Circuit-switched data calls

A circuit-switched data call can be established between two data terminals over a B-channel.
The call is set up the same way as a voice call. Dial a call using the ISDN BRI terminal key
pad or keyboard, depending on the type of ISDN BRI terminal used. After the connection is
established and the called ISDN BRI terminal sends an acknowledgment that it is ready to
receive data, the call-originating ISDN BRI terminal can start transmitting user data.
If the call-originating ISDN BRI terminal requests access to data stored in another ISDN BRI
or non-ISDN BRI terminal, it may have to provide a password to be able to access that data.
Note:
Follow the instructions in the ISDN BRI terminal user manual for a detailed description of
how to set up a call connection and how to transmit and receive data.
In general, data terminals are divided into the following categories:
• intelligent terminals, such as personal computers
• dumb terminals such as video display terminals
Repeat this test on several terminals, including both intelligent and dumb terminals as
needed.
