3. If error 2305 or 3848 persists, all cloc k signals from the indicated
board were lost. If the reported Tone-Clock circuit pack is in a Port
Network with duplicated Tone-Clocks, the problem may lie with the
circuit pack responsible for selecting the active Tone-Clock circuit
pack (the
t/c selector
).
For a PPN, the t/c selector is the DUPINT circuit pack on
carrier A.
For an EPN , the t /c s elec tor is the a ctiv e EXP-INTF c irc uit
pack that is connec ted to the PPN. This is EXP-INTF 2A0 1 or
2B02 for EPN1 and 3A01 or 3B02 for EPN2.
The t/c selector circuit p ack of interest is the one which was ac tive
at the time the error was logged. This is the c urrently 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 interchang e has occurred sinc e the
TONE-BD error, examine the display initcauses log for SPE
interc han ges, and EXP- LNK en tries in the hard ware e rror l og fo r
expansion link interchanges.
If the t/c selector circ uit pack was not replac ed as part of the
previous step, replac e 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 repor ted
Tone-Clock circuit pack. This may includ e TDM Bus intercarrier
cables, Bus terminators, b ent pins on the backp lane, and errors on
any circuit pack plugged in to the same Port Network. Refer to the
TDM-BU S sect ion.
5. If the problem persists, follow nor mal escalation proced ures.
l. Error Type 2561 This error indicates that a Tone-Clock circuit pac k, with
a different circuit pac k 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 circ uit pack cod e and replace the Tone-Clock circ uit pack
according to the procedures indic ated for this system. The meanings of
the aux data values are as follows:
