Overview

Overview

T.30 is a fax handshake protocol that describes the overall procedure for establishing and managing communication between two fax devices.

T.30 covers these five phases of a faxing:

1. Setup the Call

2. Select the Communication Mode

3. Transmit the Message

4. Post Message Processing (Including End-of-Message and Confirmation)

5. Release Call / Disconnect

Note: T.30 does not allow for data transmission or processing. T.30 allows only for the transfer of fax image standards T.4 and T.6.

For more information about the Group 3 fax standard, see ITU T30 Fax standard.
