Product Line(s)

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.

The 24-port channelized E1/T1 module is a full-height line card that supports maximum flexibility and can be used in any Cisco 10000 Series interface card slot. All cards are hot-swappable. The RJ-48c ports software-configurable to support either T1 or E1 (120-ohm) interfaces on a per-card basis, meaning all 24 ports in either E1 mode or in T1 mode. The 24-port channelized E1/T1 line card may be used in many customer applications. It is ideal for providing direct customer IP access or network-to-network connections where copper E1 or T1 is the only service to a remote point of presence (POP). The line card supports Frame Relay, High-Level Data Link (HDLC), and PPP, thereby offering three different Layer 2 encapsulations of IP packets.
