Interface cable

MIM-1SHL-4W uses a tailor-made 4-wire telephone cable of type “Y” or “I”. You can select the type as
needed.

z

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 MIM-1SHL-4W module; on the other end there are
two RJ-11 connectors (X2 and X3), which can connect two 2-wire telephone lines. Pins 3 and 4 of
X1 are connected with pins 3 and 4 of X2, and pins 2 and 5 of X1 are connected with pins 3 and 4
of X3.

Connecting the interface cable

z

When using the “Y” cable, connect the X1 end of the cable to the interface on MIM-1SHL-4W and
connect the other two ends (X2, X3) to DSLAM through PSTN.

z

When using the “I” cable, connect one end of the cable to the interface on MIM-1SHL-4W and the
other end to DSLAM through PSTN.
