t38_terminal_front_end_state_t Struct Reference

## Public Attributes

int | iaf
| Internet Aware FAX mode bit mask.
int | us_per_tx_chunk
| Required time between T.38 transmissions, in microseconds.
int | chunking_modes
| Bit fields controlling the way data is packed into chunked for transmission.
t38_core_state_t | t38
| Core T.38 IFP support.
int | timed_step
| The current transmit step being timed.
int | queued_timed_step
| The timed step to go to when we reach idle from the current timed step.
int | rx_data_missing
| TRUE is there has been some T.38 data missed (i.e. lost packets) in the current reception period.
int | octets_per_data_packet
| The number of octets to send in each image packet (non-ECM or ECM) at the current rate and the current specified packet interval.
struct { |
uint8_t buf [T38_MAX_HDLC_LEN] |
| HDLC receive buffer.
int len |
| The length of the contents of the HDLC receive buffer.
} | hdlc_rx
struct { |
uint8_t buf [T38_MAX_HDLC_LEN] |
| HDLC transmit buffer.
int len |
| The length of the contents of the HDLC transmit buffer.
int ptr |
| Current pointer within the contents of the HDLC transmit buffer.
int extra_bits |
| The number of extra bits in a fully stuffed version of the contents of the HDLC transmit buffer. This is needed to accurately estimate the playout time for this frame, through an analogue modem.
} | hdlc_tx
int | non_ecm_trailer_bytes
| Counter for trailing non-ECM bytes, used to flush out the far end's modem.
int | next_tx_indicator
| The next T.38 indicator queued for transmission.
int | current_tx_data_type
| The current T.38 data type being transmitted.
int | rx_signal_present
| TRUE if a carrier is present. Otherwise FALSE.
int | current_rx_type
| The current operating mode of the receiver.
int | current_tx_type
| The current operating mode of the transmitter.
int | tx_bit_rate
| Current transmission bit rate.
int32_t | samples
| A "sample" count, used to time events.
int32_t | next_tx_samples
| The value for samples at the next transmission point.
int32_t | timeout_tx_samples
| The current transmit timeout.
int32_t | timeout_rx_samples
| The current receive timeout.
