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:
m. Error Type 3329
The system attempted but failed to interchange
Tone-Clock circuit packs. (This error occurs only in Port Networks with
duplicated Tone-Clocks.) The fault may lie in the standby Tone-Clock or in
the circuit pack that controls selection of the active Tone-Clock (the
t/c
selector
). The goal of the following procedure is to ensure that both
Tone-Clocks can be interchanged into while either t/c-selector circuit pack
is active.
1. Examine the Error Log for errors reported against circuit packs in
the same Port Network, paying special attention to TDM-CLK,
TONE-BD, DUPINT, SW-CTL, and EXP-INTF. Follow the procedures
indicated for any such errors found. After eliminating the above
potential problem sources, proceed with the following steps.
2. Determine which circuit pack was controlling the choice of
Tone-Clock at the time the error occurred.
■ For a PPN, the t/c selector is the DUPINT circuit pack on the
A-carrier.
■ For an EPN, the t/c selector is the active EXP-INTF circuit
pack that is connected to the PPN. This is EXP-INTF 2A01 or
2B02 for EPN1 and 3A01 or 3B02 for EPN2.
The t/c-selector circuit pack of interest is the one which was active
at the time the error was logged. An EXP-LNK interchange since
the time of the error may have made that circuit pack the current
standby. Determine whether an interchange affecting the t/c
selector has occurred since the TONE-BD error. When investigation
an EPN Tone-Clock, look for EXP-LNK entries in the hardware error
log for PNC interchanges, which would affect the EXP-INTF.
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.
