supporting V.34 mode.
l
Selectors 3 through 8:
Masking of symbol rate(s)
These selectors allow you to limit the transmission speed range in V.34 mode by masking the desired
symbol rate(s). Transmission speeds assigned to the symbol rates are listed on the next page. The
setting made by these selectors will limit the setting made by selectors 1 through 4 of WSW39.
If selector 3 is set to "1" to mask the 3429 symbols/second when the first transmission speed choice
is 33600 bps (specified by selectors 1 through 4 of WSW39), for example, then the allowable
maximum transmission speed will be limited to 31200 bps. If selector 8 is set to "1" to mask the
2400 symbols/second when the first transmission speed choice is 33600 bps, then the allowable
maximum transmission speed remains 33600 bps.
If selector 8 is set to "1" to mask the 2400 symbols/second when the first transmission speed choice
is 21600 bps (specified by selectors 1 through 4 of WSW39), then the allowable maximum
transmission speed remains 21600 bps but the minimum transmission speed will be limited to 4800
bps.
