Bonding *
Bonding is one of the Inverse Multiplexing
methods allowing the connection of the
videoconferencing system with multiple
ISDN lines. Dialing the first ISDN line
enables you to connect all other lines.
Dialing the second and later lines is done
automatically by the communication
between the videoconferencing systems on
both sites. To use bonding, it is required that
both videoconferencing systems be
equipped with the bonding function and that
“Area Code” and “Local Number” in the
ISDN Setup menu of the answering site be
set correctly. As the communication
between the systems when using the
bonding function is made via the ISDN
numbers of the answering site, the “Area
Code” and “Local Number” settings in the
ISDN Setup menu are not essential at the
dialing site.
