SIST ETS 300 455-1 E1:2003 is a SIST standard that adopts ETS 300 455-1 Edition 1 for Broadband Integrated Services Digital Network (B-ISDN), Broadband Virtual Path Service (BVPS), Part 1: BVPS for Permanent communications (BVPS-P). It specifies stage 1 for a semi-permanent virtual path bearer service in B-ISDN, describing how the service is offered, subscribed to, and characterized for public telecommunication operators and their users.

What does SIST ETS 300 455-1 E1:2003 specify?

SIST ETS 300 455-1 E1:2003 specifies the stage 1 service description of BVPS-P for B-ISDN. In practice, that means it defines the service from the user and provider viewpoint: what the service is, how it is subscribed to, how it behaves in operation, and which service attributes apply.

The document covers permanent communications only, while ETS 300 455-2 covers BVPS-R for reserved communications. It also includes interworking requirements with other networks that connect to B-ISDN, and it places the service in the stage 1 / stage 2 / stage 3 framework used for telecommunication service characterization.

Its main structure is:

• Clause 1 Scope
• Clause 2 Normative references
• Clause 3 Definitions, symbols and abbreviations
• Clause 4 Description
• Clause 5 Procedures
• Clause 6 Interworking
• Clause 7 Interaction with supplementary services
• Clause 8 Static description of the service using attributes

What are the key requirements of SIST ETS 300 455-1 E1:2003?

SIST ETS 300 455-1 E1:2003 defines BVPS-P as a point-to-point, two-way communication service based on Asynchronous Transfer Mode (ATM) Virtual Path (VP) connections in B-ISDN. For implementation, this means the service is not a general packet service - it is a specific bearer service with a fixed service model.

Clause 4 states that the service carries unrestricted digital information in ATM cells, with cell sequence integrity, and that the source traffic can be Constant Bit Rate (CBR) or Variable Bit Rate (VBR). The practical point is that user traffic is accepted as ATM-cell-based information, but the source rate must remain within the subscribed Peak Cell Rate (PCR).

Clause 4 also states that statistical multiplexing cannot be used for BVPS-P, and that the Service Provider (SP) allocates resources using the PCR value. This matters because capacity planning is based on reserved service parameters, not shared statistical pooling.

Clause 5 separates provision and withdrawal, normal procedures, and exceptional procedures. Subscription is arranged in advance with the SP, and the document distinguishes non-periodic VPs from periodic VPs. For a buyer or network planner, this means the contract must specify whether a VP is continuous or follows a repeating schedule.

For a non-periodic VP, Clause 5.1.1 requires agreement on the users’ ISDN numbers, VPIs, subscription beginning time, symmetry, and PCR, with subscription end time and QoS as optional parameters. For a periodic VP, Clause 5.1.2 adds the period and the start and end of each time slot, with PCR and QoS able to vary by slot. In practice, this is the part that defines the service order and the operating timetable.

Clause 5.2 defines activation and deactivation behavior. A non-periodic VP is available throughout the subscription period, while a periodic VP is activated and deactivated at the times set for each slot. The document also allows a periodic deactivation to be simultaneous with the next activation so that service continues without a drop to zero.

Clause 8 gives the static service attributes: ATM transfer mode, connection-oriented operation, unrestricted digital information capability, permanent establishment, point-to-point configuration, and three VP symmetry options - unidirectional, bi-directional symmetric, and bi-directional asymmetric. It also states that the QoS is based on performance parameters from ITU-T Recommendation I.356.

What terms does SIST ETS 300 455-1 E1:2003 define?

• Asynchronous Transfer Mode (ATM) - the cell-based transfer mode used by the service.
• Broadband Virtual Path Service for Permanent communications (BVPS-P) - the service defined by this standard for permanent or semi-permanent communication.
• Peak Cell Rate (PCR) - the maximum cell rate associated with each VP.
• Peak Emission Interval (PEI) - a timing parameter used with PCR conformance.
• Cell Delay Variation (CDV) - the allowed variation in cell arrival timing.
• Service Management Entity (SME) - the functional entity that receives registration, modification, and interrogation requests.
• Virtual Path Identifier (VPI) - the local identifier for a specific VP at a User-Network Interface (UNI).

Who uses SIST ETS 300 455-1 E1:2003?

SIST ETS 300 455-1 E1:2003 is intended for European public telecommunication operators, Service Providers (SPs), and engineers working on B-ISDN and ATM-based services. It is also relevant to equipment suppliers and network planners who need to implement VP-based access, subscription handling, and interworking at the UNI.

In practice, users apply it when defining service contracts, provisioning permanent VP connections, checking subscription parameters such as PCR and QoS, and aligning B-ISDN service behavior with stage 2 and stage 3 standards.

Which standards are used with SIST ETS 300 455-1 E1:2003?

The standard relies on several referenced ITU-T, CCITT, and ETS documents:

• CCITT E.164 - numbering plan for ISDN numbers.
• ITU-T I.112 / I.113 - vocabulary for ISDN and broadband ISDN terms.
• CCITT I.130 / ITU-T I.140 - service characterization and attribute technique.
• ITU-T I.150 / I.361 - ATM functional characteristics and ATM layer specification.
• ITU-T I.356 / I.371 - ATM cell transfer performance and traffic/congestion control.
• ITU-T M.3010 - telecommunications management network principles.
• ETS 300 299 / ETS 300 300 - standardized physical layer access for B-ISDN.
• ETS 300 455-2 - the companion part for BVPS-R, reserved communications.

What does the SIST ETS 300 455-1 E1:2003 document contain?

The document contains a service description, subscription procedures, timing schedules, and attribute-based characterization for BVPS-P. Clause 5 includes the detailed subscription model for non-periodic and periodic VPs, including mandatory and optional parameters, and Figures 1 and 2 illustrate the timing logic for provision and repeating time slots.

It also gives the service definition terms used in the text, the ATM-related access and traffic attributes, and the references needed to interpret the service in the wider B-ISDN framework. For implementers, the useful parts are the subscription parameters, the PCR and QoS handling, the activation/deactivation rules, and the service attribute list in Clause 8.

1 Scope
This European Telecommunication Standard (ETS) defines the stage 1 of the Broadband Virtual Path
Service for Permanent communications (BVPS-P) for a Broadband Integrated Services Digital Network
(B-ISDN), as provided by European public telecommunication operators.
Part 2 of this ETS (ETS 300 455-2 [13]) defines the stage 1 of the Broadband Virtual Path Service for
Reserved communications (BVPS-R) for a Broadband Integrated Services Digital Network (B-ISDN), as
provided by European public telecommunication operators.
This ETS does not specify the additional requirements where the service is provided to the user via a
telecommunication network that is not a B-ISDN, but it does include requirements for interworking of other
networks with a B-ISDN.
This ETS is applicable to stage two and stage three standards for the BVPS-P. The terms "stage two" and
"stage three" are also defined in CCITT Recommendation I.130 [4]. Where the text indicates the status of
a requirement (i.e. as strict command or prohibition, as authorisation leaving freedom, or as a capability or
possibility), this shall be reflected in the text of the relevant stage two and stage three standards.
Furthermore, conformance to this ETS is met by conforming to the stage three standards with the field of
application appropriate to the equipment being implemented. Therefore, no method of testing is provided
for this ETS.
Charging principles and management operations are outside the scope of this ETS.
The BVPS-P provides the transfer of unrestricted digital information between T .or S /T reference
B B B
points. It does not preclude the applicability of the BVPS-P to S .
B
The provision of the BVPS-P is based on the use of Asynchronous Transfer Mode (ATM) Virtual Path (VP)
connections in a B-ISDN.
