S48

Program V.34bis Connect Speeds (2834 Series only)

Unit:	N/A
Range:	33, 31, 28, 26, 24, 21,19,16,14,12, 96 and 48
Default:	0
Description:	Defines which speed modem connects within the scope of Enhanced V.34 mode
	(e.g., S48 = 26 means maximum connect speed is 26.4K). This register
	compensates for line conditions that have trouble supporting higher Enhanced V.34
	speeds (e.g., 33.6K, 31.2K, 28.8K, 26.4K, 24K...). The modem default is a value of 0,
	which indicates a connection attempt of 33.6K.
