Receive signal level must be between
0 and 4.8 volts. A signal level closer to
4 volts indicates a more robust system.
Connect Voltmeter to orange (RSSI)
and black (GND) test jacks.
Check the BER performance of the hop.

1) Loopback the T1 (or E1) data at the far end.
2) Using a T1 (or E1) test set, send data to the far end and monitor
the BER. There should be no errors over a 15-minute period.
