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.

PRODUCT DESCRIPTION

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.

As shown in Table 1, a fully configured Cisco 10008 chassis with unchannelized E3/T3 line cards and redundant uplinks (using half-height modules) can support up to 56 E3s/T3s, or up to 336 E3s/T3s per 7-foot rack.

KEY BENEFITS

Scalability to Increase Services

The Cisco 10000 Series provides industry-leading scalability that enables an ISP to add more customers and services without requiring additional rack space in the POP. Using the e8-Port unchannelized E3/T3 line card, the Cisco 10008 chassis can scale from 56 E3s/DS3s to 336 E3s/DS3s. Another benefit is its ability to be configured through software to support either E3 or DS3 on a per-port basis. This feature enhances flexibility and augments services without changing the E3/T3 connection.
The scalability of the Cisco 10000 Series with e8-Port unchannelized E3/T3 card enables ISPs to stay ahead of the tremendous demand for Internet connectivity while at the same time making highly efficient use of scarce POP space.

Price and Performance Leadership

ISPs must be nimble, continuously providing new services such as quality of service (QoS), access lists, and Multiprotocol Label Switching (MPLS) virtual private networks (VPNs) to keep existing customers and to find new ones. But they also must be able to grow so that these new services are cost effective. The e8-Port unchannelized E3/T3 line card enables the Cisco 10000 Series to be one of the most cost-effective E3/T3 aggregation platforms on the market by:

• Integrating channel service unit (CSU) and data service unit (DSU) functionality right on the card, eliminating the cost of a standalone CSU/DSU

• Distributing costs over the largest number of ports, reducing the overall cost per port of the Cisco 10000 Series solution

• Enabling ISPs to continue to use the existing physical infrastructure of E3/DS3 circuits while supporting new IP services, reducing cost for the ISP and users

KEY FEATURES

• Eight ports of unchannelized E3/T3 or subrate E3/DS3 configured on a per-port basis

• Line rate performance at 44-byte or higher packet sizes

– Line remote defect indication (RDI)
