Optimized for high-quality voice services and data gateway applications, the DOCSIS 2.0 Puma 4 chipsets are based on an extremely flexible and extensible architecture that supports a wide range of applications and services.
With DSP and RISC cores, Puma 4 devices have the horsepower and the voice-processing capabilities for advanced VoIP features that differentiate equipment manufacturers and service providers in the VoCable marketplace.
Many cable operators require battery backup for voice services to ensure emergency communication service in the event of a power outage. The TNETC4700 Puma 4 device integrates battery control and charge monitoring functionality on-chip, eliminating the need for a discrete controller and reducing the system’s bill of materials cost substantially.
The voice/data solutions in the Puma 4 family include:
- TNETC4700/4710 – Voice-over-cable modem provides robust integration of all functionality for an embedded multimedia terminal adapter (EMTA).
- TNETC540 – A reference design for fast time-to-market, the TNETC540 incorporates the TNETC4700/4710 chips and supports high-speed data transfers through TI innovations like TurboDOX™.
