AD2 terminal interface
Two system terminals or one system terminal and a Pocket Adapter can be con-
nected in parallel to an AD2 terminal interface. Address allocation is done by
means of a switch on the terminal.
One DECT radio unit can be connected for each AD2 interface. An SB-8 radio unit
with 8 call channels occupies two AD2 interfaces.
