Chapter 4 – V.8 / V.8bis Commands

V.8 is a way V.34 modems negotiate connections features and options, and V.8bis is a start-up sequence for multimedia modems.

Command: +A8E

V.8 and V.8bis Operation Controls

Description:

This command is defined for two conditions: as a parameter while the modem is on-hook,

 

and as an action command while the modem is off-hook. If enabled, V.8 negotiation does

 

not preclude simultaneous implementation of other negotiation means (e.g., V.8bis, V.18,

 

V.32bis Annex A). It is a compound parameter if issued while the modem is on-hook, used

 

to precondition V.8 and V.8bis originating and answering operation. It is issued by the

 

DTE before the Dial (D) or Answer (A) command, regardless of the state of the +FCLASS

 

parameter. This command is an action command if issued while the modem is off-hook to

 

(re)start V.8 or V.8bis negotiation.

 

Example: If initial V.8 negotiation fails, but subsequent T.30 negotiation indicates V.8

 

capability, this command may be used to initiate V.8 negotiation.

 

Syntax: +A8E=<v8o>,<v8a>,<v8cf>[,<v8b>][,<cfrange>][,<protrange>]

Values:

<v8o>

Decimal number which enables/disables issuance of +A8x indications

 

 

during modem-controlled V.8 origination negotiation.

 

 

1

Enable DCE-controlled V.8 origination negotiation without +A8x

 

 

 

indications. Default

 

 

6

Enable DCE-controlled V.8 origination negotiation with +A8x

 

 

 

indications.

<v8a>= Decimal number which enables/disables issuance of +A8x indications during modem-controlled V.8 answer negotiation.

1Enable DCE-controlled V.8 answer negotiation without +A8x indications. Default

5Enable DCE-controlled V.8 answer negotiation with +A8x indications.

<v8cf>= Set the V.8 CI signal call function to the hexadecimal octet XY

00Default

C1

 

<v8b>=

Decimal number which enables/disables V.8bis negotiation.

 

 

0

Disable V.8bis negotiation.

 

 

1

Enable V.8bis negotiation. Default

 

<cfrange>= “<string of values>“. Applicable only for <v8a>=5. Not supported.

 

< protrange >= <string of values>“. Applicable only for <v8a>=5. Not supported.

Default Values:

1,1,00,1,0,0

 

 

The ATD and ATA commands behave as specified in V.250, and +A8n indications are not

 

generated by the modem. For subparameter values <v8o>=6 and <v8a>=5, +A8I

 

indications are issued during the V.8session to notify the DTE when the relevant V.8

 

signals are received.

 

Report Commands:

+A8E?

Reports current or selected values.

 

+A8E=? Reports supported range of parameter values.

Command: +A8I

CI Signal Indication

Description:

This indication is issued by an answering modem, if +A8E,<v8a> .0, to indicate detection

 

of a V.8 CI signal and report the recovered Call Function octet(s).

 

Indication Syntax: +A8I:<v8cf><CR>

Values:

<v8cf>

A hexadecimal code octet representation of those Call Function octet(s).

 

 

+A8I:0 indicates that the modem timed out waiting for CI.

Example:

+A8I:0

The modem timed out waiting for CI.

 

+A8I:X
