3.2.7 V.8/V.8bis Commands
3.2.7.1 +A8E - V.8 and V.8bis Operation Controls
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).
This command 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. For
example, if initial V.8 negotiation failed, but subsequent T.30 negotiation indicated V.8 capability, this command may be used
to initiate V.8 negotiation.
Syntax

Defined Values

= Decimal number which enables/disables issuance of +A8x indications during modem-controlled
V.8 answer negotiation.
1 Enable DCE-controlled V.8 answer negotiation without +A8x indications. (Default.)
5 Enable DCE-controlled V.8 answer negotiation with +A8x indications.

< protrange >= ““. Applicable only for =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 =6 and =5, the +A8I indications are issued during the course of the V.8 session to
notify the DTE when the relevant V.8 signals are received.
