Paradyne 2001 User Manual page 47

Table 5-1 shows in greater detail what occurs during the
initiation of a VoiceSpan session with manual dial and manual
answer.
Table 5-1. Initiating a VoiceSpan Session (1 of 2)
Originating End
The originating user lifts the
receiver and tone dials the
phone number of the
answering end.
A standard voice call conversation begins. The two users
establish the following:
1. Whether both users have multimedia communicators
supporting VoiceSpan.
2. What application the users will run on their respective DTEs.
3. Whose DTE application will originate a call to initiate
VoiceSpan operation. (In this example, the same side
initiates VoiceSpan operation that initiated the call, but this
is not required.)
The user on the other end
starts the application. If the
application requires it, the user
starts it in Originating mode.
Because most modem-to-modem applications are not designed
for a situation where the telephones are already connected, the
DataPort 2001s at this point simulate the initiation of a
telephone call.
Answering End
The answering phone rings,
and the answering user picks
up the receiver.
The user on one end starts the
application. If the application
requires it, the user starts it in
Answer mode.
