ntl taps Nortel for network migration; Converges on Convergys billing

ntl Telewest is upgrading its optical backbone from Nortel with dense wavelength division multiplexing (DWDM) technology to expand capacity as it migrates from a circuit-switched business to an IP-based packet network.

The additional capacity afforded by the upgrade will help ntl Telewest deliver more fixed-line voice, video and data services to residential and enterprise customers in the U.K., and will assure the company sufficient bandwidth when it eventually begins offering wireless voice.

The DWDM installation is a natural extension of the relationship between the two companies. Nortel is adding the DWDM upgrade to WDM and SDH networks it earlier built for ntl Telewest. Last March, ntl Telewest announced it had begun to source softswitches and multimedia routers from Nortel.

The DWDM upgrade includes the Nortel Common Photonic Layer (CPL) and Optical Multiservice Edge (OME) 6500 convergence platform enabling circuit to packet migration. Together, they will simplify aggregation and transit nodes while expanding capacity over an adaptive, intelligent and efficient optical layer.

Separately, ntl Telewest decided to continue sourcing billing systems from Convergys, which was far from a foregone conclusion.

Convergys got into the ntl account from two different directions. The first was through ntl's acquisition of Telewest, a Convergys customer since 1996. That acquisition was completed in March. The second path was through Convergys' acquisition -coincidentally also in March - of U.K.-based billing system provider Geneva Technology. Geneva was only one of ntl's billing system suppliers.

Convergys said ntl Telewest is replacing four architecturally and technologically different legacy billing systems with Convergys' ICOMS customer care and billing products. ntl Telewest should be on the single Convergys platform sometime in 2007.
