Maintenance-Object Repair Procedures
A problem with an ISDN-LNK will affect every associated B channel since, without
it, no call-control information can be conveyed to the far-end switch or to a
terminal adapter. Stable calls may remain operational, but no new calls can be
placed. In turn, the ISDN-LNK depends on the:
TN464C/D UDS1 Interface circuit pack where it resides
packet bus that provides the link to the processor
If there are problems with the ISDN-LNK, also investigate the TN464C/D UDS1
Interface circuit pack (UDS1-BD) and the packet bus (PKT-BUS).

1. Run the short test sequence first. If every test passes, run the long test sequence. Refer to each appropriate
test's description, and follow its recommended procedures.
2. pp is 24 for 24-channel interfaces and 16 for 32-channel interfaces.
Notes:
a. The D channel is demand busied out. No calls can be made over this
D channel.
b. This Error Type indicates that the circuit pack has been removed or has
been insane for more than 11 minutes. To clear the error, reinsert or
replace the circuit pack.
