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.
