Note:
WSW40 takes effect only when the V.34 mode is permitted (WSW19, selector 7) in models
supporting V.34 mode.
- 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 on 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 on WSW39), then the
allowable maximum transmission speed remains 21600 bps but the minimum transmission
speed will be limited to 4800 bps.
