RJ-ADAPT: RJ-31X Telephone Adapter

The Model RJ-ADAPT RJ-31X Telephone Adapter allows connecting the two telephone jacks on PERS-2400B or PERS-3600B Consoles to a Universal Service Order Code RJ-31X or RJ-38X telephone jack. These types of telephone jacks, wired per specification, provide proper telephone line seizure for the Console regardless if any telephone set is off-hook in the installation. RJ-31X or RJ-38X telephone jacks are wired to be the first jack closest to the telephone line demarcation point (the point where the telephone line enters the building). When there is no plug inserted into the jack, an internal shorting bar passes the telephone line signal directly to the local telephone sets. When the RJ-ADAPT plug is inserted into an RJ-31X or RJ-38X, the telephone line signal passes into the Console's LINE jack and out through the Console's PHONE jack back into the wall jack and out to the local telephone sets. When the Console's communicator is triggered and it needs to make a call, the Console disconnects the local telephone sets. This prevents off-hook local telephones from blocking the Console from seizing the line to acquire a dial tone.
