an INDL. |
Performance monitoring is the action of collecting data on the signal over a period of time to detect degradations in the section, line, or path. The parameters that are collected are based on signal integrity, number of protection switches, and number of failures.
Table 16-1: through Table 16-6: show the codes for monitoring degradations on sections, lines and paths.
| PM Code | Definition | Description |
|---|---|---|
CV-L | Coding violations - line | The count of BPVs and EXZs occurring over the accumulation period. An EXZ increments the CV-L by one, regardless of the length of the zero string. For a B8ZS-coded signal, BPVs that are part of the zero substitution code are excluded from the count. |
ES-L | Errored seconds - line | The count of seconds during which one or more of the following has occurred: BPVs, EXZs and LOSs. For a B8ZS-coded signal, BPVs that are part of the zero substitution code are excluded. |
SES-L | Severely errored seconds - line | The count of seconds during which 1,544 or more BPVs or EXZs, or one or more LOS defects, have occurred. |
CV-P | Coding violations - path | For DS1-ESF paths, this parameter is a count of detected CRC-6 defects. For DS1-SF Paths, this parameter is a count of defected FEs. |
CSS-P | Controlled slip seconds - path | Only applies to DS1 extensions and Multiple Interface Group Features. This parameter is a count of seconds during which a CS has occurred. Counts of CSs can be accurately made only in the NE in which the DS1 signal CS took place. |
ES-P | Errored seconds - path | For DS1-ESF, this parameter is a count of one-second intervals containing one or more CRC-6 errors or one or more CS events, or one or more SEF or AIS defects. In the case of DS1 SF, this parameter is a count of one second intervals containing one or more FE events, or one or more CS events, or one or more SEF or AIS defects. |
FC-P | Failure count - path | The number of LOS/LOF/AIS-L (near end) or RDI-L (far end) failures. Count is incremented only when the failure goes from off to on. |
PSC-P | Protection switch count - path | The number of switches between working and protect fibers when in 1+1 linear mode. |
PSD-P | Protection switch duration - path | The number of seconds that the facility has been on the protection fiber. Only applicable if revertive line switching is used. |
SAS-P | Severely errored frame/alarm indication signal - path | The number of seconds containing one or more SEFs or one or more AIS defects. |
SES-P | Severely errored seconds - path | For DS1-ESF paths, this parameter is a count of seconds during which at least one of the following has occurred: 320 or more CRC-6 errors, or one or more SEF or AIS defects. For DS1-SF paths, an SES is a second containing either the occurrence of eight FEs (if both Ft and Fs bits are considered), four FEs (if only Ft bits are considered), or one or more SEF or AIS defects. |
SEFS-P | Severely errored frame seconds - path | A count of seconds containing one or more SEFs or one or more AIS defects. |
UAS-P | Unavailable seconds - path | A count of one-second intervals during which the DS1 path is unavailable. A DS1 path is said to be unavailable at the onset of ten contiguous SESs. The 10 SESs are included in unavailable time. Once unavailable, the DS1 path becomes available at the one set 10 consecutive seconds with no SESs. The 10 seconds with no SESs are excluded from unavailable time. |

SES-S | Severely errored seconds - section | Number of seconds during which 155 or more BIP errors occurred or an SEF/LOS was present. |
