The Cisco® 10000 Series 8-Port Unchannelized E3/T3 Line Card provides flexibility, scalability, and an enhanced price-to-performance ratio in the E3/T3 aggregation market. Targeted primarily at Internet service providers (ISPs) for situations in which fiber interfaces are unavailable or prohibitively expensive, the Cisco 10000 Series Unchannelized E3/T3 Line Card supports eight E3/T3 ports (Layer 2 connectivity). Layer 3 services are supported by the Cisco 10000 Series advanced Cisco 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 8-Port unchannelized E3/T3 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 ports are software-configurable to support either E3 or DS3 on a per-port basis. Furthermore, a mixture of E3 and DS3 traffic can be supported on the same line card. The 8-Port unchannelized E3/T3 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 E3 or DS3 is the only service to a remote point of presence (POP). The line card supports Frame Relay, High-Level Data Link Control (HDLC), and Point-to-Point Protocol (PPP), thereby offering three different Layer 2 encapsulations of IP packets.
