FAQ
What is G.SHDSL technology and how does it benefit my network?
G.SHDSL (Symmetric High-bit-rate Digital Subscriber Line) is a DSL standard that provides symmetric upload and download speeds over copper telephone lines. This technology benefits networks by offering consistent bandwidth for applications like video conferencing, file transfers, and cloud services where both upstream and downstream traffic are important. The 4-pair implementation in this card supports higher data rates compared to traditional DSL.
Which Cisco routers are compatible with this WAN interface card?
The EHWIC-4SHDSL-EA-RF is compatible with Cisco 1921, 1941, 2901, 2911, 2921, 2951, 3925, 3945, 3925e, and 3945e router models. This compatibility range covers both enterprise and service provider router platforms, allowing for flexible deployment in various network environments. Always verify specific router compatibility before installation.
What does EFM/ATM support mean for this interface card?
EFM/ATM support refers to Ethernet in the First Mile and Asynchronous Transfer Mode capabilities. EFM enables Ethernet services over first-mile copper infrastructure, while ATM provides a cell-based switching technology for efficient data transmission. This dual support allows the card to integrate with both modern Ethernet-based networks and legacy ATM networks, providing deployment flexibility in mixed infrastructure environments.
What are the physical dimensions of this WAN interface card?
The card measures 6.25 inches (158.75 mm) in height, 5.63 inches (143 mm) in width, and 1.75 inches (44.45 mm) in depth, with an approximate weight of 1.36 kilograms. These dimensions are designed for proper fit within compatible Cisco router chassis and standard equipment racks, ensuring adequate airflow and physical stability in network installations.
