4.14 Conformance
This section describes the Protocol Implementation Conformance Statements
(PICS). Every vendor of a device shall fill out these tables completely.
There are 4 parts of the PICS:
- Part 1 states information about the implementation and system
- Part 2 is a list of the supported services
- Part 3 is a list of the supported parameters
- Part 4 is a list of the local implementation values
