DESCRIPTION
Select which standard the WiMAX Device uses to handle faxes. The peer
devices must also use standard.
NONE - Disable the fax function.
G.711A Pass Through - Select this option to send and receive fax messages
over the network or Internet using VoIP (G.711a). By encoding fax data as
audio data, faxes may be susceptible to packet loss and other errors.
However, as this standard is considerably older than T.38, it is more
compatible with older orobsolete systems. Select this if you want the WiMAX
Device to work with European PCM (Pulse Code Modulation) systems.
G.711U Pass Through - Select this option to send and receive fax messages
over the network or Internet using VoIP (G.711u). By encoding fax data as
audio data, faxes may be susceptible to packet loss and other errors.
However, as this standard is considerably older than T.38, it is more
compatible with older orobsolete systems. Select this if you want the WiMAX
Device to work with American PCM systems.
T.38 FAX Relay - Select this if the WiMAX Device should send fax messages
as UDP or TCP/IP packets through IP networks. This provides better quality,
but it may have interoperability problems.
