Digital Modem Applications

Historically, branch office connectivity has been synonymous with connecting the local LAN to a regional or central site. With the rapid growth in mobile computing and telecommuting, more and more branch offices need to add user-to-LAN capabilities.

Using ISDN PRI, ISDN BRI or Fast Ethernet/ISDN PRI, and digital modem network modules, the Cisco 3600 provides the ideal functionality for the branch and enterprise offices.

Figure 1 illustrates a typical application for the ISDN PRI and digital modem network modules.

For basic telephone users, both 33.6K and 56K modem calls can be terminated through a PRI/BRI connection into a digital modem network module, including mobile workers and people working from hotel rooms. For teleworkers with access to Basic Rate Interface (BRI), the same phone number could be used to connect to the same Cisco 3600, achieving 64 kbps non-compressed, or with multilink PPP, 128 kbps.

Multiple backhaul options are available to link back to

a corporate network, at speeds up to 8 Mbps. Additionally, a slower speed (T1 or Frame Relay, for example) connection could link the branch to the World Wide Web.
