Select modulation, Parameter
"a" specifies the modulation
protocol desired; where:0=
V.21, 1=V.22, 2=V.22bis, 3=
V.23,9=V.32,10=V.32bis,11
=V.34, ** 56=K56flex 64=Bell
103 and 69=Bell 212.
Parameter
"b" specifies automode oper
ations, where: 0=automode
disabled,1=automode enabled
with V.8, or V.32 Annex A.
Parameter "c"
specifies the minimum
connection data rate (300
-56000** or 33600). Para-
meter "d" specifies the
maximum connection
data rate (300-56000** or
33600). ** Parameter "e"
specifies the code type for
56K, where: 0=µ-Law. 1=A-
Law. ** Parameter "f" specifies
the control of robbed bit
signaling for 56K, where
0=Disables robbed bit
signaling generation or
detection. 1=Enables robbed
bit signaling generation or
detection. a,b,c,d,e,f,
