scope:

The CEBus specification covers:

• The overall topology of the CEBus network and the detailed topology for each individual medium used.

• The electrical and physical specifications for the media usable by CEBus

• The protocol to be used for network access and the description of the control message format.

• A command language that allows all devices to communicate a common set of functions to be performed.

Aspects of the overall CEBus network that are not addressed in this specification are operation and maintenance of the network.

This standard establishes a minimal set of rules for compliance, It does not d e out extended services that may be provided, as long as the rules of this standard are adhered to within the system. It is in fact, the intention of the standard to permit extended services (defined by users) to coexist.

Certain aspects of the standard, such as regulatory requirements or other standards, are defined in other documents. These documents will be referenced when relevant (either in the particular section document or in Section 7). In the case where a referenced standard conflicts with IS-60, IS-60 specifications will prevail.
