UDS1-BD (UDS1 Interface Circuit Pack)
Table 530. TEST #138 Loss of Signal Alarm Inquiry Test — Continued
Error Test
Code Result
FAIL UDS1 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
UDS1 interface circuit pack are out-of-service. If the UDS1 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 the
the UDS1 connects to a T1 network facility:
If the UDS1 connects to a line-side terminating device such as a PRI terminal
adapter:

Description/ Recommendation
''SYNC (Synchronization)''
1. Check the physical connection of the UDS1 Interface circuit pack and the
cable. If a CSU Module or a Sync Splitter is physically connected to a
UDS1-BD board on the back of the port carrier, check the physical
connection of the CSU Module/Sync Splitter and make sure the Network
Interface cable is plugged into the CSU Module's/Sync Splitter's
NETWORK jack.
2. If the UDS1 Interface circuit pack connects to a T1 facility, call the vendor
of the T1 carrier to diagnose the remote DS1 endpoint. If the UDS1
Interface circuit pack connects directly to a switch, call the system
technician of the remote switch to diagnose the DS1 endpoint.
1. Check the physical connection of the UDS1 Interface circuit pack to the
terminating device. Check premise distribution system (or intra-premise
wiring) for physical connection failures. If a CSU Module or Sync Splitter
is physically connected to a UDS1-BD board on the back of the port
carrier, check the physical connection of the CSU Module/Sync Splitter
and make sure the Network Interface cable is plugged into the CSU
Module's/Sync Splitter's NETWORK jack.
2. Contact the vendor of the line-side terminating device to diagnose the
equipment.
