Pre-Owned, Used And Refurbished Cisco ESR-24CT1/E1

The Cisco ESR-24CT1/E1 is a 24-port channelized E1/T1 line card and supports up to 24 E1 or T1 connections, with up to 744 channels. A fully configured Cisco 10008 chassis with two uplink half-height modules can support up to 168 E1s/T1s or up to 1,008 E1s/T1s per seven-foot rack. Two important benefits of the Cisco 10000 Series 24-port Channelized E1/T1 Line Card are its ability to provide full channelization as well as its ability to scale from 168 E1s/T1s per box up to 1,008 E1/T1 connections per seven-foot rack. It can also be configured with software to support either E1 or T1 on a per-card basis. This feature enhances its flexibility and augments services without changing the E1/T1 connection.

Marketing Information

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.
