Default

 

Description

 

 

 

 

 

Modulation Automode Control: This command specifies the alternative to the preferred modulation

 

 

specified in the +MS=<carrier> command. Alternative modulations are only available when

 

 

+MS=,<automode> enables automode. The alternative modulations available for the +MA command are

 

 

limited to all modulations the modem supports below the preferred modulation specified by

 

 

+MS=<carrier>. The +MA parameters are reset to all modulations supported by the modem below the

 

 

preferred modulation whenever the +MS=<carrier> changes the preferred modulation. The order of

 

 

priority of alternative modulations is determined by such mechanisms as V.8 and PN2330, not the order

 

 

in which they were entered for this command. <carrier> values omitted are no available as alternative

 

 

modulations.

 

 

m= <carrier>,<carrier>,…<carrier>

+MA=m

none

Defaults: all modulations below +MS=<carrier> and allowed by the DCE limits in the +MS command

 

 

<carrier> specifies the alternative modulations that are available. A table of these modulations are given

 

 

in +MS command description.

 

 

+MA? will display a list of enabled alternative modulations

 

 

+MA=? will display a list of available alternative modulations. This list is determined by the current values

 

 

of the +MS parameters for preferred modulation, automode and DTE rate limits. For example:

 

 

 

If +MS=<V32B>, V.34, V.90, and V.92 will not be available because they are above V.32 bis.

 

 

 

If +MS = ,0,, no alternative modulations will be available.

 

 

 

If +MS=V34,1,4800,33600, V.22 bis will not be available because its maximum DCE bit rate is

 

 

 

2400bps.

 

 

 

 

 

Modulation Reporting Control: Controls whether the “+MCR: and +MRR” result codes are transmitted

 

 

from the DCE to the DTE once a connection has been made. If enabled the result code displayed shall

 

 

represent the current negotiated DCE-DCE modulation and rate, and are issued before the Error Control

 

 

(+ER:) or Data Compression reports (+DR:) and before the final result code “CONNECT”. The format is

 

 

as follows:

+MR=m

0

0

Disables reporting of modulation (no +MCR and +MRR intermediate result code

 

transmitted)

 

 

 

 

 

1

Enables reporting of modulation (+MCR and +MRR intermediate result code transmitted)

 

 

Example if +MR = 1

 

 

+MCR: V34

 

 

+MRR: 33600
