8-2 Software maintenance and diagnostics
For maintenance purposes, each circuit on the IPE is identified by a circuit
number that depends on the card type and a line subgroup number in the range
0 through 15. This corresponds to the line card slot on the IPE shelf where the
circuit resides.
IPE maintenance state indicators on the MAP display are essentially the same
as those defined for other SL-100 peripherals (see the following table).

Description
PMs are automatically removed from
service by system maintenance.
PMs are manually removed from service
by command BSY to allow testing and
other manual maintenance action.
PMs are not acted upon by system
maintenance and must be returned to
service manually.
PMs connected to the network are
unable to communicate with CC because
the network or the links used to carry
messages between the PM and the
P-side of the network are unavailable.
PMs are still in service but flagged by
system maintenance because of one of
the following situations:
• a minor error condition occurred
• the PM failed a minor audit test
• the load is not listed in the
corresponding data table
Call processing service is not affected.
PMs are in service and available to
support any intended process.
