Call Setup Using the RS-366A Dialing Procedure

The Concorde¥4500 operates with both dialed and nondialed network
devices. Dialed network calls are placed by pressing numbers on a
keypad or keyboard, which are then passed to the telephone
company, who in turn places the call depending on the type of
hardware and network conÞguration you have.
For a videoconferencing system to pass dialing information to the
external network interface device, RS-449 and V.35 devices must
have an RS-366A dialer port(s).
Nondialed network calls can be made immediately from place to
place or device to device because there is a dedicated line between
two pieces of equipment. When a call is made, there is no dialing
involved because the line is always open. The Concorde¥4500 uses
one of the following nondialed network interfaces:
RS-449
V.35
X.21
For the Concorde¥4500 videoconferencing system to make a call
using the RS-366 A dialing procedure, signals in the Concorde¥4500
dialer port and channel data port on the RS-449 or V.35 interface
board must set up the call.
