Tx level If communication with a particular remote terminal
often contains errors, the signal level may be
inappropriate. Adjust the Tx level for communications
with that terminal until the results are better.
If the setting is "Disabled", the NCU parameter 01
setting is used.
• Do not use settings other than listed on the
left.

Cable equalizer
Bit 7: 0, Bit 6: 0, Bit 5: 0 = None
Bit 7: 0, Bit 6: 0, Bit 5: 1 = Low
Bit 7: 0, Bit 6: 1, Bit 5: 0 = Medium
Bit 7: 0, Bit 6: 1, Bit 5: 1 = High
Bit 7: 1, Bit 6: 1, Bit 5: 1 = Disabled
Use a higher setting if there is signal loss at higher
frequencies because of the length of wire between
the modem and the telephone exchange when calling
the number stored in this Quick/Speed Dial.
Also, try using the cable equalizer if one or more of
the following symptoms occurs.
Communication error with error codes such as 0-20,
0-23, etc.
Modem rate fallback occurs frequently.
• Do not use settings other than listed on the
left.
If the setting is "Disabled", the bit switch setting is
used.

Initial Tx modem rate If training with a particular remote terminal always takes too
long, the initial modem rate may be too high. Reduce the
initial Tx modem rate using these bits.
For the settings 14.4 or kbps slower, Switch 04 bit 4 must
be changed to 0.
• Do not use settings other than listed on the left. If
the setting is "Disabled", the bit switch setting is
used.
