Foreword
This amendment to Technical Basis for Regulation (TBR) has been produced by ETSI Project Digital
Terminals and Access (DTA).
This amendment should be considered as an urgent technical correction.
This amendment has been produced at the request of the Approvals Committee for Terminal Equipment
(ACTE) and:
- contains amendments to the requirements as determined by the special group of the ISDN Type
Approval Advisory Ad-Hoc Group (ITAAAG) in order to align with the "essential requirements"
according to Directive 91/263/EEC;
- contains corrections to reported shortcomings in the Tree and Tabular Combined Notation (TTCN)
at Layers 1, 2, and 3;
- contains TTCN in ISO International Standard (IS) form in place of the Draft ISO International
Standard (DIS) form;
- deselects tests declared by the special group of ITAAAG as being not essential according to
Directive 91/263/EEC;
- contains a complete replacement of the TBR-RT (tables of annex A). The ETSI BTC2-TE5 joint
meeting to discuss the results of the UAP decided to give preference to a complete replacement of
the TBR-RT instead of an amendment of at least each second table which could lead to confusion
to the user of the document.
NOTE: The references to the changed pages in the standard refer to an old presentation. See
history box at the end of the standard itself.
The new presentation format, applied from 1 December 1995, may have different page
numbering. The clause numbering has not changed.

Amendments
Page 16, subclause 3.1
Amend definition as indicated:
designated terminal: A terminal which is permitted to draw power from Power Source 1 (PS1) under both
normal and restricted power conditions in the absence of any other power source.
non-designated terminal: A terminal which is only permitted to draw power from Power Source 1 (PS1)
under normal power conditions in the absence of any other power source.
Page 37, subclause 9.2.7
Amend the line below the figure 9.7 as indicated:
The Longitudinal Conversion Loss: LCL = 20 log |E /V | dB
10 L T
The voltages V and E should be measured within the frequency range from 10 kHz up to 300 KHz
T L
1 MHz using selective test voltage measuring equipment.
Page 43, subclause 9.4.2.1.1
Amend definition as indicated:
Definition: In this inactive (powered off) state, the TE is not transmitting and cannot detect the presence
of any input signals. In the case of locally powered TEs which cannot detect the
appearance/disappearance of PS1, this state is entered when local power is not present. For locally
powered TEs that can detect PS1, state F1.0 is entered whenever loss of local power (required to support
all TEI functions) is detected, and state F1.1 is entered when the absence of power from PS1 is detected
and local power is available.No requirements are applicable for locally powered TEs for absence of PS1.
Page 45, subclause 9.4.2.3.1
Insert note and amend test as indicated:
Requirement: A TE which is powered from PS1 shall follow the procedures described in the finite state
matrix table shown in table 9.7.
A TE which is locally powered and does not have a connection detector capable of detecting the presence
of PS1 shall follow the procedures described in the finite state matrix table shown in table 9.8.
A TE which is locally powered and has a connection detector capable of detecting the presence of PS1
shall follow the procedures described in the finite state matrix table shown in table 9.9.
NOTE: Where requirements are not subject for testing in all possible states, the corresponding
behaviour is implicitly checked in the tests for other states.
Test: The test shall be conducted according to annex B, TTCN test cases AD1aF1_PS&_LP_-on,

Table 9.7 (concluded): Activation/deactivation Layer 1 finite state matrix table for
TEs powered from PS1
NOTE 1: This event reflects the case where a signal is received which is not INFO 2 or INFO 4. To
ensure that a TE takes appropriate action when receiving a signal to which it cannot
synchronize, operation of TEs should be verified where the received signal is any bit pattern
(containing at least three ZEROs in each frame interval) to which TEs conforming to
subclause 9.4.3 are not able to synchronize. In the TTCN test cases in annex B, clause B.4,
this signal is called INFO X.
NOTE 2: If more than one power feeding source can be used as declared in items 1 and 2 of annex A,
table A.1, the reaction of the TE may be different from that described. It may be necessary
then to analyse the behaviour of the TE, when tested according to annex B, clause B.4, and
when powered as declared by the supplier (see annex E, table E.2).
NOTE 3: Two responses are possible. Either:
a) the TE shall enter state F5 within 5 ms. Where this option is implemented by the
TE, the requirements associated with state F5 are applicable; or
b) on receipt of INFO 2, the TE shall enter state F6 within 5 ms; and on receipt of
INFO 4, the TE shall enter state F7 within 5 ms, stop and reset timer T3, and
send PH-AI. Where this option is implemented by the TE, the requirements
associated with state F5 are not applicable.
NOTE 4: The timer T4 shall be started when leaving state F7 or F8 upon the reception of INFO 0. The
corresponding PH-DI will be delivered to Layer 2 only, if Layer 1 does not re-enter an active
state before expiry of this timer. The value of this timer is in the range of 500 ms to 1 000 ms.
This prevents the loss of an on-going communication caused by spurious effects.
NOTE 5: INFO 0 shall be detected when 48 or more contiguous binary ONEs have been received and
the TE shall perform the actions specified in table 9.7. Conformance shall be tested with a
sinusoidal signal having a voltage of 100 mV peak-to-peak (with a frequency in the range of
2 kHz to 1 000 kHz, preferably 100 kHz). TE being in state F6 or F7 shall react on receipt of
this signal by transmitting INFO 0 within a period of time 250 μs to 25 ms.

Table 9.8 (concluded): Activation/deactivation Layer 1 finite state matrix table for locally powered
TEs unable to detect PS1
NOTE 1: This event reflects the case in which a signal is received which is not INFO 2 or INFO 4. To
ensure that a TE takes appropriate action when receiving a signal to which it cannot
synchronize, operation of TEs should be verified where the received signal is any bit pattern
(containing at least three ZEROs in each frame interval) to which TEs conforming to
subclause 9.4.3 are not able to synchronize. In the TTCN test cases in annex B, clause B.4,
this signal is called INFO X.
NOTE 2: The term power could be the full operational power or backup power. Backup power is
defined such that it is enough to hold the TEI values in memory and maintain the capability of
receiving and transmitting Layer 2 frames associated with the TEI procedures. If more than
one power feeding source can be used as declared in items 1 and 2O.1.2 of annex A,
table A.13.2, the reaction of the TE may be different from that described. It may be
necessary then to analyse the behaviour of the TE, when tested according to annex B,
clause B.4, and when powered as declared by the supplier (see annex E, table E.2).
NOTE 3: Two responses are possible. Either:
a) the TE shall enter state F5 within 5 ms. Where this option is implemented by the
TE, the requirements associated with state F5 are applicable; or
b) on receipt of INFO 2, the TE shall enter state F6 within 5 ms; and on receipt of
INFO 4, the TE shall enter state F7 within 5 ms, stop and reset timer T3, and
send PH-AI. Where this option is implemented by the TE, the requirements
associated with state F5 are not applicable.
NOTE 4: The timer T4 shall be started when leaving the states F7 or F8 upon reception of INFO 0.
The corresponding PH-DI will be delivered to Layer 2 only, if Layer 1 does not re-enter state
F7 before expiry of this timer. The value of this timer is in the range of 500 ms to 1 000 ms.
This prevents the loss of on-going communication caused by spurious effects.

taken shall be the same as if a DISCONNECT message with Cause #31 "normal, unspecified" was
received (see subclause 11.4.3).
When a RELEASE COMPLETE message is received with a Cause information element missing, it shall
be assumed that a RELEASE COMPLETE message was received with Cause #31 "normal, unspecified".
Test: This requirement shall be tested according to the procedures of annex D, test cases TC10015,
TC10115, TC10222, TC11028 and TC11029.
NOTE: No test for the action on receipt of a DISCONNECT message with the Cause
information element missing is specified in this version of the TBR because it was not
possible to develop and verify a test due to shortage of time and resources. ETSI
intends to develop and verify an appropriate test for inclusion in a later version.

Amend text as indicated:
Requirement: When a message is received which has one or more unrecognized information elements,
the TE shall check whether any are encoded to indicate "comprehension required" (refer to table 11.27 for
information element identifiers reserved with this meaning). If any unrecognized information element is
encoded to indicate "comprehension required", then the procedures in subclause 11.4.6.5.1 are followed;
i.e. as if a "missing mandatory information element" error condition had occurred. If all unrecognized
information elements are not encoded to indicate "comprehension required", then the TE shall proceed as
follows.
Action shall be taken on the message and those information elements which are recognized and have
valid content. When the received message is other than DISCONNECT, RELEASE or RELEASE
COMPLETE, a STATUS message may be returned containing one Cause information element. The
STATUS message shall indicate the Call state of the receiver after taking action on the message. The
Cause information element shall contain Cause #99 "information element non-existent or not
implemented", and the diagnostic field, if present, shall contain the information element identifier for each
information element which was unrecognized.
Subsequent actions are determined by the sender of the unrecognized information elements. If a clearing
message contains one or more unrecognized information elements, the error is reported to the local TE in
the following manner:

a) when a DISCONNECT message is received which has one or more unrecognized
information elements, a RELEASE message shall be returned;
-b) when a RELEASE message is received which has one or more unrecognized
information elements, a RELEASE COMPLETE shall be returned;
c) when a RELEASE COMPLETE message is received which has one or more
unrecognized information elements, no action shall be taken on the unrecognized
information.
Test: This requirement shall be tested according to the procedures of annex D, test cases TC10027,
