4.2.4. Voltage Standing Wave Ratio (VSWR)

This feature enables the provider to query the status of the antenna system (antenna
and cable). The voltage standing wave ratio of the DL output antenna port is
measured.
If the VSWR falls below the value set in the "Alarming Management" of the software,
an alarm is released. The alarm can be forwarded to the OMC where the faults and
irregularities can be acknowledged and eliminated promptly.
The current VSWR value can be checked in the "Status and Reports" menu
accessible via the home page of the web interface.

4.2.5. Status Information

The Status and Reports menu, which is accessible via the home page of the web
interface, provides information about the current gain, isolation, output level and
receive signal strength indication (RSSI) values.
The RSSI provides controlling and monitoring of the receive level of a Node B (DL
RSSI) or user equipment (UL RSSI) to a Node G. 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. A corresponding measurement is
also made for the output levels. The module can detect RSSI and output levels per
time slot.

4.2.6. Alarm forwarding

Alarms can be forwarded to a defined phone number or to the OMC if the Node G is
equipped with a modem or a mobile station. This enables the provider to control and
to query the status of the network. Faults and irregularities can be recognized and
eliminated.
With an optional modem the Node G 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.
