CableLabs developing SIP trunking standards for business voice.

Posted by on April 22, 2010 No comments
Cable companies offer a number of residential VoIP services, but to land large business accounts they need more advanced technology. While some cable companies are offering their residential-style VoIP services to small businesses, most are looking forward to the day when SIP Trunking will allow them to really handle the load most big businesses require. Enter CableLabs. They are working on a SIP Trunking extension to the PacketCable 2.0 to allow MSOs to interoperate with PBXs and land bigger business customers.
CableLabs’ SIP Enterprise Connect, being developed in conjunction with SIP Forum and the Internet Engineering Task Force, will eventually be published as a PacketCable 2.0 extension. The extension will be aimed at creating an industry-wide spec for interconnecting IP-PBXs and MSOs dictating how softswitches, PBX gear, telephony application servers, session border controllers, and gateway devices will all work together under the standard.

Google’s Transpacific Fiber.

Posted by on March 23, 2010 No comments



A new Transpacific fiber link, dubbed Unity, is nearly ready and should increase lit cable capacity by around 20 per cent.

The $300 million, 7.68 Terabits/ cable was funded by Google and six Asian telecommunication firms; Singapore Telecommunications, Bharti Airtel, Global Transit, KDDI Corporation and Pacnet.

Two ships have been laying the cable from a midpoint in the Pacific to each of the two landing points. Tyco Telecommunications (now called SubCom), installed the undersea cable from the U.S. end using the Tyco Resolute (photo), while NEC installed the undersea cable from the Japan end.

NEC’s cable ship landed it’s section in Chikura, Japan, on November 2, 2009. The Unity system uses OCC-SC300 cable, with the latest DMF optical technology (right).

Google is building a server farm in Malaysia which it wanted to connect to the US. They went into the market but could not get the price they wanted so came up with the idea of a mini-consortium, according to reports.

The new underwater cable will have 5 fiber pairs, each with a capacity of 960 Gbit/s, and will be expandable to 8 fiber pairs. This will give the cable a total capability of 7.68 Tbit/s.

Handmade VoIP by Time Warner Cable.

Time Warner Cable has decided its time to leave Sprint’s services behind and strike out on its own with voice service. While cable companies have long had wholesale agreements with certain carriers, as competition heats up some are looking for ways to bring these lucrative services in house.
A report by Craig Moffett of Bernstein Research revealed that Sprint’s contract with Time Warner Cable “equates to about $5 per subscriber per month in unadjusted earnings, or about $249 million a year.” TWC has over 4 million subscribers using the Sprint system for digital voice service.
Time Warner Cable spokesman Justin Venech would not confirm the exact date when this transition will be completed or what TWC pays Sprint for this service, but some sources say it will be within the next four years. “It improves our economics, but it will take several years to complete,” Venech said.
