Introduction
Line and circuit testing of analogue and ISDN lines is part of a management activity which is performed by the operator
in order to detect failure conditions and to bring the customer access back to its normal state of operation whenever a
deviation occurs.
A customer access is considered as being that part of the local network which extends from the network termination
equipment up to and including the exchange termination.
Here, only these parts of the activity are covered which are related directly to that part of the customer access which
extends from the LE to the network termination equipment. An ISDN access extends to but does not include the
T reference point. An analogue access extends to and may include the Customer Premise Equipment (CPE)
(see figure 1).

NOTE: Shaded areas are subject to line and circuit testing. User ports represent the different configurations for

Figure 1: Scope of line and circuit testing
The present document details only those functions and management information model components which are required
for line and circuit testing. However, the use of other components which may be applicable from other specifications is
not precluded. In this case, combined applications incorporating line and circuit test specific and more generic aspects
would result.

1 Scope
The present document specifies the Q3 interface between an Local Exchange (LE) and the Telecommunications
Management Network (TMN) for the support of line and circuit test functions for analogue and ISDN lines which are
connected directly to a LE.
The focus of the present document is on defining an object model based on the existing standards ETS 300 378-1 [3]
and ITU-T Recommendation X.745 [20]. The add-ons, modifications and restrictions to these standards are specified
which are necessary to adapt the object model to a LE. Existing protocols are used where possible. The definition of
Operations System (OS) functionality is outside the scope of the present document.

4.1.1 Line testing and line circuit testing
Test requests from the OS are sent as Common Management Information Protocol (CMIP) testRequestControlled or
testRequestUncontrolled action to an instance of testActionPerformer. In this model, all controlled tests are delegated by
instances of testActionPerformer to instances of subclasses of testObject, i.e. when receiving a test request the
testActionPerformer automatically creates the required instances of these classes. Further instances of subclasses of
testObject are created if further delegation of the performance of the test is required. This creation is achieved by
sending additional testRequestControlled actions, the testSessionId parameter is used to identify in which access test
instance the new tests should be contained. All instances of these subclasses of testObject exist only for the duration of
their delegated operations. Details of the mechanism how to transmit test requests to testActionPerformer and how test
results are generated are described in ITU-T Recommendation X.745 [20].
Management information related to uncontrolled tests can be found in annex B.
Controlled testing is initially delegated to an instance of accessTest or to an instance of loopTest or to an instance of
metallicTestAccess. Each instance of loopTest or accessTest or metallicTestAccess is contained in an instance of
testActionPerformer.
The object class loopTest is used to set up loopbacks for the user port to which it is associated by an attribute. If patterns
are to be injected and compared within the LE as part of the loopback test, then this is delegated to an instance of
patternTest which is contained in the delegating instance of loopTest.
The object class accessTest has all specific non-loopback tests allocated to it. It has an attribute which specifies one or a
list of user ports which are to be tested.
If external test systems are used for line testing, the metallicTestAccess allows to connect it to each subscriber line
(outbound or bridged) and to each line circuit (inbound) of the LE. The implementation of the metallic test access is
outside the scope of this standard.
The creation of an instance of accessTest represents a test session and permits test access to lines or line circuits during
which a number of different tests can be performed. These delegated tests are handled by specific contained test objects.
Each contained test object triggers the specific test on one or more user ports which are specified in accessTest.
Electrical measurements, such as voltage, capacitance and resistance, are delegated to instances of
electricalMeasurementTest. Dialled digit tests, dial tone tests and other tests (in particular those involving sending meter
pulses to the line, cable pair identification tone and ringing) are triggered by the creation of instances of
dialledDigitTest, dialToneTest, spmPulses, cablePairIdTone and ringing, respectively. The dry loop condition is set up
by instances of dryLoopTest. The inward line circuit tests are delegated to instances of testToLineCircuit. The
voiceAccessTest allows for the provision of those test which involve the establishment of a voice connection with the
line under test. A quick check of an ISDN access is represented by a isdnQuickTest object.
The object class testThresholdClass can be used to modify predefined test thresholds via the Q3 interface.
4.1.2 The testResultNotifications of the tests
The sending time, the information contents and the number of testResultNotifications sent per test request are not
restricted. It is a matter up to the LE implementation. If the testResultNotification contains results whose testing time has
importance, they shall be ordered in the ASN.1 sequence oldest first.

5 Information model description
This clause provides a high-level informal description of the management information model for line and circuit testing
in the LE.
Subclause 5.1 contains a brief description for each object class or package used in the model as far as it is not described
in the reference documents. The description covers:
- the purpose of the object class or package;
- the attributes defined for the object class or package;
- the contents of the event reports defined in the present document;
- the relationship of the object class to other object classes;
- the applicability of these packages.
Attributes which are common to several object classes are described in subclause 5.2. Subclause 5.3 describes actions
which are common to several object classes in the information model. Subclause 5.4 describes the common aspects of
the notifications used in the information model.
5.1 Description of object classes
5.1.1 Access port fragment
In this fragment the following object classes are used. They are used in the test operations to identify the MORTs. They
are defined in I-ETS 300 291 [1]:
- "I-ETS 300 291":analogueAccess;
- "I-ETS 300 291":basicRateAccess;
- "I-ETS 300 291":primaryRateAccess.
