DS1-BD (DS1 Interface Circuit Pack)
Table 227. TEST #138 Loss of Signal Alarm Inquiry Test — Continued
Error Test
Code Result
FAIL DS1 Interface circuit pack detects a Loss of Signal alarm. The physical link is
broken or the remote DS1 endpoint is down. All trunks or ports of this DS1
interface circuit pack are out-of-service. If the DS1 Interface circuit pack is
designated as the supplier of the system synchronization source, then the
system synchronization maintenance will adopt a source elsewhere. Refer to
"SYNC (Synchronization)" section for details.
1300 FAIL The CSU Module or the T1 Sync Splitter is missing. The Near-End CSU Type
field on the add ds1 form has been administered as integrated but the 120A1
CSU Module/T1 Sync Splitter is not physically connected to the TN767E
board on the back of the port carrier.
1301 FAIL The 120A1 CSU Module or the T1 Sync Splitter is physically connected to the
TN767E board on the back of the port carrier but the Near-End CSU Type
field on the add ds1 form has not been administered as integrated.
1302 FAIL Attempting to use the 120A1 CSU Module with a TN767E circuit pack that is
configured for 32-channel (2.048 Mbps) operation. The CSU Module only
works with a DS1 board configured for 24-channel (1.544 Mbps) operation in
the United States of America.

Description/ Recommendation
1. If the DS1 Interface circuit pack connects to a T1 facility, call the vendor
of the T1 carrier to diagnose the remote DS1 endpoint. If the DS1
Interface circuit pack connects directly to a switch, call the system
technician of the remote switch to diagnose the DS1 endpoint.
2. Check the physical connection of the DS1 Interface circuit pack and the
cable. If a 120A1 CSU Module/T1 Sync Splitter is physically connected to
a TN767E board on the back of the port carrier, check the physical
connection of the CSU Module/T1 Sync Splitter and make sure the
Network Interface cable is plugged into the CSU Module's/T1 Sync
Splitter's NETWORK jack.
1. If using the 120A1 CSU Module/T1 Sync Splitter, plug the CSU
Module/T1 Sync Splitter into the TN767E circuit pack's connector on the
I/O connector panel on back of the carrier. Otherwise, change the
Near-End CSU Type field using the change ds1 form to other.
2. Run the test again.
1. If the 120A1 CSU Module/T1 Sync Splitter is to be used, use the change
ds1 command to change the Near-End CSU Type field to integrated.
Otherwise, physically remove the 120A1 CSU Module/T1 Sync Splitter
from the back of the port carrier.
2. Run the test again.
1. If the 120A1 CSU Module is to be used, physically remove the TN767E
circuit pack and reconfigure for 24-channel (1.544 Mbps) operation.
2. Reinsert the circuit pack and run the test again.
