Loopbacks on the network port
The network port loopback sends network data back to the network, testing the
SHDSL line and the data interface at the network port.
Loopbacks on the network port are timed. Timed loopbacks have a fixed duration of
5 min, although the loopback can be cleared manually before the 5 min expires.
Procedure 13-2 Configuring a loopback
MAINT — OBJECT — PORT — <N>
↵
— LOOPBACK — LINE — TIMED
Procedure 13-3 Removing a loopback
MAINT — OBJECT — PORT — <N>
↵
— LOOPBACK — LINE — CLEAR
13.3 User and T1/E1 port maintenance
The following maintenance options are available for the user and T1/E1 ports:
•
enabling and disabling the port
•
resetting the port
•
performing a loopback on the port
•
verifying the status of the data stream (frame relay user port only)
Figure 13-4 shows an example of a frame relay NMTI screen for user port
maintenance information.
Note — If a Telnet session is used to access the Speed Touch 591s
NMTI, the loopback cannot be cleared before the 5 min expires.
Note — If a loopback is already active, an error message is displayed.
Note — Loopbacks can also be initiated remotely on the network port by
any CO device supporting EOCs. Loopbacks set on the network port in
this way are latched rather than timed.
