scope:

This second part of ETS 300 438 provides the Protocol Implementation Conformance Statement (PICS) proforma for the Service Specific Co-ordination Function (SSCF) at the Signalling ATM Adaptation Layer (SAAL) for support of signalling at the Network Node Interface (NNI) for the Broadband Integrated Services Digital Network (B-ISDN) as specified in ETS 300 438-1 [2] in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [4].

This PICS proforma applies to the B-ISDN SSCF for NNI signalling and the Service Specific Connection- Oriented Protocol (SSCOP, see ETS 300 436-1 [1]) implementation used to support it. Certain mandatory SSCOP functions are not necessary for the support of NNI signalling, but may be needed to support other SSCFs. This PICS proforma identifies such mandatory functions as optional for NNI signalling.

The supplier of a protocol implementation that is claimed to conform to ETS 300 438-1 [2] is required to complete a copy of the PICS proforma provided in annex A of this ETS and is required to provide the information necessary to identify both the supplier and the implementation.
