4.4.6.4 Time Zone Offset From UTC
This is the offset of the local time from UTC (Coordinated Universal Time).
The range is from -12:00 up to +13:00 in 30 minutes resolution. The format must
be either -XX:YY or +XX:YY where YY is either 00 or 30.
The default is +02:00.
4.4.6.5 Stop Tx After Hold Over Timeout
Upon losing the 1PPS clock from the GPS, or if the received clock is not considered
accurate enough because the number of received satellites dropped below the
minimum (four satellites), the local 1PPS clock will be generated using the
available 16 MHz clock. After a certain time (defined by the Hold Over Passed
Timeout parameters described below), it is assumed that due to clock drifts there
might be interferences among sectors belonging to the Base Sectors and sectors
belonging to neighboring Base Stations). If the Stop Tx After Hold Over Timeout
parameter is set to Enable, the Base Station will stop transmitting after this
timeout, to prevent interferences to the sectors belonging to other Base Stations. If
it is set to Disable, transmissions will continue indefinitely, at the expense of
potential interferences to sectors belonging to other Base Stations.
The default is Disable (Hold Over indefinitely).
4.4.6.6 Hold Over Passed Timeout (Min)
This parameter defines the Hold Over timeout, after which there might be
interferences to other sectors. When the Stop Tx After Hold Over Timeout is
enabled, transmissions will stop after this timeout. When the Stop Tx After Hold
Over Timeout is disabled, this timeout is used to generate a trap indicating that
there might be interferences to neighboring sectors.
The range is from 0 to 2880 (minutes).
The default is 30 (minutes).
4.4.7 GPS Info
The GPS Info menu displays read-only information received from the GPS receiver
(when available). The displayed details include:
Number Of Received Satellites: The number of satellites received by the GPS
receiver. For proper operation at least four satellites should be received.
Longitude: The longitude as calculated by the GPS receiver. The format is
<xx Deg yy.yyy Min, A>, where xx is the longitude in degrees, yy.yyy is in
