Table 3-48: -V90=<rate> Equivalent Downstream Rates
+A8E=<v8o>,<v8a>,<v8cf>,<v8b>—V.8 and V.8 bis Operation Controls
Use this command to set the control parameters for early call negotiation through
V.8 and V.8
bis . +A8E * may also be used as an action command to reinitiate V.8
or V.8 bis if an earlier attempt to use either protocol has failed.
<v8o> enables or disables DCE-controlled V.8 origination negotiation; <v8a>
enables or disables DCE-controlled
V.8 answer negotiation; <v8b> disables V.8 negotiation or sets it to DCE
controlled or DTE controlled negotiation. The <a8cf> parameter sets the V.8 CI
signal call function to the value specified. The valid range for this parameter is 0—
FF, with a default of 0xC1.
Result codes:
OK if <v8o> = 1, 6 and <v8a> = 1, 5 and <v8cf> = 0—FF and <v8b> = 0—2.
ERROR if <v8o> does not equal 1, 6 or <v8a> does not equal 1, 5 or <v8cf> does
not equal 0—FF or <v8b> does not equal 0—2. The following parameter values
are supported when V.80 is enabled.
