Command Default

Description

V.8 and V.8 bis Operation Controls: This command configures V.8 and V.8 bis operation. If issued when the DCE is on-hook, this command is a compound parameter used to precondition V.8 and V.8 bis originating and answering operation. It is not supported as an action command while the DCE is off-hook. If enabled, V.8 negotiation does not preclude simultaneous implementation of other means of negotiation (for example, V.8 bis, V.18, and V.32 bis Annex A).

For the +A8E default values, the signal indicators are not generated by the DCE. When the parameters <v8o>=6 and <v8a>=5, the +A8I, +A8C, +A8A, +A8J, and +A8M indications are sent from the DTE, but the +A8M command is not used because the DCE controls the V.8 section.

Indication

Definition

+A8A:1

+A8A:2

Indicates V.8 ANSam has been detected. This indication is only sent to the DTE if +A8E<v8o>=6 and operating in originate mode.

Indicates V.25 answer tone (2100 Hz) has been detected. This indication is only sent to the DTE if +A8E<v8o>=6 and operating in originate mode.

+A8I:<v8cf> Indicates the detection of a V.8 CI-signal and the recovered call function (only if +A8E<v8a>=5 and operating in answer mode).

+A8M:<CM>Indicates the hexadecimal-coded CM signal (only if +A8E<v8a>=5 and operating in answer mode)

+A8M:<JM> Indicates the hexadecimal-coded JM signal (only if +A8E<v8o>=6 and operating in originate mode)

Indicates the modem is transmitting the V.8 termination signal. +A8J:1 indicates +A8J:[0,1] transmission or detection of CJ while +A8J:0 indicates time-out while waiting for a CJ

signal.

NOTE: An asterisk (*) denotes the factory-default setting.
