Bearer-Capability and Low-Layer-Compatibility information elements will be
determined when you configure the B channel protocols using the command ATBnn. The
outgoing Low-Layer-Compatibility information element can be turned on or off by setting
S80 bit 'n' as follows:
n = 4 for the analog adapter 2
n = 6 for ISDN data calls
n = 7 for the analog adapter 1
S80.n=0 Disable outgoing Low-Layer-Compatibility (default)
S80.n=1 Enable outgoing Low-Layer-Compatibility
Example: ATS80.4=0 disables Low-Layer-Compatibility message for Analog Port 2.
