see “m”

Distinctive Ring Selection: This command contains two parameters. The first
selects whether the modem reports distinctive ring cadence information. The
second parameter controls the timing of the RING event code report.

m=,
Defaults = 0, 0

Ring Reporting: The DCE reports the length of the ring period.

Range: = 0–255 (enables/disables distinctive ring reporting in the form
DROF=)

Time Ring Reporting: The DCE reports the silence period’s length.
The DCE may produce a RING event code after the DRON message if enabled
by the parameter. The parameter should be set to a value larg-
er than the expected off-times within a single pattern so the RING even reports
are issued only during the off-times between the complex patterns.

Range: = 0–255 (reporting type in the form DROF=units of 0.1 seconds>)

Regardless of its setting, the +VDR command can be disabled by the +VEM com-
mand.

+VEM=m

see “m”

Event Reporting and Masking: This command selects which detection events
are supported in voice mode. Each event is represented by a single bit of a four-
digit hex number (see the following table). Setting an event number bit to 0 means
that event is not reported. Setting a bit to 1 indicates that a detected event is re-
ported. While the event settings affect all modes (that is, playback, record, and
command modes), not just voice command mode, the mask can be changed
each time the mode is changed. Not all events are supported in each mode. See
the following table for supported events. This modem supports more features
than an IS-101 Class C-compliant modem. (Class C is the highest IS-101 com-
pliant modem, and Class A is the lowest.) See the following examples for more
information.
