CAUTION:
The ‘‘Packet Bus Fault Isolation and Repair’’ for isolating and resolving
Packet Bus faults is included in Chapter 5, ‘‘Alarms, Errors, and
Troubleshooting’’. This flowchart, along with the other information presented
in the chapter, can help resolve problems that involve more than a single
station or circuit pack. Refer to this section whenever the repair procedures
for this Maintenance Object refer to Packet Bus and/or Packet Control
maintenance.
This section relates to the TN556 ISDN BRI, TN2198 ISDN BRIU, TN2208
Ethernet, (LGATE)-Ethernet Multi-Function (MFB) boards.
The TN2208 LGATE MFB provides DEFINITY with the interface to Adjunct-Switch
Application Interface (ASAI) and Lucent adjuncts (for example, CONVERSANT®
Voice System). This circuit pack contains 12 ports for line circuit interface
(although only 8 are usable by the switch), each of which operates with 2
B-Channels and 1 D-Channel as specified in the Lucent ISDN-BRI Specification.
In this context, the term “ISDN-BRI port” is used to refer to ports on the TN2208
MFB circuit pack which are connected to ASAI or Lucent adjuncts. The TN2208
LGATE MFB is handled by the switch software as if it is an ISDN BRI compatible
