V.90,V.34......, 64=Bell 103, and 69=Bell 212. Parameter ″b″ specifies automode
operations where: 0=automode disabled, 1= automode enabled with V.8/V.32 Annex
A. Parameter ″c″ specifies the minimum connection data rate (300- 56000). Parameter
″d″ specifies the maximum connection rate (300-56000); Parameter ″e″ specifies the
codec type (0= Law, and 1=A-Law). Parameter ″f″ specifies ″robbed bit″ signaling
detection (0=detection disabled 1=detection enabled)
