Merlin System Components; The Model 1030 Control Unit And Expansion Unit - AT&T MERLIN 3070 Administration Manual

MERLIN System Components

When performing your administration tasks, you work with three components of the MERLIN system: the control unit,
the administrator/attendant console, and individual voice terminals. You may also have some optional equipment that
adds teatures and capabilities to your system but does not affect system administration. The following descriptions will
help you become familiar with the components that make up your system.
For information about system installation, refer to the /nstallation Guide: /Mode/s 1030 and 3070.

THE MODEL 1030 CONTROL UNIT AND EXPANSION UNIT

The Model 1030 control unit provides connections for up to 10 outside lines and 30 voice terminals, or for up to 15 out-
side lines and 20 voice terminals, depending on the combination of Line and Voice Terminal Modules you choose. For
a 1030 configuration, you have Line Modules in slots 7 and 8 (10 lines) and Voice Terminal Modules in slots 9, 10, and
11 (30 voice terminals). For a 1520 configuration, you replace the Voice Terminal Module in slot 11 with a Line Module.
This increases the number of lines to 15 and decreases the number of voice terminals to 20.
The addition of an Expansion Unit makes the Model 1030 control unit a Model 3070 control unit and increases system
capacity to as many as 30 outside lines and 70 voice terminals, again depending on the combination of Line and Voice
Terminal Modules you choose. Similarly, a 1520 configuration can be changed to a 3070 configuration by replacing the
Line Module in slot 11 with a Voice Terminal Module and adding an Expansion Unit.
