2.1 Control Unit Specification
The control unit is comprised of 3 printed circuit boards (PCBs) housed within a 3-part plastic
enclosure. The enclosure consists of an access cover, a top cover and a base. Six slots in the
top cover allow line, extension and feature modules to be added. The access cover encloses
the connection area on which the wiring is terminated.

The basic control unit is equipped for 16 extensions - 8 digital and 8 analogue. The capacity of
the system can be expanded up to 48 extensions by the addition of extension modules into the
2 extension slots. There are no line interfaces on the basic control unit - these are also added
by inserting the PSTN/ISDN line modules into the two line slots. See below for card and
capacity details.
The control unit also provides for the connection of an applications module (with 2 channel 4hr
voice mail) and a broadband router module that can be configured to operate as an Ethernet to
Ethernet router or as a 2-wire ADSL modem.
The sliding plate is used to allow access to the 6 slots on the main control board when
connecting the plug-in modules. It also functions to lock into position the plug-in modules once
they have been inserted.
