9-937ISDN-LNK (ISDN-PRI Signaling Link Port)
9
A problem with the ISDN-LNK will have an effect on all of the associated
B-channels since without it no call control information can be conveyed to the
far-end switch or terminal adapter. Stable calls may remain operational, but no
new calls can be made. The ISDN-LNK in turn depends on the TN464C/D UDS1
Interface circuit pack it resides on and the packet bus which 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).
