DOCSIS 3.0 Cable Modem Boasts 160-/320-Mbit/s Downloads

A cable modem architecture introduced by Texas Instruments and based on the DOCSIS 3.0 specification enables fast adoption and deployment of advanced DOCSIS 3.0 products by cable operators. The Puma 5 architecture leverages TI’s experience in the cable industry by building on the company’s existing Puma family of cable modem technology to deliver the first DOCSIS 3.0 specification-based product to the market, according to TI. The new modem architecture features download speeds of 160 Mbits/s in the low-cost residential configuration and 320 Mbits/s in the business services configuration.

The Puma 5 is a flexible solution optimized for IP services—including voice, data, and video—with advanced home networking support to complete the gateway. The DSP-based Puma 5 incorporates TI’s Voice over IP technology. The new architecture supports Advanced Encryption Standard (AES), IPV6, and channel blocking for enhanced performance.

DOCSIS 3.0 is a CableLabs specification that delivers a new generation of high-speed Internet access to support high-definition multimedia applications, including voice and video, to cable subscribers. Migrating to a DOCSIS 3.0 network will not require a complete network rebuild, but only upgrades to the cable modem termination system and customer premises equipment.
