port_config=analog
Set the protocol file for T1 Robbed Bit using the callctrl.cfg
configuration file:
protocol_file=C:\Brooktrout\Boston\config\winkstart.lec
and for Analog, the protocol file is:
protocol_file=C:\Brooktrout\Boston\config\analog_loopstart_us.lec
Set the transfer_variant using the callctrl.cfg configuration
file:
transfer_variant=hookflash
The flash duration is set:
flash_hook_duration=50
Set the country code using the btcall.cfg configuration file:

Hookflash transfer is the only analog explicit call transfer method.
Using BSMI Applications
In T1 and analog BSMI applications, use L4L3mTX_HOOKFLASH
to set the duration of the hookflash signal. The field to set the signal
is:
L4_to_L3_struct.data.signal_duration_data = 0;
The duration of the hookflash signal is in milliseconds. The default
value is 0, which is equal to 500ms in duration. The maximum
setting is 64k.

Brooktrout Configuration Tool, refer to the
chapter on using the configuration tool in the installation and
configuration guide that came with your software.
