Send and Receive Modem
If you need to place and receive calls with the modem, use the setup shown in
Figure 4-10. This setup makes line A the primary modem line, but keeps the line
available for users at other extensions when all other lines are busy.

To Use
Calls on the modem line (line A) ring only at extension X. Also, line A is the last
line selected by other extensions, so the modem line is unavailable for the
modem only when all other lines in the system are being used.
To Program
1.
Use Line Assignment (#301) to assign one or more lines to extension X
(including line A).
2.
For extension X, set Automatic Line Selection to select outside lines first (line
A selected last).
For all other extensions, set Automatic Line Selection so that line A is the
last line in the select sequence. That way, the modem line is used for
outgoing voice calls only when all other lines are busy.
3.
Set Line Ringing for line A at extension X to Immediate Ring. Set all other
lines assigned to extension X to No Ring. (For all other extensions, set line
A to No Ring.)
4.
Set Automatic Extension Privacy (#304) for extension X to Assigned.
5.
Make sure extension X is not assigned as a Call Waiting (#316) extension,
Pickup Group Extension (#501), Calling Group Extension (#502), Night
Service Group Extension (#504), or Hunt Group Extension (#505).
