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.

  • Page 25 Interface configuration Usage Guidelines This command first appeared in Cisco IOS Release 11.1. It became available for BRI interfaces in Cisco IOS Release 12.0(2)XC and Cisco IOS Release 12.0(3)T. Unless you specify otherwise, all calls received by the router and characterized as voice calls are treated as normal ISDN calls, which are handled as digital data and not passed over to the modem.
  • Page 26 Command Mode Interface configuration Usage Guidelines This command first appeared in Cisco IOS Release 11.1 when it was available for PRI interfaces. It became available for BRI interfaces in Cisco IOS Release 12.0(2)XC and Cisco IOS Release 12.0(3)T. Using this command distinguishes call errors due to busy modems from other call errors (for instance, busy B channels) that might return the same ISDN default error code of 21.
