ABSTRACT:
A communication arrangement is disclosed which enables data calls between data terminals and a computer over a telephone network without significantly increasing the call blocking probability of the telephone network. When a data call, consisting of several data transactions is originated, the arrangement stores the called station information for later use in reestablishing a network connection on subsequent data calls between the same users. By disassociating the data terminal-computer data call signaling from the telephone network data call signaling, the telephone network is available for other data or voice traffic during the time when no data calls are active. A termination signal cancels the stored information and concludes the data call between the users.
