A telecommunications system and method for use on aircraft and other vehicles. One or more token ring local area networks are utilized to provide a telecommunications link between a plurality of telephone units and a telephone data signal router circuit which, in turn, is coupled to a CEPT E1 bus and provides telecommunications data signals over the CEPT E1 bus to a cabin telecommunications unit.
