This Specification defines the minimum technical requirements for ultra-wideband (UWB) devices intended for use in confined areas of buildings or localised on-site operations.

UWB devices are meant for short range radio-communication, which involves the intentional generation and transmission of radio frequency energy that may spread over a very large frequency range and overlap with frequency bands allocated to radio-communication services.

A wide variety of new short-range devices (SRD) may employ the UWB technology. This includes the use of UWB SRD in communications, measurement, location, imaging, surveillance and medical systems. UWB devices will be integrated in portable and mobile equipment.

This Reference Specification identifies the optical interface requirements for the following types of equipment:

• Access network equipment which deploys a Passive Optical Network (PON) technology according to the ITU-T Rec. G.983/G.984 series or the IEEE Std 802.3-2005 (Part B of this Specification: Optical Access Network);
  
  
• Intra-office or inter-office network equipment which supports the Synchronous Digital Hierarchy (SDH) technology using optical interfaces according to the ITU-T Rec. G.957 and G.691 (Part C of this Specification: Synchronous Digital Hierarchy Equipment).
  
  
• Ethernet transport network equipment and service nodes such as IP-Routers and Automatically Switched Optical Network (ASON), using any optical interface specified in the ITU-T Rec. G.691, providing access link to equipment terminated at the customer edge (Part D of this Specification: Ethernet Transport Network).

This Reference Specification outlines the technical framework which is relevant for developing the Next Generation Networks (NGN). It has been established based on the high level NGN standardisation achieved in the ITU-T. It refers to the architecture for NGN given in the ITU-T recommendation for Functional Requirements and Architecture of the NGN for Release 1 (ITU-T Rec. Y.2012).

This Reference Specification defines the possible ways of evolving PSTN/ISDN to NGN. It is also established based on the high level NGN standardisation achieved in the ITU-T. Evolution of networks to NGN is dependent on operators' choices and needs. Network operators will choose an evolution path depending on their actual resources, business plans and strategies. They may choose different technologies and timeframes.

1. This Reference Specification (IDA RS VDSL) outlines the requirements for transceivers to use Very-high-speed Digital Subscriber Line (VDSL) technology to provide high bit rate digital transmission on metallic, unshielded wire pairs. It is derived from the ITU-T Recommendation G.993.1 (06/2004). VDSL is an access technology that exploits the existing infrastructure of copper wires and extends the copper-wire spectrum to 12 MHz. In comparison, the spectrum for the Plain Old Telephone Services (POTS) is limited to 4 kHz while the spectrum for the ADSL/HDSL is 1 MHz. G.993.1 VDSL can be deployed from Central Offices or from fibre-fed cabinets located near the customer premises.
   
2. The Reference Specification reflects a VDSL standard that is using Frequency Division Duplexing (FDD), frequency band plans (Plan 997 and 998), Upstream Power Back-Off (UPBO) method and Multi-carrier Modulation (DMT technology) in the Physical Medium Dependent (PMD) layer. As an indication to the industry that the preferred line coding for VDSL is DMT, implementation specific to the QAM technology will not be recommended for adoption (Annex I/G.993.1). ITU-T has agreed that the subsequent VDSL standard development shall be based on DMT and the VDSL2 Recommendation will specify only DMT modulation.

1. This Reference Specification (IDA RS PHLINE NW) describes a high-speed networking (LAN) technology, which allows several PCs connected to the same in-premise telephone lines to share a single Internet connection. The Specification defines the minimum technical requirements for connection of phoneline networking transceivers (PNT) for data transmission over the in-premises telephone wiring.
   
2. The Specification defines the system reference model for PNT; the Power Spectral Density (PSD) mask; and the basic electrical characteristics (ITU-T Rec. G.989.1). The Specification further outlines the characteristics of the isolation function (IF) for separating the in-premises wiring from the access network (ITU-T Rec. G.989.3).
   
3. Spectrum compatibility with radio amateur services, the Specification also requires PNT to have built-in notches for reducing RFI egress in the radio amateur frequency bands.

1. This Reference Specification (IDA RS CM3) defines the requirements for connecting 2nd generation Cable Modems (CM) to the Radio Frequency Interface (RFI) of high-speed data-over-cable systems. It is based on the newly approved ITU-T Recommendation J.122.
   
2. CMs deployed locally are still of the 1st generation, complying with the DOCSIS 1.1 CM standards. This Specification is prepared in anticipation of future introduction of the 2nd generation CMs, following the DOCSIS 2.0 CM standards.
   
3. The Reference Specification is an ITU-T version of the DOCSIS 2.0. It employs advanced TDMA and synchronous CDMA techniques, and offers symmetrical services with 3 to 6 times more upstream capacity than the DOCSIS 1.1/1.0 (30.72 Mbps compared with 10.24 Mbps / 5.12 Mbps). At the same time it ensures backward compatibility and increased robustness against interference.

1. This Reference Specification (IDA RS SHDSL) describes the internationally standardised SHDSL technology based on ITU-T Recommendation G.991.2.
   
2. The Reference Specification defines a technology for transmitting 2.312 Mbps on 1 pair of copper wire and 4.624 Mbps on 2 pairs. SHDSL provides an economic way for deploying E1/T1 service over 1 pair of copper wire using TC-PAM line coding to extend the reach to 4 km without repeaters. Applications include the carriage of multi-line voice over DSL, Inverse Multiplexing over ATM (IMA) as an alternative to FTTB, high-speed access for web hosting, VPN services and remote LAN.

1. Control of interference to radio-communications users
2. Control of interference to neighbouring PLC users
3. Electrical safety to users

1. To facilitate seamless Internet Protocol (IP) network and circuit switched network (CSN) interconnection anywhere in the network and the use of Voice over IP (VoIP) terminal equipment, IDA has published the following two reference documents:
   
   
   • Reference Specification for Internet Protocol and Circuit Switched Networks Interconnection
   • Guide for the Global Information Infrastructure Standards
     
2. These documents are based on the International Telecommunication Union's framework (http://www.itu.int) for the convergence of telecommunications network and IP network technologies, and recent standards for the Global Information Infrastructure (GII).
   
3. Today, the deployment of IP telephony is largely seen in the provision of international telephony in the form of cheap IDD calls. In the office environment, IP telephony has also begun to proliferate in PABX systems whereas IP integration in the domestic telephone network is just beginning. The "IP and Circuit Switched Networks Interconnection" provides references in support of the IP network and CSN convergence. Guidelines are provided for IP telephony standardisation, quality of service targets, and use of numbering and addressing resources.
   
4. Working on a broader level, the GII Guide provides a global information infrastructure framework for implementing the convergences of telecommunications, information and broadcasting technologies. It provides guidelines for technical interconnection at the various classes of reference connection points. It also illustrates interconnection between public network operators, between service providers and public network operators, between private corporate networks and public networks, and between end-users and networks.
   
5. Unlike the Reference Interconnection Offer (RIO), the IP Specification and GII Guide are not mandatory and are intended for voluntary use in the connection of IP networks and CSN by operators. IDA will review these two reference specifications from time to time to incorporate the latest developments in standards and technologies.
