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 ack and the
cable. If a 120A1 CSU Module is physically connected to a TN464F board
on the back of the port carrier, check the physic al connection of the CSU
Module and make sure the Network Interface cable is plugged into the
CSU Module’s NETWORK jack.
2. If the UDS1 Interface circuit pack c onnects 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 120A1 CSU Module is
physically connected to a TN464F board on the back of the port carrier,
check the physical connection of the CSU Module and make sure the
Network Interface cab le is plugge d into the CSU Module’s NETWORK jack.
2. Contact the vendor of the line-side terminating device to diag nose the
equipment.
1300 FAIL The CSU Module is missing. The
Near-End CSU Type field on the add ds1 form
has been administered as
integrated but the 120A1 CSU Module is not
physically connected to the TN464F board on the back of the port carrier.
1. If using the 120A1 CSU Module, plug the CSU Module into the TN464F
circuit pack’s connector on the I/O connec tor 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.
