i 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 Commissi on’) 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.

1 SPECIFICATION FOR AS YMMETRIC DIGITAL SUB SCRIBER LINE (ADSL) 
TRANSCEIVERS  
 
 
1. Scope  
 
1.1 This Technical Code  defines the physical layer characteristics of the Asymmetrical Digital 
Subscriber Line (ADSL) transceivers. The purpose of the specification is to ensure proper inter -
working of ADSL transceivers at the customer end (ATU -R) and network operator end (ATU -C) in 
terms of interaction, electrical characteristics and ADSL interoperability. It defines a variety of frame 
bearers in connection with or without an underlying service. For example:  
 
a) ADSL transmission simultaneously on the same pair with voice band service; and  
 
b) ADSL transmission without any underlying service, optimized for deployment with ADSL over 
voice band service in the same binder cable.  
 
1.2 ADSL Transceivers shall  be designed for multi -mode operation, supporting one or more of the 
following ADSL Transceivers standards:  
 
a)  ADSL Transceivers (ITU -T Rec. G.992.1) outlined in Section A;  
 
b)  Splitterless ADSL Transceivers (ITU -T Rec. G.992.2) outlined in Section B;  
 
c)  ADSL2 Transceivers (ITU -T Rec. G.992.3) outlined in Section C;  
 
d)  Splitterless ADSL2 Transceivers (ITU -T Rec. G.992.4) outlined in Section D;  
 
e)  ADSL2+ Transceivers – Extended Bandwidth (ITU -T Rec. G.992.5) outlined in Section E; and  
 
f)  ADSL Interoperability Test Plan (DSL Forum Technical Report TR -067) Section F.  
 
1.3 ADSL Transceivers, supporting the ADSL2, Splitterless ADSL2 or ADSL2+ standards  shall be 
backward compatible and capable of interacting with network equipment which supports only the 
ADSL and Splitterless A DSL standards.  
 
1.4 The ADSL interoperability test plan facilitates ADSL over POTS and ISDN CPE/DSLAM 
interoperability testing. This test plan embodies operators’ definitions of ADSL interoperability 
(between one DSLAM and one CPE at a time). The test plan  focuses on physical layer testing, and 
also validation and verification of selected higher layer functionality. The test plan defines dynamic 
interoperability (performance) as expected by leading carriers, specifying simulated network 
conditions under whi ch interoperability is required. The performance points in this test plan are based 
on ATU -C equipment, capable of providing the maximum allowable power.  
 
ATU-C equipment unable to provide this transmit power is considered to be out of the scope of this 
interoperability test plan.   
 
This test plan defines tests for various physical layer functionalities and some higher layer 
functionalities.

Notes:  
 
i) U-C and U -R interfaces are fully defined in this Technical Specification.  
ii) V-C interface may consist of interfaces to one or more ATM switching systems.  
iii) High-pass (HP) filters, which are part of the splitters,  may be integrated into the ATU -x; if so, U -C2 and U -R2 will become 
the same as U -C and U -R interfaces, respectively.  
iv) Due to asymmetry of signals on the line, transmitted signals shall be distinctively specified at the U -R and U -C reference 
points.  
v) T/S may  interface to in -building Ethernet, ATM25, USB, IEEE -1394 or home phone -line network (HomePNA).  
  
MCMC  MTSFB TC T 010:2014  
5 4.2 The Premises Distribution Network (PDN) defines the technology for connecting subscribers’ 
equipment (e.g. PCs) with the ADSL transceivers (ATU -R). This P DN may be provided as an Ethernet 
interface, ATM25, USB, IEEE -1394 or a HomePNA backbone. The selection depends mainly on 
subscribers’ mix of services and network or service providers’ preference in the ATU -R interfaces.
