Running a loopback test
Remote Loopback
(valid only when in a
conference)
During VTEL HDLC calls:
Remote loopback tests all the lines at both
the local and the remote sites.
The local site sees the local site; the remote
site sees the remote site.
When you run a remote loopback test
during a VTEL HDLC call, the test functions
regardless of whether auto configuration is
enabled or not.
During H.221 calls:
The remote loopback test invokes digital
loopback at the remote site. The remote site
returns the communications signal to the
invoking site while continuing to process the
invoking site’s communication signal.
Both sites see and hear the invoking site.
Run the remote loopback test only when
auto configuration is turned off.
After you run the remote loopback test, turn
Remote Loopback off before you hang up
.
