Figure 2-1. Digital Chassis
The following is specified per the Digivance CXD system configuration:
• Sonet Interface Module
• Systems Interface Module
• Reverse Simulcast Module
• Master Processor Module
• Slave Processor Module
The quantity for each module is determined by the tenant network configuration. Note that
each card slot is not equivalent, thus requiring certain modules to be specifically located within
the chassis. Labeling is provided on the chassis for correct installation of the modules.
Selection of the modules for this chassis and the Digital Chassis itself should be done in
accordance with Table 2-1.
Table 2-1. Digital Chassis Module Selection Rules
