There were 2 models of the 1670 though I do not know why. Th book you have is
for one type and the modem is the other the switch functions are not quite
the same as I recall- and I have the docs to prove it.
3 switch model sw1 up -- regular home/single line
dn -- PBX multi-line
sw2 up -- Amanlog loopback seft-test
dn -- normal operation
sw3 up -- no carrier detect signal
dn -- for carrier detect signal on pin h-k of the edge connector
4switch model sw1 dn -- Auto answer suppressed
up -- answer on 2nd ring
sw2 dn -- carrier detect on H-K edge of connector
up -- no carrier detct
sw3 dn -- enable the speed indicate signal to the computer
up -- disable speed indicate
sw4 dn -- DTR always on
up -- DTR normal computer controls DTR signal
