Description (English):

ISO/IEC 15053:2003 specifies Additional Network Feature Call Interception (ANF-CINT), which is applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. ANF-CINT is an additional network feature which enables calls that cannot be completed due to certain conditions to be redirected to a pre-defined intercepted-to user. ANF specifications are produced in three stages, according to the method described in ETS 300 387. ISO/IEC 15053:2003 contains the stage 1 and stage 2 specifications of ANF-CINT. The stage 1 specification (clause 6) specifies the feature as seen by users of PISNs. The stage 2 specification (clause 7) identifies the functional entities involved in the feature and the information flows between them.

Abstract

Overview

ISO/IEC 15053:2003 - Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Call Interception additional network feature (ANF‑CINT) - defines how a Private Integrated Services Network (PISN / PINX) performs call interception. The standard specifies stage 1 (user-visible behaviour) and stage 2 (functional model and information flows) for ANF‑CINT. It describes when calls that cannot be completed under certain conditions are redirected to a pre‑defined intercepted‑to user, and what notifications and functional interactions are required.

Key topics and technical requirements

Scope: ANF‑CINT applies to basic services defined in ISO/IEC 11574 and is a PISN‑instigated Additional Network Feature (ANF).
Staged specifications:
- Stage 1 (clause 6) - feature seen by users: invocation conditions, parameters (e.g., intercepted‑to number), notification rules, activation/registration behaviour.
- Stage 2 (clause 7) - functional model: functional entities (FEs), information flows, FE actions and behaviour, allocation to physical equipment.
Invocation conditions / interception causes (implementation options include): busy user, no reply (timeout during alerting), incoming barred destination, invalid number, network congestion, route restriction, mobile user not registered, call transfer timeouts, and others.
Interception modes:
- Immediate interception - redirect when a precluding condition is detected before alerting/waiting.
- Delayed interception - redirect after a timeout in alerting or waiting on busy; PISN may retain the called leg until intercepted‑to user alerts.
Notification requirements:
- The intercepted‑to user must be notified of interception cause and called number/name if available.
- The calling user must be informed the call was intercepted and, where allowed (subject to CLIR/CNIR), receive intercepted‑to user identity.
Conformance: To claim conformance to ISO/IEC 15053:2003, a stage 3 standard (signalling protocols / equipment behaviour) must support the relevant aspects of clauses 6 and 7.

Applications and who uses it

PISN / PBX vendors implementing private telephony features (ANF‑CINT) for enterprises.
Telecom equipment manufacturers and system integrators designing call control, redirection and supplementary‑service interworking.
Network operators and service designers specifying interception behaviour for attendants, call centres, security routing, and emergency handling.
Standards developers creating stage 3 signalling protocols and conformance test suites.

Related standards

ISO/IEC 11574 (basic services / basic call model)
ISO/IEC 11579‑1 (PISN reference configuration)
ISO/IEC 11571 (PISN addressing)
ETS 300 387 (method for ANF specification)
Relevant ITU‑T recommendations (I.112, I.210, I.221, Z.100)

This concise specification is essential when you need standardized behaviour, functional decomposition and information‑flow models for call interception in private integrated telephony networks.
