Configuring T.30 Fax

Feature Description

See T.30 Fax.

Configuration

1. Use the DSP SIMM Configure 0x00C0 message to assign T.30 Fax Function Type to the DSP.

2. Configure T.30 FAX parameters using FAX TLVs in the Generic Card Configure 0x0122 message.

3. Use the Resource Connect 0x0127 message to initiate a fax.

Resource Type TLV: Send FAX (0x0105) or Receive FAX (0x106)

Page Range in TIFF File

This feature allows the user of the DSP2’s Fax transmission capability to select a range of pages for transmission out of a single TIFF file. This allows you to incorporate selective page transmissions into your application for such reasons as removal of cover pages for fax store and forward applications or fax back services which send selective sections of repair manuals.

To use this feature, send the Resource Connect 0x0127 message with the 0x068C FAX Page Range TLV.
