CONFIGURING LOOPBACKS
Loopbacks provide a way to test the data communication path between the
Campus unit, the remote unit, and the remote host equipment. The
Campus-REX supports two types of loopbacks:
• Local to Remote loopbacks test the remote data port, the data path inside
the remote Campus unit, the HDSL line, the HDSL transceivers of both
units, and most of the internal data path inside the local unit. This
loopback does not test the local data port drivers and receivers.
• Remote to Remote loopbacks test the remote data port and a small
portion of the remote interface card.
Once a loopback condition has been initiated, it remains in effect until
cleared. You may also set a loopback timeout to clear the loopback
automatically after a set period of time has elapsed.
If both the local and remote units have a Campus-REX
interface card, no loopbacks are supported.
