E1
and
E1 FAR
loopback modes loop signal back to local end and to remote end respectively
in bounds of E1 interface. E1 loopback mode must be set on the particular channel you need
to test. If no E1 channels are selected, E1 loopback mode is not available. E1 loopbacks are
named “interface” and “interface far” in “Loopback name” dropdown menu.
•
MODEM
loopback mode loops signal back to local end after the modem.
•
IF
loopback mode loops signal back to local end by linking intermediate frequencies.

Loopback configuration
1.
Loopback name –
allows choosing loopback mode (command line –
loopback
{status | none | if | modem |e1 <num> [far] | e1 mask <mask> [far]} [<time>]
);
2.
Loopback timeout –
allows specifying activity time of chosen loopback mode in
seconds (command line –
loopback
{status | none | if | modem |e1 <num> [far] |
e1 mask <mask> [far]} [<time>]
);
