6)BIT STUFFING
When enabled, bit stuffing causes the T1 ESF CSU ACE to monitor

maintain ones at 12.5 percent. This option should be disabled if
B8ZS is enabled. The factory default is DISABLED.

7)SET LBO
Selects the line build out for the network interface. In AUTO mode,
the T1 ESF CSU ACE sets the LBO based on the strength of the
receive signal. The factory default is 0 dB.
0 dB
-7.5 dB
-15 dB
-22.5 dB
AUTO
When interfacing to a Smart jack, the 0 dB setting typically works best
because most Smart jacks expect a strong receive level. The AUTO setting
should only be used when no Smart jack is present and the T1 ESF CSU
ACE is interfacing to a repeater.
