Installing the Processor
Installing the processor includes the following procedures:
If both of the following conditions are true, follow the procedures in

NOTE:
If the system is programmed for Permanent Key mode, check the switch
setting. Refer to
detailed procedures. If the switch is set to Permanent Key-only operation,
all trunks revert to loop-start. If the switch is not set, any programmed
designation for ground-start trunks is retained.
The ground-start pool never has trunks assigned to it automatically, but
must be programmed after the ground-start ports are designated.
Ground-start trunks are assigned to the ground-start pool on initialization,
except in a system switched for Permanent Key mode operation. (In
Release 1.0, ground-start and loop-start trunks automatically defaulted to
loop-start.)
Beginning with Release 3.0, the feature module required for Release 2.1
and earlier is no longer needed. The Release 3.0 processor module
contains a PCMCIA memory card interface capable of accommodating a
4-MB memory card. This card is used to install or upgrade system
software and perform firmware upgrades on circuit modules. It can be
used to back up and restore system programming.
