Adding the WMTS to the NMS
Once you have the WMTS permanent IP address, you should add the WMTS to the
NMS. Refer to the NMS User Guide for instructions.
Provisioning the Monitoring Modems
The procedure for provisioning a monitoring modem is identical to any other modem
provisioning. Refer to the NMS User Guide for instructions. The MAC address of each
monitoring modem appears on a sticker attached to the modem, visible from the rear of
the Base Station rack.
Follow these guidelines:
 It is recommended to select a name for the monitoring modem that will indicate its
functionality (e.g., Monitoring modem sector A).
 The monitoring modem configuration file should be set to a single best effort
service, and must not include any QoS features such as priority or CIR.
Verifying Proper BSR Operation
The initial tests for verifying proper operations are performed using the Monitoring Modems.
The tests verify proper operation of the base station rack, even before connection to the
CPE modems. The MMUs monitor the three channels covered by the BTS. Each MMU
monitors a single channel. MMU1 is connected to channel 1, and so on.
For each of the three channels, check the following parameters through the NMS. Verify
that the actual values are within the expected values.
 Check the modem Downstream Received Power and SNR (refer to the NMS User
Guide for instructions).
 Check the MMU Transmit Output Power (refer to the NMS User Guide for
instructions).
 Check the channel Upstream Received SNR (refer to the NMS User Guide for
instructions).
Parameter Expected Value
Downstream Received Power - 16 ± 3 dBmV
Downstream SNR ≥ 30 dB
MMU Output Power 62 ± 4 dBmV
Upstream Received SNR ≥ 22 dB
