1  ScopeWord‑p. 7

The present document specifies for Mobile Stations (MS), for the digital cellular communications system and Personal Communication Systems (PCS) operating in the 900 MHz and 1800 MHz band (GSM900 and DCS1800), standardized by 3rd Generation Partnership Project (3GPP), those ME functions which are required for conformance testing purposes only. However, except for the Electrical Man Machine Interface (EMMI) and the Multi-slot TCH Loops, they are required for every mobile station.
For conformance tests, functions are activated via the radio interface, test SIM or dedicated pins. These functions must be capable of being activated when a test SIM is present but must not function with any other (e.g. network) SIM present except where otherwise stated within the present document. In this state, the MS must be able to perform all functions specified in the present document; in addition however, the special conformance testing functions must be operational.
The special conformance testing functions of the ME are enabled by use of a dedicated Subscriber Identity Module (test SIM, see TS 51.010-1 Annex 4). SIM, in general, is described in TS 51.011. The ME recognizes the test SIM by the Administrative Data Field.
The present document applies to the public land mobile radio service in the GSM900 and DCS1800 systems, using constant envelope modulation and operating on radio frequencies in the 900 and 1800 MHz bands respectively with a channel separation of 200 kHz and carrying 8 full rate channels or 16 half rate channels per carrier according to the TDMA principle.
The present document is part of the 3GPP TS series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM related TS, nor is it created to provide full understanding of (or parts of) the GSM900 and DCS1800 systems.
The present document applies to the unit which includes the hardware to establish a connection across the radio interface.

1.1  Conventions |R8|

Unless explicitly stated otherwise, the following conventions apply:
  • "EGPRS" refers to "EGPRS and EGPRS2".
  • "EGPRS2" refers to "EGPRS2-A and EGPRS2-B".

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
  • References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
  • For a specific reference, subsequent revisions do not apply.
  • For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

3  Definitions, conventions, and applicabilityWord‑p. 8

For abbreviations and acronyms, see TR 21.905.

3.1  Mobile station definition and configurations

In the present document, a MS can be:
  • a vehicle mounted station;
  • a portable station;
  • a handheld station;
  • a vehicle mounted/portable station;
  • a vehicle mounted/handheld station.
For a more detailed description of MS-configurations, see TS 22.101.

3.2  Applicability

The present document is applicable to all MSs.

4  Activation and deactivation of special test functions in the MS

The functions described in the present document can be activated and deactivated from a SS by sending appropriate layer 3 commands to the MS. The protocol discriminator to be used is defined in TS 44.018, subclause 10.2.
The layer 3 commands are sent on the DCCH. On layer 2, SAPI 0 is used in acknowledged mode.
Apart from sending the appropriate deactivation command to the MS the functions can be deactivated by switching off the MS or removing the test SIM.
The following test functions can be activated (and deactivated):
  • TCH Loop;
  • TCH Burst-by-Burst Loop;
  • Multi-slot Loop;
  • Electrical MMI;
  • Test via DAI.
  • Reset MS Positioning Stored Information (activation only)
The TCH loops and the test via DAI are test functions which are mutually exclusive.
