Model C-303™ 5-Pin Non-Protecting Modules
Bourns® 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.
