AT!D3 =n Default Parity. Specifies the parity to be used, when the DTE characteristics cannot
be determined by AutoBauding (AT has not been typed since power up).
n=0 None (default).
n=1 Even.
n=2 Odd.
AT!D4 =n Default Stopbits. Specifies the number of Stopbits to be used, when the DTE
characteristics cannot be determined by AutoBauding (AT has not been typed since
power up).
Values: 1, 2.
Default:1
AT!Ln Set ISDN Encoding Law. Specifies the type of encoding law for ISDN voice calls.
n=0 If the switch type is EuroISDN or TPH, A law will be used; if the switch type is
INS-Net64, NI-1, or 5ESS, µ law will be used (default ).
n=1 µ law.
n=2 A law.
Note: This parameter does not take effect until you restart your DIVAT/A.
AT!N 1=n ISDN Directory Number Assignments for 1st B-channel and 1st Phone port. This
command assigns one ISDN directory number to the 1st B-channel and up to two
numbers to the 1st Phone port. The 1st B-channel only responds to the first number
specified in the command, while the 1st Phone port responds to either number.
Numbers are separated by a semicolon (;).
Example: Sending the command AT!N1=5551234;5551235 to the DIVAT/A
assigns the number 5551234 to the 1st B-c hannel, and the numbers 5551234 and
5551235 to the 1st Phone port. If a data c all is placed to 5551234, the 1st B-chann el
will answer. If a data call is placed to 5551235, the 1st B-channel will not answer.
However, the 1st Phone port will answer analog calls placed to either number.
For outgoing calls, both data and analog, the DIVAT/A uses the first of these two
numbers to ide ntify itse lf.
Note: In North America, you may only assign one number to the phone port.
Valid digits: 0-9, *, and #. Maximum: 20 (North America), 40 (International).
Default: null string.
Note: This parameter does not take effect until you restart your DIVAT/A.
