22、ontrol (DLC) layer is layer 2b of the DECT protocol stack. The separation of the user information from the DECT signalling data is managed by the allocation of two independent planes: (24 Medium Access Control layer Physical layer (1) Lower Network layer Figure 1 : DECT protocol stack The U-plane is

23、 the part of the DLC implementation that is responsible for the transmission of the user data. The U-plane may provide a series of different services and facilities, grouped into categories (LUX families). The C-Plane is the second part of DECT DLC and is mainly involved with the transfer of signall

24、ing information. It provides the means to support DECT Connection Oriented, Connectionless and Broadcast services (the broadcast service exists only at the FT to PT direction). DECT DLC provides three classes of operation (Unacknowledged for C/L services, Single frame and Multiframe for C/O services

25、). At the DLC layer, C-plane and U-plane resources are considered as completely independent. The association of C and U-plane resources to serve a higher layer service (e.g. to setup and maintain a call) is a NWK layer responsibility. Moreover, no interaction is required between the services provide

26、d by each of the planes. Figure 2 shows the DLC (TSS) including its subgroups and defined for the conformance testing.

28、ls. The first level creates two protocol groups representing the protocol plane. The second level separates the protocol plane in functional modules. The last level contains the standard IS0 subgroups CA, BV, BO and BI. 4.3.1 Protocol groups The protocol groups identifies the DECT DLC planes, C-Plan

The first functional module identifies the LAPC Class U services. The second functional module identifies the LAPC Class A services. The third functional module ident

31、 The TP Id is a unique identifier it shall be specified according to the TP naming conventions defined in the subclause below. The reference should contain the references of the subject to be validated by the actual TP (specification reference, clause, paragraph). The condition defines in which init

Definition of the events that are expected from the IUT to conform to the base specification. 4.3.1.2 U-plane group The U-plane protocol group is divided in five functional modules. Th

33、e first functional module identifies the Class O transmission procedures. The second functional module identifies the Class 1 transmission procedures. The third functional module identifies the Class 2 transmission procedures. The forth functional module identifies the Class 3 transmission procedure

34、s. The last functional module identifies the LU3 LAP-U protocol. 4.3.2 Main test groups The main test groups are the Capability group (CA), the Valid Behaviour group (BV), the inopportune Behaviour group (BO) and the Invalid Behaviour group (BI). 4.3.2.1 CApability (CA) tests This test sub group sha

Valid PDU, means, that the exchange of messages and the content of the exchanged messages are considered as valid. 4.3.2.3 InOpportune Behaviour (BO) tests This test sub group shall verify that the IUT is capable of a valid reaction, when an inopportune

37、 protocol event occurs. Such an event is syntactically correct but it occurs when it is not expected. 4.3.2.4 Invalid Behaviour (BI) tests This test sub group shall verify that the IUT reacts in conformity with the DPRS standard 2, on receipt of a syntactically invalid PDU. 5 Test Purposes (TP) 5.1
