Groups are organized according to the TSS. Additional referencesare added to identify the actual test suite and whether it applies to the network or the user (see table 1).Table 1: TP identifier naming convention schemeIdentifier:__=protocol specification: "GFP"=type of IUT:UUserNNetwork=group2 digit field representing group reference according to TSS=sequential number(001-999)5.1.2Source of TP definitionThe TPs are based on EN 301 061-1 [2].5.1.3TP structureEach TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPsmore readable and checkable. A particular structure has been used and this is illustrated in table 2. This table should beread in conjunction with any TP, i.e. use a TP as an example to fully understand the table.SIST EN 301 061-3:2001

PICS: MCu 1.The following TPs are testing the procedures associated with the transport of components using the messages for theestablishment and clearing of calls.The primitive exchanged between the different entities are not observable. Only the PDU exchanged between peerimplementations can be observed.So to check that the component is properly transmitted to the Generic Functional Transport (GFT) entity, it shallprovoke a reaction from Remote Operations Service Element (ROSE) entity that will request the transmission of thecorresponding component response. This component will be transmitted in a call related message with the same callreference, which is observable.SIST EN 301 061-3:2001

Groups are organized according to the TSS. Additional referencesare added to identify the actual test suite and whether it applies to the network or the user (see table 1).Table 1: TP identifier naming convention schemeIdentifier:__=protocol specification: "GFP"=type of IUT:UUserNNetwork=group2 digit field representing group reference according to TSS=sequential number(001-999)5.1.2Source of TP definitionThe TPs are based on EN 301 061-1 [2].5.1.3TP structureEach TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPsmore readable and checkable. A particular structure has been used and this is illustrated in table 2. This table should beread in conjunction with any TP, i.e. use a TP as an example to fully understand the table.SIST EN 301 061-3:2001

PICS: MCu 1.The following TPs are testing the procedures associated with the transport of components using the messages for theestablishment and clearing of calls.The primitive exchanged between the different entities are not observable. Only the PDU exchanged between peerimplementations can be observed.So to check that the component is properly transmitted to the Generic Functional Transport (GFT) entity, it shallprovoke a reaction from Remote Operations Service Element (ROSE) entity that will request the transmission of thecorresponding component response. This component will be transmitted in a call related message with the same callreference, which is observable.SIST EN 301 061-3:2001
