Lead Connections
This voice board connects to your telephone system as a series of single-line devices.
Connect each modular jack on the voice board to your telephone system with a modu-
lar lead. This board has four modular jacks to connect four voice ports. Each modular
lead connects one port or channel. Each plug is one port.
Configure the Voice Board
Each D/42PA voice board in the system must have a unique memory address. The
board' s dip switch and jumpers set this address. The board diagram (on the other side
of this sheet) shows where to find the dip switch and jumpers.

Set the new board' s dip switch SW1 according to the figures below, based on how
many
voice
boards are in the system.
Locate jumper JP7. The first voice board installed in the system must have JP7 on.
Any additional voice boards must have jumper JP7 off.
Locate jumper JPI on the new voice board. JPl sets the board' s hardware interrupt
(IRQ). Place a jumper on the pair of pins for IRQ 5 (see figure).
Check
that jumpers JP5 and JP6 are set to Off. This sets the voice board to use the D
memory segment.
Install the voice board.
