MI/MIC Operations
Couriers are shipped with MI/MIC disabled, that is, for normal
use. Mode Indicate/Mode Indicate Common (MI/MIC) closure
is required for some applications where existing hardware, such
as a PBX, does the dialing.
For these applications, the Courier must power up in Originate
mode. Then the Courier goes on line and accepts data when it
connects with the number dialed by the system equipment.
Once you've set Register S34, have the system force the modem
off hook by closing the MI/MIC leads in the phone line
connector.

the vinyl feet.
