A Concert Server "Node" comprises all the system nodes within your Concert system. Nodes represent a logical grouping of the following system resources:

• IV-Router server application(s)
• Interface Gateway server application(s)
• Eclipse frame(s)

If all your system resources are located locally, you may choose to organize those resources under a single node. If your system resources are located at remote locations, then you may choose to organize those resources under two or more nodes. The arrangement of nodes does not affect system operation.
An IV-R is a media router. The IV-R maintains:

• A dynamic connection with the Concert Clients.
• Conference routing tables for the Clients.
• Routes audio between conference participants and messaging between clients.

Important Note: An IV-R must be present within a node to authorize an IV-R connection to the EMS, otherwise all Client connection requests will be refused.
An Interface Gateway is a processing interface to the 4-Wire audio card installed on 4-Wire enabled Concert Servers, facilitating connectivity of 4-Wire audio between Concert and external 4-Wire sources or destination (such as an Eclipse frame, for example). The configuration of each Interface Gateway instance is performed through the Concert Management Interface (CMI).
Note: You can run as many Interface Gateway instances on remote servers as you require, providing that each server is entered as an Interface Gateway node element within the CMI.
Eclipse Frame displays the Eclipse Frame page in the right-hand pane. The table displays the hostname and a brief description of each Eclipse Frame.  Eclipse is the Clear-Com digital matrix intercom system.
Note: You must use ECS (Eclipse Configuration System), the Eclipse management tool, to add Concert users to ports on an IVC-32 card installed within the Eclipse Frame. When a Concert user is configured for Eclipse through ECS, the Eclipse Frame is automatically added to the Concert database (within the first Node of the navigation tree).
Enter the Eclipse Matrix IVC-32 card IP address into the Concert setting i.e: 192.168.42.160:6001
