Celsian's ADSL IAD Passes Interoperability Testing With MetaSwitch's Broadband Voice Platform

Celsian Technologies Inc., a manufacturer of broadband voice and data products, and MetaSwitch announced that the Celsian Momentum V Series ADSL 4 port Voice Over DSL router has successfully passed interoperability testing with MetaSwitch's VP3000 Broadband Voice Platform.

The combined solution delivers toll-quality Voice over Broadband (VoB) telephone calls and subscriber services such as caller ID, call waiting, call forwarding and three-way calling, without requiring a Class 5 switch. Celsian has consequently become a MetaSwitch Interoperability Partner.

"Increasingly, vendors including ourselves are committing to open standards, such as the ATM Forum Broadband Loop Emulation Service (BLES), to accelerate the deployment of Voice over Broadband. The speed with which we were able to develop our IAD and achieve interoperability with the MetaSwitch VP3000 clearly demonstrates the benefit of this approach," said Carl Jaafar, CEO of Celsian.

Following a series of tests hosted at MetaSwitch's recently established facilities in California, the Momentum V Series IAD achieved interoperability with MetaSwitch's award-winning VP3000 Broadband Voice Platform.

By combining broadband voice and Class 5 switching functions in a high density, carrier class system, the VP3000 provides a cost-effective VoB solution, which is designed to eliminate the requirement for an expensive Class 5 switch. Support for the ATM Forum's Broadband Loop Emulation Service (BLES) also ensures interoperability with a wide variety of DSLAM and IAD devices.

In addition, the VP3000's future-proof softswitch architecture offers a clear upgrade path to Voice over IP and MPLS (VoIP/MPLS) and other broadband voice services, including wireless and cable.

Commenting on the significance of the result, Jaafar noted that "for the first time, we are in a position to offer service providers the option of deploying VoB with our IADs, without consuming legacy Class 5 resources.

"In addition, they can take advantage of Celsian's SmartCNCT Extensions, which allow for Port to Port and IAD to IAD calling, with mini-PBX features. Combined with the subscriber features built into the MetaSwitch VP3000, this creates a truly compelling service offering."

"We were pleased to work with Celsian to prove the capabilities of their IAD, and rapidly demonstrate interoperability with the MetaSwitch VP3000," said John Lazar, MetaSwitch's vice president of sales and marketing. "This is a testament to the maturity of the BLES standard and the ability of MetaSwitch and Celsian to collaborate effectively, for the benefit of our customers."

Celsian also has ADSL and SHDSL data products that have been certified by such companies as Nortel, Lucent, Copper Mountain, and Net to Net Technologies.
