Pin	Pair	Name	Description
4	1	BL-W	2-Wire (Tip)

FAILURE TO FOLLOW THESE INSTRUCTIONS CAN CAUSE DAMAGE TO THE TERMINAL OR CAUSE THE ASSOCIATED DEFINITY® ECS CIRCUIT PACK TO REMOVE POWER TO THE TERMINAL. IN EITHER CASE, THE TERMINAL WILL NOT FUNCTION CORRECTLY.

For 2-wire operation, if you need to plug the voice terminal into a 4-pin or 6-pin wall jack, instead of a standard 8-pin modular jack, see the Modular Wall Jack Wiring table to ensure that the wires from the 4-pin or 6-pin wall jack are connected to the correct pins on the terminal LINE jack.

Two-wire installations must have only PBX connections on pair 1.
