Cisco 2600 Series Modular Access Routers

As part of a scalable Data Communications Network (DCN) solution, including the Cisco Catalyst® 2950G-24-DC switch, Catalyst 2924M-XL switch, Catalyst

4003-DC switch, Cisco 3662-AC/DC-CO, Cisco 3631-CO, and Cisco 2600 Series modular access platforms, the Cisco 2600 Series supports central office (CO) serial, X.25 and Internet protocol/open system interconnection (IP/OSI) interfaces for operations management in Service Provider, Inter-Exchange Carrier (IXC), and Post, Telephone and Telegraph (PTT) networks. The Cisco DCN solution supports synchronous optical network/synchronous digital hierarchy (SONET/SDH) network element (NE) connectivity for alarm monitoring and control, remote provisioning, and software download. Other operations systems network applications include local number portability and billing data collection. In addition, competitive local exchange carriers (CLECs) can use the Cisco 2600

in small point of presences (POPs) or central office colocations for digital subscriber line access multiplexers (DSLAMs), voice switches, and transmission operations networking.

New Models in Cisco 2600 DC

Family: 2600XM-DC and

2691-DC

The Cisco 2600XM-DC models provides the same proven technology of the previous Cisco 2600 Series platforms, including Cisco IOS® software mainline feature support and the modularity of Network Modules (NMs), WAN Interface Cards (WICs) and Advanced Integration Modules

(AIMs). The Cisco 2691-DC-U model provides the same module support as the 2600XM, increased performance (up to 70kbps), and even greater density and scalability.

The modular architecture of the Cisco 2600 Series allows interfaces to be upgraded to accommodate network expansion or changes in technology as new services and applications are deployed. Service providers can integrate the functions of multiple, separate devices into a single, compact unit, thereby reducing the complexity of managing DCN infrastructures. For example, the Cisco 2600 Series supports connectivity to legacy asynchronous and X.25 devices as well as standards-based
