j. Error Type 2049:
S8700-series Fiber-PNC
TDM-CLK (TDM Bus Clock)
The Tone-Clock circuit in the master port network was unable to detect the incoming
synchronization signal, but the other tone-clock was able to detect the references. If the
Aux Data is 0, the problem is with the signal on the primary. If the Aux Data is 1, the
problem is with the signal on the secondary. The system should switch clocks in this
situation.
1. If this error is against PN 1’s clock board and the system is using a Stratum-3 clock,
check the cabling that brings the Stratum-3 signal to this clock board.
2. Replace the current standby IPSI or Tone-Clock circuit pack. See Replacing the IPSI
or Tone-Clock Circuit Pack.
k. Error Type 2305:
S8700-series Fiber-PNC
The indicated Tone-Clock circuit is an active slave Tone-Clock that has detected a loss of
timing signal from its EXP-INTF synchronization source. (A slave Tone-Clock resides in a
PN that does not contain the system’s reference synchronization source.)
1. Enter display errors and display alarms, and follow the repair procedures for
EXP-INTF (Expansion Interface Circuit Pack), TDM-CLK (TDM Bus Clock), and
TONE-BD (Tone-Clock Circuit Pack) error log entries that have on-board alarms.
2. If the 2305 errors persist, follow the repair procedures for EXP-INTF (Expansion
Interface Circuit Pack) error log entries 257, 769, or 770, or any errors logged against
SNI-BD (SNI Circuit Pack), SNC-BD (Switch Node Clock Circuit Pack), or FIBER-LK
(Fiber Link).
3. If the 2305 errors persist:
a. For Port Networks with more than one Tone-Clock circuit, execute test
synchronization r 10 to see if new 2305 errors against TDM-CLK were
reported. If not, execute reset pnc interchange and test
synchronization r 10 again, and recheck for new 2305 errors against
TDM-CLK
b. For Port Networks with a single Tone-Clock circuit, execute test
synchronization r 10 to see if new 2305 errors were reported.
If no new instances of the 2305 errors were logged for either test, enter test
tone-clock location long clear to clear the TDM-CLK errors. The procedure
is complete.
4. For Port Networks with more than one Tone-Clock circuit:
a. Enter set tone-clock location to interchange the Tone-Clocks.
