DV_TPT — termination parameter table
• If tp_termno contains DX_PMON, tp_data can specify the maximum time of silence on.
• If tp_termno contains DX_TONEOFF, tp_data can specify termination after a tone-off
event.
• If tp_termno contains DX_TONEON, tp_data can specify termination after a tone-on
event.
tp_nextp
Points to the next DV_TPT structure in a linked list if the tp_type field is set to IO_LINK.
Table 16 indicates how DV_TPT fields should be filled. In the table, the tp_flags column describes
the effect of the field when set to one and not set to one. “*” indicates the default value for each bit.
The default defines for the tp_flags field are listed in the description of the tp_flags, above. To
override defaults, set the bits in tp_flags individually, as required.
