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.

<rate> Value Downstream Rate <rate> Value Downstream Rate

0 V.90 disabled. 12 41333 kbits/s.

1 Auto rate (default). 13 42666 kbits/s.

2 28000 kbits/s. 14 44000 kbits/s.

3 29333 kbits/s. 15 45333 kbits/s.

4 30666 kbits/s. 16 46666 kbits/s.

5 32000 kbits/s. 17 48000 kbits/s.

6 33333 kbits/s. 18 49333 kbits/s.

7 34666 kbits/s. 19 50666 kbits/s.

8 36000 kbits/s. 20 52000 kbits/s.

9 37333 kbits/s. 21 53333 kbits/s.

10 38666 kbits/s. 22 54666 kbits/s.
