4. HIGHSPEED AT-COMMANDS
On the table below it is described AT-commands for Modem, ISDN v.110 and ISDN v.120
connections with different channel coding (speed of each slot) and timeslots (number of
receiving/transmitting slots). For example 3+1, 28800, 9600 means that the maximum speed
that you can receive data is 3x9600=28800 and maximum speed for sending data is
1x9600=9600, the maximum connection speed that is shown in the task tray is the same as
the maximum sending speed (28800).
