See the preceding sectio n, ‘‘How to Replace a Tone-Clock Circuit Pack’’. If
replacement does not solve the p roblem, follow normal escalati on
procedures.
f. Error Type 257Τhis error indicates transient commun ication problems
with this circuit pac k . This error is not service-affecting and no action is
required.
g. Error Type 513This circuit pack has an on-board hard ware failure.
Replace the circuit p ack using the proc edure describ ed in preced ing
section, ‘‘How to Replace a Tone-Clock Circuit Pack’’.
h. Error Type 769This error can be ignored, b ut look for other errors on this
circuit pack.
i. Error Type 1025This error is not service-affecting and no action is
required.
j. Error Type 1538The circuit pack was taken out of service b ecause of an
excessive rate of uplink messag es. Use test tone-clock PC long to reset
the circuit pac k and put it bac k into service. If the command is not
successful, replac e the circuit pac k using the proced ure described in the
preceding se c tion, ‘‘How to Replace a Tone-Clock Circuit Pack’’. If the
alarmed circuit p ack is the active Tone-Clock of a duplic ated pair, first
interchange Tone-Clocks via the set tone-clock PC command to avoid a
service outage. If the error occ urs again within 15 minutes, follow normal
escalation procedures.
k. Error Type 2049 or 2305These errors indicate the loss of one or more
clock signals from the repo rted Tone-Clock circuit pac k, which was active
at the time of the error. The effect of any of these errors is described in the
table for error type 1. Diagnosis of the p roblem is the same for all four error
types, with the exception noted below.
1. Examine the Hardware Error Log for errors reported against c ircuit
packs in the same Port Network, espec ially TDM-CLK, TONE-BD,
DUPINT, SW-CTL, and EXP- INTF. Fo llow t he rep air o r rep lac ement
procedures indic ated for any such errors found .
2. If the error is not corrected b y resolving errors found in step 1, the
Tone-Clock circuit pack should be replaced. See the p receding
section, ‘‘How to Replace a Tone-Clock Circuit Pack’’.
NOTE:
Replacing the circ uit pack and retesting it with the test
tone-clock command is not adeq uate to retire this alarm and
return the Tone-Clock Circuit Pack to full service; the Clock
Health Inquiry test (#46) will conti nue to fail. Because the
ability to generate cloc ks was considered lost, once any
repairs have been made it i s necessary to execute the set
tone-clock PC override comman d, forci n g t he circu i t pack to
become active. If the p roblem has not actually b een
corrected, this ac tion may cause a disruptio n in service for
active digital fac ilities users.
