1 Introduction

This document describes how Ericsson SS7 TCAP ANSI complies with the following ANSI Standards:

American National Standard for Telecommunications - Signaling System No. 7 (SS7) - Transaction Capabilities Application Part (TCAP), ANSI T1.114 - 2000 ([ANSI-1])
American National Standard for Telecommunications - Signaling System No. 7 (SS7) - Transaction Capabilities Application Part (TCAP), ANSI T1.114 - 1992 ([ANSI-2])
American National Standard for Telecommunications - Signaling System No. 7 (SS7) - Monitoring and Measurement for Networks, ANSI T1.115 - 1990 ([ANSI-3])

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 Signaling Solution module complies with the specified paragraph in the standard.

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

P		Ericsson Signaling Solution 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		Only point 2 is considered, use of TCAP between Exchanges and Network Service Centres.

Note 2		Layered approach is used.

Note 3		ASP is not used in the Ericsson AB implementation of ANSI-SS7.

Note 4		Connectionless mode is used (Application Service Part (ASP) is not used).

Note 5		N-COORD and N-TRAFFIC are not supported. N-NOTICE and N-STATE are partially supported (providing T-NOTICE-Ind and T-STATE-Ind respectively from TCAP to the user).

Note 8		Parameter IDs are handled transparently by TCAP.

Note 9		There is no support for connection-oriented services in the current ANSI specification. This is for further study in the ANSI standard.

Note 10		ANSI specification does not define support for this feature. This is for further study in the ANSI standard.

Note 11		Requires further study in the ANSI standard.

Note 12		TCAP ANSI does not support timestamps for events that are reported on occurrence.

Note 13		Unavailability measurements are architecturally dependent and therefore optional in the ANSI standard. Local SSN availability is reported.

Note 14		TCAP ANSI provides the necessary alarms/statistics to generate these measures but does not generate them directly.

Note 15		Measurements concerning Invoke Problems, Return Result Problem and Return Error Problem in item 17.2 are for further study in the ANSI standard.

Note 16		This module provides the necessary alarms and statistics necessary for network monitoring but does not in itself provide network monitoring.

Note 17		This module provides the basic alarms and statistics required for maintenance but does not in itself provide network maintenance.

Note 18		This module provides the basic alarms and statistics required for administrative purposes but does not actively participate in system administration.

Note 19		The Length of Contents element has a maximum length of three octets.

Note 20		In case of UNKNOWN messages TCAP does not check any Transaction IDs. Such Unknown messages are simply discarded.
