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 pac k is
designated as the supplier of the system synchronization source, then the
system synchronization maintenance will adopt a source elsewhere. Refer to
the ‘‘SYNC (Synchronization)’ section in this chapter for details. If the UDS1
connects to a T1 network facility:
1. Check the physical connection of the UDS1 Interface circuit p a c k and the
cable. If a CSU Module or a Sync Splitter is physically connected to a
TN464F 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 plugg ed into the CSU Module’s/Sync Splitter’s NETWO RK
jack.
2. If the UDS1 Interface circuit pack connec ts to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the UDS1 Interface
circuit pack connects d irectly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
If the UDS1 connects to a line-side terminating device such as a PRI terminal
adapter:
1. Check the physical connection of the UDS1 Interface circuit p ack 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 TN464F 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.
