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

Step Action

1From an ISDN BRI data terminal, dial another ISDN BRI data terminal and establish an active call connection.

2After receiving an acknowledgment that the other terminal is ready, begin transmitting data.

3Verify that the transmitted data has been received successfully by checking transmitted information for accuracy. Read the information on the screen or print it on the local printer.

4Release the connection.
