+D Ba5ic Access method or 23B+D
In the Primary Access method, communication is performed with the communication partner terminal via a terminal adapter that is located between the B channel and the communication partner terminal and matches the B channel data to a communication speed corresponding to the communication speed of the communication partner terminal. In the communication control device, in response to a call request from a host device and a re-call request given each time the call is incomplete, the address and terminal speed information of the communication partner terminal are included in the call data and sent via the D channel. and a D channel control unit that makes a call to the communication partner terminal, and when there is an indication of an incomplete call in the D channel data sent from the terminal adapter of the communication partner terminal in response to the call origination data. Recognizing the reason for an incomplete call, which is activated by the D channel control unit and outputs the re-call request and the terminal speed information update instruction when the cause of the incomplete call is a mismatch between the sent terminal speed information and the destination terminal speed. and a B channel communication speed matching section that sequentially selects one of the plurality of terminal speed information prepared in advance and outputs it to the D channel control section each time the terminal speed information update instruction is received.

終的には呼設定が可能となる。When the D channel control unit 11 receives D channel data from the terminal adapter 102 of the partner terminal 103, the non-completion reason recognition unit 12 receives the non-completion reason data 53 included in the received D channel data and the reason for non-completion is speed mismatch. When it recognizes that it is, it issues a speed information update instruction 51 to the B channel communication speed matching section 10, selects it from among the plurality of known speed information it has in advance, and outputs it to the D channel control section 11. At the same time, a re-calling instruction 52 is issued to the D channel control unit 11. As a result, the D channel control unit 11 repeatedly makes calls using the speed information of various terminals, searches for the speed of the other party's terminal 103, and finally becomes able to set up a call.
