2. Error 2049:
■Test the Tone-Clock circuit p acks 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 wit h the following steps.
■If the system synchronization reference is a Tone-Clock
circuit pack and the master Tone-Clock circuit pac k fails
TDM Bus Clock Test #150, follow the steps listed in
“TDM-CLK” to replace the maste r Tone-Clock circuit pack.
■If the system synchronization reference is a DS1 interfac e
circuit pack and the master Tone-Clock circuit pac k fails
TDM Bus Clock Test #150, the primary or secondary (if
administered) synchronization referenc es 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 p rimary synchronization
reference is providing timi ng for the system or note (c) if the
secondary synchroniz ation reference is providing timing for
the system.
■If the slave Tone-Clock circuit pack fails the TDM Bus Cloc k
Test #150 but the master Tone-Clock does not fail this test,
the master Tone-Clock circuit pack mus t 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, rep lace the Tone-Clock circuit pack
in the slave port network. Follow the steps list ed in
“TDM-CLK” to replace the Tone-Clock circ uit pack.
h. Noise on the DS1 line can cause transient alarms on sync hronization.
Therefore, when a synchronization problem oc curs causing error typ es 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 p resented in the table belo w. By clearing
error codes associated with the
Test Synchronization Test,
for example, you may
also clear errors generated from oth er tests in the testing sequence.
