Spanish cable operator taps Nortel for routing switches, optical equipment

Jan. 16, 2003
January 16, 2003--Retecal, a cable telecom operator in Spain's Castilla-Leon region, has upgraded its data network to an open Internet Protocol (IP)-based system and increased its overall DWDM infrastructure capacity by deploying routing switches and optical equipment from Nortel Networks.

Retecal, a cable telecom operator in Spain's Castilla-Leon region, has upgraded its data network to an open Internet Protocol (IP)-based system and increased its overall DWDM infrastructure capacity by deploying routing switches and optical equipment from Nortel Networks.

Nortel' solution for Retecal includes an IP backbone network based on the Nortel Passport 8600 routing switches. The network was designed to satisfy Retecal's requirements for network reliability and scalability for a range of multimedia applications.

Retecal is using the content intelligent capabilities of Nortel's Alteon Layer 4-7 Web Switching Module, integrated with Passport 8600, to accelerate Internet content access. Retecal is also using Alteon Content Cache to improve content delivery on the information most frequently requested by end-users, which reduces traffic by off-loading repetitive tasks from servers.

The Spanish cable operator has also deployed Nortel's OPTera Long Haul 1600 Optical
Line System, an optical platform using DWDM, to maximize the capacity available in each fiber--up to 320-Gbits/sec per pair. This allows Retecal to implement virtual transport infrastructures for third-party carriers. OPTera Long Haul 1600 offers service transparency and the ability to add various channels, such as 2.5-Gbit/sec streams, Gigabit Ethernet, or 10-Gigabit Ethernet, as well as standard 10-Gbit/sec SDH wavelengths.

The new network positions Retecal to improve the Internet experience for its customers, both residential and corporate, and to extend its portfolio with new products and services, including Virtual Private Networks (VPNs), Ethernet access networks, voice over IP, and advanced multimedia services.
