Telephone Line Connections

The TI984 should be connected to the Central Office (CO) RJ11C jack from the telephone company or to a PBX with the 14-foot RJ11 interconnect cable. See your telephone company if a CO jack needs to be installed or extended.

The connection outlined in Figure 3 is recommended
because it allows the use of all the available types of
incoming modes. If the call from the CO is to be directly
connected to the Page/Party® system, use the bypass feature
available on the PBX.	Figure 3. Telephone Connections

Power

The unit can be powered by 115 or 230 V ac (50 to 60 Hz), or 24 V dc. If using ac power, connect the ac neutral wire (white) to terminal 6 and the ac hot wire (black) to terminal 2. See Figure 4. The earth ground wire (green or green/yellow stripe) should be connected to terminal 4. Set the Power Selector switch at the lower right of the power supply to the proper voltage setting (115 or 230 V).
