This feature permits individual storing of a maximum of 10, 20, or 30 arbitrary digit sequences, each comprising up to 22 digits, at any ANATE or DIGITE, but not at the attendant terminal. Destinations are stored in a memory which is set up with the AMOs SCSU/SBCSU/SSCSU, by declaring parameter SPDI=0, 10, 20, or 30 when the port is assigned (action ADD) or the number of SPDI is increased/decreased for an existing port (action CHANGE).

Destinations are entered either at the service terminal with the ZIEL AMO or at the user's telephone by means of a dialing procedure.
