T.38 Fax Transmission
T.38 is an ITU recommendation for allowing transmission of fax over IP networks in real time.
PROs
•
Allows for redundancy, therefore increases the reliability of the transmissions.
•
Faxes in T.38 are not as sensitive to network imperfection like packet loss or jitter as faxes in
Clear Channel.
CONs
•
The number of redundancy packets will increase the bandwidth used
•
The higher the speed, the more bandwidth is used.
•
May take more bandwidth than a fax in Clear channel.
Requirements
•
The Mitel unit must be able to detect a CNG, v21 preamble or T.38 packet to switch to T.38
•
Reasonable delay, 1 second round trip is acceptable however 2 seconds could cause timeout
or collision
Configuration
