Line/Trunk and Extension Modules 2
The line/trunk and extension modules inserted into the control unit have jacks for
connecting CO trunks and system telephone wires to the control unit.
A system with a basic carrier has five slots for modules. Up to two expansion
carriers can be added, each one providing six slots for modules.
The system supports 17 different types of modules that vary in the types of
lines/trunks that they support and the types of telephones or other equipment that
can be connected to them.
The names of the modules identify their capacities and capabilities. The first digit
tells you the number of line/trunk jacks a module supports, while the last two digits
describe the number of extension jacks it supports. Following the number may be
letters that indicate the type of trunk it supports, that is,
LS
for
loop-start
and
GS
for
ground-start
; if the number indicates line/trunk support and no letters follow,
the module supports loop-start trunks. For example, the 408 GS/LS MLX module
provides four line/trunk jacks and eight MLX extension jacks, and supports
ground-start and loop-start trunks (see Figure 2–8
).
