Resetting The QRSS Error Register
To reset the QRSS error register and restart a test, type the following at the
command prompt:
AIRLINK PRO T1/E1> reset QRSS
NOTE The command RESET TEST does not reset the error count. The results of the last QRSS
test will remain on the QUERY PERFORMANCE screen until RESET QRSS is initiated.
Loopback Tests
The AirLink Pro T1/E1 Rack Mount provides the following loopback tests:
❚ Local Loop test
❚ Remote Loop test
NOTE You can initiate a loopback test for the local unit or the remote unit, but only one loopback
test can be active at a time.
Figure 4-6 shows a generalized view of the two loopback test types. Each of the
loopback tests and the conditions that apply during the test are described in
the following sections.
