Motorola today expanded its family of voice-enabled cable modems with the introduction of the SBV5100 series. The new models, based on the Session Initiation Protocol (SIP), one of the more common voice and multimedia protocols in the telecommunications industry, provide greater choice to cable operators as they select the ideal technology for their systems.

With the pending emergence of PacketCable 2.0, which includes IP Multimedia Subsystem (IMS), many cable operators are adopting or evaluating SIP-based devices for their networks allowing consumers to "hand off" a cellular call to a Wi-Fi network and landline phone, rich multimedia communications, such as interactive video sessions, secure signaling and encryption, and flexible Network Address Translation (NAT) and firewall traversal technologies like Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (STUN).

As part of Motorola's broadband family of telephony products, the SBV5100 series converges voice and data, on one network, in one product. By combining multiple services in one unit, consumers can enjoy an efficient solution that offers many advantages over competing technologies, and provides a pathway to advanced voice services. The SBV5100 supports full-featured primary Voice-over-IP (VoIP) telephone service for up to two telephone lines that are terminated in two RJ-11 connectors. In addition, its integrated cable modem connects to a computer through either a 10/100Base-T Ethernet or a USB data port. The SBV5100 enables:

• One infrastructure for communication services
• One bill for voice and data services
• Simultaneous use of phone line and high-speed data services
• Support for a variety of CLASS features provided today by the telephone company (caller ID, call waiting, call forwarding, etc.)

The Motorola SBV5100 series is expected to be available by the end of 2006.
