XXX-BD (Common Port Circuit Pack/Media Module)
S8700 | 8710 / S8500 / S8300
Common Port Circuit Pack maintenance is a set of common tests used by every circuit pack or
media module listed in the following tables. The common portion of these circuit packs is the
generic hardware that interfaces with the TDM bus. The XXX-BD designation is also used on
SAT displays when reset board is entered with an empty circuit pack or media module slot,
or with a circuit pack or media module type that is in conflict with the actual board type
administered for that slot. Every circuit pack or media module suffix (B,C, D, and so forth) are
supported by “XXX-BD.”
When any of the Common Port circuit packs are physically removed from the backplane, no
alarm will be logged for approximately 11 minutes. In the case of the following, approximately 21
minutes will elapse before an alarm is logged:
● TN754 Digital Line,TN566 EMBEDDED AUDIX, and TN758 Pooled Modem circuit packs
for systems supporting circuit packs
● G700: MM712 Digital Line, MM720, and INTUITY AUDIX for systems supporting media
modules
When a circuit pack or media module that has been removed is alarmed, the alarm type is minor
and is classified as an on-board alarm. The time delay permits maintenance activity to be
performed without triggering an additional alarm.
Alarms are logged against only those common port circuit packs or media modules on which
ports have been administered. In a heavily loaded system, the interval between the removal of a
Common Port circuit pack or media module and the logging of the alarm may be several
minutes longer. The circuit packs in Table 904: XXX-BD Common Circuit Packs
on page 2540
contain ports on the TDM bus. Suffixes are not shown; for a list of every circuit pack supported,
see the table in Cicrcuit Packs in Maintenance Procedures (03-300192).
Those that appear in bold type are documented separately under their own MO name. The
circuit packs in Table 904: XXX-BD Common Circuit Packs
on page 2540 are listed by
apparatus code.
