PURPOSE. This Instruction: Implements references (a) and (b). Provides policy, procedures, and assigns responsibilities for test, certification, accreditation, lease or procurement, installation, connection, and operation of telecommunications switches, switched data, and services on DoD...
This Recommendation works on the assumption that Voice over LTE (VoLTE) is a so-called ''managed'' voice service, in opposition to over the top (OTT) applications without use of session initiation protocol/IP multimedia subsystem (SIP/IMS) signalling and with no prioritized traffic....
This Recommendation focuses on the required functions and procedures necessary for support of narrow-band voice services by MPLS networks. ITU-T Rec. Y.1261 [1] describes the service requirements and architecture for transport of voice services over MPLS networks....
The present document defines addressing for Terrestrial Trunked Radio system (TETRA) supporting Voice plus Data (V+D). It also gives background information of the air interface, the interworking between TETRA systems and to other systems via gateways, the terminal equipment interface on the...
The PSTN transition from a TDM-based network to an IP-based network has and will continue to impact many facets of the networks. For this reason, it was decided to assess this transition with regards to network availability. This document covers reporting metrics,...
Scope & Purpose The purpose of this Standard is to facilitate a TSP's compliance with the assistance capability requirements defined in Section 103 of CALEA [Ref 1]. This Standard defines capabilities to support LAES and the interfaces to deliver intercepted communications and reasonably available...
The present document is applicable to any TETRA terminal equipment (Mobile Station (MS)) and to any TETRA network (Switching and Management Infrastructure (SwMI)) which support at least one TETRA Supplementary Service (SS). In addition, its routeing requirements of supplementary service...
This Recommendation presents the requirements for signalling collecting, signalling network analyses and signalling network optimization in a voice over LTE (VoLTE) network. The signalling network refers to the network entities and the signalling exchange...
This part of IEC 60793 is applicable to category A4 optical multimode fibres and the related subcategories A4a, A4b, A4c, A4d, A4e, A4g, A4h and A4i. These fibres have a plastic core and plastic cladding and may have step-index, multi-step index or graded-index profiles. The fibres are used in...

This standard shall identify the operating environment parameters, as well as the minimum requirements for the design, performance, testing, and certification of portable RF voice communications devices (RF devices) and remote speaker microphones (RSMs) for use by emergency services...
This Recommendation1 specifies a framework in the form of constraints, performance criteria and methods for the development of intrusive parametric, machine learning (ML) based models for the assessment of transmission network impact on speech quality for mobile packet-switched voice...
This report provides an overview of the activities designed to produce and implement measures to mitigate both the scourge of illicit robocalling and the falsification of originating party identities that support it. This report begins by defining the real problems to be solved: specifically, how...
The present document defines the Terrestrial Trunked Radio (TETRA) system supporting Voice plus Data (V+D). It specifies: • the interworking of individual calls between TETRA networks; • the supplementary services interaction with individual calls between TETRA networks. The...
