Second dial tone after digits
Sometimes it's useful to provide a second dial tone, after a dialed digit sequence or access code. This is achieved with the Special Dial Tone After Dialed Number (DTAD), and Flexible Tones and Cadences (FTC) data blocks - both in LD 56.
1Make sure DLTN is off, as it over-rides DTAD: LD 86, FEAT ESN, DLTN NO (default is YES)
2Define the digit pattern in LD 56 DTAD: Special Dial Tone After Dialed Number data block
REQ new TYPE dtad DDGT 9 dialed digits (1-5 digits) TONE src1 tone source after these digits DDGT hit return to finish
3Define the source tone in LD 56 FTC: Flexible Tones and Cadences data block
REQ chg TYPE ftc TABL 0 FTC table number (0-32) SRC yes SRC1 XTON 68 68 in ZA, 175 in D, 4 in NA XCAD 0 SRC2 hit return until finished
In this example, after digit 9 is dialed, source tone 1 is heard. Eight 'sources' (SRC1 thru 8) can be defined in each FTC table.
I'm not sure what all the XTON country tones are, but 68 is South African, 175 German, and 4 (default) is North American dial tone.
An FTC table number (0-31) can be entered for each trunk route at prompt TTBL in LD16. Table 0 is the default for all trunk routes and contains the default tones and cadences for North America. The FTC feature is mainly intended for international markets which require localised tones.
