3.13 DISTRIBUTED 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.
