Additional Information
Manufacturer CISCO Manufacturer Part Number CISCO837-K9 SKU GROUP-128832 Ethernet Technology Fast Ethernet Flash Memory 12 MB Marketing Information - The Cisco 837 routers are asymmeric digital subscriber line (ADSL)-over-plain old telephone service (POTS) routing devices. They have an integrated 4-port Ethernet switch for the LAN and an ADSL physical interface for the WAN, allowing the routers to connect a corporate telecommuter or small office to corporate LANs and the Internet.
- The routers support high-speed encryption, the 10/100BASE-T switch, and dial backup functionality via the auxiliary console port. The autosensing function in these routers eliminates the need for a crossover cable and allows the router to detect medium dependent interface in normal mode (MDI) or medium dependent interface in crossover mode (MDIX) in any other PC or hub with a straight-through cable or a crossover cable. The routers are capable of bridging and multiprotocol routing between LAN and WAN ports.
- The dial backup feature allows the user to connect an analog modem to the console port as a backup link to the WAN in case the ADSL service goes down. This feature gives the Cisco 837 routers a high level of performance and security.
- The Cisco 837 router is designed with both hardware-based and software-based encryption.
