PKT-INT (Packet Interface)

■ Issue the status packet-interface command to determine the:
— Service state of the Packet Interface circuit (for example, in
service/out of service)
— Total number of Packet Interface links assigned to a Packet
Interface circuit.
For a standby IPSI’s Packet Interface circuit in a high-reliability
system (duplicated IPSIs), the circuit (if not out of service due to a
failure condition) is shown in “standby” mode. The number of links
for a standby Packet Interface circuit is always zero.
In general, if every link for an active IPSI’s Packet Interface circuit is shown
as a “Failed Link,” there may be a fault on either the Packet Interface circuit
or the packet bus that caused every link to go down. If only a small
percentage of the links are shown as “Failed Links,” then the Packet
Interface circuit is probably not the source of the problem. Some typical
sources of individual link failures include a:
■ Failed BRI telephone set
■ Disconnected cord to a BRI set (causes three link failures)
For a case where not every link appears in the “Failed Links” category,
examine the alarm and error logs for failures of the following circuit packs,
and follow the repair procedures for those circuit packs before considering
replacing the associated IPSI circuit pack:
■ ISDN-BRI Line circuit packs, ports, and stations (BRI-BD,
BRI-PORT, BRI-SET)
■ Universal DS1 circuit packs and ports (UDS1-BD, TIE-DS1)
■ TN464C, TN2207, TN2464 Universal DS1 circuit pack — ISDN-PRI
service
■ TN556, TN2198, TN2185 ISDN-BRI Line circuit pack — ISDN-BRI
service
■ TN2305, TN2306 ATM
■ TN799 Control LAN (C-LAN) packet port circuit pack
■ TN2501 Voice Announcements over the LAN (VAL)
Use the test sys-link command with the faulted path option to test all
components in the faulted link.
