CNI C(G)-390 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 also incorporate an angled mounting to improve access to the protector modules. They may be used on central office mainframes, wall-mounted and free-standing modular frames and Private Automatic Branch Exchange (PABX) grids. The C(G)-390 connector provides a comfortable working space between frame verticals and does not extend beyond the guard rail on standard frames.
The 279 mm high (11 inch) design reduces jumper running time with a front-facing jumper field. The jumper field is arranged in 5-pair groups that are clearly identified and numbered for easy identification. The integral front and rear fanning strips encourage neat and orderly wiring for quick installation and easier maintenance. In addition, the angled test field allows superior accessibility without interfering with rolling ladders.
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(G)-390 connector accepts the full line of industry-standard 303-type, 5-pin protector modules including hybrid, solid- state and gas tube modules. The protector module contacts in the C(G)-390 connector are available with either tin-alloy or gold- plating.
Accordingly, the plating on the pins of the protector modules should match the connector to ensure optimal performance.
