feature information — FEATURE_TABLE
• FT_ROUTEABLE – supports flexible routing configuration
For fixed routing, the FT_ROUTEABLE is not set, so none of the other bits is set. For flexible
routing, the FT_ROUTEABLE bit is set, and the other three bits are set based on cluster
contents.
For example, if the ft_front_end bitmask is FT_ROUTEABLE | FT_ISDN | FT_CAS, then the
channel is capable of flexible routing and can also work with an ISDN or a CAS (T1) frontend.
In this example, R2/MF is missing, so the channel cannot work with a front-end that is R2/MF
(E1 CAS) capable. As another example, FT_ROUTEABLE | FT_ISDN | FT_CAS | FT_R2MF
indicates support for flexible routing plus all three front-end capabilities, including R2/MF.
For more information on flexible and fixed routing configurations, see the Voice API
Programming Guide.
Note: On DM3 analog boards, use dx_getctinfo( ) rather than dx_getfeaturelist( ) to return
information about the type of front end or network interface on the board. The
network interface information is contained in the ct_nettype field of CT_DEVINFO.
On Springware boards, one or more of the following may be returned:
• FT_ANALOG – supports analog interface
• FT_EARTH_RECALL – supports earth recall
ft_misc
Contains a bitmask of miscellaneous features supported on the specified device.
• FT_CALLERID – supports caller ID
• FT_CSPEXTRATSLOT – reserves extra transmit time slot for continuous speech
processing
• FT_GAIN_AND_LAW – TDM ASIC supports AGC and law conversion
• FT_PROMPTEDREC – supports prompted record (triggered by VAD)
• FT_RECFLOWCONTROL – supports flow control on recording channels
• FT_VAD – supports voice activity detection
ft_send
Contains a bitmask of send fax features supported on the specified device.
• FT_SENDFAX_TXFILE_ASCII – indicates that ASCII file transfer is supported. If this
bit is turned off and the FT_FAX_EXT_TBL bit (in ft_fax) is turned on, then the device
supports DSP Fax (also known as Softfax).
• FT_TX14400 – supports fax transmission at 14.4 kbps
• FT_TXASCII – supports ASCII data fax transmission
• FT_TXFILEMR – supports MR encoded file format
• FT_TXFILEMMR – supports MMR encoded file format
• FT_TXLINEMR – supports MR encoded file format over the phone line
• FT_TXLINEMMR – supports MMR encoded file format over the phone line
• FT_TXECM – capable of fax line transmission with error correction mode
• FT_TXCCTFAX – supports the header “CCT FAX” when enabled in a download
parameter file
ft_receive
Contains a bitmask of receive fax features supported on the specified device.
• FT_RX14400 – supports fax reception at 14.4 kbps
• FT_RX12000 – supports fax reception at 12 kbps
• FT_RXFILEMR – supports MR encoded file format
• FT_RXFILEMMR – supports MMR encoded file format
• FT_RXLINEMR – supports MR encoded file format over the phone line
