Intermedia Takes Sonus Packet Telephony to Cities

Further validating its claims to providing scalable packet telephony, Sonus Networks Inc. this week announced a sale to one of the nation's leading next-generation carriers.

Intermedia Communications Inc., the Tampa, Fla.-based integrated communications provider that has branched out from its CLEC and frame relay roots, announced it is deploying Sonus' carrier-class packet telephony systems in eight major markets.

Intermedia said it has installed a 50,000-port Sonus GSX9000 Open Services Switch and PSX6000 SoftSwitch in Miami. Over the next few months it deploy similar equipment in Tampa, Atlanta, Charlotte, Raleigh, Indianapolis, Chicago and St. Louis.

The Sonus equipment will enable Intermedia to sell wholesale voice-over-IP services to a variety of customers. One of its key targets is IP-based long-distance traffic from international carriers. The Sonus switches will also enable Intermedia to offload modem-generated Internet traffic from Intermedia's voice network.

Sonus has played on its ability to go beyond traditional circuit-telephony-to-IP network gateways by packing the ability to carry thousands of calls onto two 19-inch racks, largely by removing packet-telephony resources such as digital signal processing from central processors and distributing them onto the port cards. Its product suite also emulates many of the service-creation features found in more-expensive central office circuit switches such as the Lucent 5ESS.

Sonus has earlier scored contract wins with Global Crossing, Time Warner Telecom, BroadBand Office and others.
