Activating T1 Inband Loopbacks

T1 physical loopbacks can be activated by receiving a loopback activation code

from TDM equipment connected to the T1 port. When IPmux-11 receives a

loopback activation code, it closes an external loopback (see

Figure 6-14), or

translates the TDM-based loopback activation code into the packet-based pattern

and sends it to the opposite IPmux device, which closes an internal loopback

(see

Figure 6-15).

The inband loopback can be activated only if the OAM connectivity is enabled

and only one bundle is configured for each port of the device.

An inband loopback is deactivated automatically, if:

• TDM connection is down

• Ethernet connection is down

• The user activated an internal or external loopback manually.



To activate an inband loopback:

• From the Inband Loop Detection menu (Diagnostics > Loopback > Inband

Loop Detection), perform the following:

 Select Loop Location and set it as follows:

 Local System (External loopback is activated in the local IPmux-11)

 Remote System (Internal loopback is activated in the remote IPmux-11)

 Disable (IPmux-11 ignores inband activation code).
