HIERARCHICAL CONNECTION OF MULTIPLE PJP UNITS (CASCADE CONNECTION)

The cascade connection classifies the PJP units to be
involved in a call into the servers and clients, connects
each client to a server and establishes the call by
interconnecting the servers. While the maximum number
of locations that can be connected in normal connection
mode (mesh mode) is 4, a larger number of locations can
be connected by means of the cascade connection.

• To use the cascade connection, all of the PJP units involved in

the call should be set to one of the cascade connection modes. A
unit set to the normal connection mode (mesh mode) cannot be
connected with a unit set to a cascade connection mode.

• During a cascade connection, the audio is always reproduced in

the monaural mode even when “Speaker Mode” (page 29) is set
to “Divide”.

■ The maximum number of locations by

the cascade connection

Up to 8 locations can be connected by means of the
cascade connection. To establish the connection of 8
locations, you need to connect the servers and clients as
shown in the following figure.
