having a data message to transmit, to a polling signal made to
the group to which the data terminal is mapped;

data terminals within a terminal group attempt to transmit
data messages in response to a given polling signal;
wherein each data terminal maintains a count of the
number of unsuccessful attempts it has made for each data
message transmission and transmits this count to the terminal
mapping means when each data message transmission is
successfully completed; and
