TIE-DS1 (DS1 Tie Trunk)
Issue 1 June 2005 2289
FAIL The far-end trunk did not respond to the seizure of the near-end trunk
within the allowable time period. This test could have associated in-line
errors in the error log.
1. Enter list configuration board location. If the circuit pack
is a TN767B vintage 8 or 9, a failure of test 136 causes a subsequent
failure of test 7 due to a firmware bug. Eventually, the board and all of
its ports are taken out of service, and extraneous on-board alarms are
generated. Replace the circuit pack with a TN767C V3 or later.
2. Verify that the Trunk Type field on the Trunk Group administration
form matches the trunk type administered on far-end switch.
3. Look for DS1-BD, UDS1-BD, or MG-DS1 errors in the hardware error
log. If present, see DS1-BD (DS1 Interface Circuit Pack)
on page 978,
UDS1-BD (UDS1 Interface Circuit Pack)
on page 2374, or MG-DS1
(DS1 Interface Media Module) on page 1594 maintenance
documentation.
4. Retry the test at 1-minute intervals up to 5 times.
2000 FAIL Response to the seizure message was not received within the allowable
time period.
1. Enter list configuration board location.
For circuit packs: If the circuit pack is a TN767B vintage 8 or 9, a
failure of test 136 causes a subsequent failure of test 7 due to a
firmware bug. Eventually, the board and all of its ports are taken out of
service, and extraneous on-board alarms are generated. Replace the
circuit pack with a TN767C V3 or later.
G700: Replace the Media Module.
2. Verify that the Trunk Type field on the Trunk Group administration
form matches the trunk type administered on far-end switch.
3. Look for DS1-BD, UDS1-BD, or MG-DS1 errors in the hardware error
log. If present, see the DS1-BD (DS1 Interface Circuit Pack)
on
page 978, UDS1-BD (UDS1 Interface Circuit Pack)
on page 2374, or
MG-DCP (Digital Line Media Module)
on page 1593 maintenance
documentation.
4. Retry the test at 1-minute intervals up to 5 times.
PASS The trunk can be seized for an outgoing call.
