ABSTRACT:
A signaling path between a central office switch and a fixed radio access network terminal equipment supporting one or a plurality of subscriber handsets comprises a radio base station connection to the central office switch via a back haul transmission link, and communicates with the network terminal equipment via a wireless link operating in accordance with an air interface protocol e.g. such as described in International Standard Q931. In band service signals, e.g. of the Custom Local Area Special Services (CLASS) type, are issued by the central office switch on an in voice band channel and are stored at the radio base station whilst A party to B party call set up is effected over a digital signal path between the central office switch and the network terminal equipment. Out of band digital call set up signals and in band signals are multiplexed at the radio base station prior to transmission over digital channel of the air interface, thereby allowing call set up to occur before transmission of CLASS service signals to a subscriber handset.
