connecting data modules to equipment in DC-powered cabinets.
Connect the data module to your house wiring or DEFINITY as follows.
1. Attach a D8W cable to the LINE port of the data module.
2. If you are going to attach a telephone to the data module
a. Attach a 400B2 adapter to the other end of the D8W cable.
b. Plug the adapter into a modular wall jack or 103A connector.
c. Plug a D7AP cord into the 400B2 adapter.
d. Plug the other end of the D7AP cord into the auxiliary power supply
for the telephone.
You must have a separate power supply for the telephone and for
