ABSTRACT:
In the case where calls made by a calling part of a first LAN connecting device are rejected by a call receiving part of a second LAN connecting device, non setting of the number of channels needed for data transmission will be detected by a channel shortage detecting block of the first LAN connecting device. In this case, an information requesting block will make a request for information of channel availability at the time of channel releasing to the second LAN connecting device. This request will be registered in the information request registering block of the second LAN connecting device. When availability of the channels accommodated in an interface is detected by the channel monitoring block of the second LAN connecting device, an information sending block will transmit channel availability information to the first LAN connecting device in accordance with the request registered in the information request registering block.
