Cisco 2901

Cisco 2901 Integrated Services Router

The Cisco 2901 Integrated Services Router (ISR) is a modular router featuring embedded hardware encryption, voice and video capable digital signal processor (DSP) slots, optional firewall, intrusion prevention, call processing,and application services. The chassis offers a single Internal Services Module (ISM) slot, 4 eHWIC slots, 2 10/100/1000 WAN ports, 2 GE DSP slots, 256MB of Flash memory, and 512MB of DRAM in a 1U form factor. The Cisco2901 business router supports the industry's widest range of wired and wireless connectivity options such as T1/E1, T3/E3, xDSL, copper, and fiber GE.

Cisco 2901 Overview

The Integrated Services Routers Generation 2 (ISR G2) provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables you to grow and adapt with your business needs. The Cisco2901 offers a better level of services integration over its competitors. The Cisco 2901 integrates with voice, video, security, wireless, mobility, and data services offering greater efficiency and cost savings. (Visit the Cisco website to read about the network security features available for the Cisco Gen2 ISR routers.) Designed to address customer business requirements, the Cisco 2900 Series modular architecture offers increased capacity and performance as your network needs grow. Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.

Cisco routers are architected to meet the application demands of today's branch offices with design flexibility for future applications. The modular architecture is designed to support increasing bandwidth requirements, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). The Cisco 2901 is powered by a high-performance multi-core processor that can support the growing demands of high-speed WAN connections to the branch-office while also running multiple concurrent services. The 2901 also introduces an innovative multigigabit fabric (MGF) that allows for efficient module-to-module communication, enabling tighter services interactions across modules while reducing the overhead on the route processor. Unified communications services in the branch office are significantly enhanced with the use of a TDM interconnectivity fabric in the system architecture, allowing for scaling of DS-0 channel capacity.
