J1 & J2 Utilizing individual 8 wire modular cords, connect the equipment to be protected (Digital Communicator,
8 PIN RJ Telephone Key Set, etc.) to the modular jacks J1 and J2. For optimum surge protection the cords should
MODULAR be 3 feet or longer. Pins 4 & 5 are RING and TIP going to the equipment. Pins 1 & 8 are R1 and T1
JACK returning from the equipment. Pins 2 & 7 are shorted together by jumpers to create closed circuit tamper

loops for supervising the modular plug. To convert to resistored EOL circuits, cut the jumpers and attach
the required resistors in series with the jumpers.
