Overview

ETSI EN 300 392-5 V2.5.1 (2016-10) (ETSI EN 300 392-5) defines the Peripheral Equipment Interface (PEI) for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) and Direct Mode Operation (DMO). The standard specifies the functional and technical aspects of the interface between a Terminal Equipment type 2 (TE2) and a Mobile Termination type 2 (MT2) at the reference point RT. It ensures consistent behaviour, signalling and data exchange so peripheral devices and terminals interoperate reliably across vendors and deployments.

Key topics and technical requirements

  • Protocol architecture & context model - describes PEI layers, states and the interactions required for voice, data and control services.
  • Message types: SDS & Status - definitions and handling of Short Data Service (SDS) message stacks, reserved status values and text formats.
  • AT command set - comprehensive AT command syntax, parameters, responses, result codes and state transitions for call control and PEI management (including modified V.250 commands).
  • Physical layer and connectivity - supported physical interfaces and electrical characteristics (e.g., V.24/V.28), plus wire-line and wireless high-rate connectivity technologies such as USB, USB On-The-Go, Bluetooth and Certified Wireless USB.
  • TNP1 and IP network layer - packet-data transport, IP addressing modes, local and wide modes and TNP1 operational details for IP-enabled services.
  • Link startup and state machines - procedures for MT link startup, AT command state, circuit mode data and packet data transitions.
  • Phone book and user data handling - storage and access models for contact data used by terminals.
  • Security & operational considerations - guidance on wireless security and implementation considerations for secure PEI operation.
  • Normative references to standards such as V.24/V.28 and V.250 where applicable.

Practical applications and users

  • Equipment manufacturers implementing TETRA TE2/MT2 interfaces to ensure cross-vendor interoperability.
  • Firmware and driver developers for terminals, data modules and accessories that use the PEI (e.g., rugged terminals, vehicle kits).
  • System integrators deploying TETRA-based public safety, transport, utilities and industrial communications who require consistent device behaviour.
  • Test labs and certification bodies validating compliance with TETRA V+D / DMO PEI requirements.
  • Network operators and procurement teams specifying device compatibility and performance requirements.

Related standards

  • ETSI EN 300 392 series (TETRA V+D and DMO family)
  • ITU-T recommendations referenced in the document (e.g., V.24/V.28, V.250)
  • Vendor-specific implementation guides and certification test suites aligned with ETSI requirements

This standard is essential for reliable implementation of the TETRA PEI-ensuring secure, interoperable voice and data services across TETRA terminals and peripheral equipment.
