Not at all.
The receiving fax initiates in both cases. What I meant was a data
modem will cycle though 3 or 4 cadences attempting to link up,
while a fax {AFAIK} only does one or two.
The CNG tone from the sender fax has nothin to do with the
receiving modem. Its function is to disable telco echo canceling
en route.
