DS1-BD (DS1 Interface Circuit Pack)
Issue 4 May 2002 10-633 555-233-123
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.
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.
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.
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.
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.
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.
