Communication system comprising one or more exchanges and a number of
terminals (telephone sets, facsimile apparatuses, etc.) which each through
one of the mentioned exchanges is able to communicate with at least one of
the other terminals whereby a) the user of a calling terminal calls the
number of its own exchange, transmits signals indicating that the terminal
has to be called back by the exchange after which the connection is cut
off, b) thereafter the exchange establishes a connection with the calling
terminal, c) the user of the terminal transmits the number of a desired
other terminal to the exchange, d) the exchange thereafter establishes the
connection with the desired terminal, whereby at least the calling
terminals can be connected partly through wireless communication paths
with their own exchange and to comprise a buffer in which the number of
the desired other terminal can be stored, and comprise a circuit which,
after said number is keyed in by the user and is stored in the said
buffer, performs the above-mentioned steps a) instead of the user, waits
until the exchange reports again, retrieves the number from said buffer
and transmits this number instead of the user to the exchange which will
perform thereafter step d).
