#### 7.2.3.4 IfcCommunicationsApplianceType

| Type d'appareil de communications
| Kommunikationsgerät - Typ

The flow terminal type IfcCommunicationsApplianceType defines commonly shared information for occurrences of communications appliances. The set of shared information may include:

- common properties with shared property sets
- common representations
- common materials
- common composition of elements
- common ports

It is used to define a communications appliance type specification indicating the specific product information that is common to all occurrences of that product type. The IfcCommunicationsApplianceType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcCommunicationsApplianceType are represented by instances of IfcCommunicationsAppliance. Refer to the documentation at IfcCommunicationsAppliance for supported property sets, materials, composition, and ports.
