ISDN Configuration Commands
The following table describes the ISDN Configuration Commands.
AT!An
Directory Number/Port Assignment. This command specifies which ports answer
to which directory numbers. There are six ports available on the DIVA T/A: Phone 1,
Phone 2, Voice to PC 1, Voice to PC 2, Data 1, and Data 2.
Determining the value for n
Use the binary table below. If a bit is set to 0, the corresponding port answers
Directory Number 1. If set to 1, the corresponding port answers Directory Number 2.
Convert the binary to decimal and use the result in the AT!An command.
For example, to have Phone Port 1 and Data 1 answer to Directory Number 2 (and the
others to answer to Directory Number 1), create the binary form from the table
(100010), then convert to decimal (34). The command would be AT!A34.
Directory numbers are specified using the AT!N1 (for directory number 1) and AT!N2
(for directory number 2). A unique number can also be assigned to the data ports
using AT!N5. If AT!N5 is set, the assignments for the two data ports using the AT!An
command are ignored, but the Phone Port and Voice to PC assignments are kept.
Values for n:
A complete list of values for n is shown below. Ports are considered assigned to
Directory Number 1 unless specified as being assigned to Directory Number 2.
Abbreviations: Ph=Phone, VPC=Voice to PC, D=Data, DN=Directory Number.
