1 Scope
This part 4 of ETS 300 012 provides the test principles for the requirements of this ETS used to determine
the compliance of an Implementation Under Test (IUT) to this ETS.
It is outside the scope of this ETS to identify the specific tests required by an implementation where
equipment has to meet attachment approval.
Detailed test equipment accuracy and the specification tolerance of the test devices is not a subject of this
ETS. Where such details are provided then those test details are to be considered as being an
"informative" addition to the test description.
Unless otherwise stated, conformance tests described in this ETS do not apply to the Auxiliary Power
Supply (APS).
This ETS is applicable to interface I . The field of applicability is reported at the beginning of each test.
A
Ideal values for components and circuits are considered in the test principles.
Details concerning connection cords and general testing requirements can be found in annex A of this
ETS.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS the following definitions, together with those given in annex E of
ITU-T Recommendation I.430 [7] and in ITU-T Recommendation I.411 [6] apply:
basic access: A user-network access arrangement that corresponds to the interface structure composed
of two B-channels and one D-channel. The bit rate of the D-channel for this type of access is 16 kbit/s.
B-channel: This function provides for the bidirectional transmission of independent B-channel signals
each having a bit rate of 64 kbit/s.
bearer service: A type of telecommunication service that provides the capability for the transmission of
signals between user-network interfaces.
NOTE 1: The ISDN connection type used to support a bearer service may be identical to that
used to support other types of telecommunication service.
connection management entity: An entity for the purpose of management of resources that have an
impact on an individual data link connection.
D-channel: This function provides for bidirectional transmission of one D-channel signal at a bit rate of
16 kbit/s.
designated terminal: A terminal which is permitted to draw power from power source 1 under both
normal and restricted power conditions.
frame alignment: This function provides information to enable the TE or NT to recover the time-division
multiplexed channels.
Integrated Services Digital Network (ISDN): A network that provides or supports a range of different
telecommunications services and provides digital connections between user-network interfaces.
interface I : User side of the ISDN user-network interface for the basic access.
A
interface I : Network side of the ISDN user-network interface for the basic access.
B
Network Termination (NT): An equipment providing interface I .
B
NOTE 2: This term is used in this ETS to indicate network-terminating aspects of NT1, NT2 and
PS1 functional groups where these have an I interface.
B
Network Termination type 1 (NT1): This functional group includes functions broadly equivalent to layer 1
(physical) of the Open Systems Interconnection (OSI) reference model. These functions are associated
with the proper physical and electromagnetic termination of the network. NT1 functions are:
- line transmission termination;
- layer 1 maintenance functions and performance monitoring;
- timing;
- power transfer;
- layer 1 multiplexing;
- interface termination, including multidrop termination;
- employing layer 1 contention resolution.
---------------------- Page: 12 ----------------------
SIST ETS 300 012-4 E2:2003
Page 11
ETS 300 012-4: October 1998
Network Termination type 2 (NT2): This functional group includes functions broadly equivalent to layer 1
and higher layers of the ITU-T Recommendation X.200 [8] reference model. Private Automatic Branch
Exchanges (PABXs), Local Area Networks (LANs), and terminal controllers are examples of equipment or
combinations of equipment that provide NT2 functions. NT2 functions include:
- layer 2 and 3 protocol handling;
- layer 2 and 3 multiplexing;
- switching;
- concentration;
- maintenance functions;
- interface termination and other layer 1 functions.
non-designated terminal: A terminal which is only permitted to draw power from power source 1 under
normal power conditions.
normal power condition: The condition indicated by the normal polarity of the phantom voltage at the
access leads, i.e. where the voltage of the transmit leads c and d on the TE is positive with respect to the
voltage on the receive leads e and f.
Power Source 1 (PS1): Power source for the provision of remote power feeding of TE via a phantom
circuit of the interface wires.
restricted power condition: The condition indicated by the reversed polarity of the phantom voltage at
the access leads, i.e. where the voltage of the receive leads e and f on the TE is positive with respect to
the voltage on the transmit leads c and d.
simulator: Device generating the stimulus signal for the IUT and monitoring the signal transmitted by the
IUT to find the result.
Terminal Adapter (TA): An equipment with interface I and one or more auxiliary interfaces that allow
A
non-ISDN terminals to be served by an ISDN user-network interface (see also
ITU-T Recommendation I.411 [6]).
Terminal Equipment (TE): An equipment with interface I and consisting of one or more functional
A
blocks.
NOTE 3: This term is used in this ETS to indicate terminal-terminating aspects of TE1, TA and
NT2 functional groups, where these have an I interface.
A
Terminal Equipment Type 1 (TE1): This functional group includes functions belonging to the functional
group TE, and with an interface that complies with the ISDN user-network interface recommendation.
