2. From another telephone, dial the directory number that maps to the
registered WTN.
If the portable telephone rings, it is functioning properly.
If the portable telephone does not ring, check the Meridian 1
programming to ensure that the WTN has the proper directory number
assignment.
To conduct a signal strength test establish a connection with a radio, first
ensure that you get a connection with the same radio. To do so, use Directed
RSSI and measure the Receive Signal Strength Indicator (RSSI) level (see the
user guide for the portable telephone for instructions on connecting to the
radio). Replace any portable telephone whose reading is significantly different
from the others.
Note: An RSSI value of -35 dBm is the strongest (best) possible signal
strength. As the signal fades, the absolute value of the RSSI number
increases. The link drops as the value approaches -100 dBm.
Optional checks
If Transfer on Radio Loss has been programmed, verify that it is operating
properly:
1. From another telephone, make a call to the portable telephone.
2. Remove the batteries and wait 10 seconds for the link to drop.
After the 10 seconds of silence, the calling telephone should hear ringback and
the destination phone should ring, indicating the call has been transferred.
If the portable telephone does not appear to be operating correctly, see
Table 40: Troubleshooting portable telephones, on page 172.
