Features ■ Rugged construction Model C-303™ 5-Pin Non-Protecting Modules Bourns® Model C-303™ Non-Protecting Modules provide continuity or ground in a 5-pin type protector for use in central office connector, remote and building entrance terminal applications. The housings are made of colored self-extinguishing insulating material. When inserted into the connector sockets, contact pins provide the following connections for each cable pair: • ground that also acts as a polarization pin • tip and ring to the outside cable • tip and ring to the central office equipment Non-protecting modules are available with tin-alloy or gold-plated outside plant and central office pins; the grounding pin is always tin-alloy plated. • Non-protecting modules with gold-plated pins are intended to be used in connectors with gold-plated protector receptacles. • Tin-alloy plated pins can be used when the protector receptacles are tin-alloy plated. 5-Type Direct Feed Modules These modules give circuit continuity between the outside plant and central office pairs. Used in locations where protection is not required. Straight-Through Module Denied Service Grounding Modules These green-colored modules are used to temporarily disconnect a subscriber’s line. The modules provide a permanent ground on all terminated outside plant cable pairs that are not being used or those that are in an idle condition. This prevents noise induction to the adjacent circuits. There is no connection on the central office equipment pins.
