24 x T1/E1
- Description:
- The Cisco 10000 Series 24-Port Channelized E1/T1 Line Card provides flexibility, scalability, and an enhanced price-to-performance ratio in the E1/T1 aggregation market. Targeted primarily at Internet service providers (ISPs) for situations in which fiber interfaces are unavailable or prohibitively expensive, the Cisco 10000 Series Channelized E1/T1 Line Card supports 24 E1/T1 ports (Layer 2 connectivity), each of which can be independently channelized down to DS0 or NxDS0. Layer 3 services are supported by the Cisco 10000 Series advanced Performance Routing Engine (PRE). By taking advantage of the advanced PRE architecture, ISPs will enjoy the necessary processing performance to enable the advanced IP services that users demand.
