COMMENTS
Raise the level by selecting a higher setting
if too many transmission errors are occurring
on the network.
If TCP/UDP is enabled on the network, raise
this setting on the T.30 machine. Increasing
the delay time allows the recovery of more
lost packets.
If only UDP is enabled, increase the number
of redundant packets.
Level 1~2: 3 Redundant packets
Level 3: 4 Redundant packets
Selects the preamble wait time.
[00 to 0f]
There are 16 values in this 4-bit binary
switch combination.
Waiting time: set value level x 100 ms
Max: 0f (1500 ms) Min: 00 (No wait time)
The default is "0000" (00H).
COMMENTS
When "0" is selected, the bit signal reverse
method is decided by the maker code.
When "1" is selected, the bit signal reverse
method is decided by the internal bit switch.
When communicating between IP Fax
devices, LSB first is selected.)
Selects the transmit speed for IP Fax
communication.
