Model C-388 100-Pair Connector

The Comtest C-388 Central Office Connector has an efficient and 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 C-388 connector provides a comfortable working space between frame verticals and does not extend beyond the guard rail on standard frames.

The 279 mm (11 inch) high design reduces jumper running time with a front-facing jumper field. The jumper field aligns the terminals for each tip-ring pair vertically and places them in groups of five. Each group is clearly numbered adjacent to the jumper and test field. The integral front and rear fanning strips encourage neat and orderly wiring for easier maintenance.

The 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.

The C-388 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.
