Overview

SIST EN 300 392-5 V2.2.1:2010 is the TETRA (Terrestrial Trunked Radio) standard part that defines the Peripheral Equipment Interface (PEI) for Voice plus Data (V+D) and Direct Mode Operation (DMO). It updates EN 300 392-5 for TETRA Release 2 PEI and incorporates agreed change requests. The document specifies the functional and technical aspects of the interface between a Terminal Equipment type 2 (TE2) and a Mobile Termination type 2 (MT2) at reference point RT, enabling consistent connectivity and service control across TETRA terminals and peripheral devices.

Key topics and technical requirements

The standard covers protocol, physical and control-layer requirements that guarantee interoperability and predictable behavior of TETRA PEI implementations. Major technical topics include:

• Protocol architecture and context model - structural view of PEI layers and context handling between TE2 and MT2.
• SDS (Short Data Service) message stacks and types - definitions for status, SDS types 1–4 and message text handling.
• AT command set and command states - standardized AT/V.250 and extended commands for call control, PEI control and generic MT control, including syntax, responses and state transitions (AT command, circuit mode data, TNP1/packet data).
• TNP1 and IP network layer - packet data operation, IP addressing, local and wide modes and TNP1 behavior.
• Physical layer specifications - wired interfaces (V.24/V.28 electrical/character format/data rates), wire-line high-rate technologies (USB, USB On-The-Go), and wireless high-rate options (Bluetooth, Certified Wireless USB) including security considerations.
• Operational procedures - link start-up at MT, phone book handling, SDS-TL considerations, reserved status values and interoperability limits.

The document also includes normative and informative references, symbols/abbreviations and detailed command descriptions such as modified cellular commands (+GCAP, +CREG, +CNUM).

Practical applications and users

This standard is essential for:

• Terminal and peripheral equipment manufacturers - to implement PEI-compliant firmware and hardware for TETRA terminals.
• System integrators and OEMs - to ensure reliable device interoperability in public safety, utilities, transportation and critical-communications deployments.
• Test labs and certification bodies - to create conformance and interoperability test suites against PEI behaviors and AT/packet data handling.
• Network operators and procurement teams - to specify PEI requirements in RFPs and validate device compliance for TETRA V+D and DMO services.

Adopting SIST EN 300 392-5 PEI ensures predictable TETRA interoperability, streamlined peripheral integration (USB/Bluetooth/V.24) and correct handling of voice, short data and packet data services.

Related standards

• ETSI/EN 300 392 series (TETRA V+D and DMO) - other parts cover air interface, call control and system features.
• Relevant telecommunications interface standards (V.24/V.28, V.250) referenced for serial and AT-command behavior.
