Section 3.24.5
Performing a Loopback Test
Loopback tests are a useful means of testing the T1/E1 hardware on the device and the T1/E1 connection with
remote devices. Three types of tests are available:
• Digital Loopback – ROX II digitally sends frames and immediately returns them to the device. This test is used
to isolate problems within the T1/E1 circuit.
• Remote Loopback – ROX II transmits frames to the Tx port and compares them with frames received on the Rx
port. A loopback plug or cable must be installed on the T1/E1 port. This test is used to isolate problems within
the WAN module.
• Line Loopback – ROX II transmits frames across the T1/E1 line to a remote Channel Service Unit/Data Service
Unit (CSU/DSU). This test determines if a problem exists outside the device.
Regardless of the loopback type, a loopback test is successful if the frames received match those that were sent.
Missing frames and frames that contain discrepancies indicate a potential problem in the T1/E1 hardware or line.
To perform a loopback test on a WAN interface, do the following:
IMPORTANT!
Performing a loopback test on an active interface will immediately cause it to go down. However, the
trunk will be automatically initialized after the test is complete.
1. Make sure a WAN interface has been configured. For more information, refer to
