Modem over ISDN BRI for the
Cisco 3640 Router
Feature Summary
The Modem over Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) feature for
the Cisco 3640 modular access router lowers the cost of remote access by offering high-speed
modem and ISDN connectivity for mobile customers, home-offices, and other remote-access users.
Branch offices and enterprises can support analog modem users who call over the public switched
telephone network (PSTN) into BRI interfaces in Cisco 3640 routers.
Analog modem calls arrive at a speed of 33.6 kilobits per second (kbps) via the PSTN. The router's
digital modems accept the modem calls at connection speeds as fast as 56 kbps, adhering to the V.90
standard. As shown in Figure 1, the Cisco 3640 router in this way provides rapid access to email and
other network services.
