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-24 receives a
loopback activation code, it closes an external loopback (see
Figure
6-15
), 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
6-16
).
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.
