1 Introduction

This document describes how Ericsson Signaling TCAP ITU / ETSI / TTC / Chinese version complies with the TTC standards of 1997 specified in the following documents:

JT-Q771 1997, Function Description of Transaction Capabilities
JT-Q772 1997, Transaction Capabilities Information Element Definitions
JT-Q773 1997, Transaction Capabilities Formats and Encoding
JT-Q774 1997, Transaction Capabilities Procedures

Note however that the TTC standard specifications conform to the draft texts ITU-T Recommendation Q.771(to Q.774), studied at ITU-T SG11 meeting in February 1996. Regardless of this they are here treated as conferment against ITU-T (06/97).

For reasons of clarity, compliance with the ITU-T (06/97) recommendations detailed in the following documents are also described, as the TTC standard in practice is based on these:

Monitoring and Measurements for Signaling System No.7 Networks, ITU-T Q.752 (06/97)
Signaling System No.7 – Function Description of Transaction Capabilities, ITU-T Q.771 (06/97)
Signaling System No.7 – Transaction Capabilities Information Element Definitions, ITU-T Q.772 (06/97)
Signaling System No.7 – Transaction Capabilities Formats and Encoding, ITU-T Q.773 (06/97)
Signaling System No.7 – Transaction Capabilities Procedure, ITU-T Q.774 (06/97)
Signaling System No.7 – Guidelines for Using Transaction Capabilities, ITU-T Q.775 (06/97)

1.1 Concept

This section will explain the different concepts that will be used in the compliance lists. The terms that are used are:

C		Ericsson module complies with the specified paragraph in the standard.

N		Ericsson module does not comply with the specified paragraph in the standard.

P		Ericsson module complies partly with the specified paragraph in the standard. Specify in a note what in the module that does comply and what that does not.

-		There is nothing to implement in the referred paragraph (used in column “C”).

3 Notes

Note 1		TCAP ITU / ETSI / TTC / Chinese supports the definition of most of the specified groups, but does not group the raw measurements together.

Note 2		Faults are reported on each occurrence.

Note 3		Accounting measurements are for further study in the ITU-T standard

Note 4		Segmentation is not supported in TCAP ITU / ETSI / TTC / Chinese; all segmentation or reassemble must be performed by the TC-user.
