The AT Command Set
AT&B
–B
N
EARER
This command sets the units Bearer Capability. The options are:-
AT&B0 - sets the Bearer Capability to Digital Mode (data).
AT&B1 - sets the Bearer Capability to Speech Mode (3.1 kHz audio).
AT&B2 - sets the Bearer Capability to V.110 Mode (V.110).
The CyberGear sends the Bearer Capability Mode to the ISDN Switch when the unit
initiates an outgoing call. The Mode setting should mirror that set at the remote end of the
link.
AT&C
– DCD
N
BEHAVIOUR
This command controls the DCD output pin (pin8) on the CyberGear. There are three
choices; 0 - always ON, 1 – Normal and 2 – Pulse Disconnect.
AT&C0 - DCD always ON. The DCD output pin is always forced ON regardless of the
call state.
AT&C1 - Normal. DCD is in the OFF state until the CyberGear detects and establishes
incoming call.
AT&C2 - Pulse Disconnect. DCD is always forced ON except during the call disconnect
sequence, where it is pulsed OFF. The DCD OFF pulse time is controlled by
S10.
AT&D
– DTR
N
ACTION
This command is used to control the operation of the unit by monitoring the status of the
DTR input (pin 20) and act accordingly.
AT&D0 - The status of the DTR control signal is ignored.
AT&D1 - The number previously stored in the unit with the AT&A command is
automatically dialled when DTR control is asserted (set to the ON state).
AT&D2 - When the DTR control signal changes from the On to OFF state any call in
existence is dropped.
AT&D3 - When DTR changes from the ON to OFF state the call is dropped, if one exists,
and the unit is then reset.
AT&F
–D
N
EFAULT
Use the AT&Fn command to load configuration n with the Factory Default settings. If n is
omitted then the current configuration parameters are overwritten by the Factory Defaults.
i.e. AT&F1 -
forces the parameters stored in profile 1 to their Factory Default values.
AT&F -
the current configuration parameters are overwritten by their Factory
Defaults.
