The information S ₁ of the layer 1 is classified into INFO signals having the meanings shown in Table 1.

[Table 1]

The INFO signal shown in Table 1 is used for starting layer 1 as described later.

The information S ₂ used in the layer 2 has a higher frame format than the signal S _{1 of the} layer 1, and the main frame type and the contents of the information S ₂ of the layer 2 are described in the second. These are summarized in the table.

[Table 2]

In Table 2, the user information in the information transfer frame (I frame) is transmitted through the B channel, but the I frame for call control and the unnumbered frame (U frame) are respectively transmitted in the D channel. Is transmitted via
The SABME command of the U frame is used to set the data link between the terminal device and the network side to a multiframe confirmation type operation mode, which is a number-based information transfer frame in Layer 2. This is an operation mode in which one frame is transmitted in numerical order, and when a transmission error occurs, retransmission is performed for recovery. The DISC command is then used to terminate the multi-frame acknowledged mode of operation.

Further, the call control signal of the D channel of the information S ₃ used in the layer 3 are classified into the following message, each of these messages for realizing circuit switching and packet switching in B channel Used for setting the B channel link.

(1) Call setup message The call setup message contains the calling number (telephone number, etc.), called number, relay network selection information, transmission capability information, etc., and is used for a call setup request. (2) Call setting reception message This message is used to notify that all the call setting information has been received. (3) Response message Used to notify the calling side that the called side has accepted the call. (4) Disconnect message Used for a request to disconnect the connection between terminal devices. (5) Release message This is used for a release request of the information channel or the like after the disconnection of the information channel (B channel). (6) Release completion message Used for notification of release of an information channel or the like.

When transmitting B-channel information from a terminal device (TE) to another terminal device via a network (ISDN) using the above-mentioned information of layers 1 to 3, the terminal device on the transmitting side thereof The communication operation with the network will be described with reference to FIG. First, in step 101, for example, when the receiver of the terminal device is taken off-hook by the operator, the terminal device transmits a layer 1 <INFO1> signal (see Table 1) to the network side. <INFO2> signal is returned. Then, in step 103, the terminal device sends the <INFO
3> When the signal is transmitted, a layer 2 activation display request signal is sent to the network side. In step 104, the network transmits an <INFO4> signal to the terminal device side to establish a layer 1 link, and Layer 2 starts.

Next, the terminal device receives a dial setting request of the layer 3 for dial setting the called number which is the number of the receiving side, and in step 105, the SA of the layer 2 is received.
In response to the transmission of the BME command (see Table 2) to the network side, the network responds to the dialing indication, which is an advance notice of the dialing setting, to the circuit system corresponding to the layer 3 of the network. The UA command is transmitted to the device. As a result, dial setting confirmation indicating that dial setting is possible in a circuit system corresponding to layer 3 of the terminal device is performed, and a link of layer 2 is established. In layer 2, one frame is transmitted in the multi-frame confirmation type operation mode. Transmission becomes possible, and layer 3 is activated.

Next, in step 107, the terminal device transmits a call setup message of the layer 3 including the calling number and the called number to the network side in response to the dialing of the called number by the operator. The call setup message and the like are transmitted in a layer 2 information transfer frame (I frame). Upon completion of the reception of the layer 3 call setup message, the network transmits a layer 3 call setup acceptance message to the terminal device in step 108. Then, when the called number has a vacancy and the receiving side accepts the call, the network transmits a layer 3 response message to the terminal device side (step 109), and the layer 3 information transmission on the B channel becomes possible.

Subsequently, after information transmission on the B channel is completed in step 110, for example, when the operator turns on the receiver, in step 111, the terminal device transmits a layer 3 disconnection message to the network side. When the layer 3 release message is transmitted from the network to the terminal device (step 112), the terminal device transmits the layer 3 release message to the network side.
Is transmitted (step 113).
The used B channel is released.

In response to the dial release request from the circuit system corresponding to layer 3 of the terminal device, the terminal device transmits a layer 2 DISC command (see Table 2) to the network side in step 114, and Transmits the UA command to the terminal device (step 115), thereby terminating the multi-frame confirmation type operation mode in layer 2. next,
In step 116, the network side transmits a layer 1 <INFO0> signal indicating a no signal state to the terminal apparatus, and in response thereto, the terminal apparatus in step 117 indicates a layer 1 <INFO0> indicating a no signal state to the network side. The communication operation is completed by transmitting the signal.

In the operation shown in FIG. 6, steps 105 to 109 and steps 111 to 115 are respectively performed by the D for transmitting the call control signal.
The transmission is performed via a channel, and the transmission of step 110 is performed via a B channel for information transmission.
