Ethernet Network Installations
The ONYXWorks
®
Workstation is a Proprietary Supervising Station that has a supervised client
server architecture that communicates over Ethernet (TCP/IP) networks. The IP network can be a
shared bandwidth system that operates over topologies such as an intranet, the Internet, or a frame
relay system. ULC does not allow operation over an Internet connection.

clients, in the most basic system, can co-exist on one computer. For more powerful
systems, multiple computers can be networked together over the IP network running multiple
instances of the Workstation software application or other clients and gateways.
If the Workstation or gateway are sharing on-premises communications equipment, the shared
equipment shall be “listed for the purpose”. “Listed for the purpose” has been formally interpreted
by NFPA (Formal Interpretation 72-99-1) for equipment on packet switched networks as being
listed to the requirements applicable to general purpose communications network equipment.
For ULC applications, the Internet cannot be used for either primary or ancillary functionality.
