IP Telephony News Wrap-up for Nov, 22 2004

1. LSI Logic Unveils Line of DSP Solutions for Voice Applications
LSI Logic has introduced Z.Voice, a family of DSP solutions for the development of equipment that would support voice applications such as VoWi-Fi in cell phones and cordless phones, voice ports in DSL and cable modems, residential gateways and SOHO routers. The line includes products that provide varying levels of support for VoIP channels, ranging from 2 to 32 channels.

The LSI402ZX DSP is designed for applications that require high data throughput coupled with high-speed I/O such as communications equipment. It is a 16-bit fixed point DSP (200 MHz/800 MIPS) that features 62kW instruction/62 kW data memory, a 16/32 ext. memory interface, 2 high speed TDM serial ports, a 16-bit HPI, an 8 channel DMA controller, 2 16-bit timers, and 124K words on chip RAM. Support is provided for 8+ channels of VoIP. The DSP is packaged in 208 mBGA.

A development kit, known as the DK402 is offered with the LSI402ZX, enabling developers to evaluate the ZSP400 DSP core, and to develop software or prototype a design that includes the LSI402ZX. The kit integrates a DSP evaluation board (EB402), full-version software development tools, a board support package, example source code, a MP3 player and Vianix MASC CODEC demonstrations, tutorials and complete documentation. The kit also includes a 30-day evaluation of GHS MULTI Tools.

The LSI403LC is a 16-bit fixed point DSP (120 MHz/480 MIPS) that features 48kW of on chip RAM, one high speed 128-channel TDM serial port, an 8 bit HPI, an enhanced 8 channel DMA controller, and 2 16 bit timers and 4 general purpose I/Os. Support is provided for 1-4 channels of VoIP. The DSP is packaged in 128 PQFP (14x20mm).

The LSI403LP is a 16-bit fixed point DSP (150 MHz/600 MIPS) that features 48 kW of on chip RAM, a 16/32 ext. memory interface, 2 high speed TDM serial ports, an 8 bit HPI, an enhanced 8 channel DMA controller, and 2 16 bit timers. Support is provided for 4+ channels of VoIP. The DSP is packaged in 208 PQFP and LBGA.

A development kit for the LSI403LP, known as DK403, is also offered. It contains all of the components included in the DK402 kit, but is designed for developing software or prototypes using the LSI403LP.

The new DSPs are licensed. Block diagrams for each are provided on LSI Logic’s web site.

In addition to these new DSPs, the Z.Voice product family also includes a suite of vocoders and application software solutions for such protocols as G.711, G.729, G.729A/B, and G.723.1.

The Z.Voice 729 is an off the shelf, bundled silicon/software package offered that includes multiple vocoders including G.711, G.729, and G.729A/B. It is designed to be a quick fix for implementing voice support into a product design.

The new product line also includes VoIP reference designs such as one for a VoIP wireless router, developed with Micrel.

Z.Voice includes a roadmap of backward compatible DSP cores consisting of the ZSP200 (single MAC), the ZSP400 (small footprint, dual MAC), the ZSP500 (high performance dual MAC), the ZSP540 (small footprint, quad MAC), and ZSP600 (6-issue quad MAC).

5. APconnections Introduces Bandwidth Prioritization Technology
APconnections has introduced the NetEqualizer product family, a series of bandwidth prioritization devices that allow service providers and businesses using VoIP to prioritize voice traffic in their networks.

NetEqualizers track connections on the network and when congested, allocates bandwidth according to application. Voice traffic is given the most bandwidth, followed by web, chat and email traffic. The biggest bandwidth squeeze is put on P2P applications and downloads.

NetEqualizers are interoperable with IP PBX solutions offered by multiple vendors.

A NetEqualizer configured to handle up to 2 Mbps of bandwidth goes for $995. One configured to support up to 45 Mbps is priced at $2,750.


7. VoIPAction Selling Database of N.A. VoIP Providers & Vendors
VoIPAction, a publisher of a market information web site on VoIP, has compiled a list of more than 400 companies offering VoIP services in North America and 450 VoIP carrier network and equipment suppliers. The database, available in an Excel spreadsheet, provides company names, web site addresses, and phone and email contact information.

The list is available for $1,495.


9. Mera Introduces VoIP Service Creation Platform
Mera Networks has introduced SIPrise, a VoIP service creation platform that enables carriers to deliver a variety of services such as IVR, calling cards, conferencing, and idependently developed services. SIPrise can also be used to run pure VoIP call shops and offer IP Centrex servicees.

The platform supports the delivery of multiple IVR services to enterprise users such as auto attendant, employee notification, call center automation, customer surveys, bill reminders, and independently developed IVR apps.

SIPrise can support up to 5,000 concurrent calls. It supports both H.323 and SIP.

In other news, Mera has said Uzbektelecom, Uzbekistan’s largest provider of telecom services, has deployed MERA’s MVTS Session Controller in its nationwide VoIP network.
