8-966 Issue 1 May 2002
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).
