This International Standard specifies the Path Replacement additional network feature (ANF-PR), which is applicable to
various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in
ISO/IEC 11574.
ANF-PR is a feature which applies to an established call, allowing that call's connection between Private Integrated Services
Network Exchanges (…

This International Standard specifies the 8-contact connector (plug and jack) and the assignments of its contact
numbers for use in the physical interfaces of Integrated Services Digital Network (ISDN) primary rate access
services conforming to ITU-T Recommendation I.431.
In this International Standard, as in ITU-T Recommendation I.431, the term "NT" is used to indicate the network…

This International Standard is a part of the functional requirements for the Private Integrated Services Network (PISN)
and defines the functions and procedures that are required by Private Integrated Services Network exchanges (PINXs)
and the intervening network (IVN) in order to establish Inter-PINX Connections (IPC). The IPC is used for the transfer
of signalling and user information between…

This Recommendation | International Standard defines the management domain and management policy management
function. This Management Function is a System Management function which may be used by an application process in a
centralized or decentralized management environment to interact for the purpose of systems management, as defined by
the OSI Management Framework, CCITT Rec. X.700 and ISO/IEC…

Acoustics — Determination of sound absorption coefficient and impedance in impedance tubes — Part 2:...
This test method covers the use of an impedance tube, two microphone locations and a digital frequency analysis system for the determination of the sound absorption coefficient of sound absorbers for normal sound incidence. It can also be applied for the determination of the acoustical surface impedance or surface admittance of sound absorbing materials. Since the impedance ratios of a sound…
