1.1 Introduction

This document contains a compliance statement for the UK ISUP module versus ND1007:2007/01. The compliace will be made versus ITU-T rec. with additions from ND1007:2007/01 ince ND1007:2007/01 [7] contains differences form ITU-T recommendations.

The functionality or compliance of the Call Control application [5] is not addressed in this document ( Note 26).

1.2 Concept

The terms that will be used are:

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

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

P		EIN 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 and Comments

Note 1:		Using Signalling Connection Control Part (SCCP) as a service provider is not supported.

Note 2:		Automatic repeat attempt on continuity check failure is not supported.

Note 3:		The Pass-along end-to-end signalling method is supported, but not the SCCP method.

Note 4:		Procedures necessary to fully support this function/service is the responsibility of the Call Control application. Messages and parameters involved are transparently handled by this ISUP.

Note 5:		Compatibility information regarding parameters is handled by Call Control.

Note 6:		The USR message is allowed during all states of a call, even though the Facility request message will always be answered with Facility reject.

Note 7:		CMC, CMRJ and CMR are not supported, and will cause a Confusion message(CFN) to be sent.

Note 8:		A received CQR is correctly answered with a CQM. This ISUP never sends CQR.

Note 10:		FOT can be sent by this ISUP, but discarded if received.

Note 11:		FAC, IDR, IRS and NRM are either passed transparently to Call Control, or handled according to supplied compatibility information.

Note 12:		Can be sent or received by this ISUP if configured as National message. Can be answered with FRJ without the delivering to the Call Control if configured.

Note 13:		INR can be used only to request the Calling party number. Other indicators are always ignored. The Call control application is not engaged.

Note 14:		OLM message used in Temporary Trunk Blocking is never sent by this ISUP.

Note 15:		All parameters and indicators are handled by this ISUP module or passed transparently to/from the Call Control application, except those contained in unsupported messages.

Note 16:		National messages are, if defined in the ISUP module configuration file, passed transparently to/from the Call control application. National parameters are always passed transparently.

Note 17:		Multirate connection types are not supported.

Note 18:		Only action at the national originating and destination exchange is supported.

Note 19:		Depends on the functionality of the Call control application above ISUP.

Note 20:		This ISUP can be configured to send an INR when ‘Calling party number‘ is missing in the received IAM. The call will be held until an INF is received or timer T33 expires.

Note 21:		Additional methods are available.

Note 22:		Gateway exchange and Transit exchange roles are not supported.

Note 23:		Load control may be applied by the Call control application and/or the Management function, in which case the ACC parameter will be included in outgoing Release messages. An incoming ACC parameter is handled by this ISUP.

Note 24:		The time-out values are defined in the configuration file

Note 25:		An unsolicited INF will be passed transparently to the Call control application.

Note 26:		Recommendations Q.731-Q.737 are not addressed in this document, since they describe functionality only applicable to a Call control application.

Note 27:		ISUP support most of the definition rules of the groups, but has not grouped them together.

Note 28:		Every fault or measurement is reported on occurrence instead of the first occurrence and then the number of occurrences in some interval.

Note 29:		Timestamps on events reported on occurrence are not supported by the ISUP module.

Note 30:		Unavailability measurements are architecturally dependent and are optional in the ITU standard. An indication of the module availability is reported.

Note 31:		Remote measurements are only necessary at gateway signalling points.

Note 32:		Measurements are not provided periodically but can be retrieved on-demand by an external management application.

Note 33:		Timeout of individual and group circuit reset (T17 and T23) is a combined measurement - no individual measure is available.

Note 34:		No distinction is made between individual and group circuit blocking therefore a combined measurement is used. i.e. T19 and T21 are used instead of T13 and T15.

Note 35:		A number of individual alarms are raised on unexpected and incorrectly formatted errors. These can be combined by an external management agent to obtain a single alarm where required.

Note 36:		If CPG message is received before reception of ACM message (unexpected CPG) during outgoing call setup phase it is configurable to release the call in this sitaution or not.

Note 37:		Can be sent or received by ISUP if configured as National message only. Otherwise will be discarded.

Note 38:		Enhanced echo control signaling procedures are not supported.

Note 39:		If the circuit is seized by a call, and unexpected message is received before receipt of a backward message required for the call set-up, Reset Circuit Message is not sent.

Note 40:		ISUP on receipt of unrecognized messages and/or parameters doesn' t include diagnostic field, dependent on the cause value, containing the message type code and/or parameter name(s).

Note 41:		If CPG message is received before reception of ACM message (unexpected CPG) during outgoing call setup phase then the call will not be released. CPG also can' t be sent before answer for outgonig call and discarded if received before answer for incoming calls.
