Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the
Primary Signaling Link Hardware Check
, for
example, you may also clear errors generated from other tests in the testing
sequence.
Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Link Port itself depends on the health of the DS1/UDS1
Interface circuit pack on which it resides. This test will fail if there are problems
with either the ISDN-PRI Primary D-channel port or the DS1/UDS1 circuit pack.
The ISDN-PRI Primary D-channel also depends on the health of either the
Processor Interface Link or the Processor Control circuit pack providing
connectivity to the DS1/UDS1 circuit pack.
If there are problems with the ISDN-PRI Signaling Link, also investigate the
DS1/UDS1 circuit pack (DS1-BD/UDS1-BD) and the Processor Interface Link or
Packet Control (PI-LINK/PACCON) dependent upon which is used
