Model C-377 100-Pair Connector

Model: 377-00XX

The CNI C-377 Central Office Connector has a space-saving design that provides up to 40% greater pair density when compared to older types of connectors. These connectors may be used on central office mainframes, wall-mounted and free- standing modular frames and Private Automatic Branch Exchange (PABX) grids.

The 279 mm high (11 inches) design does this without sacrificing any features. The protector module, jumper and test fields all employ a 5 x 20 configuration and are clearly labeled for easy identification. Stub cable and jumper wire terminations are completed using wire- wrap technology. Connectors equipped with a stub cable are shipped in the stub down orientation. The stub direction may be reversed in the field as required.

When installed on standard mainframes, the C-377 connector allows ample working space between frame verticals and does not encroach on aisle working room. The front-facing test field permits easy access for single or multi-pair testing. In addition, a unique “T-guard” prevents inadvertent contact with live circuits when removing protector modules from adjacent connectors.

The C-377 connector accepts the full line of industry standard 303-type, 5-pin protector modules including hybrid, solid state and gas tube modules. Because the contacts in the connector are tin-alloy plated, protector modules should also have tin-alloy plated pins to ensure optimal performance.
