Connections
The SHDSL T1/E1 LTU inserts into any access module
slot (1 through 28) of a Total Access 3000 chassis.
Power and alarm signals are provided to the module
through the backplane of the chassis.
The G.703 and SHDSL signals are transmitted/received
via the 64-pin backplane amphenol connectors. The
G.703 signal is transmitted to the network side via “Pair
8,” and the G.703 signal is received from the network
side via connector “Pair 7.” The SHDSL signal is trans-
mitted to and from the customer side via connector
“Pair 2.”
