1.	Introduction
Prior to the conformance testing and the interoperability testing of two IUTs, it is necessary to have the PICS (Protocol Implementation Conformance Statement) documents for both implementations. 
This particular PICS deals with the implementation of the SONET STS-3c Physical Layer Interface.
 
1.1	Scope 
This document provides the PICS proforma for the STS-3c Physical Layer Interface as described in Section 2.1 of the ATM User-Network Interface Specification Version 3.0 [1], in compliance with the relevant requirements, and in accordance with the relevant guidelines, given in ISO/IEC 9646-2 [3].

Identification of the protocol 
This PICS proforma applies to the following document:
	ATM Forum, "ATM User-Network Interface Specification Version 3.0", 1993.

3.	PICS Proforma
3.1	Global Statement of Conformance
The implementation described in this PICS meets all of the mandatory requirements of the reference protocol.
         ___Yes
        ___No
Note: Answering "No" indicates non-conformance to the specified protocol. Non-supported mandatory capabilities are to be identified in the following tables, with an explanation in the comments section of each table of why the implementation is non-conforming.

3.2	Instructions for Completing the PICS Proforma
The PICS Proforma is a fixed-format questionnaire. Answers to the questionnaire should be provided in the rightmost columns, either by simply indicating a restricted choice (such as Yes or No), or by entering a value or a set of range of values.
A supplier may also provide additional information, categorized as exceptional or supplementary information. This additional information should be provided as items labelled X.<i> for exceptional information, or S.<i> for supplemental information, respectively, for cross reference purposes, where <i> is any unambiguous identification for the item. The exception and supplementary information are not mandatory and the PICS is complete without such information. The presence of optional supplementary or exception information should not affect test execution, and will in no way affect interoperability verification.
