Multiple Subscriber Numbering
Specifying an Exclusive Data Port Directory Number
A specific number can be assigned exclusively to the data ports via the ‘Data’ tab. Click on the option ‘Configure a unique number to use for data calls’, then enter the number. The data port will answer only on that directory number, ignoring all other assignments.
If you enable this option, the data port will answer to this number only
You can also use the AT command AT!N5 to set this parameter (see the DIVA T/A Reference Guide for more information).
