• Abstract:

  To produce a further versions of the ATM Forum AF-CS-0125.000 AINI endorsement as contained in EN 301 814-1 to include addendas produced by ATM Forum. This should also include the text of EN 301 902 as normative annex and then EN 301 902 should be withdrawn.

SIST EN 301 814 V1.2.2:2005 is the Slovenian adoption of ETSI EN 301 814 V1.2.2, an ETSI endorsement of the ATM Forum ATM Inter-Network Interface (AINI) signalling specification. It specifies stage three signalling for AINI and the protocol interworking needed to connect PNNI- and B-ISUP-based ATM networks. The document also carries additional endorsement material for Unspecified Bit Rate with Minimum Desired Cell Rate (UBR with MDCR).

What does SIST EN 301 814 V1.2.2:2005 specify?

SIST EN 301 814 V1.2.2:2005 specifies how AINI is used to set up, maintain, and clear ATM connections between ATM networks. It is a modified endorsement of ATM Forum Specification ATM Inter-Network Interface (AINI) F-CS-0125.000 (1999), and the scope also says it carries forward EN 301 814-1 with addenda from ATM Forum and includes EN 301 902 as a normative annex.

The document is organized around the endorsement text in the main clauses, plus normative annex material for additional signalling capability. Annex A covers UBR with MDCR endorsement notice, while the former informative material is moved into Annex E1 and Annex E2.

Annex	What it covers

What are the key requirements of SIST EN 301 814 V1.2.2:2005?

The core requirement is stage three AINI signalling for interworking between PNNI and B-ISUP based ATM networks. In practice, this means the standard is concerned with call and connection signalling across network boundaries, not with local network operation alone.

AINI scope and interworking

Clause 1.1 says the AINI signalling protocol is for interconnecting ATM networks that run PNNI internally with networks that run B-ISUP internally. It also supports interworking between two networks that both run PNNI internally. The document explicitly limits this interworking to AINI, PNNI and B-ISUP - other protocol interworking is outside its scope.

Connection handling

The AINI capabilities are limited to dynamically establishing, maintaining, and clearing ATM connections. For users of the standard, this means the signalling focus is on connection lifecycle control rather than on traffic transport details.

Capability support in the option set

Clause 1.2 makes support for at least one of table 1-1 items 13 or 14 mandatory. The same clause also requires the SAAL to use the assured mode of transfer; unacknowledged mode is only allowed by bilateral agreement. In practice, implementers need to check their feature profile and signalling transport behavior before claiming conformance.

UBR with MDCR over AINI

Annex A adds signalling for UBR with MDCR across the AINI interface. It treats UBR with MDCR as an optional feature of AINI and requires a device that supports it to implement the procedures for point-to-point calls/connections, and for point-to-multipoint calls/connections when those are supported.

Switch behavior for MDCR

Annex A says a switch supporting the UBR with MDCR feature at AINI shall be able to forward the MDCR information element. It may also generate a network-generated MDCR information element. This matters for network design and interworking tests because the MDCR data has to survive signaling exchange correctly.

What terms does SIST EN 301 814 V1.2.2:2005 define?

AINI (ATM Inter-Network Interface) is the signalling interface used to interconnect ATM networks, especially when different internal signalling systems have to interwork.

PNNI is the ATM signalling environment used on one side of the interworking; the standard uses AINI to connect networks running PNNI internally.

B-ISUP is the other internal ATM signalling environment named by the standard; AINI defines how it interworks with B-ISUP-based ATM networks.

SAAL is the signalling adaptation layer used by the document, and the standard requires the assured mode of transfer unless both sides agree otherwise.

UBR (Unspecified Bit Rate) is the service category extended in Annex A by MDCR signalling.

MDCR (Minimum Desired Cell Rate) is the information element carried or generated for UBR with MDCR procedures.

Who uses SIST EN 301 814 V1.2.2:2005?

This standard is for telecom engineers, network equipment vendors, and operators working with ATM signalling and interworking. It is also relevant to quality managers and buyers evaluating ATM switching or gateway equipment, because it describes the signalling features a product claims to support. The UBR with MDCR annex is especially relevant where point-to-point and point-to-multipoint ATM connection behavior has to be specified, implemented, or tested.

What changed in SIST EN 301 814 V1.2.2:2005 from the previous edition?

The foreword says the document was renumbered from EN 301 814-1 to EN 301 814 after work on a separate testing specification was stopped. The endorsement notice also adds ATM Forum signalling capability endorsements, and Annex A introduces the UBR with MDCR endorsement notice with its related procedures and scenarios moved into informative Annex E1 and Annex E2.

Which standards are used with SIST EN 301 814 V1.2.2:2005?

The document cites ITU-T Recommendation I.130 as the basis for the stage three service characterization used in the scope description. It also cites ITU-T Recommendation Q.2110, which provides the SSCOP service-specific connection-oriented protocol used for the assured mode of transfer on SAAL.

The standard is itself an ETSI endorsement of ATM Forum Specification ATM Inter-Network Interface (AINI) F-CS-0125.000 (1999), modified. Annex A is based on UBR with MDCR Addendum to UNI Signalling 4.0, PNNI 1.0 and AINI AF-CS-0147.000 (2000-07).

What does the SIST EN 301 814 V1.2.2:2005 document contain?

The document contains the endorsement notice, the modified scope text, the normative reference list, and the annex that adds UBR with MDCR signalling. It also includes the relocated informative material for UBR with MDCR overview and MDCR scenarios.

Clause 1 sets the AINI scope and the transport-related constraints. Clause 5 is the references section, and Annex A applies additional signalling procedures for a specific ATM service category. The document is practical for implementation, interoperability checking, and network equipment specification rather than for testing tables or numerical performance values.
