Antenna Face 4 - Cabled for TDOA
WLS input cable connection thresholds:
Low: -109 dBm, High: -104 dBm
- Cable considered connected if min avg level is above low threshold OR
max avg level is above high threshold
- 4th sect delta column is the min avg level of the each port minus the
min avg level of the 4th sector port. This is useful when the 4th sector
is known to be unused, and can be used as a reference level to other ports.
Avg Signal Levels (dBm)

2 -111.2 -109.3 0.0
3 -111.1 -109.4 0.1

RF CABLING TEST RESULTS:
WLS Input Connected? Required?
1 YES YES
2 NO NO
3 NO NO
4 NO NO
5 YES YES
6 NO NO
7 NO NO
8 NO NO
Test Result: PASS
Press any key to continue.
The test software determines which WLS input ports are required to be connected based on the
WLS bpu.ini file. The test result will be PASS if all required WLS inputs are connected.
Otherwise the test result will be FAIL. Possible causes for a failure are also displayed.
2.10.9 WAN Port/Ping Test
The WAN Port/Ping Test is used to verify DS0 connection from the WLS to the GCS located at
the MSC. The test can also check for the presence of a WAN loop back, either via the CSU/DSU
in loop back mode or via a WLS WAN port loop back plug. Note: This test requires access to the
WLS unit through the front panel RS-232 serial port.
The WAN Port/Ping Test will try to ping the GCS. If this is successful then the PPP connection is
determined to be operational and the DS0 connection is operational. In addition, a loop back test
will be performed. An example of the test display is shown below.
Enter your choice: 9
WAN/PING TEST:
PING gcs (10.0.0.131): 56 data bytes
--- gcs ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 0/1/10 ms
Ping: Pass
The WAN Loopback Test can only be executed when
accessing the unit through the serial port.
Proceed with Test(y/n): n
Press any key to continue.
Failure of the WAN Port/Ping test indicates a lack of end-to-end connectivity between the WLS
and the GCS. Failure may indicate a fault in the CSU/DSU provisioning, a fault in the T1 DACS
