NOTE 1: Because the IUT can be powered in different ways, it is
     useful to test this IUT with the possible power it is able to
     detect (PS1, PS2, local power).
NOTE 2: T3 = Implementation dependent, not to exceed 30 sec.
NOTE 3: "Any signal" is simulated by any bit pattern on which the IUT
     conforming to subclause A.6.3.1.2, ETS 300 012 is not able to
     synchronise.
NOTE 4: For testing purposes INFO 0 is simulated by a sinusoidal
     signal having a voltage of 100 mV peak to peak (with a
     frequency in the range of 2 kHz to 1000 kHz). The TE shall
     react by transmitting INFO 0 within a period time 250 μs to
     25 ms.
NOTE 5: The PH-DI corresponding to the reception of INFO 0 shall be
     delivered to Layer 2 only if Layer 1 does not re-enter an
     active state before the expiration of a timer of which the
     value is in the range of 500 ms to 1 s.
NOTE 6: Applicable only for TEs which are locally powered and able to
     detect PS1 or PS2.
NOTE 7: If INFO 2 of INFO 4 is not recognised within 5 ms after the
     appearance of a signal, TE shall go to F5. The result is to
     be tested 5 ms after generation of the stimulus.
NOTE 8: For TEs which are locally powered and able to detect PS1 or
     PS2, at the event "disappearance of power" in states F6 or
     F7, no state change shall be observed.
NOTE 9: Locally powered TEs with disconnected detector shall not
     assume disconnection and shall not take any action until the
     voltage of the interface has remained below 24 V for at least
     500 ms (refer to subclause 7.1.1).

F.2 PICS proforma for interface point I (TE)
a
F.2.1 Introduction
To evaluate conformance of a particular implementation, it is necessary to have a statement of which
capabilities and options have been implemented for a given protocol. Such a statement is called a PICS. A
client who requests a conformance test shall provide to the test laboratory a completed PICS proforma for
each OSI layer to be tested.
This clause defines the PICS proforma applying to the OSI layer 1 (physical layer) of equipment having
interface Ia (see § 4.4 of CCITT Recommendation I.430 [2]) for the connection to the ISDN basic access
at reference points S or S/T (coincident S and T) (see CCITT Recommendation I.411 [1]) and intended to
be installed on customers premises.
NOTE: In addition to the information provided by a PICS, information relating to the
implementation and its testing environment is essential. Such extra information is
called a PIXIT. Generally PIXIT proforma are produced and provided by the test
laboratory.
The PIXIT proforma provided in clause F.3 should be used.
F.2.2 PICS proforma structure and contents
The PICS proforma consist of tables structured as indicated in references ISO/IEC 9646-1 [19] and
ISO/IEC 9646-5 [20].
F.2.3 Pre-printed table contents
The pre-printed contents of the PICS tables provide the following:
- table/item identification, see subclause F.2.4;
- item names or short descriptions;
- references to the standards;
NOTE: For this ETS, references refer to rows of table A.1 of ETS 300 012, unless otherwise
indicated.
- status attributes specifying the status of the items;
- predicates, see "c" below;
- column to be filled in by the client, see subclause F.2.5.
The status attribute in the "Status" column reflects the conformance requirements defined in the
referenced standard as follows:
m (mandatory): the capability is required to be implemented, in conformance with the protocol
specification. When a mandatory capability is not supported, it is a case of non-
conformance, and the client shall give a justification (see subclause F.2.5).
o (optional): the capability may be implemented, and if it is implemented it is required to
conform to the protocol specification.
c (conditional): the requirement on the capability depends on the selection of other optional or
conditional items; the PICS proforma cannot define in advance a definite status
for the capability, it can only indicate that the status depends on the evaluation
of a predicate. The predicates are indicated in the table column "Predicate" or in
the last table row as item notes.
- (dash): not applicable item, i.e. no requirement can be expressed in a given context.

F.2.4 Table/item identification
The PICS table is provided with a table/item identification label pre-printed to the left in the table headers.
The labels are composed as follows:
- one capital letter, being the first letter of the layer name;
- a serial number.
Each item in a PICS table is provided with a serial number in the left-hand table column, called "Item No."
To identify an item unambiguously, the table label and the item number are combined by use of a slash
character, "/", e.g. in the 2nd table of the Physical layer PICS, the 3rd item is identified by "P2/3".
F.2.5 Filling in guidance
The filling in is done in the rows of right table column named "Support" as follows:
- for implemented items one of: Y, y, Yes, yes or YES is entered;
- for not implemented items one of: N, n, No, no or NO is entered.
For each not implemented mandatory item, the client shall give a justification, e.g. as an added note
associated with the item.
