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.
Procedure 36
Perform a circuit-switched data call test
1 From an ISDN BRI data terminal, dial another ISDN BRI data terminal
and establish an active call connection.
2 After receiving an acknowledgment that the other terminal is ready,
begin transmitting data.
