2. Error 2049:
■ Test the Tone-Clock circuit packs in the master and slave
port networks via the
test tone/clock PC long
command.
Check the Error Log for TDM-CLK errors and verify that TDM
Bus Clock Test #148 passes successfully. If Test #148 fails
with an Error Code 2 through 32, refer to “TDM-CLK” to
resolve the problem. If not, continue with the following steps.
■ If the system synchronization reference is a Tone-Clock
circuit pack and the master Tone-Clock circuit pack fails
TDM Bus Clock Test #150, follow the steps listed in
“TDM-CLK” to replace the master Tone-Clock circuit pack.
■ If the system synchronization reference is a DS1 interface
circuit pack and the master Tone-Clock circuit pack fails
TDM Bus Clock Test #150, the primary or secondary (if
administered) synchronization references are not providing
valid timing signals for the system. Check the system
synchronization references administered, and follow the
steps outlined in note (a) if the primary synchronization
reference is providing timing for the system or note (c) if the
secondary synchronization reference is providing timing for
the system.
■ If the slave Tone-Clock circuit pack fails the TDM Bus Clock
Test #150 but the master Tone-Clock
does not
fail this test,
the master Tone-Clock circuit pack must be replaced. Follow
the Tone-Clock replacement steps listed in the “TDM-CLK”.
If SLIP errors remain follow SLIP ANALYSIS.
3. Error 2305:
■ If the problem persists, replace the Tone-Clock circuit pack
in the slave port network. Follow the steps listed in
“TDM-CLK” to replace the Tone-Clock circuit pack.
h. Noise on the DS1 line can cause transient alarms on synchronization.
Therefore, when a synchronization problem occurs causing error types 1,
257, or 513, a WARNING alarm is first raised for 15 to 20 minutes before
the alarm is upgraded to a MAJOR or MINOR alarm.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the
Test Synchronization Test,
for example, you may
also clear errors generated from other tests in the testing sequence.
