| Description | This object contains the default time out value for message
waiting indicator. The MTA MUST NOT update this object
with the value provided in the NCS message (if
present). If the value of the object is modified by the
SNMP Manager application, the MTA MUST use the new value
as a default only for a new signal requested by the NCS
message.
The time out (TO) elements are intended to limit the time
a tone or frequency is generated. When this MIB object is
set to a value of '0', the MTA MUST NOT generate the
corresponding frequency or tone, regardless of the
definitions pertaining to frequency, tone duration, or
cadence. |
