These interoperability tests apply in the international network but may also beapplied in national networks. Successful conformance or validation testing of SCCP itself, SCCP applications andMessage Transfer Part (MTP) is a pre-requisite of interoperability testing. It is recommended that interoperability testingis performed on signalling nodes that are not in service.Interoperability testing may require the use of a monitor to check the operation of the signalling node(s) under test. Thespecification of this monitor is not covered by the present document although the general requirements are that theequipment is capable of capturing all data on the signalling link, and preferably be able to decode the informationcaptured into SCCP messages.The tests in the present document are only a basic set in gaining confidence in the interoperability of SCCPimplementations. Specific interconnections may require more interoperability testing than specified here. The specificrange of tests performed between nodes is subject to bilateral or multilateral agreement and also dependent on thefunctionality of the implementations under test. The tests are shown in one direction of testing, thus they should berepeated in the reverse direction for completeness.SIST EN 301 008:2000
ETSIEN 301 008 V1.1.2 (1998-05)74.2Network and implementation dependency considerationsSCCP applications may be external to the nodes under test (e.g. external testers).Where the receiving node is a stand alone SCCP relay Sub System Number (SSN) routing to it cannot be used. In thiscase tests using SSN routing are not applicable.In some implementations SCCP and MTP
availability are inseparable (e.g. in the case where MTP and SCCP arehandled together). In such cases tests that require the availability status of SCCP and MTP to be different cannot be run.If the nodes under test are in service it is inadvisable to run tests that require the MTP or SCCP to be unavailable.4.3Test network configurationThe following network configuration is intended to show a typical international SCCP network scenario and is the basisof all the tests in the present document. In practice, in some cases, node B (i.e. a "stand alone" SCCP relay node) maynot exist. In these cases the relay functionality part of the tests may still be applied but would relate to internationalgateway nodes A and C.SCCP MessagesSCCP MessagesSCCP MTP(Int.
