| Description | This object contains the default time out value for the
off-hook warning 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 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. |
