Cisco Secure Router 520 ADSL-over-ISDN Routers

The Cisco Secure Router 520 ADSL-over-ISDN router is a routing device that uses an asymmetric digital subscriber line (ADSL) over integrated services digital network (ISDN). These routers have an integrated 4-port Fast Ethernet switch for connecting to the LAN and an ADSL-over-ISDN physical interface for connecting to the WAN. This feature allows the router to connect a small business or a teleworker to a central office or an Internet service provider (ISP) over an ADSL interface.

Two router models are available:

•Cisco Secure Router 520 ADSL-over-ISDN (without wireless functionality).

•Cisco Secure Router 520 ADSL-over-ISDN Wireless (with wireless functionality). The wireless router supports the use of a single 2.4-GHz antenna.
