Logical Installation
FAX redundant
Specifies the number of times each packet information is resent to the connecting device when
performing T.38 FAX communication using UDP. Different from TCP, there is no procedure
for response check, etc., for UDP. Thus, the number of times to send information can be
increased to assure that packet information is sent correctly. However, there will be a decline
in the transmission efficiency when increasing the number of times the information is sent.
Bit order
Data for specifying the send sequence of bit arrays when sending T.38 packet data.
When sending as advised, specify the normal direction.
When reversing the send sequence of bit arrays, specify the reverse direction.
Selection will be made according to the conditions of the other party's device.
The default setting is the reverse direction.
IFP packet max size
Maximum size of IFP (Internet Fax Packet) that can be sent at one time.
Since data can be sent in smaller units by decreasing the size, connection problems can be
resolved on networks with long delays.
However, decreasing the size will increase the packet overhead and result in increased of the
network load.
The default value is 290 bytes.
