V.34 Bit Rate Restriction
This index selects the max allowable V.34 bit rate of the physical connection when the Modulation Strap of
V34bis_V34 is selected. For instance, setting :m256=3:m270=10 will result in a 26400 speed connection or
lower.
V34BitRateRestriction UNSPECIFIED = 0,
V34BitRateRestriction 4800 = 1,
V34BitRateRestriction 7200 = 2,
V34BitRateRestriction 9600 = 3,
V34BitRateRestriction 12000 = 4,
V34BitRateRestriction 14400 = 5,
V34BitRateRestriction 16800 = 6,
V34BitRateRestriction 19200 = 7,
V34BitRateRestriction 21600 = 8,
V34BitRateRestriction 24000 = 9,
V34BitRateRestriction 26400 = 10,
V34BitRateRestriction 28800 = 11,
V34BitRateRestriction 31200 = 12,
V34BitRateRestriction 33600 = 13,
V.92 Quick Connect
This index is a feature that allows V92 clients to use previously obtained line quality configuration data to speed
up portions of the negotiation process. Disabling this feature dictates the modems should use configuration
data determined by a line probe during the negotiation process (for each call).
The supported values are:
V92 Quick Connect DISABLED = 0
V92 QuickConnect SHORT PHASE1 ONLY =1
V92 QuickConnect SHORT PHASE2 ONLY =2
V92 QuickConnect ENABLED =3
Enabling this feature (:m285=3) allows the V92 client to dictate configuration information used for both
the V8 portion (phase 1) and the modulation portion (phase 2).
Note: Line conditions can change. With this feature enabled and if line conditions change, it could actually
increase the connect time slightly.
V.8 Transmit Level
This index is used to set the transmit power for V.8. The default value of this index is a decimal value of 8992.
The provided table shows index values for 1dBm increments from –9dBm to –20dBm.
