-= Pete Replied to Arthur Marsh about: high-end modems failing dial tone detection =-

G'day Arthur

Guess so though with all the differing exchanges about who knows, I
can only comment on my own experences with about 5 different modems
over the years rangeing from Bit Blitzer 2400 up to USR Courier with a
few Netcomms and Dataplex in between and they all detected dial tone
just fine on both the old mechanical (i assume X-bar) exchange and the
new AXE one we have now.
