Specifications

Product Overview:

The Cisco WS-X2951-XL is an ATM 155 UTP uplink module designed to extend the functionality of Cisco Catalyst 2900 XL Series switches by enabling high-speed Asynchronous Transfer Mode (ATM) network connectivity over copper cabling. This module supports 155 Mbps ATM over UTP (Category 5), offering an efficient and scalable solution for integrating legacy ATM infrastructures with modern Ethernet switching environments.
Built for enterprises and service providers seeking to bridge Ethernet and ATM networks, the WS-X2951-XL is ideal for quality-of-service (QoS) sensitive applications, such as voice, video, and data convergence. The module integrates smoothly with Cisco's end-to-end management tools and VLAN architecture, providing robust Layer 2 switching with advanced uplink capabilities.
Thanks to its plug-in form factor, this module is easily installed into any compatible Catalyst 2900 XL switch, offering flexible deployment options for high-speed backbone connectivity or wide area network (WAN) uplinks.
