Identifying Line And Station Modules - AT&T Merlin II Feature Module 2 Data Communications Manual

Identifying Line and Station Modules

TYPES OF MODULES
During this first phase of planning you'll be deciding how you want voice
and data components connected to jacks on the MERLIN II system control
unit and recording your decisions on the. Master Planning Form.
The jacks on the control unit modules provide points of connection for the
system's outside lines and stations.
The system's outside telephone lines connect to line jacks, as do
loudspeaker paging equipment and the music source for Music-on-Hold,
if your system has these options.
Data devices, voice terminals, and basic telephones connect to station
jacks.
The first step in planning your system is to decide what line and station
modules will appear in each slot in your control unit. The various types of
modules are described below and shown in Figure 2-2. An explanation of
how the MERLIN II system assigns numbers to lines and station jacks on
modules is found under "Automatic Numbering of Jacks on Line and Station
Modules. "
The 4-Line/8-Analog Voice Terminal (408) Module has four line jacks near
the top of the module and eight station jacks on the bottom portion of the
module.
The 8-Analog Voice Terminal (008) Module has eight station jacks at the
bottom.
The 4-Line with Touch-Tone Receivers (400 w/HTR) and &Line (800)
modules have line jacks on their top portions.
The 12-Basic Telephone (012) Module has 12 station jacks— four at the
top and eight at the bottom.
The digital Station (O08D) Module has four station jacks at the top and
four near the bottom.
There is a power failure jack for every four outside line jacks on a module.
