EX7100 Repeater Configuration
8.1 General
The EX7100 can be configured as a full duplex repeater to enable the link to operate over
a much greater distance and over difficult terrain. In repeater configuration, the EX7100
retains the extensive remote monitoring and diagnostics via the system’s internal
engineering channel.

retains the extensive remote monitoring and diagnostics via the system’s internal
engineering channel.
An EX7100 repeater is made up of two 64kbps Data terminals linked back-to-back at the
G.703 level. Any EX7100 terminal may be configured for use as a repeater from its front
panel, enabling a user to redeploy existing link terminals as required.

8.2 Installation
Installation of an EX7100 repeater will follow similar instructions to installing any other
EX7100 terminal. Terminals need to be mounted in close proximity to one another enable
necessary interconnecting cables to be as short as possible.

As the typical location of a repeater site tends to be lightning prone, extra care should be
taken to ensure that all terminal grounding and lightning protection systems are well
engineered.

Terminal Interconnections
To enable retransmission of both user and engineering traffic through the repeater there
are basic connections that need to be made between the two terminals.

Interconnect
The G.703 output port of each terminal must be connected to the G.703 input port of the
other terminal. This is best done using the 75 Ohm G.703 connections on the rear panel.
