The following table describes the LEDs on the FIC-1SHL-4W panel.
Interface Cable The FIC-1SHL-4W uses a tailor-made 4-wire telephone cable of type “Y” or “I”.
You can select the type as needed.
■ As shown in the following figure, on one end of the type “Y” G.SHDSL cable
there is one RJ-11 connector (X1), which is used to connect the FIC-1SHL-4W
card. On the other end there are two RJ-11 connectors (X2 and X3), which can
connect two 2-wire telephone cables. On X1, pins 3 and 4 are connected with
pins 3 and 4 on X2, and pins 2 and 5 are connected with pins 3 and 4 on X3.
