TONE-BD (Tone-Clock Circuit Pack)
Issue 5 October 2002

555-233-119
The t/c selector circuit pack of interest is the one which was active at
the time the error was logged. This is the currently active t/c selector
unless there has been an SPE interchange for PPN problem, or an
EXP-INTF link switch for EPN problem, In order to determine
whether an interchange has occurred since the TONE-BD error,
examine the display initcauses log for SPE interchanges, and
EXP-LNK entries in the hardware error log for expansion link
interchanges.
If the t/c selector circuit pack was not replaced as part of the
previous step, replace it now.
4. If the error has not been corrected at this point, there is a problem
with the TDM Bus within the Port Network containing the reported
Tone-Clock circuit pack. This may include TDM Bus intercarrier
cables, Bus terminators, bent pins on the backplane, and errors on
any circuit pack plugged into the same Port Network. Refer to the
TDM-BUS section.
5. If the problem persists, follow normal escalation procedures.
l. Error Type 2561
This error indicates that a Tone-Clock circuit pack, with
a different circuit pack code as required for this system, has been inserted
in the port slot as shown in the Hardware Error Log. To resolve this error,
refer to the
‘‘How to Replace a Tone-Clock Circuit Pack’’
section for an
appropriate circuit pack code and replace the Tone-Clock circuit pack
according to the procedures indicated for this system. The meanings of the
aux data values are as follows:
1001
A TN756 Tone-Clock circuit pack is in the PPN of a one port
network system without High or Critical Reliability (Multicarrier
Cabinet).
1002
A TN756 Tone-Clock circuit pack is in the EPN of a one port
network system without High or Critical Reliability (Multicarrier
Cabinet).
1003
Either a TN741 or TN714 Tone-Clock circuit pack (instead of
a TN768, TN780 or TN2182) is in a one port network system
without High or Critical Reliability (Multicarrier Cabinet).
1004
Either a TN741 or TN714 Tone-Clock circuit pack (instead of
a TN768, TN780 or TN2182) is in a High or Critical Reliability
system.
1005
Same as for aux value 1004.
