■ Packet Circuit Pack Maintenance
The operation of Packet Interface 2 affects the operation and maintenance
of other circuit packs connected to the Packet bus. Affected applications
include:
— BRI applications
— Universal DS1 applications (UDS1) using ISDN/PRI service
— C-LAN applications
— ASAI applications
Some errors of Packet circuit packs may require examination of the Packet
Interface operating status. To obtain this information, examine the Error
and Alarm Logs for PKT-INT entries. Also issue the
status
packet-interface
command to determine the service state of the Packet
Interfaces (for example, in-service/out-of-service) and information about
the total number of Packet Interface links assigned to a Packet Interface
instance. In general, if all links for Packet Interface 2 are shown in the
Failed Links
category, there may be a fault on the Packet Interface or on
the Packet Bus that caused all links to go down. If only a small percentage
of the links are shown as
Failed Links
, then the Packet Interface is
probably not the source of the problem. For example, disconnecting the
cord to a BRI set causes three link failures. Refer to Chapter 2,
‘‘Maintenance Commands’’ for more information on the
status
packet-interface
command.
For the case where not all links are in the
Failed Links
category, examine
the alarm log and error log for failures of the following circuit pack types
and follow the repair procedures for those circuit packs before
considering replacing the TN798 Processor circuit pack.
■ ISDN-BRI Line circuit packs, ports, and stations (BRI-BD,
BRI-PORT, BRI-SET, ATT-PORT, ATT-ADJ)
■ ISDN-BRI Trunk circuit pack and ports (TBRI-BD, TBRI-PT)
■ Universal DS1 circuit packs and ports (UDS1-BD, TIE-DS1)
■ DS1 Interface circuit packs and ports (DS1-BD, TIE-DS1)
■ C-LAN circuit packs and ports (CLAN-BD, RSCL-PT, PPP-PT,
ETH-PT)
■ ASAI circuit packs and ports (ASAI-BD, ASAI-PT, ASAI-ADJ,
ASAI-EPT, LGATE-BD, LGATE-PT, LGATE-AJ, ATTE-PT, ATTE-AJ,
MAPD-BD)
■ Media Processor circuit pack (MEDPRO, MEDPRO-RES)
