This object specifies the TPKT header version that is
dynamically assigned based on the size of the packet
presented to TCP layer.
The TPKT header version is set to 3 when the size of packet
is represented by 2 octets of packet length field for
the message (TPDU) sizes less than or equal to 65531 octets.
If this object is set to 'true':
- The TPKT header version is set to 4 when the size of packet
is represented by 4 octets of packet length field for
the message (TPDU) sizes greater than 65531 octets.
If this object is set to 'false':
- An error in message is sent to MGC if the TPDU
size exceeds 65531 octets indicating that response size
exceeded maximum PDU size.
