Cisco 1721 Modular Access Router. Powered by Cisco IOS, the cost effective Cisco 1721 (Cisco1721) provides WAN access optios, high-quality routing service, VLAN routing, and VPN access with firewall technology option.
The CISCO1721 is a solid modular router that has been designed with data access in mind, emphasizing speed and security. This device is refurbished. This translates to both cost savings and the quality of a Cisco router. As the manufacture states, the 1721 is “Optimized for data-access applications.” This router handles data flow superbly and uses a four-pronged attack to make it happen.

Flexibility: This CISCO1721 is a modular router. Modularity is the key to the strength of this design. Its three WAN interface card slots offer both comprehensive WAN support and easily permit as-needed changes to your network, without having to make massive changes to hardware that is already in place.

Security: The Cisco 1721 was made for VPNs. It has built-in support for 3DES IPSe and VPN encryption. Stack this onto Cisco’s IOS firewall and IDS software for Fort Knox-like data security. Like every Cisco 1700 series router, it also has an expansion slot that supports an optional hardware VPN encryption module that handles encryption with a RISC processor to provide up to T1/E1 data speeds.

Speed and Reliability: Cisco built the CISCO1721 with Business-class DSL in mind. It has WICs supporting both ADSL and G.SHDSS. This allows businesses to benefit from the cost effectiveness of DSL while employing several quality of service features to provide the performance required for both high priority and high bandwidth applications.

Control: Cisco’s IOS Software is fully supported in the CISCO1721. This software essentially sets the industry standard and provides the level of control to meet any business’s changing and growing needs. Aside from its security features, it also offers a full suite of controls for traffic management and prioritization.
