1. Alltel, Axtel, Cable Onda, & Completel to Deploy Nortel’s VoIP Gear
Nortel Network has named a set of new customer wins for its VoIP solutions including Alltel, Axtel, Cable Onda, and Completel.
Alltel, the 6th largest wireless company and 6th largest local phone company in the U.S., will deploy Nortel’s Succession Communication Server (SCS) 2000 softswitch, Packet Voice Gateway, and Succession Media Gateway 9000 to migrate select locations of its network in North Carolina and Georgia to IP. In addition to providing technology, Nortel will also provide planning, design, and implementation services. The softswitch will perform call control processing including centralized service delivery, routing, translation and signaling for switching VoIP calls between packet gateways on Alltel’s IP core network. With the new IP driven network, the provider will be able to offer local access, tandem function, and long distance services from a single softswitch.
Axtel, a Mexico based telecom service provider, will deploy Nortel’s SCS 2000 softswitch and Packet Voice Gateway to build an IP infrastructure for offering long distance services in markets new to Axtel including Saltillo, Aguascalientes, Tijuana, and Ciudad Juarez. Services are scheduled to be launched by the end of the year. Nortel will also be providing Axtel with design and implementation support.
As a second phase of its project to embrace IP, Axtel plans to migrate its existing network infrastructure to IP. The existing network provides telecom services to around 400,000 customers in Mexico City, Monterrey, Guadalajara, Puebla, Leon, Toluca, Queretaro, and San Luis Potosi.
Cable Onda, the largest telecom provider in the Republic of Panama, will deploy Nortel’s Compact SCS 2000 and Packet Voice Gateway to introduce VoCable services over its network in January of 2005. The cable operator serves Panama City, West Panama, and Colon markets 🙁
Completel, a France based telecom provider of services to medium and large businesses, will deploy Nortel’s VoIP technology to deliver a suite of enterprise based IP services such as IP Centrex. The new services are scheduled to be launched in the beginning of 2005.
3. CommASIC Unveils 802.11a/b/g Baseband Processors for VoIP Handsets
CommASIC has introduced LP1071 and LP1072, a pair of 802.11a/b/g, baseband processors designed with programmability for multimode broadband wireless applications. The ICs employ a single common hardware engine to support multiple communication modes – 802.11 b CCK and 802.11a/g OFDM. The processors draw 50mA during active receive mode at 54 Mbps and 0.4 mA in standby mode. Both ICs come with a development platform, SDIO and CF form fit reference designs to start customer design integration. In addition, the chips fully embed upper and lower MAC functionality inside the chip.
The LP1071, at 9x9x1.0mm, supports SDIO host interface. The LP1072 supports SDIO, CF+ and SRAM-to-host interfaces.
Final production ready ICs are available now in limited supply. Reference designs for evaluation and design integration are also available.
In addition to VoIP handsets, the processors are designed for use in wireless PDAs, digital cameras and other portable consumer electronics applications.
5. Engage Unveils Voice Gateway with Far End Echo Cancellation
Engage Communications has introduced the IPTube DLT1/E1 product line, a family of voice gateway appliances with two T1/E1 interfaces with either one or two active ports along with dual 10/100 BaseT Ethernet LAN ports. The new gateways include models that include Far End Echo Cancellation
The dual Ethernet interfaces can be used for:
The ECAN models with FEEC includes an integrated echo canceller that is compliant with ITU-T G.164, G.165, and G.168 requirements and supports PRI, SS7, CAS, CCS, proprietary out of band, and robbed bit signaling. The devices can cancel up to 64 ms of echo.
The ECANs utilize a DSP that detects and cancels echo at the far end, eliminating the impact of echo when there is packet network delay. The echo canceller samples the voice signal, and estimates and removes the echo. A linear DSP models the echo and performs the main echo cancellation task. A non-linear DSP processor then subtracts out any residual echo or reflected noise components.
ECANs enable organizations to interconnect phone systems over shared wireless Ethernet, busy intranets, and properly provisioned Internet connections.
7. Tektronics Introduces VoIP Testing Solution
Tektronics has introduced Spectra2, a VoIP testing solution that tests call capacity, system endurance, and end user quality. The test system consists of the company’s software and wideband trunking interface processing cards. Calls can be generated using SIP, H.323, MGCP, MEGACO, and SS7 ISUP. Media traffic can be generated across RTP and TDM voice paths simultaneously to test media gateways. Voice quality analysis tools are also included.
Spectra2 can generate 2,016 simultaneous calls with media per board, scaling up to six boards for a total of 12,096 timeslots per system. The WTI RTP board delivers 2,000 simultaneous calls with RTP streams per board, for a total of 12,000 RTP streams on systems equipped with six boards. Spectra2 version 4.0 can also support 126,000 calls per hour with voice quality analysis (PESQ).
