4. Fibre Fed Remote Repeater 60-214701
Remote Repeater 60-214701 is built into a wall-mounted, environmentally protected (IP65) aluminium
alloy case; RF ports and connectors are also IP65 standard making the entire enclosure and
connecting ports weatherproof. Handles are provided for carrying the unit and the door is fitted with
locks and there are Power On and Alarm indicators on the outside of the door.
The Repeater has two fibre optic connections for two fibre optic cables, one carying Downlink signals
from the Tri-Band Cable Signal Combiner 60-214702 and one carying Uplink signals to the Tri-Band
Cable Signal Combiner 60-214702. The Repeater also had an RF connection carying Downlink and
Uplink signals to and from the Antenna facing the mobiles
Provision is made for feeding the PCS signal path out to an existing external PCS bi-directional
amplifier.
4.1. Remote Repeater 60-214701 Simplified Arrangement Sketch
60-214701 features dual redundant amplification stages in both Downlink and Uplink bands so that in
case of any single amplifier failure, complete signal loss would not occur in that path, allowing
continued coverage. It also has a comprehensive alarm system (each amplifier module carries its own
voltage-free contact alarm relay output), with the capability of remote configuration/alteration through
a multiplexed RS232 base station modem link. 60-214701 is powered from a DC supply at 24V which
is provided by PSU and Battery Backup 60-214703.
