7. Special applications

7.1

Dial-in configuration

The Proxima ISDN Lite can be set to link a telephone number to a protocol. When this number is called, the Proxima ISDN Lite
will establish a connection according to the set protocol. When this number is called, this call is always passed on to the
analog connection.
Subaddresses and Multiple Subscriber Numbers can be linked to protocols with special AT commands. The general
construction of AT commands is described in chapter 3.3.
7.1.1

Subaddresses

Subaddressing consists of adding an extra character (with a maximum of four characters) to the telephone number. These
extra characters are passed on to the ISDN device that is called. When using the Proxima ISDN Lite, a caller can, for instance,
select a protocol (i.e. remote) by giving a subaddress. Conversely, the Proxima ISDN Lite can dial a number and add extra
characters to the telephone number. This is limited to ISDN equipment. The subaddress service is not a standard feature and
needs to be applied for.
The table given below gives the AT commands for the various types needed to change the default link between protocol and
subaddress. The link is switched off by not entering a value (empty string).
Syntax Value
#SAPPP 4 digits
#SAV120 4 digits
#SA2B 4 digits
#SARTEL 4 digits
#SARDATA 4 digits
#SAMPPP 4 digits
Examples of subaddresses:
a. programming:
AT#SAPPP=28<ENTER>
AT#Z<ENTER>
Calling your own ISDN number and adding 28 as extra numbers will make the terminal adapter create a PPP connection.
b. switching off link:
AT#SAPPP=<ENTER>
AT#Z<ENTER>
The link between the PPP protocol and the subnumber is disconnected.
c. dialing:
A subaddress is added to the dial command as follows:
ATD010-1234567*28<ENTER>
Dial 010-1234567 and add subaddress 28.
