SUPPLEMENTARY SERVICE
SUBADDRESSING (SUB)
DEFINITION

delivered unaffected to the called (served) user. Only
the served user defines the significance of the
subaddress.
Subaddressing in ASB 150 02 is only applicable for the
ISDN terminals on the S-Interface and depends on
their individual programming.

function on the called ISDN terminal or to transmit a
