Loop Function

T1 local An incoming T1 signal is looped back to the T1 line. AIS is injected towards

the T13 MUX. T1 local loop is set for all the ports belonging to a particular T1

channel module. For HS modules, the loop can be set separately for each port

belonging to a particular HS channel module.

Fiber optic local The outgoing fiber optic signal is looped back towards the T1 and Ethernet

ports. AIS is injected in the outgoing fiber optic signal towards the link and

propagated to the T1 signals in the remote Optimux-XLT1.

T1 remote The received T1 signal is looped back towards the link. AIS is injected in the

T1 signal towards the T1 line. The T1 remote loop is set separately for each

port belonging to a particular T1 channel module.

Before setting the fiber optic local loop, set the clock source to INT and set the link

redundancy to OFF.
