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.

Note 5		TCAP ITU / ETSI / TTC / Chinese provides the raw measurements necessary to calculate these statistics.

Note 6		No measurements in table 14.1, section 5.3(Q.752) are logged per destination address.

Note 7		No measurements in table 14.4 through 14.6, section 5.3(Q.752) are logged per destination address. The address may instead be obtained from the alarms raised by TCAP ITU / ETSI / TTC / Chinese which are logged on every occurrence.

Note 8		The supported management primitives requires that the information is directed to a specific subsystem. It is up to SCCP to send the information to each an every subsystem that is to be informed.

Note 9		The Length of Contents element has a maximum length of 3 octets.

Note 10		The Remote Cancel by the TC-user is applicable to the TC-user only.

Note 11		Applicable to the TC-user only.

Note 12		States ‘Wait for Reject’ and ‘Reject Pending’ are not implemented in TCAP ITU / ETSI / TTC / Chinese.

Note 13		Invoke IDs may be reallocated immediately on return of the corresponding Invocation State Machine to the Idle State.

Note 14		TCAP ITU / ETSI / TTC / Chinese checks for a Sequence of Externals in User Information but not the format of data within each External.

Note 15		Compare with the information in this report for section 5.3 of Q.75.

Note 16		Protocol Version is Mandatory for the outgoing AARQ in TCAP ITU / ETSI / TTC / Chinese

Note 17		Additional change of originating address according to the standard 3G TS 23.006 (Support of Mobile Number Portability) also supported
