3GPP TS 44.014 version 13.1.0 Release 13 7 ETSI TS 144 014 V13.1.0 (2016-08)
1 Scope
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
rd
by 3 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 3GPP TS 51.010-1 Annex 4). SIM, in general, is described in 3GPP 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
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 applicability
For abbreviations and acronyms, see 3GPP TS 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 3GPP 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 3GPP TS 44.018, sub-clause 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;
