10.51.3.1. 4-digit speed dialing facility 
The abbreviated call number which is dialed must have 4 digits, of
which the first determines the central speed dialing list. This must
be reflected by the organization of these lists.
Example: The code for seizing the central speed dialing facility (*1)
must be dialed, followed by the abbreviated call number (2357).
Figure 111. Example for the 4-digit speed dialing facility
- Enable system with 4-digit speed dialing facility:
CHANGE-ZAND:TYPE=ALLDATA2,CSDZTYPE=4DIG;
- All stations wishing to use the 4-digit speed dialing facility must have entered group 0 under SPDC1 (e.g. AMO SCSU).
- Digit analysis results SPDC1 and SPDC2 must have been created in the digit analysis (AMO WABE).
- Central speed dialing lists 0 to 9 must have been created with the AMO LRNGZ. The
first
abbreviated call number in each list is 000, max. 1000 entries.
IMPORTANT:
Lists 0 to 9 must still be created if fewer than 10 lists are used, as otherwise the system will fail if the station dials a wrong number. The reason for this is that when a speed dialing list is dialed, the system always assumes that it actually exists. Any lists which are not required can remain empty, however. - Lists 1 - 16 can be assigned to speed dialing groups 1 - 16 if necessary. The lists are allowed to overlap, i.e. even if they are already being used for the 4-digit central speed dialing facility, lists 1 - 9 can still be used for speed dialing groups 1 - 9. Only a 3-digit number is dialed by these groups, however!
- Activating/deactivating the 4-digit speed dialing facility
The various features of the central speed dialing facility are switched on or off with the AMO ZAND. The normal speed dialing facility is activated in the initial state.In the branch TYPE = ALLDATA2 of the action 'CHANGE' the parameter CSDTYPE=4DIG must be set to activate the 4-digit CSD. The standard CSD is available with CSDTYPE=STANDARD.
