AirLink Pro T1/E1 Rack Mount QRSS Test
Initiating the Test
The QRSS test is separate for each direction. This helps isolate unsymmetric
faults, such as RF interference versus antennae cable faults. The QRSS test can
be initiated by a command entered through the terminal user interface. You can
initiate a QRSS test from either end of the AirLink Pro T1/E1 Rack Mount link.
When the test is initiated, it is activated simultaneously from both ends of the
radio link. Each end of the link measures the received errors (independently)
and calculates the Bit Error Rate.
CAUTION This test interrupts the payload in the T1/E1 channel. Before initiating this test, you
should consider the impact of this test on the rest of the T1/E1 system.
To start a QRSS test on the local AirLink Pro T1/E1 Rack Mount, type the
following command at the AirLink Pro T1/E1 Rack Mount prompt:
AIRLINK PRO T1/E1> test qrss
The system prompts you to confirm the QRSS test:
AIRLINK PRO T1/E1> test qrss
WARNING: Start QRSS test? (Y/N)
