Field Descriptions
On Dialogic ® DM3 boards, the fields of the CT_DEVINFO data structure are described as follows:
ct_prodid
Contains a valid product identification number for the device [length: 4 (unsigned long)].
ct_devfamily
Specifies the device family [length: 1 (unsigned char)]. Possible values are:
CT_DFDM3 – Dialogic ® DM3 device
CT_DFHMPDM3 – Dialogic ® Host Media Processing (HMP) device
ct_devmode
Specifies the device mode [length: 1 (unsigned char)] that is valid only for a Dialogic ® D/xx or
VFX/xx board. Possible values are:
CT_DMRESOURCE – Dialogic ® DM3 voice device in flexible routing configuration
CT_DMNETWORK – Dialogic ® DM3 network device or Dialogic ® DM3 voice device
in fixed routing configuration
For information about flexible routing and fixed routing, see the Dialogic ® Voice API
Programming Guide.
ct_nettype
Specifies the type of network interface for the device [length: 1 (unsigned char)]. Possible
values are:
CT_IPT – IP connectivity
CT_NTANALOG – analog interface. Analog and voice devices on board are handling call
processing
CT_NTT1 – T1 digital network interface
CT_NTE1 – E1 digital network interface
CT_NTMSI – MSI/SC station interface
