The H192 is a double density POTS splitter shelf. When populated with 8 NA 2820v cards, it delivers 192 ports in 2U of a standard 19 inch rack. The NA2820v is a 900:600 Ohm POTS splitter module, compliant with DSL services up to VDSL2. Each NA2820v connects 24 high-speed data lines and 24 voice circuits to 24 local loops, delivering voice and high-speed DSL services using standard 50 pin connectors.

The DSL connections are located at the front of the shelf and POTS and LINE interfaces at the rear. This design separates the DSL and voice connections from a common backplane, reducing crosstalk significantly, which is critical to Video applications. The DSL connection on the front is compatible with many DSLAMs, as the DSL line is often cabled out the front. Savings of time, effort and expense are achieved by simply running a short jumper cable rather then dressing the cable down the back to the existing Splitter.

The H192 is environmentally hardened to handle such locations as remote cabinets, as well as Central Offices. The option for secondary protection on both the PSTN and Line ensure voltage protection for power crosses and lightning surges, without manual intervention, or an expensive truck roll.
