entipo-ias-w-2.qxd 21/3/2001 12:17 ìì Page 2 INTRACOM's Access Network System (IAS) is a family of products specially developed for the provision of integrated Full Service Access Platforms including voice, data, narrowband & broadband services. IAS products are characterized by modular architecture providing flexible, fast and cost effective adaptation to present customer needs, in addition to upgradability and expandability supporting future service requirements. IAS-F, INTRACOM Fiber Access Network System, is applicable for areas where the primary access network is predominantly wireline, INTRACOM while Wireless IAS-W, Access Network System, is applicable for areas where access is primarily wireless as prescribed by the geographical morphology and residential spread. Both systems utilize common subscriber access modules and are mutually managed by powerful network management system ensuring the highest level of integration and flexibility for the total network environment. entipo-ias-w-2.qxd 21/3/2001 12:18 ìì Page 3 System Overview Wireless based technologies have nowadays become a strong rival to the wirelinebased counterparts, for building modern access networks. The advantages of wireless access systems include scalable investment profile, short roll-out time and increased flexibility. IAS-W is a digital wireless access system providing operators with state-of-the-art solutions for creating telecommunications access networks, while bringing most advanced services to subscribers. The utilisation of IAS-W system offers a microwave primary network while the last-mile subscriber connections can be implemented either via copper cable or completely wireless. In the latter case, IAS-W acts as a WLL system through an integrated DECT subsystem. Applications IAS-W offers customised solutions to meet diverse operators’ needs : In urban and suburban areas: IAS-W can satisfy in a cost-conscious manner the stringent time and capacity requirements in areas where the rapid expansion of potential subscribers base requires urgent deployment of telecommunication servicing, including ISDN and high speed data, but the existing cable infrastructure is either not sufficient or not available. In rural areas: IAS-W is the optimum solution for such areas which are characterised by large distances from the Local Exchange, low subscriber density and grouping, harsh terrain and environmental conditions, lack of telecom and utilities infrastructure. In Data networks: IAS-W can be configured to support applications such as Business Networks, LAN interconnection, high-speed Internet Access or to act as a back-haul network for micro/pico cellular or WLL base stations. System Architecture An IAS-W Point-to-MultiPoint system includes one central node and up to 120 remote network nodes configured to serve any required network topology in a range of several hundreds of kilometres.

IAS-W can also be deployed in sectorised configuration, increasing total system capacity. Subscriber equipment is connected to IAS-W remote nodes via : Wireline network - The subscriber equipment is directly connected to the closest IAS-W node via last-mile wireline, or DECT air interface - The subscriber equipment is connected to the telephone socket of the DECT terminal installed in the customer premises. The terminal is linked by DECT air interface to the closest IAS-W node, which is equipped with appropriate DECT interface units and antenna system. System Components Wireless Central Node (WCN) WCN is the single connection point between an IAS-W system and the Telecommunications Network, provides the interfaces between the system and the Local Exchange and/or Data network as well as all the main required control and traffic handling functions. WCN also provides the relevant interface for IAS-W Network Management System. The Network interfaces supported are : ! Digital (ETSI V5.2 SL/ML) ! Analogue (2-wire) ! n x 2 Mbps (G.703) to Data networks IAS-W is transparent to the Local Exchange providing subscribers with all the revenue generating services. Terminal Node (TN) The Terminal Node (TN) is a remote network unit housed in a cabinet suitable for outdoor or indoor installation. It communicates with WCN or RN, via a TDM/TDMA radio unit and serves as the termination point for the wired subscribers within an IAS-W network. It is easilly configurable to accept all availlable interface types, and to accommodate various subscriber densities at each site. Compact Terminal Node (CTN) The Compact Terminal Node (CTN) unit is a version of Terminal Node used to serve either areas with lower subscriber densities or individual users with high traffic/service requirements enhancing thus further network design flexibility and cost effectiveness. It is intended for outdoor use and is equiped with an integrated antenna system. Repeater Node (RN) The Repeater Node (RN) is used to enhance system coverage, in the cases where no line-of-sight exists or very long hop distances are required. Cascaded RNs can Interfaces - Services extend system range to hundreds of kiloIn order to satisfy the diverse service meters. It operates as traffic-through or requirements, IAS-W is equipped with the following access interfaces: !

DECT Subsystem The DECT WLL subsystem incorporated within IAS-W provides an end-to-end fixed wireless connection, eliminating the need for drop wire in the local loop, in areas where drop wire is expensive or impossible to be installed. Each DECT Subsystem includes the following units : The Wireless Subscriber Card (WSC), integrated within a remote network node, performing the interfacing of the DECT-connected subscribers to the core IAS-W system. The Wireless Terminal Adaptors (WTA), i.e. the DECT terminals, installed at the subscribers' premises, available for indoor or outdoor installation. Network Management Management services are based on : ! Local Terminal graphical Windows-based application, running on a Personal Computer. It is connected to the WCN providing the whole system with full access. ! IAS-W Management System (ARMS), an Element Manager Application for monitoring and managing numerous IAS-W systems, providing standardised interfaces to Operations Support Systems (OSS). IAS-W Management System facilitates rapid installation & configuration of the network while provides extensive Alarm Hadling, Testing and Performance Analysis facilities. entipo-ias-w-2.qxd 21/3/2001 12:23 ìì Page 6 Radio in the Local Loop solution based on IAS-W In an IAS-W system all connected subscribers can be served through its incorporated DECT subsystem.
