| Description | This object contains the default time out value for busy
tone. 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 Management
Station, 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. |
