Product Description

Comtest Networks’ System-5 NA-2820VE Splitter is designed for installation in the H192, a high density, modular solution for VDSL2 splitter applications.

The H192 is situated between the subscriber lines and the CO-serving equipment.

Ideal for remote cabinets, Comtest’s H192 double-density splitter shelf allows you to boost capacity without consuming excessive rack space. The unique front/back connections create a clean cable management solution.

The H192 compact design houses 192 ports in 2U of a standard 19-inch rack. All DSL connections are at the front of the shelf and all PSTN and LINE interfaces at the rear. This separating of DSL and voice connections significantly reduces videoimpairing crosstalk. The H192 is environmentally hardened for demanding locations.

The backplane contains make-before-break connectors from the outside plant tip and ring to the POTS tip and ring, respectively, to maintain “LIFE-LINE” service when a line card is removed from the chassis.
