Description
The Cisco EHWIC-4SHDSL-EA is a high-performance Enhanced High-Speed WAN Interface Card (EHWIC) designed to deliver reliable and scalable G.SHDSL connectivity for enterprise branch offices and service provider environments. This compact module supports up to four 2-wire or two 4-wire SHDSL circuits, allowing for flexible deployment across a variety of DSL infrastructures. Built for integration with Cisco ISR G2 routers, it enables symmetrical data rates of up to 15 Mbps per pair, ideal for mission-critical applications requiring consistent upstream and downstream bandwidth. The card features a robust design with four RJ-11 ports and uses the ITU-T G.991.2 standard for SHDSL operation.
Equipped with advanced diagnostics and loopback testing capabilities, the EHWIC-4SHDSL-EA allows for simplified troubleshooting and maintenance in complex network setups. It supports ATM and EFM bonding, enabling increased throughput and redundancy by aggregating multiple DSL lines. This used unit typically includes the main circuit board, port connectors, and mounting hardware, all designed for seamless installation into compatible Cisco ISR G2 chassis. Its efficient form factor and low power consumption make it a cost-effective solution for extending WAN connectivity without compromising performance.
