OOPBACKS
Loopbacks provide a way to test the data communication path between the
Campus unit, the remote unit, and the remote host equipment. Depending on
the remote unit, the Campus system supports the following types of
loopbacks:
• The Local to Local loopback tests the local data port and a small portion
of the Campus-REX RS Interface Card.
• The Local HDSL loopback tests the local data port and the entire data
path of the local Campus-REX RS Interface Card, including the local
HDSL transceiver. The data path in this loopback extends to the HDSL
line transformer, and causes the HDSL link to go down (a Link Alarm
occurs).
• The Remote to Local loopback tests the local data port, the entire data
path inside the local Campus unit, the HDSL line, the HDSL transceivers
of both units, and most of the internal data path inside the remote unit.
If both the local and remote units have a Campus-REX RS
Interface Card, no loopbacks are supported.
