SIST ETS 300 087 E1:2003

SIST ETS 300 087 E1:2003 is the Slovenian standard identical to ETS 300 087 Edition 1. It specifies the functional characteristics of Group 4, Class 1 facsimile equipment for attachment to the Integrated Services Digital Network (ISDN), so manufacturers, test labs, and buyers can see what an ISDN fax terminal must support in practice.

What does SIST ETS 300 087 E1:2003 specify?

SIST ETS 300 087 E1:2003 covers Group 4 Class 1 facsimile functionality for ISDN attachment, with a focus on interoperability between terminals that exchange image-coded information. The scope is limited to black-and-white images, circuit-switched ISDN at basic and primary rate access, Transport layer procedure T.70 Section 5, Session control procedures T.62 or T.62bis, Class B documents of the Formatted Document Architecture (FDA), and centre line page referencing.

The document does not cover packet-switched ISDN, PSTN, CSPDN, PSPDN, Class A FDA, basic Teletex documents, or other page-referencing schemes.

The standard is organized into clauses on scope, normative references, abbreviations, general requirements, general characteristics, reproducible area, maximum receiving time, optional group 3 aspects, use and management, and extended features. Annex A is informative and gives a bibliography.

What are the key requirements of SIST ETS 300 087 E1:2003?

SIST ETS 300 087 E1:2003 sets a common baseline by requiring compliance with the related CCITT recommendations and ETSI standards named in Clause 4. In practice, this ties the terminal to the ISDN lower layers, coding, transport, and document-profile rules used by the rest of the group 4 facsimile family.

Terminal behavior

• The equipment shall provide automatic reception, so a received call can be handled without manual intervention.
• Synthesizing the document to be transmitted is allowed instead of physical scanning, but a terminal without a scanner must accept input from a physical scanner.
• A printer is optional, but every terminal shall be able to output a received document to a printer.
• If the document is shown on a display, the whole page does not need to appear at once, but the user shall be able to move through the rest of the document.

Identification and call information

• Each terminal shall support insertion of identification data.
• The terminal shall allow entry of the called terminal address and/or number, and the mnemonic part is optional.
• Mnemonic matching is case-insensitive and must match sequentially from the start, which helps prevent sending to the wrong destination.
• Terminal identification can be installed either by authorized downloading or by authorized introduction.
• The Call Identification Line (CIL) shall use date and time from the network when available, or from the terminal clock and calendar otherwise; presenting the CIL is optional.

Page area and performance

• Clause 6 fixes the scanning track and the reproducible area, so the transmitted image and any CIL fit within defined page limits.
• Clause 7 sets a maximum receiving time for an electronically synthesized “slerexe letter” at 200 pels resolution, giving a concrete timing target for receive-side performance.

Operation and extended features

• The terminal shall restore operability automatically after a power failure.
• If an activity log is provided, it shall be chronological, without gaps, and include the CIL for each sent or received document.
• The user shall be warned when ABORT or DISCARD is received at the session layer.
• Extended-feature configurations add a required activity log, message waiting indication, and special rules for facsimile messages stored in volatile memory.

What terms does SIST ETS 300 087 E1:2003 define?

SIST ETS 300 087 E1:2003 defines its abbreviations in Clause 3 so the document can use them consistently.

• Call Identification Line (CIL) - the date and time line associated with a facsimile transmission or reception.
• Integrated Services Digital Network (ISDN) - the network to which the facsimile equipment attaches.
• Formatted Document Architecture (FDA) - the document architecture used here only for Class B facsimile documents.
• Circuit Switched Public Data Network (CSPDN) - a public data network type outside the scope of this standard.
• Packet Switched Public Data Network (PSPDN) - another public data network type excluded from the covered attachment cases.
• Public Switched Telephone Network (PSTN) - the switched telephone network that is not covered by this ISDN facsimile specification.

Who uses SIST ETS 300 087 E1:2003?

SIST ETS 300 087 E1:2003 is used by designers and manufacturers of Group 4 Class 1 facsimile terminals, by conformance and interoperability test labs, and by network or service providers that support facsimile services on ISDN. Procurement and quality teams use it to check basic compatibility, reception behavior, identification handling, logging, and extended-feature behavior before acceptance.

What changed in SIST ETS 300 087 E1:2003 from the previous edition?

SIST ETS 300 087 E1:2003 corresponds to ETS 300 087 Edition 1, and the standard history identifies it as the first edition.

Which standards are used with SIST ETS 300 087 E1:2003?

SIST ETS 300 087 E1:2003 relies on the following named standards and recommendations:

• CCITT Recommendation T.563 - terminal characteristics for group 4 facsimile equipment.
• CCITT Recommendation T.6 - facsimile coding schemes and coding control functions.
• CCITT Recommendation T.70 - network-independent basic transport service.
• CCITT Recommendation T.62 and T.62bis - session control procedures.
• CCITT Recommendation T.412 and T.417 - document structures and raster graphics content architectures.
• CCITT Recommendation T.503 - document application profile for group 4 facsimile interchange.
• CCITT Recommendation T.521 - communication application profile BTO for document bulk transfer.
• CCITT Recommendation T.90 - characteristics and protocols for terminals for telematic services in ISDN.
• ETS 300 080 - ISDN lower layer protocols for telematic terminals.
• ETS 300 112 - end-to-end protocols for group 4 class 1 facsimile on the ISDN.
• ETS 300 155 and ETS 300 280 - related testing documents named in the foreword and bibliography.
• ETS 300 156 - cited for primary rate access to the Telefax 4 Service.

What does the SIST ETS 300 087 E1:2003 document contain?

SIST ETS 300 087 E1:2003 contains the functional specification for the equipment, the supported operating limits, and the service-management behavior expected from Group 4 Class 1 facsimile on ISDN. It also defines the reproducible area, the presentation of the Call Identification Line, the receiving-time limit, and the behavior after power failure or session-layer abort/discard conditions.

Annex A provides a bibliography for related ISDN and facsimile documents, including NET 3, NET 5, and the associated testing standards.
