the D8W cords into the MLX extension jacks specified on Data Form
1b, then go to Step 4.
If Data Form 1b does not indicate that you are to install MLX
telephones, plug each D8W cord into a 440A4 terminating resistor.
3 Using two more D8W cords connect each 440A4 terminating resistor to
the MLX extension jacks specified on Data Form 1b, then go to Step 6.
4 Connect the MLX telephones to the 7500B data modules.
