connections for auto-sensing 10/100Mbps Ethernet, Token Ring, mixed Ethernet and Token Ring
environments
DC and AC Power Supply
Options
• Allows deployment in DC powerenvironments such as telecommunications carrier central offices or
as a managed Customer Premise Equipment (CPE) platform with an AC power supply
Service Provider/Carrier DCN-Class Performance
High-Performance
Architecture
• RISC processor based to support high-speed routing performance of up to 37,000 packets per
second for maximum scalability to support more concurrent functions (Cisco 2650 and Cisco 2651)
per second for maximum scalability
• Support for advanced QoS features such as the Resource Reservation Protocol (RSVP), Weighted
Fair Queuing (WFQ), and IP Precedence to reduce recurring WAN costs
• Support for up to 8 T1/E1 network connections
• Up to 36 asynchronous or 12 synchronous connections are supported in a single Cisco 2600
enabling telemetry applications
• Support for TDM traffic with drop and insert capability
• AIM slot support to off-load processor intensive applications including hardware-based
compression, encryption, and ATM access.
• Enables security features such as data encryption, tunneling, and user authentication and
authorization for virtual private network (VPN) access
• Full Cisco IOS
®
Software Support
Deployed in IP networks
around the world, the Cisco
IOS software supports the
following DCN related
services:
• Full IP Routing Services including multiprotocol BGP, multi-Area ISIS and DNS
• TL1 support including transport via X.25, TCP or OSI. TID Address Resolution Protocol (TARP)
support and TARP Storm Avoidance support.
• PPP services including WAN interface support for ISDN, Frame Relay, ATM, and X.25
• X.25 support services including X.25 switching, X.3 Asynchronous PAD, DNS for X.25 address
resolution, Hunt Groups, and SVC/PVC conversion
• IP to X.25 Protocol Translation
• BX.25 Transport over X.25 or TCP (XOT)
• Support for up to 3 OSI/IS-IS areas, per chassis, essentially providing the same capabilities as 3
separate OSI routers.
• Full-featured IP and OSI routing and mediation on a single platform, including legacy X.25, and async
devices support ICSA-certified Cisco IOS Firewall feature sets provide support for advanced security
features such as Context-Based Access Control (CBAC), Java blocking, denial of service protection,
and audit trails
• Integration of legacy networks via data link switching plus (DLSW+) and Advanced Peer-to-Peer
Networking (APPN)
Simplified Management
Common Language
Equipment Identification
(CLEI) Codes
• Enables easy identification and tracking of central-office equipment
Part of the Cisco DCN
Stackable Solutions
• Can be stacked with LAN switches such as the Catalyst 1924DC or Cisco 3662-AC/DC-CO modular
access platform
VLAN Support • Enables inter-VLAN routing via the Cisco Inter-Switch Link (ISL) protocol with the Cisco Catalyst
1924DC and 2924M XL DC switches and the Cisco3662-AC/DC-CO when used with the Cisco 2620
and 2621 and Cisco IOS “Plus” feature set
