In addition, certain rules must be followed if connecting a Con-
ductor NT console to a Cnet. These rules are described in Con-

Connecting to a Control Network (Cnet)
Symphony product installations which include Conductor UX
consoles actually have two networks:
• The Onet (operations network), a single, non-redundant
network typically connected to display center terminals
and a Conductor UX computer.
• The Cnet, a single or dual Ethernet communication net-
work used by Symphony products for internodal communi-
cation. This network is primarily used for global database
transactions between Symphony nodes. The redundant
version is sometimes referred to as the redundant network,
redundant data highway, dual network or process network.
In a typical Symphony product installation which includes
Conductor UX consoles, Symphony controller devices are con-
nected to the Cnet, display center terminals (DCTs) are con-
nected to the Onet, and operator station computers (the
Conductor UX computer) are connected to both.
All Conductor NT server consoles must be connected to the
Cnet, enabling the servers to access global databases. Conduc-
tor NT client consoles can also be connected to the Cnet. The
preferred method of connecting to the Cnet is with a Symphony
dual Ethernet controller (ECCP). As the terms dual network
and redundant network imply, the redundant Cnet has two
redundant physical highways, known as Highway 1 and High-
way 2. (For an example, refer to Appendix D.)
However, if the Conductor NT console is not equipped with an
ECCP board but does contain a third-party Ethernet board, it
can be connected to either Highway 1 or Highway 2 of a redun-
dant Cnet, or to a single Ethernet Cnet. (For an example, refer
to Appendix D.) When devices are connected to only one high-
way of a redundant Cnet, all nodes using only a single connec-
tion to the Cnet must be connected to the same
samesame
same highway. This
means of connection can be used for both server and client
consoles.
