GCNET and Galactic Voice 6-1
INTRODUCTION The GCNET network (Global Control Network) allows the connection of multiple,
independent XLS networked systems (each called a “Building”) on a fiber optic
backbone ring. The GCNET provides the following functionalities:
• Connection to NCC Management Stations with full site-wide event display
and control.
• FCCs (Fire Command Center) with Galactic Voice Stations for site-wide
paging and Voice system status annunciations and control.
• Inter-Building logic between XLS nodes.
In a GCNET system, each Building may have any of the following:
1) A Standalone Voice system
2) A Global Voice system
3) No Voice system
The Voice system topologies do not need to match across Buildings.
Zeus 11.05 or greater is required for GCNET functionality.
