The module is designed for E1 or T1 signal applications. Normally one of the two
input signals is routed to the three separately amplified output ports. In the case of
power loss, the primary input port ("
In A
") is routed only to the first output port
("
Out 1
") and the other output ports do not carry any signal.
The unused input port is terminated internally.

The module is a 2:1 switch for optical signals. The optical common port ("
Com
") can
be switched to one of the two optical input/output ports ("
A
", "
B
"). The module is
shown here with the E2000 HRL connector option; other optical connector types
are available alternatively.
