IP Telephony news wrap-up for Jan 9 – 2006

Acoustic Technologies has introduced ATH3100, an IC designed for the implementation of full duplex speakerphones in desktop and VoIP speakerphones, and PBX and SOHO phones. The device supports up to 65dB of acoustic echo cancellation, 45dB of network echo cancellation, and up to 18dB of noise cancellation. Other chip features include dual voice band CODECs and digital PCM interfaces; sound quality support via 10-band equalizers, comfort noise, and AGC functionality; and support for handset and speakerphone modes, DTMF generation, ringer tone generation, and caller ID demodulation Type 1 and II.

The company’s embedded SoundClear technology provides operation with no clipping or distortion. SoundClear dynamically monitors, detects, and processes incoming voice, echo, and noise signal power levels.

An evaluation kit and tuning toolset are offered with the chip. The eXcho tuning allows users to customize settings and configurations as well as tune using a GUI interface.

The ATH3100 is currently sampling in a 48-pin LQFP. Later this quarter, the chips will be shipped in 48-pin QFN packaging.

PMC-Sierra has introduced a VoIP phone reference platform for the development of wired IP phones and VoIP Wi Fi phones based on the company’s MSP2020 VoIP processor and software along with Acoustic Technologies’ ATH3100 full duplex voice processor. The reference design package includes hardware schematics, a complete bill of materials, a software board support package, and support documentation.

The platform features voice security, echo cancellation, adaptive jitter control, phone features such as call forwarding and conferencing, support for multiple speech CODECs (G.711, G.723, and G.729ab), a status display LCD, and PSTN backup.

The MSP2020 eliminates the need for a separate processor, voice processing DSP, security chip and multiple Ethernet MACs. The security solution delivers encryption and decryption of voice channels without the need for a microprocessor or DSP.

Octasic Semiconductor has introduced OCT6100L, a new 130nm voice processor based on STMicroelectronics’ semiconductor technology. The L model, which joins an existing family of OCT1600 processors, allows development of devices that support down to 4 channels. The technology boasts a core voltage of 1.2V, requiring less than 1.5 mW per fully featured channel.

Features of the new L model along with other processors in the OCT1600 product line include:

  • Up to 672 channels G.168-2002 echo cancellation
  • 128ms tail/channel (on all channel densities)
  • Music Protection
  • Acoustic Echo Control
  • Adaptive Noise Reduction
  • Extensive signaling tone detection and generation
  • Audio Conferencing with Voice Quality features
  • Large buffer playback capabilities
  • TFO solution available
  • Field upgradeable algorithm
  • Integrated debugging and monitoring
  • size of 16mm x 16mm

    Samples of the OCT6100L are currently available. Production quantities are planned for early 2006, with pricing under $0.50 per channel in volume quantities.

    Broadcom has introduced a Wi Fi video phone chipset for the development of desktop video IP phones and wireless handsets. The solution consists of the BCM1161 mobile VoIP processor, the BCM4318E Airforce One 802.11b/g WLAN solution, the BCM2702 VideoCore multimedia processor, and various software packages.

    The technology supports H.264 and >263, video rates up to 30 fps, and QCIF to CIF full duplex video resolutions. The chipset includes a display controller supporting a wide range of LCD displays, as well as PAL/NTSC TV-Out. The WLAN device supports WMM, and WPA security. The associated software for the new chipset supports device configuration, improved wireless range and coverage, full duplex speaker- phone, image capture and display, video recording and playback and music player capabilities.

    The chipset is currently in production. A reference development platform and supporting software are also being offered. The platform includes a 30 fps video camera and color LCD display in a handheld phone housing. It also includes a SIP stack, WLAN OneDriver, and a Linux based board support package including drivers and software development tools.

    Linksys has introduced a SOHO IP PBX system along with new desktop IP phones, and an analog gateway for PSTN connectivity.

    The IP PBX, in its standard configuration, supports up to 4 users. However, with the addition of a software license key upgrade, the system can support 16 users. The SPA9000 includes support for more than 100 telephony features such as auto-attendant, music on hold, call transfer, call forwarding, group paging, intercom, call hunt groups, do not disturb, and 3-way conferencing. Other features including ACD/routing, bridged/shared line call appearance, DID and voicemail integration and a local and corporate directory.

    The vendor has introduced 5 new desktop IP phones. The low- end model, the SPA901 supports 1 extension, has 1 Ethernet port and no display. Higher end models such as the SPA942, can be upgraded to support 4 extensions, include 2 Ethernet ports with PoE functionality, and sport a monochrome display.

    The SPA3000 analog gateway features one FXO port and one FXS port. It supports PSTN failover and remote provisioning.

    ITSPs currently deploying the system include VoicePulse and RNK in North America; Telio in Norway; and Engin in Australia.

    The IP PBX goes for $400. The upgrade runs an additional $300. The new phones range in price from $90 for the SPA901 to $210 for the SPA942 with the 4 extension upgrade. The gateway is being offered for $90. An entire line of accessories are also available.

    Primus Telecommunications Group, an integrated communications service provider and primary line residential VoIP service provider, has received a Staff Determination Letter stating the company’s common stock is subject to delising from NASDAQ because the closing bid price was lower than a dollar. The provider has until June 12th of this year to comply with the requirement.

    Primus has requested a hearing concerning the delisting notice, which will delay the process.
