Signal Quality Selection (S108)
This register selects the level of the EQM at which actions specified in the &B command
will be taken, as conditions worsen.
Range:
0-3
0
No limit
. When using this setting, loss of data may occur
and loss of carrier will not cause a V.32 or V.32bis call to
be dropped.
1
Low quality
. Very poor line conditions will cause the &B
action to be taken
(Default)
.
2
Medium quality
. Significantly degraded line conditions
will cause the &B action to be taken.
3
High quality
. Degraded line conditions will cause the &B
action to be taken.
V.32 bis Carrier Speed Selector (S109)
This register allows carrier speeds to be independently enabled and disabled.
If the bit corresponding to a certain line speed is set in this register, then that speed is
allowed to be used in connections with other high-speed modems. The actual speed
negotiated is the highest speed that both modems can support under current line conditions.
This register does not affect connections at DCE speeds below 4800 bps.

1
V.32bis enabled, automatic rate renegotiation
disabled.
