Cox Business Services launched Cox Carrier Services to help supply last-mile broadband and local transport over a metro area network, it says.

"Cox Carrier Services is not a separate division" of existing Cox Business Services subsidiary, says Cox spokesman Bobby Amirshahi. "It is a group of products sold by Cox Business Services … to carriers. The transport services are sold to any business needing metro area network services in any of our 22 markets."

The product line includes Cox Carrier Access, Cox Private Line and Cox FiberRing services.

Carrier Access provides a local loop alternative to ILECs, Cox says. Using a ring-in-ring-designed Sonet-based fiber optic network to interconnect with customers via an OC-12 or OC-48, the service also lets carriers pick from DS-1, DS-3, OC-3 or OC-12 connections for end users.

Cox Private Line service gives customers a choice of DS-3, OC-3, OC-12, OC-48 and OC-192 digital transmissions, the company says. The service provides point-to-point connections between POPs, and lets customers connect their own POPs or interconnect to another carrier, including ISPs, ILECs, IXCs, CLECs, BLECs or wireless carriers.

FiberRing allows access via a ring topology, equipped with restoration capabilities if the network fails, the company says. It also supports speeds of DS-1 through OC-48.

Amirshahi says Cox already has signed "a few significant contracts" with carriers and large companies, although he couldn't give details on what carrier transport services the company was presently selling.

"We hope to announce each separately, soon," says, adding that the contracts include Williams Communications, Sprint and Global Crossing.

Cox says all of the products the subsidiary offers provide secure connections through a self-healing, redundant network. The company also has deployed DWDM technology to increase bandwidth.
