Each of the 4 T1/E1s can be placed in loopback mode for testing and maintenance 
purposes. This provides a bi-directional loopback on the T1/E1 interface. The near end 
T1/E1 Transmit is looped back to the near end Receive, and the far end T1/E1 transmit 
that arrives over the BH Ethernet port is looped back to the far end Receive. 

The T1/E1 loopback remains in effect until the user removes the loopback through the 
CLI or through the EMS, or the system is reset. 

 

 

Invoking a T1/E1 Loopback will drop voice calls and disrupt user traffic 
flow.
