Chapter 2 Using BIPAC-2AB 2.0
Keypad
Some telephone companies’ ISDN systems are using “Keypad Protocol” for activating/deactivating some supplementary services, such as external call forwarding. To let the ISDN a/b adaptor enter “Keypad” mode, you can press:
*00
Then, all the following keys and numbers will be sent out using “Keypad Protocol”.
Example: If your telephone company give you a keypad command of *21*number# to activate the external call forwarding function, you can press:
*00*21*number#
to send out *21*number# with “Keypad Protocol”. After the keypad command is sent out, all the incoming calls will be forwarded to the number.
