1. 616 System Overview
The Protegé 616 is the newest addition to the Protegé
key system family. It supports the 26 Button Business
with Display and the 17 Button Business without
Display digital keysets. It also works with an analog
adapter that provides support for single-line tele-
phones and other analog devices like fax machines
and modems.
Protegé 616 comes ready-to-use with a default
software configuration. The software can be
customized to meet customer requirements from the
Business with Display keyset.
1.2 616 Capacity
The 616 comes equipped with three lines and eight
digital extension ports. The system can be expanded
to a maximum capacity of 6 lines and 16 digital
extensions by installation of an optional 3x8 expan-
sion board. Each digital extension port can be modi-
fied with the use of an Analog Adapter to provide
two analog ports. The maximum number of analog
extension ports possible is 30.
2. Hardware Summary
A single self-enclosed cabinet houses most of the 616
system components. See Figure 1-1. The cabinet can
be mounted on a wall. The cabinet comes fully
equipped to support many small business applica-
tions such as external paging, music on hold, power
failure transfer and voice mail integration.
