5.2.5. RSSI (Receive Signal Strength Indication)
The RSSI provides controlling and monitoring of the receive level of a base station
(DL RSSI) or user equipment (UL RSSI) to a Node M/C. It measures the level of the
input signal by detecting the RF and converting the analogue level into a digital
value. The data are processed and evaluated by software. An alarm will be released
if the measured signal level exceeds the alarm level set by the provider via software.
) Note: If the Node M/C is equipped with a diversity path, both values will be
combined before the RSSI evaluation. Thus, only one UL value is
reported.
The current RSSI values can be checked in the “Status and Reports” menu
accessible via the home page of the web interface.
5.2.6. Alarm Forwarding
Alarms can be forwarded to a defined phone number or to the OMC if the Node M/C
is equipped with a modem or a mobile station. This enables the provider to control
and to query the status of the network via pocket switched or circuit switched
connection. Faults and irregularities can be recognized and eliminated.
With an optional modem the Node M/C also provides an SMS feature, by which the
unit is able to send out alarm messages as SMS. For further details please contact
your supplier.
