Fax Transmission
This chapter describes how to perform fax transmissions in clear channel and T.38 with the Mediatrix 4100.
Introduction
The Mediatrix 4100 handles G3 fax transmissions at speeds up to 14.4 kbps. Automatic fax mode detection
is standard on all lines. Real-Time Fax Over UDP with the T.38 protocol stack is also available.
The quality of T.38 fax transmissions depends upon the system configuration, type of call control system used,
type of Mediatrix units deployed, as well as the model of fax machines used. Should some of these conditions
be unsatisfactory, performance of T.38 fax transmissions may vary and be reduced below expectations.
All lines of the Mediatrix 4100 can simultaneously use the same codec (for instance, T.38), or a mix of any of
the supported codecs. Set and enable these codecs for each line.
