Abstract: The invention provides a computer implemented system comprised of two computer terminals for effectuating bidirectional digital, time synchronized communications between networks operating asynchronously with respect to one another. The system repackages the data field of a message received from a network into a message that further includes time indicia corresponding to a time slot in which the repackaged message is to be transmitted so that it may be received by a second network. The repackaged message then is buffered until it is transmitted in the the appropriate time slot so that it may be detected by the second network. The invention overcomes the problem of effectuating communications between distant networks where the message propagation time and time slot period for receiving messages limits the range of communications.
