Abstract

PURPOSE:To attain reset without incurring a busy network by applying reset procedure after awaiting the next service request from an opposite station without transfer of positive reset procedure from its own station when reset is required for all logic channels. CONSTITUTION:When a fault is occurred in the communication of a data link level by a host computer system 1 and a gateway 2, it is required to reset all logic channels of a local area network 4 to prevent occurrence data missing. In this case, a data link establishing request 22 is sent to a service request 21 from an opposite station, the replying frame 23 is received and after a data link level is opened, the session is established. Thus, the concentration of traffics is avoided and reset is applied without giving any effect on the communication of other nodes.
