EPEATER FEATURES
3.3.1 Controller
The integrated Controller Module (Control Box) has three main functions:
1. Detects faults in the repeater and issues an alarm indication.
2. Controls the active components in the Repeater and enables the

Two modes of monitoring and control are available:
External PC - through the serial interface connector in the Control Box.

•
Remote control - via a modem connected to the Control Box serial interface.
A standard or cellular modem can be installed inside the Repeater enclosure,

The Repeater’s Alarm, Control and Monitor functions are performed by Dekolink’s
RMT software. For more information, see the RMT User's Guide.
The Controller transmits in two modes: Polling and Burst. When operating in Burst
Alarm mode, the Controller generates a burst alarm and reports the faults to the local
or remote connection. The Controller software handles the alarm reporting and
parameters transmission to the Repeater’s outside world.

3.4.1 SALC Description
The Smart Automatic Level Control (Smart-ALC) is an innovative solution for
automatic repeater gain adjustment. Combined with advanced control algorithms,
SALC can perform gradual learning of traffic load characteristics and adjust the
Repeater RF Gain to an optimal value.
Some of the SALC advantages are:
Network friendly: The SALC periodically learns traffic conditions and set the gain
so that at maximal traffic the repeater output is at maximal value. In all other cases
the gain is constant and the output power follows the BTS fluctuations. This feature
introduces system transparency – the mobile using the repeater is not affected by
repeater existence. Repeaters that blindly amplify the pilot code (minimal
