Greek broadband operator Hellas Online (HOL, part of the Intracom Group), has selected Cisco as the equipment supplier for a nationwide optical transport network expansion. The network, which is being designed and implemented by Intracom Telecom, employs Cisco fibre-optic and routing technologies over an IP next generation network (NGN) architecture. The HOL/Intracom proprietary fibre-optic network currently spans more than 3,500km nationwide, over which HOL offers residential voice and unbundled local loop ADSL broadband services via OTE’s local exchanges, as well as business services such as IP telephony, virtual private networks and direct fibre IP connections to offices. Dimitris Gorgias, network engineering and operations director at HOL, said: ‘Operating our own network, the second largest in the country [behind OTE], gives HOL an important edge over our competitors, and the new cooperation provides us with a future-proof platform to innovate and expand… our customers will experience faster installation times, higher-speed services and first-class reliability.’ HOL has deployed the Cisco ONS15454 Multiservice Transport Platform in the core and aggregation networks, supporting 40Gbps wavelengths. The Cisco Ethernet over dense wavelength division multiplexing (DWDM) Xponder line card technology used by HOL in the DSL aggregation network allows multiple DSL access sites to be connected to the IP core network using a single wavelength.
