28、e standards ES 200 778-1 i, ES 200 778-2 2 and EN 300 659-3 3 contain no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standards and the PICS specification ES 200 778-3 4. The TPs are only based on conformance requirements related to the externally

29、observable behaviour of the IUT, and are limited to conceivable situations to which a real implementation is likely to be faced. All the test purposes are mandatory unless they have selection criteria. Optional test purposes (with selection criteria) are applicable according to the configuration opt

30、ions of the IUT. A PICS item shall cover the configuration options. Unless specified: all the messages contain at least the mandatory parameters, and the parameters use correct values; neither a message nor a parameter, which can lead to a fail or an inconclusive verdict, shall be used. 5.2 Test Pur

31、poses for subscriber line protocol Selection: FSK supported: PICS: MC. 1 The following test purposes are intended to check the correct implementation of the protocol over the local loop for display and related services on Access and Terminal equipment. This protocol consists for the LE of sending me

32、ssages to the TE, which reacts by activating indicators (e.g. a led) or displaying the received information (calling line Id for example). Except the TE-ACK signal in Off-hook mode (see note), there is no signal sent to the LE indicating the correct reception of the received information. NOTE: The e

33、xception is the operation of the physical layer in the case of Off-hook mode where the TE replies with a TE-ACK signal to the alerting signal. In this particular case, the tester can ensure the correct interpretation of the TAS signal sent by receiving the TE-ACK signal from the Terminal. To ensure

34、the correct reception of the messages by the TE, the test operator shall observe the reaction of the IUT after execution of the test. The operator will than send a signal to the test system (e.g. key Y or N) that reflects the reaction of the IUT on receipt of the message. A correct reaction of the I

35、UT observed by the test operator would also assume that the TE has received the message. In the following Physical and DL test purposes, “correctly receives“ means that the test operator can observe the correct reaction of the IUT. In the Presentation test purposes, “displays“ means that the indicat

36、ed parameters were correctly interpreted by the IUT (either by display or sound, etc.). ETSI 12 ETSI ES 200 778-4 VI .I .2 (2002-1 1) and communicates the result to the test tool The operator observes the reaction of the IUT, NOTE: This test method is common to all layers. The method of displaying d

37、epends on the IUT (display on screen, on a printer, on a light, audio message, tone, etc.). Example (CCBS): A Call Set-up message is sent to the original calling IUT. In this message, the parameter Call Type is set to CCBS. It depends on the IUT how to interpret this parameter. Some selected actions

38、: a) Ringing, as it is usually done. The user will be informed about CCBS call back situation by signalling tones when taking the call (e.g. taking the handset). b) Special ringing cadence used for CCBS call back only. c) Ringing and additionally indicating on the screen about CCBS call back situati

39、on. All the presentation test purposes in the present document use the neutral expression “to display“ in order to allow an independent description. Therefore, the expected method of display has to be described prior to the execution of tests. Figure 1: Manual observation of test result 5.2.1 PHYsic

40、al (PHY) The conformance of the physical layer of the TE under test will therefore be diagnosed by either proper reception or no reception of messages by the IUT at the presentation layer, sent through the physical and the DL layers. Absence of reception of a message may result from no support of th

41、e IUT for that particular service or parameter, from the non-conformance of the physical layer of the IUT or from the test purpose itself which is to test the physical layer of the IUT in out of specification ranges. In case of receipt of a valid message, through a valid DL packet, the IUT shall act

42、ivate the corresponding indicator. This assumes the proper receipt of the physical signal. The test operator will evaluate the correct reception of the message, and consequently of the physical signal, by observing the reaction of the IUT. The fiial reaction of the IUT is provoked by then presentati

43、on layer message, itself correctly embedded in a DL packet. So that to proceed with this test method, a valid Presentation layer message and a valid DL packet shall be chosen. These are generic parameters to be defined before execution of the test purpose, and according to the feature of the IUT. Tw

44、o generic data layer signals are defiied in the On-hook and in the Off-hook clauses. The following messages are some examples of generic presentation layer messages, which can be used to execute the physical and DL test purposes; either: - a minimum content Message Waiting Indicator message (MWI) wi

45、th only the mandatory parameters contained in that message; this MWI is selected first since it should lead to the easiest detection through the Visual Indicator (odofij; or a minimum content Call Set Up for the calling line identity presentation; or - ETSI 13 FSK data (generic) ETSI ES 200 778-4 VI

46、 .I .2 (2002-1 1) First ring pattern - a minimum content Short Message Service (SMS) message; or - NOTE: a minimum content Advice of Charge message. Other “generic“ messages may need to be created for testing in the cases where the IUT supports only one very particular service such as Alarm Call. 5.
