Loopback
Loopback is provided for any enabled TDM port. The choices are:
•
No Loopback (default)
•
External (local)
•
External (remote)
All loopback configurations control the loop at the Line Interface integrated circuit, which is the
device wired directly to the front panel ports.
External loopback modes are used in conjunction with an external test source. The designation of
‘local’ or ‘remote’ refers to where the loopback is occurring relative to the location where the loopback
is implemented. That is, on the radio being accessed, if External (remote) is selected, this loops the
signal back at the remote radio interface back towards the local radio. Likewise, if External (local) is
selected, the signal loops back at the local interface towards the remote radio (Figure 37 and Figure
38).
