System Overview

Line/Trunk and Extension Modules

The system supports 20 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 following table describes the line/trunk
extension modules in detail.
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. Letters can follow to
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 trunks.
An example of a module name is the 408 GS/LS MLX module. It provides four
line/trunk jacks and eight MLX extension jacks, and supports ground-start and
loop-start trunks
