Spanish cable operator deploys optical equipment from Nortel
16 January 2003 -- Spanish cable telecom operator Retecal has upgraded its data network to an open IP-based system and increased its DWDM capacity by deploying routing switches and optical equipment from Nortel Networks.
16 January 2003 -- Retecal, the 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 dense wavelength division multiplexing (DWDM) infrastructure capacity by deploying routing switches and optical equipment from Nortel Networks.
Nortel Networks' solution for Retecal includes an IP backbone network based on its 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 Networks 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.
Retecal has also deployed Nortel Networks OPTera Long Haul 1600 Optical Line System, an optical platform using DWDM, to maximise the capacity available in each fibre -- up to 320Gbit/s 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 2.5Gbit/s streams, Gigabit Ethernet or 10 Gigabit Ethernet, as well as standard 10Gbit/s SDH wavelengths.
The new network positions Retecal to improve Internet use for both residential and corporate customers, 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 with a focus on increased productivity and efficiency.
"We have designed a new network infrastructure, based on Nortel Networks solutions, making Retecal one of the most technological advanced companies in the region," said Retecal's CEO Juan Garcia Conde.
