CareTaker Publications: Solution

• Using the Cisco Reseller Product Selection Tool, the following products were selected:

 
• Cisco 1602
• Cisco 1605
• Cisco 2524
• Cisco 2525

 
• Recommend the Cisco 2524 because it contains a built-in DSU and offers modular WAN connectivity.

• Using the Cisco Reseller Product Selection Tool, the following products were selected:

 
• Cisco 3620
• Cisco 3640
• Cisco 4500
• Cisco 4700

 
• Recommend the Cisco 3640 because it provides two high-speed (T1/E1) ports and provides future expandability. Cisco IOS software will address any new protocol requirements, and the plug-in network modules provide a high-performance RISC processor.

• Through the employment of Cisco's Ethernet switching technology, peak performance will be achieved for all user nodes on the network. This performance is accomplished by combining minimized user nodes on segmented dedicated 100-Mbps paths to servers. On average, each user should see virtually the full 10-Mbps path between the user and a given server.

 
• The TN3270 users are also given a dedicated port to the ES9000.

 
• The network design is simple and easy to manage for CareTaker's inexperienced administrators. It is a single-protocol, logically flat network. The naming and addressing is simple and easy to understand and track. The central location of all shared networking devices, servers, routers, switches, and so on, makes for easy administration and maintenance.

• Load-sharing CSUs are available from Adtran, Inc. and ADC Kentrox. The Open Connect gateway could be the Open Connect Server OC/3030 from Open Connect Systems.
