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. The solution for Retecal includes an IP backbone network based on Nortel Networks Passport 8600 Routing Switches.
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 maximize the capacity available in each fiber -- up to 320 Gigabits per second 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 Gigabit per second streams, Gigabit Ethernet or 10 Gigabit Ethernet, as well as standard 10 Gigabit per second 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 innovative services including Virtual Private Networks (VPNs), Ethernet access networks, voice over IP, and advanced multimedia services with a focus on increased productivity and efficiency.
