Overview
SIST EN 300 659-1 V1.3.1:2003 is a European standard specifying the subscriber line protocol for on-hook data transmission over analogue lines in the Public Switched Telephone Network (PSTN). Published by the Slovenski inštitut za standardizacijo (SIST), this standard enables support for display services such as Calling Line Identification Presentation (CLIP) by defining precise requirements for data transmission between the local exchange (LE) and terminal equipment (TE) when the line is in the on-hook state.
This protocol forms the foundation for advanced telephony features that leverage analogue PSTN infrastructure, ensuring interoperability and consistent service quality across networks and devices.
Key keywords: PSTN, subscriber line protocol, analogue access, on-hook data transmission, display services, Calling Line Identification Presentation, frequency-shift keying (FSK), DTMF.
Key Topics
On-hook Data Transmission:
Specifies methods for transmitting information from the network (LE) to the subscriber device (TE) while the telephone is on-hook, enabling value-added services such as CLI and related display features.Protocol Layers:
Defines requirements at the presentation layer (message format and encoding), data link layer (bit error detection, channel seizure, mark signal), and physical layer (modulation/demodulation based on ITU-T V.23).Data Transmission Techniques:
- FSK (Frequency-Shift Keying): Main method for message encoding and delivery, ensuring data integrity and compatibility.
- DTMF (Dual Tone Multi-Frequency): Supported for legacy networks, allowing the continuation of existing subscriber line protocols.
Transmission Modes:
- Associated with Ringing: Data sent during or prior to ringing, with precise timing intervals to guarantee terminal compatibility.
- Unassociated with Ringing: Supports operator-selected transmission outside active call setup and alerting signals.
Signaling and Timing:
Requirements for alerting signals (DT-AS, RP-AS, line reversal) and their physical characteristics, ensuring that TE reliably detects and processes incoming data.Pair Gain and Access Networks:
Special considerations are given for implementations involving access networks or pair gain systems to ensure compatibility and correct timing.
Applications
Caller ID and CLI Services:
Enabling the delivery of calling line identification and other call-related information to analogue Te.Display Services:
Support for various information display capabilities, such as number presentation, special messages, or service-related notifications.Enhanced Telephony Devices:
Telephone manufacturers, exchange and network operators apply this standard to provide enhanced PSTN services, leveraging on-hook message delivery for customer information and supplementary features.Interoperability:
Ensures that equipment from different vendors can reliably exchange signalling and data over analogue local loops, critical for broad service rollout in public telephone networks.
