DEVELOPMENT OF TECHNICAL CODES

The Communications and Multimedia Act 1998 (‘the Act’) provides for Technical Standards Forum designated under section 184 of the Act or the Malaysian Communications and Multimedia Commission (‘the Commission’) to prepare a technical code. The technical code prepared pursuant to section 185 of the Act shall consist of, at least, the requirement for network interoperability and the promotion of safety of network facilities.

Section 96 of the Act also provides for the Commission to determine a technical code in accordance with section 55 of the Act if the technical code is not developed under an applicable provision of the Act and it is unlikely to be developed by the Technical Standards Forum within a reasonable time.

In exercise of the power conferred by section 184 of the Act, the Commission has designated the Malaysian Technical Standards Forum Bhd (‘MTSFB’) as a Technical Standards Forum which is obligated, among others, to prepare the technical code under section 185 of the Act.

A technical code prepared in accordance with section 185 shall not be effective until it is registered by the Commission pursuant to section 95 of the Act.

FOREWORD

This technical code for the Specification for Short Range Devices (SRD) (‘this Technical Code’) was developed pursuant to section 185 of the Act 588 by the Malaysian Technical Standards Forum Berhad (MTSFB) via its Wireless Terminal Working Group.

This Technical Code was developed for the purpose of certifying communications equipment under the Communications and Multimedia (Technical Standards) Regulations 2000.

This Technical Code is the first revision of SKMM WTS SRD Rev. 1.01:2007, Technical Specification for Short Range Device.

This Technical Code cancels and replaces SKMM WTS SRD Rev. 1.01:2007.

This Technical Code shall continue to be valid and effective until reviewed or cancelled.

SPECIFICATION FOR SHORT RANGE DEVICES (SRD)

1. Scope

This Technical Code defines the technical requirements for SRD transmitters and receivers operating in the frequencies as defined in the relevant Standard Radio System Plans (SRSPs) and the Class Assignments issued by MCMC.

SRD may be fixed, mobile or portable stations that come with a radio frequency output connector and dedicated antenna or an integral antenna. Its applications include (but not limited to) short range communication (SRC), remote control, security, wireless microphone, wireless local area network (WLAN), industrial, scientific and medical (ISM), radio frequency identification (RFID) and wireless CCTV. The devices may employ different types of modulation and power requirement which may include data, video and voice application.

2. Normative references

The normative references in Annex A are indispensable for the application of this Technical Code. For dated references, only the edition cited applies. For undated references, the latest edition of the normative references (including any amendments) applies.

The devices shall be tested for compliance with the applicable technical requirements stipulated in Clause 4 and Table 1 of this Technical Code. The test methods and conditions mentioned in Table 1 shall be applicable to the device under test.

3. Abbreviation

For the purposes of this Technical Code, the following abbreviation applies.

Section A

Introduction

1. Scope

1.1. This Technical Code identifies the minimum technical requirements for connecting to the Integrated Services Digital Network (ISDN) at the S/T interface using Basic Access (BA). It also identifies the requirements for the digital transmission system at the network side of the Network Termination (NT1) forming part of the ISDN BA.

1.2. ISDN BA equipment connected to the S/T interface (see Figure 1) shall have e it h e r Terminal Equipment Type 1 (TE1) or Terminal Adaptor (TA) function incorporated. For such equipment, suppliers shall demonstrate that it has been tested to comply with the requirements defined in Section A, B, C and D of this Specification.

Section B – Physical layer requirements based on ITU-T Rec. I.430, Basic Rate User- Network - Interface Layer 1 Specification Section C – Link Access Procedure on the D-channel, LAPD based on ITU-T Rec. Q.921, ISDN User-Network Interface - Data Link Layer Specification Section D – Network layer requirements based on EN 300 403-1 11/99, Integrated Services Digital Network (ISDN): Digital Subscriber Signaling System No. One (DSS1) protocol: Signaling network layer for circuit-mode basic call control; Part 1: Protocol Specification [ITU-T Recommendation Q.931 (1993), modified].

1.3 If the ISDN BA equipment has the NT1 function built-in, suppliers shall demonstrate that it has been tested to comply with the requirements defined in Section A, B, C, D as well as Section E.

1.4. If the NT1 function is standalone, suppliers shall demonstrate that the NT1 equipment has been tested to comply with the requirements defined in Section A and E. Section E defines the digital transmission system at the network side of the NT1, and is based on the ITU-T Rec. G.961. The digital transmission system shall use line codes and transmission methods given in Appendix II of the ITU-T Rec. G.961. References to ETSI ETR 080 are given for information only. The TE side of the NT1 shall conform to the network requirements of the ITU-T Rec. I.430.

2. Normative references

The normative references as in Annex A are indispensable for the application of this Technical Specification. For dated references, only the edition cited applies. For undated references, the latest edition of the normative references (including any amendments) applies.

CR Conformance Requirement defines features and functions that must be supported at minimum. M Mandatory requirement is where the TE implementation shall conform to those clauses in that section relating to the operation of Layer 1, Layer 2 and Layer 3 protocol in the TE. O Optional requirement means it is optional whether TE implements that function but if function is implemented, it shall conform to the clauses in that section relating to the operation of the TE Layer 1, Layer 2 and Layer 3 protocol.

However, the use of optional functions is possible only if the network operators have implemented these options in their networks. NA Not Applicable is where the requirements specified in that section on the TE shall not be applicable for attachment. GID The section provides General Information and Definitions. TE1 ISDN-capable terminal equipment e.g.: Digital phone and digital fax TE2 Non-ISDN equipment e.g: Analogue phone and the RS-232 serial port on computer TA Terminal adapter that interface the TE2 devices with ISDN network NT1 Network terminator that reside between telco’s network and customer equipment NT2 An intelligent device that can perform switching function e.g: PABX and Local Area Network (LAN)

1. Introduction

This section contains clarification and recommended option selections for the ETSI ISDN standards and technical reports related to basic call control procedures of ISDN basic and primary access signaling. This document covers the basic call control of layers 1, 2 and 3. The aim of this document is to avoid unnecessary options and vagueness in ISDN implementations and to ensure the interoperability of ISDN networks and terminal equipment in Malaysia.
