The following table describes the LEDs on the MIM-1SHL-4W panel.

Table 99 LEDs on the MIM-1SHL-4W panel

LED	Description
LINK	OFF means no link is present.
	ON means a link is present.
ACT	OFF means no data is being
	transmitted or received.
	Blinking means data is being received
	or transmitted.

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.

■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.
