7-2 Advanced ISDN
Control of Outgoing Service Indicator
The high-layer compatibility and low-layer compatibility information provides a means for
compatibility checking by the called party. This information is transferred transparently by the
ISDN network between the call-originating entity (for example, the calling user) and the addressed
entity.
The outgoing high-layer compatibility can be controlled by setting the value of S-register
S(108+n) as follows:
• n=0 (S108) setting for analog adapter 2
• n=2 (S110) setting for ISDN data calls
• n=3 (S111) setting for analog adapter 1
Table 7-1 lists the S-register values and their functions.
Example: ATS111=4 sets fax compatibility message for analog port 1.
