Codes for errors that can occur during transmission because of echo:
##005, ##100, ##101, ##102, ##104, ##201, ##280, ##281, ##283, ##284, ##750, ##760, ##765, ##774, ##779,

TEL registration:
Set "Long distance (1)" when registering the one-touch speed dialing and coded speed dialing transmission mode. If
errors do not disappear, try "Long distance (2)" and "Long distance (3)".
The transmission mode set in one-touch speed dialing and coded speed dialing registration takes priority over the one
set with the service soft switch.
These bit switches are applicable to manually dialed numbers only. Look at the following table and set "Long
distance (1)" If errors persist, try "Long distance (2)" or "Long distance (3)".

Long distance (1) ignores the first DIS signal sent by the other fax.
Long distance (2) sends an 1850-Hz tonal signal when the DIS signal is transmitted.
Long distance (3) sends a 1650-Hz tonal signal when the DIS signal is transmitted.
