t38TCFmethod

This object determines the method used to verify
the TCF(Training Check Field). 
              
For UDP-based fax transport, its value should be set 
to networkTCF. For TCP-based fax transport, its value 
should be set to localTCF. A value of localTCF may be 
used in rare circumstances for UDP-based fax transport. 
              
A value of networkTCF implies that date rate management 
is done end-to-end between the group 3 fax terminals, 
in a manner similar to the PSTN(Public Switched 
Telephone Network). In this case, the TCF training
signal is passed transparently by the IP network. 
              
A value of localTCF implies that media gateways are actively 
involved in the training and data rate management procedure, 
including the generation of the TCF training signal.
Data rate management is done by one of the media gateways on 
the basis of local results and results forwarded over the IP 
network by the other gateway. The other gateway generates
the TCF training signal towards its group 3 fax terminal.
