LOOPBACK
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.
