IP Telephony news wrap-up for Jun 20 – 2007

Texas Instruments has introduced TNETV2502, a low end IP phone based on the company’s TMS320C55x DSP and Adaptive Digital Technologies’ software. The phone supports basic phone features, one voice port (one channel of G.711 or G.729AB), PoE, and basic SIP signaling and call control capabilities. Conferencing and supplementary functions are reliant on the network. Additional Codecs are offered separately.

The TNETV2502 includes the silicon, software, and a complete reference design. It is scheduled for availability in Q3.

Separately TI said Network Physics has integrated its Piqua software into its voice quality management solution, NetSensory Solution Insight for VoIP 2.0. The management system gathers real-time voice metrics from IP endpoints (VoIP or IPTV), reports them, and when applicable, fixes them. The Piqua integration has been achieved through communication protocols such as RTCP-XR. Network Physics’ approach eliminates the need for agents, probes or synthetic handsets.

In other news, Grandstream is using TI’s acoustic echo cancellation software to improve speakerphone quality for its GXP2020, GXP2000 and BT200 IP phones. TI’s AEC features an algorithm witha 160ms tail, non-linear processing, double talk detection and AGC.

Microtune has introduced MT2064, a new tuner for DOCSIS 2.0 based VoIP cable modems and PacketCable based eMTAs. The tuner operates at frequencies up to 1 GHz, while using 800mW of power. The tuner includes an IF filter, low-noise amplifier, AGC, low phase noise, and high linearity. The tuner interfaces directly to standard demodulator chips.

The device is packaged in a miniature 6mm square chip that operates with a 3.3 Volt supply.

The MT2064 is currently sampling. Volume production is scheduled for Q3. The tuner is priced at $3.50 in quantities of 10,000. The supplier is also offering an evaluation board.

RadiSys has introduced the Promentum ATCA-9100 media resource blade, a DSP blade for use in VoIP, media processing and media gateway solutions. The architecture hosts up to 20 multi-core Freescale MSC8144 DSPs. The blade features packet and media processing capabilities via a 10 Gigabit Ethernet fabric and direct Ethernet access to DSPs. It features serial rapid IO switching and support for debugging of DSP code.

The ATCA-9100 is offered with onboard Linux, switching software, blade management software and other APIs.

Silcon Laboratories has introduced Si3226, a programmable, digital, dual channel SLIC and CODEC in a single chip designed for voice enabled cable and DSL modems, FTTP networking units and PBXs. The technology features remote diagnostic capabilities, low power operation through the use of a ring generator and battery tracking dc dc controller, and clear voice reproduction, boasting idel channel noise levels as low as 7 dBrnC.

The Si3226 is equipped with a 12-bit monitoring ADC and DSP engine that enable reporting of subscriber line faults. Fault isolation is enhanced through the support of two independent line-sensing paths per channel: one inside of the line protection and one outside. Diagnostic tests without the need for relays or dedicated test equipment.

Silicon Labs offers an API for the complete ProSLIC portfolio. The new SLIC is currently sampling. It is being shipped in a 64-pin TQFP.

Tektronix has introduced Orion, a service assurance solution for VoIP networks. The technology determines uptake rates, failure rates and performance trends. Analysis tools enable operators to determine which customers are affected by each specific network problem.

The company has also introduced the Interconnect Services module, which monitors and manages the quality of voice traffic from interconnection partners and wholesalers. The module delivers quantatitative reporting of performance by destination and carrier, traffic monitoring, LCR assessment, and an analysis of service and network problems identified through drill down in the Failed Call Log Summary and Call Trace.

Stealth Communications’ Voice Peering Fabric (VPF) ENUM Registry has added support for the routing of short message service, multimedia messaging service, calling name delivery information and presence.

Affiliates generate more than 500,000 minutes of IP traffic daily over Stealth’s VPF, which is a private distributed Layer 2 Ethernet network.
