The Catalyst 4000/4500 Access Gateway Module is a modular Cisco IOS®, routing engine that integrates into the Catalyst 4000/4500 Series of switches. The Catalyst 4000/4500 Access Gateway Module provides WAN connectivity with the following features and benefits:
- Lower cost of ownership - Through consolidation of the LAN and WAN network infrastructures the complexity of the network is reducedsimplifying the ease of use and administration. Field support is also simplified as the Access Gateway Modules shares interface cards with the 1600/1700 and 2600/3600 router families.
- Improved productivity - Once a branch configuration template is developed an integrated solution for the branch office streamlines the deployment processmaking better use of deployment and operation resources. With the enterprise WAN in place earlier the business applications can be deployed throughout the enterprise.
- Investment protection - With full Cisco IOS support and a modular architecture, the Access Gateway Module provides IP WAN connectivity for the branch and a migration path to convergence. The Access Gateway Module provides full support for Cisco IOS IP routing with options for: voice PSTN and PBX connections for toll-bypass applications, and Digital Signal Processors for CallManager Voice Service and IP Telephony.
- Scalability and Performance - The modularity of the Catalyst 4000/4500 Access Gateway Module provides scalability in both voice and data interfaces and network services. Underpinning this scalability is a high performance RISC central processor and hardware based encryption and compression.
