Transmit Power Control
The Transmit Power Control (TPC) function, provides the capability of defining the
transmit power in order to comply with the ETSI standard requirement of
30 dB maximum. See Table 4-1 for full details of transmit power control.
Alarm Connector
The IDU-C has two external alarm inputs in the form of dry-contact relays. The
Alarm interface is located on the front panel of the IDU-C and is a 9-pin D-type
female connector. The user enables or disables each of the alarms and can
configure the text that appears in the alarm trap. The ODU sends the alarm within
less than a second from actual alarm trigger.
The alarm connector is available as an ordering option for the IDU-E.
Optional External Antenna
FA4800 supports configuration of an external antenna. In this configuration, the
outdoor unit is supplied with an N-type connector that connects through a coax
cable to the external antenna.
An external antenna can extend the range of the link, and in some cases, may help
to reduce environmental interferences. Various external antennas are available for
the FA4800 operating frequencies.
For example, an optional flat panel 28 dBi external antenna increases the
operation range of FA4800 up to 80 km (50 miles).
