2-7 Connecting External Alarms
The WAVEView OMC supports many alarms from the BTS. The external alarms are reflected at the OMC
operator station, and may be used for site alarms, such as open door, temperature and battery back-up
alarms. These customer defined alarms are sampled every two minutes by default and will report an
alarm when sent by the BTS alarm controller.
Using the details provided in these sections, make your connections for external alarm inputs.
The OMC operator can set the alarm text as described in the WAVEView OMC Setup and System
Administration Guide.
Identifying the Terminal Block
The alarms are processed on the alarm interface module located on the rear of the RF subrack
assembly. The alarm interface module has connections for incoming signals from external alarms and
the power supplies and an outgoing connection to the ICP processor card through a USB type cable.
The interfaces are shown in Figure 2-30.
This terminal block provides a plug connection for up to seventeen external alarms. The plugs, supplied
with the BTS, provide a closed loop for connection to a normally open alarm mechanism. The plug
If you are replacing an existing WAVEXpress system which has external
alarms connected directly to the processor card, you may connect your
existing RJ-45 alarm cable directly into the ICP processor card alarm
connector. Optionally, you can re-route your existing alarms to the
UltraWAVE alarm terminal block or add additional external alarms.
