This feature can be used with IVR's, Procentre and as below a fax server.
This is an example of a site were the BRAIF extension is 5406 and the fax server is connected to the BRAIF S-Bus as EUROISDN, ( not UKISDN ).
The supplementary digits are going to be four digits long, SPNSD, and will use the I/C DDI digits 5201, 5202, 5203 and all numbers beginning 53.
The I/C DDI trunk main group uses digit translation table 04, LTMG. In table 04 the above digits are translated with a prefix of *#185406, this is the DDI digit ACD feature and the S-Bus extension number. This causes the I/C DDI digits to be sent to the fax server and thus routing to a particular fax machine.
Note CSTA must be turned on in the feature table.
System parameter SPNSD = Max number of supplementary digits allowed for ACD/CSTA DDI digit feature.
System parameter TMASD = Timeout period between receipt of supplementary digits for ACD/CSTA DDI digit feature.

5201 *#1854065201
5202 *#1854065202
5203 *#1855065203
53 *#18540653
*#18 feature instructs the DX to direct calls to the identifiable number (5406)
When the call is presented to the fax server (5406), the additional digits i.e “5201” are passed to fax server to route to a particular fax machine.
Hope this helps.
