391x Series S-Registers

S-Register		Description	DCP LCD
			Command
			Sequence
S92	V.29 Train On Data. When enabled, the modem receiver can train		Configure\Edit\
	based upon the incoming data or a training sequence from the distant		Leased
	modem. This function is necessary for a remote (tributary) modem in a
	V.29 multipoint network and is recommended for a control modem as
	well.
	Register has the following values:
	0	= Disable
	1	= Enable
	The factory setting is Disable.
S93	V.29 Retrain. When enabled, the modem transmits a training		Configure\Edit\
	sequence whenever it receives one. This configuration option should		Leased
	normally be disabled for control modems.
	Register has the following values:
	0	= Enable
	1	= Disable
	The factory setting is Enable.
S94	V29	Link Configuration. Selects point-to-point or multipoint operation.	Configure\Edit\
	Register has the following values:		Leased
	0	= PointToPoint
	1	= Multipoint
	The factory setting is PointToPoint.
S95	Trellis Multipoint (TMp) Train Time. Defines the length of time energy		Configure\Edit\
	is sent from the tributary modem to the control modem. More severe		Leased
	line conditions require longer time selections.
	Register has the following values:
	0	= 10 milliseconds
	1	= 20 milliseconds
	2	= 50 milliseconds
	3	= 100 milliseconds
	4	= 200 milliseconds
	5	= 300 milliseconds
	The factory setting is 0 (10 milliseconds).
S96	Trellis Multipoint (TMp) Tx Preemphasis. Provides amplification for		Configure\Edit\
	frequencies above the carrier frequency to compensate for high		Leased
	frequency line attenuation.
	Register has the following values:
	0	= Enable
	1	= Disable
	The factory setting is Enable.
