3.Connect one pair of wires to XMT+ and XMT- (transmit positive and negative) on the terminal block, making careful note of which color is positive, and which color is negative.

4.Connect the other pair of wires to RCV+ and RCV- (receive positive and negative) on the terminal block, again making careful note of which color is positive, and which color is negative. Your completed crossover cable should be pinned electrically as shown below:

XMT +	RCV+	} One Pair
XMT -	RCV -
RCV -	XMT -	} One Pair
RCV +	XMT+

5.When you finish connecting the wires to the terminal block, the assembly should resemble the diagram Figure 6 below.

The Model 1012B is now installed.

4.1.2 MODULAR TWISTED PAIR CONNECTION

The Model 1012B offers two interface options for twisted pair connection: RJ-11 (6-wire) jack and RJ-45 (8-wire) jack. Pages 9 and

10 show signal/pin assignments for the jacks, as well as pin-outs for the appropriate twisted pair cable topologies.

Signal/Pin Assignments

The 6-wire RJ-11 and 8-wire RJ-45 jack options for the Model 1012B are prewired for a standard TELCO wiring environment. Use the guide below when ordering or constructing twisted pair cables.

RJ-11	SIGNAL	RJ-45	SIGNAL
1	.GND†	1	. .N/C
2	.RCV-	2	.GND†
3	.XMT+	3	.RCV-

Crossover Cable Construction

Connection of a 4-wire twisted pair circuit between two or more Model 1012Bs requires a crossover cable as shown in the figures on the following page.
