Figure 5 ISDN LAN Modem Single Workstation Connection Example
An ISDN BRI line has two B channels for transmitting data or voice. Because each
B channel is independent, you can connect to two different locations. Once the
connection is established, up to 25 users can share either connection. Figure 6
shows one user connecting to a remote office LAN while another connects to the
Internet.
