Dansk Bredbaand a/s (DBnet) is using Cisco Systems’ equipment to deliver the triple play of services (voice, video and 10 Mbps data) over an Ethernet to the Home network. The network will serve an initial 10,000 residents in Copenhagen and across Denmark. DBnet is implementing the Cisco ONS 15454 Multiservice Transport Platform and Cisco 12000 Series routers in the core. A network of Cisco Catalyst 6500 Series switches act as broadband aggregation units at regional POPs. These provide Gigabit Ethernet connections to Cisco Catalyst 3550 Series switches for local aggregation in city block basements or enterprise customer premises. Other Cisco technologies used by the service provider include Cisco Universal Gateways and Cisco SIP Proxy Server call control software for voice over IP and Cisco provisioning solutions.

From the Technology Graveyard
You just read about Ethernet. Here is what it replaced:
Token Bus (802.4) served 1982–1990. What ultimately replaced it?
Token Bus (802.4) formed a logical token-passing ring over a physical coax bus, so factory-floor stations got deterministic, collision-free access (favored by GM's MAP initiative). Its job passed to Ethernet — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
