SIST ETS 300 012/A1 E1:2003 is the Slovene version of ETS 300 012/A1 Edition 1. It is an amendment to the ISDN basic user-network interface Layer 1 specification and test principles, so it updates how Layer 1 behavior is specified and how related tests are performed for terminal equipment and network termination.
What does SIST ETS 300 012/A1 E1:2003 specify?
SIST ETS 300 012/A1 E1:2003 specifies amendments to the published ETS 300 012 Layer 1 standard for the Integrated Services Digital Network (ISDN) basic user-network interface. In practice, it changes selected figures, tables, test clauses and state tables that are used to verify interface behavior and power-related operation.
The amendment is organized as a foreword, a list of amendments, and a history note. The changes touch the main text and the annex material used for TE and NT testing.
| Annex | What it covers in this amendment |
|---|---|
| Annex A | TE-related requirements and test entries, including power detection, INFO wording, and pulse unbalance |
| Annex D | TE test procedures, state tables, polarity, framing, jitter, and power condition tests |
| Annex E | NT test procedures, polarity, framing, and test configurations |
What are the key requirements of SIST ETS 300 012/A1 E1:2003?
This amendment mainly tightens how Layer 1 tests are set up and how results are interpreted. The practical effect is that manufacturers and test labs must use the revised figures, state tables and stimulus/result definitions when checking ISDN user-network interface behavior.
TE-related changes
- Figure 3 updates the TE power start-up test. This matters because power-on behavior is part of interface conformance, especially for locally powered equipment and phantom-powered operation.
- Figure 7 updates the test circuit for applied current unbalance. That affects how imbalance is measured and therefore how the test setup must be wired.
- Annex A, A.5.3.2 adds a disconnect detector requirement for TEs using the automatic assignment procedure. In practice, a TE must detect power source 1 or 2 to establish connection status.
- Annex A, A.6.2.6.1 changes the wording from INFO2 to INFO2 or INFO4. This broadens the accepted signal conditions in that test entry.
- Annex A, A.8.5.4 is marked Informative (I) for pulse unbalance. That tells the reader this entry is explanatory rather than a direct compliance requirement.
Test-state and stimulus updates
- Annex D, D.3.2.1 revises the TE activation state table, including extra notes for locally powered TEs and disconnected detectors. For testing, this means the tester must watch state transitions carefully when power disappears, when the interface signal changes, and when the TE is expected to remain idle until the interface voltage stays below 24 V for a defined time.
- D.3.2.2.1.1 changes the polarity integrity test in state F3 so it uses INFO2 frames and is performed with both normal and reversed polarity. This is a direct setup instruction for polarity testing.
- D.3.3 revises the framing-loss and framing-regain results. The practical point is that the test outcome is judged by specific frame-error patterns and by whether framing is regained in the allowed sequence.
- D.4.2 and D.4.5.2 update jitter-measurement and power-related TE test text, including a defined deactivated-to-synchronised test state sequence.
- D.5.1.4.2 updates the current/time limitation test for TE when connecting. This is relevant for equipment design because it checks how the TE behaves during connection under restricted power conditions.
NT-related changes
- Annex E, E.1.4.4 maps polarity integrity to the detailed test in E.3.3.2.1.
- E.3.3.2.1, Test B uses INFO3 from the TE simulator and requires both normal and reversed polarity. This keeps the NT polarity test aligned with the interface direction being exercised.
- E.3.4 revises framing-loss and framing-regain results for the NT test sequence.
- E.5.1.4.3, E.5.1.7, and E.6.1.5 update test configurations involving mains supply and load changes. These changes matter when the NT is verified under changing supply and load conditions.
What terms does SIST ETS 300 012/A1 E1:2003 define?
- ISDN - Integrated Services Digital Network, the service and interface family covered by the standard.
- TE - Terminal Equipment, the user-side equipment that is tested against the Layer 1 rules.
- NT - Network Termination, the network-side equipment used in the NT test clauses.
- IUT - Item Under Test, the device or setup being exercised in a test.
- INFO 0 - A Layer 1 signal condition used in the state and framing tests to represent deactivation-related behavior.
- INFO 2 / INFO 4 - Layer 1 signal conditions used in activation, synchronization and polarity-related tests.
- PH-AR - Physical layer activation request, used in the state machine tables.
- PS1 / PS2 - Power source 1 and power source 2, which are important for locally powered TEs and power detection.
Who uses SIST ETS 300 012/A1 E1:2003?
SIST ETS 300 012/A1 E1:2003 is used by telecommunications engineers, test laboratories, and manufacturers of ISDN terminal equipment and network termination equipment. Quality teams and conformity assessment staff use it to set up Layer 1 tests, interpret state transitions, and verify power, polarity, framing and jitter behavior on the user-network interface.
What changed in SIST ETS 300 012/A1 E1:2003 from the previous edition?
SIST ETS 300 012/A1 E1:2003 is Amendment 1 to ETS 300 012 (1992). The amendment replaces or updates figures, tables and subclauses covering power start-up, current unbalance, automatic assignment, polarity integrity, framing, jitter measurement, power conditions, and current/time limitation for TE and NT tests. The history note also records the first edition of ETS 300 012 in April 1992 and Amendment 1 in December 1994.
Which standards are used with SIST ETS 300 012/A1 E1:2003?
This amendment is used with ETS 300 012 (1992), which it modifies. Several amended test clauses also refer back to subclauses of ETS 300 012, so the base standard is needed to use this amendment correctly.
What does the SIST ETS 300 012/A1 E1:2003 document contain?
The document contains replacement figures for TE power start-up, current unbalance, and several mains-supply test configurations. It also contains revised state tables, test stimuli, result criteria, and cross-references for the TE and NT Layer 1 test clauses.
The annex material is used for design checks, laboratory testing, and conformance work on ISDN basic user-network interface equipment. The changes mainly tell the reader how to build the test setup, what stimulus to apply, and how to judge the observed state or frame result.
