System Modules
1-2 Overview
206 Module. Each 206 module has jacks to connect a maximum of two
outside lines and six extensions. (Extension jacks can connect phones or
other devices such as fax machines, answering machines, and modems.)
A system can have one or two 206 modules. With two 206 modules, you
can connect up to four outside lines and 12 extensions.
200 Module. This module is similar to the 206 module, without extension
jacks. It has two outside line jacks, which allow you to add lines when
you do not need more extensions. The system can have one 200 module
in combination with a 206 module. This combination provides up to four
outside lines and six extensions.
Module Connector. This connector is needed only if you have two
modules. It joins the modules so all lines and extensions are connected.
