1 Scope
This European Telecommunication Standard (ETS) 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.
Part 1 of this ETS (ETS 300 455-1 [13]) defines the stage 1 of the Broadband Virtual Path Service for
Permanent communications (BVPS-P) for a 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-R. 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-R 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-R to S .
B
The provision of the BVPS-R is based on the use of Asynchronous Transfer Mode (ATM) Virtual Path
(VP) connections in a B-ISDN.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
Asynchronous Transfer Mode (ATM): See ITU-T Recommendation I.113 [3], definition 204.
broadband: See ITU-T Recommendation I.113 [3], definition 101.
Cell Delay Variation (CDV) tolerance: The CDV tolerance τ corresponds to the maximum anticipated
time variation with respect to the Theoretical Arrival Time, see ITU-T Recommendation I.371 [9],
subclause 2.4.1.1.
Global Virtual Path Identifier (GVPI): The GVPI identifies a specific Virtual Path (VP). It is used by the
Service Management Entity (SME) for the management of the complete VP.
initiating manager: The manager issuing a request to the SME.
Integrated Services Digital Network (ISDN): See ITU-T Recommendation I.112 [2], definition 308.
involved manager: The manager receiving a request issued by another initiating manager.
ISDN number: A number conforming to the numbering plan and structure specified in CCITT
Recommendation E.164 [1].
manager: The functional entity authorised to send through x reference point (as defined in ITU-T
Recommendation M.3010 [10]) the VP registration requests, VP modification requests and interrogation
requests, on behalf of the users to which it is related at the subscription time (see figure A.1).
non-periodic VP: A non-periodic VP is a VP whose values of PBR and Quality of Service (QoS) are
constant for the reservation duration.
Peak Cell Rate (PCR): See ITU-T Recommendation I.371 [9], subclause 2.4.1.1. The PCR is expressed
as an integer number of cells per second.
Peak Emission Interval (PEI): See ITU-T Recommendation I.371 [9], subclause 2.4.1.1.
periodic VP: A periodic VP is a VP whose same scheme of the values of PBR and QoS repeats within
each period for the reservation duration.
service, telecommunication service: See ITU-T Recommendation I.112 [2], definition 201.

Service Management Entity (SME): The SME is the functional entity to which manager’s VP registration
requests, VP modification requests and interrogation requests are addressed (see figure A.1).
subscriber: The entity that subscribes to the BVPS-R.
time slot: The time interval between the activation and the following deactivation of a VP. The duration of
th
an i time slot De is defined by De = De + M x P where De is the minimum duration of the time
i i min i min
slot, M is an integer and P is a fixed duration of time. De and P are service constants.
i min
user: Each of the subscriber's functional entity that sends or receives ATM cells through T or S T
B B/ B
reference point (see figure A.1).
Virtual Channel (VC): See ITU-T Recommendation I.113 [3], definition 401.
Virtual Channel Identifier (VCI): A logical number that locally identifies a specific VC at the
User-Network Interface (UNI).
Virtual Path (VP): From the user's point of view, a virtual end-to-end connection that ensures
unidirectional or bi-directional transport of ATM cells belonging to VCs that are associated by a common
VPI at each UNI.
Virtual Path Identifier (VPI): A logical number that locally identifies a specific VP at the UNI.
