Hierarchical Connection of Multiple PJP Units

(Cascade Connection)

What is 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.

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.

Example: Connecting headquarter and branch A with a 2- location call and additionally connecting two divisions in two different locations to each of headquarter and branch A.

Notes

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”.
