Cisco's IP DSL enables carriers to cast net wider

Cisco last week claimed that its latest digital subscriber line (DSL) offerings will enable carriers to extend the reach of their services by around 30 per cent.

Cisco last week claimed that its latest digital subscriber line (DSL) offerings will enable carriers to extend the reach of their services by around 30 per cent.

The networking giant will also begin adding IP DSL switching technology to its 6000 DSL range to allow service providers to carry IP traffic over ATM. This will enable sites to introduce quality of service (QoS) policies on IP over ATM networks, the company said.

The first product to feature the IP DSL technology is the 6015 IP DSL switch, which enables service providers to support so-called multi-tenant units (MTU), as well as central offices and remote terminals for IP and ATM-based data, voice and video services.

Cisco also announced support last week for the industry's G.shdsl (single-pair high-bit-rate DSL) standard which enables carriers to extend the reach of their DSL services by 30 per cent to 18,000ft. The standard enables products to support multiple bit rates over one pair of copper wires in IP and ATM environments.

Enzo Signore, director of marketing for the Cisco DSL and integrated access business unit, said: "The DSL subscriber market has been largely under-served either because of distance barriers from the central office, or in the case of the MTU and remote terminal markets, the lack of the right equipment."
