New Whitepaper: From Host-Remote to Next-Generation

Traditional telephone switching systems support the concept of "host-remote" operation, whereby lines are terminated by equipment in remote locations that is under the control of a host switch -- but potentially with the ability to operate independently of that switch if the control link is cut. With the emergence of next generation networks, a distributed "softswitch" architecture offers the same ability to reliably deliver services across a wide geographic area with several improvements over the previous generation of equipment. Most important of these are: multiple levels of emergency standalone operation; open interoperability; connectionless trunking in a packet network; distributed PSTN connectivity; and host site redundancy.

Tele2 Selects Huawei for SDH Equipment

Tele2 awarded a European Frame Supply Agreement to Huawei for its SDH optical transmission equipment. First equipment rollout has already started in Austria for the expansion of UTA's broadband access network. UTA was acquired by Tele2 in 2004. Financial terms were not disclosed.

Huawei described the contract as an important breakthrough in the Nordic and European operator market.

Huawei Wins DSLAM Contracts for 3 Million Lines in China

Huawei announced contracts to supply 3 million DSLAM ports in China , including 1.71 million ADSL lines from China Telecom, and 1.3 million ADSL lines from China Netcom. Financial terms were not disclosed. Huawei noted that it has been awarded the biggest DSLAM contracts in China for 7 consecutive times since 2003.

Intel Develops CMOS Radio Supporting All Flavors of 802.11

Intel has developed a prototype of an all-CMOS direct conversion dual-band radio transceiver capable of supporting every current Wi-Fi standard (802.11a, b and g), as well as the projected requirements of 802.11n. The device integrates a 5GHz CMOS power amplifier that meets all the spectral purity and non-interference requirements from the FCC, while frequency planning techniques minimize interference caused by the on-die amplifier. To achieve these results, Intel researchers developed a new calibration scheme for the transceiver to achieve high volume manufacturability. Separating receiver and transmitter effects has proven to be difficult in the past, but Intel said its scheme is easy to implement and correctly separates the effects, improving yields and lowering the cost of these radios.

Entrada Networks Offers 16-Channel CWDM

Entrada Networks announced the availability of a 16-channel CWDM Metro Area Transport Platform through its wholly owned subsidiary Torrey Pines Networks. Entrada's line of CWDM products, which also includes 8-channel modules, supports 2.5 Gbps data rates.

Intersil Introduces HDTV Video Sync Separator

Intersil introduced a new sync separator that extracts sync timing information from both standard and non-standard video inputs. This timing information is critical to the detection and alignment of different formats on a screen. The device, which supports HDTV and standard definition formats, provides composite sync, horizontal sync and vertical sync outputs. It requires no external programming or set resistors.

Motorola Hires Telcordia/Lucent Exec to Head Global CDMA Organization

Motorola hired Teresa (Terry) Vega to lead its CDMA organization. She will be based at Motorola's South Plainfield, New Jersey, facility and report directly to Ron Garriques, executive vice president, president of Motorola's Mobile Devices Business. Vega most recently served as Group President of Wireless, Cable and Emerging Markets of Telcordia Technologies, a supplier of software solutions for network management and operations. Previously, Vega served as Chief Operating Officer of Lucent's wireless infrastructure business, managing the AMPS, CDMA and TDMA segments.

Digiweb Acquires Tiscali's Italian Satellite Business

Digiweb, which provides broadband coverage in Ireland and Europe using a combination of Fixed Wireless, Two-way Satellite and fixed line DSL, has completed the acquisition of Tiscali's satellite broadband business in Italy for an undisclosed sum. Using industry leading satellite technologies and a range of satellite uplink operators, the two-way satellite broadband technology enables Digiweb to provide high speed broadband access throughout all of Europe, including many areas that the national operators do not service, without any reliance on the fixed line telephony infrastructure. In addition to Italy, Digiweb is already servicing business customers throughout Germany, France, United Kingdom and Austria.
