with their own power supplies and do not rely on the system.) Each carrier
requires its own power supply module, installed in the carrier's leftmost slot. The
current power supply module is the 391C1; it works with all releases of the
system.

Line/Trunk and Extension Modules
Line/trunk and extension modules have jacks for connecting telephone company
lines/trunks and extension wires to the control unit. The system supports 17 types
of line/trunk and extension modules. For maximum flexibility, some modules
support only lines/trunks, some only extensions, and some a combination of the
two.
