3.13DISTRIBUTED MULTISITE / STARGATE CONFIGURATION

A common or central network switch known as a "StarGate Controller" has three or more switches linked to it via NIMs. Users select network operation on a wide area fleet/group basis at the System Manager. Each NIM is assigned a unique site assignment number (1 thru 32) within the CEC/IMC. This number corresponds to and matches the site assignment number set via the 5-bit DIP switch setting on the interface module’s Controller Board. There are three steps that must be completed to correctly configure StarGate operation:

1.Unit/Group databases set-up for Multinode operation and downloaded from System Manager

2.NIM TDM bus/slots and channels equipped

3.StarGate configuration as described in the following paragraphs.

StarGate Configuration

StarGate Configuration allows the user to configure group call console tracking, remote CEC interface operation, and NIM control data link baud rates for the network. These parameters are all set on a per NIM basis.

The CEC/IMC ID ("switch assignment number") must be set at the MOM Controller Board before distributed multisite communications will operate correctly. The CEC/IMC firmware will automatically display a CEC/IMC ID number even if one is not set at the MOM; therefore, a displayed CEC/IMC ID does not guarantee that the number has been set. Ensure that this switch assignment number has been set using the DIP switches on the MOM Controller Board as specified in the Distributed Multisite/StarGate Configuration section of LBI-38938,CEC/IMC Digital Audio Switch Installation, Set-up, and Troubleshooting.

StarGate configuration is accomplished from the StarGate / Remote CEC / NIM Configuration dialog box, Figure 34. From the CEC/IMC Manager menu bar select Configure System /

System Options / StarGate to display the StarGate / Remote CEC / NIM Configuration dialog box.
