Accessing Adjunct Ports Using
ss/pp for TDL Modules
9
The slot/port number displays sspp to distinguish the 2-digit slot number from 
the 2-digit port number. Slot is the slot number in the carrier and port is the port 
number on the module. 
New Troubleshooting Scenario 9
The following is an additional troubleshooting scenario that has occurred, along 
with its possible solution
As with MLX modules, the slot/port numbering for adjunct ports on 
412 LS-ID-TDL modules begins at 21. The slot/port numbering for 
adjunct ports on a 024-TDL module begins at 25. For example, on a 
412 LS-ID-TDL module in slot 1 of the carrier, to access adjunct port 
710, you enter 0121 as the slot/port number (01 indicates slot 1 on 
the carrier). On a 024-TDL module in slot 1 of the carrier, to access 
adjunct port 710, you enter 0125.
Table 9-1.  Troubleshooting Scenario
Problem Possible Cause  Solution 
Internal loopback test 
(ILP) fails even though 
the line/trunks are 
functioning properly.
The ILP will fail if Music-
On-Hold is assigned to 
any line/trunk ports on the 
module you are testing.
Remove Music-On-
Hold assignment 
before conducting 
the test.
