For the past 15 years the world of telecommunications has been facing a new type of challenge. The infrastructure and technologies originally designed to carry only telephony services have needed to evolve to cope with the expanding world of multimedia and data services.

New multi-service networks have had to be built on top of the legacy equipment of the PSTN, and it has been essential for this transition to be both smooth and cost effective. This transformation is referred to as the migration to Next Generation Networks, or NGNs.

Carriers’ prospects for future growthWith the transformation of traditional telephone PSTN services the carrier must focus on:

- providing new, cost-effective services for a reinvented revenue stream,

- preserving the existing services and regulative features with a new technology,

- avoiding any degradation of the services or inconvenience to the end-user,

- the possibility of functional scalability and capacity growth for newly deployed infrastructure.

All these issues are an encouragement for a fixed-line voice-service provider to evolve existing voice nodes and other network elements.

Solving the control-plane challengeSI3000 MSCN:

The changes have to be seamless and gradual with no inconvenience to end-users in order to guarantee future benefits for the service provider.

The right time and the right technologyIn an ideal situation the end-users would have the same user experience with the IP-based network as they had with the PSTN, although they will start to use new applications and services. Achieving such a situation is a challenging task, especially in suburban and rural areas where investments are very carefully chosen.

The prediction of a telco’s future revenue structure suggests that telephony is losing importance as a stand-alone service and is becoming part of a broader communications service. Revenue tends to increase where the telcos are able to offer a full bundle of services - in addition to telephony this includes messaging and video communications. The deployment of new services is mandatory.

During the process of network transformation it is crucial the users receive the same services and the same user experience together with the possibility of new services and expiriences.

Highlights of the SI3000 MSCN: it enables a wide range of telephony and multimedia

features for residential and business customers; it fills the gap between the existing PSTNs and IP-based

network architectures; it is a cost-optimized upgrade option for existing an

TDM infrastructure and the replacement of network elements;

the opportunity to reinvent revenue sources and to strengthen its competitive advantages.

SI3000 MSCN: a solution that promises a lotWith the SI3000 MSCN Iskratel addresses a broad segment of voice-based telcos’ transformations. Transformations are provided in terms of telcos’ different strategies, goals and capabilities, including the technology and market reality, standardization and regulative points of view.

The SI3000 MSCN, a member of the SI3000 Control Plane family, represents a compact solution for call control, service provisioning and mediation between IP-based and PSTN networks.

The SI3000 MSCN uses an open architecture and integrates multiple functional blocks within a single and compact control-plane product. Each functional block is usable as standalone component to provide interworking with third-party network elements.

The functionalities of all the network elements are enhanced by open, standardized interfaces that enable them to fully integrate with the SI3000 MSAN access nodes. The product is supported by an integrated element and a network-wide management system, the SI3000 MNS.

The SI3000 MSCN services

The economics, threat and success of VoIP services have encouraged many service providers to accelerate their deployment. These VoIP services attracted users with their low prices for basic features.

The answer to these challenges is to provide a serv-ice bundle like a multimedia VoIP service with rich features and a simple, easy-to-learn interface to use them.

Residential customers are already attracted to VoIP serv-ices by competitively priced IP telephony bundles that include a variety of services, such as internet access, local telephony access, unlimited calling, voicemail, call wait-ing, and caller ID. With the increasing competition, serv-ice providers need to retain customers, and prevent their switch to internet-phone-service competitors.

To reinvent a telco’s revenue stream firstly a cost-efficient platform has to be established. It demands an integrated, scalable, open-standard-based solution like the SI3000 MSCN. Additional CAPEX (Capital Expenses) reduction is achieved with the ease of administration, the ensured reli-ability and the efficient management of all the compo-nents.

Key BenefitsIncreased revenue opportunities – The SI3000 MSCN product offers a rapid and cost-effective expansion into new geographic markets and thus increases the carrier’s ROI (Return on Investment). The product delivers voice services to less demanding users and increases revenues with enhanced applications.

Feature-richness – The SI3000 MSCN provides customers a wide range of telephony features, from basic dial tone to advanced integrated services to improve productivity, such as the Si3000 Web Communicator with integrated unified messaging, the softphone, voicemail, presence, event notification, and the self-provisioning interface. Customers, using a single provider, benefit from simplified support and billing, which means they switch providers less often.

The social aspect of web-services usage will grow and this might boost traditional earning models, like talking on the phone and sending SMS messages. The behavior of customers is changing: the sharing of various content, such as pictures and video blogs, with friends and other people in the internet community has become increasingly common.

The SI3000 MSCN provides the carrier with seamless interoperability, whether offering services in a mixed TDM–NGN environment or whether fully migrating from a TDM to an NGN solution.

13

Services portfolioA rich set of SI3000 CS services combines services well known to residential subscribers

with business services available in a hosted PBX solution. Services are grouped in service families that relate to the call scenarios they are supporting.

Basic voice servicesThe SI3000 CS supports basic voice services supported by analogue and packet-based terminals on SIP, MGCP and H.248. These services include:

Basic call control for:- Local calls,- Domestic and international calls, - Outgoing or incoming calls from mobile subscribers,- Maintenance calls,- Special service calls, emergency calls, call waiting,- Direct calls to PBX extensions,- Outgoing calls from PBX extensions.

Supplementary services, Routing, Charging services, Protocol processing, Media gateway control.

Abbreviated-dialing servicesIn addition to all the abbreviated dialing options offered by the terminal equipment (direct keys, directories and lists, etc.) lists of abbreviated numbers for speed dialing can also be created on the SI3000 CS.

Call-completion services During an active call the user receives an incoming-call indication:

- the call-completion network service offers the caller the possibility to set a call-back request as soon as the called subscriber is available again.

- the standard call-hold service enables switching between active calls.

- distinctive ringing and music-on-hold for user-friendliness of communications.

BENEFITS OF LAYERED ARCHITECTURE: Revenue-driven network evolution Smooth deployment of new services Multi-vendor interoperability (IMS) Future proof

Number-identification services- call identification is used to increase accessibility

in the case of an unanswered call, call control or distribution.

- name-identification presentation for user-friendly calling-line identification.

- also represents the basis for malicious-call identification.

14

Call-offering services- Call forwarding – offers remote activation as a follow-me service, or on a spur-of-the- moment decision as a call-deflection service.

- Group call – the selected groups can distribute incoming calls in a sequential or linear mode or by ringing the whole group.

- Call transfer – the call-transfer services are executed as a blind transfer during the ringing or as the termination of a consultation call.

- Call-interception scenarios – for different reasons (e.g., non-existent numbers, moved numbers, user not present) incoming calls are terminated by the interception of a call or call-pick-up services.

Multiparty services- Conference services - enabling voice

connections between several users - the most frequently used is a three- party conference.

- The meet-me conference - resembles a chat room, where people can chat online for a certain period of time. The users can join the conference by dialing a special conference number.

Charging services- call-charging information is promptly delivered to subscribers on all port types.

Integrated applications offer billing or cost supervision for an individual subscriber or a group of subscribers for a specified time period.

- to prepaid users, the services are only available until the amount paid on the prepaid account has been used up (even during a call).

Call-offering services, Multiparty services, Inter-carrier connectivity, Charging services, Call-barring services, Alarm and notification call services, Teleworking services, Hosted PBX service

Call-barring servicesServices for placing or receiving calls in compliance with various criteria. The basic outgoing-call barring is based on the dialed

number. Some user groups are permitted to place calls to, e.g., local, city, inter-city, international or special numbers.

Alarm and notification call services- simple alarm calls are used as reminders with different frequencies: as single, daily periodic (with repetition number) or on chosen days of the week.

- complex notification calls enable a more efficient response in the case of an emergency. They are used as wake-up calls, high-priority calls, alarm calls in the case of a catastrophe, etc.

Hosted PBX serviceHosted PBX is a private-network service offered by a public service provider. Iskratel

Hosted PBX services bring headquarters, branch offices, remote sites and telecommuters together into a single dial plan.

Hosted PBX subscribers connected to different SI3000 MSCNs are included in a wide business group. Business groups can extend over a wide geographical area (this is known as wide-area Centrex) and their members have all the advantages offered to hosted PBX subscribers – private numbering, transparency of services on the network, and group internal charging.

Teleworking servicesA logically logged user can be authorized to access services from any phone at any remote location – regardless of the type of connection,

including POTS, mobile, etc.

Inter-carrier connectivity- traffic distribution is the routing

of traffic among several carriers based on the incoming traffic volume. It enables the equalization of incoming and outgoing voice traffic between carriers.

- least-cost routing is adopted inside a SI3000 CS and provides a cost-efficient trade and exchange of voice traffic between telecom operators. It is based on temporary inter-carrier price information provided from external systems.

15

Regulatory servicesLawful Interception – The Iskratel’s SI3000 products support ETSI-LI/SORM requirements to make it easy to apply the lawful intercep-tion of voice and other telecommunications

services by local or distant network subscribers that are processed in call servers monitored by the ETSI-LI/SORM system.

Number Portability – based on ITU-T standards and includes several different types of service:

- service-provider portability – provides end-users with the possibility of keeping their existing telephone (E.164) number when moving to an alternative service provider.

- location portability – provides the end-user with the existing E.164 number when moving to another geo-graphic location within the existing service-provider network.

- service portability – provides the end-user with the possibility of keeping their existing E.164 number when changing the type of telecommunications service (e.g., POTS into ISDN, GSM or IP).

Carrier pre-selection – Different carriers pro-vide different types of services, for instance, lo-cal, national, international or value-added spe-cialized services. To allow the subscribers of one

carrier to reach the services of other carriers, new types of routing are implemented in the SI3000 MSCN solution:

- static routing is based on an agreement between the subscriber and the local carrier about how subscribers’ originating calls will be routed (e.g., via which national or international operator) by the carrier.

- dynamic routing allows subscribers to select one of many alternative operators for each outgoing call sepa-rately with a dialing carrier access code (CAC).

- the combination of both principles is also available.

The SI3000 Signaling and Media Gateway

The SI3000 Signaling and Media Gateway (SMG) brings highly scalable and flexible PSTN-to-IP transport and signaling functionality to a VoIP network.

SI3000 SMG- Media Gateway- Signaling Gateway- Media Server

This powerful combination provides a cost-effective solution for carriers, system integrators and application developers seeking to develop carrier-ready, scalable, IP-based enhanced services that can be accessed from both PSTNs and IP networks.

It includes three main voice functionalities: the media gateway, the signaling gateway and the media server.

21

SI3000 SMG key features

Media Gateway

The media-gateway functionality ensures that the PSTN channel content is converted into a stream of data pack-ets by using various VoIP codecs (e.g., G.711, G723.1, G.726, G729 and Clear Channel) and vice versa.

Additional roles in the network:- Transcoding, compression and announcements,- Automatic fax and modem signal detection,- Echo cancellations (according to ITU-T G.168

recommendations), - Voice detection and silence suppression, - Comfort-noise generation (CNG), - Conference calling, - Tone detection/generation over TD (E1) and packet

(Gigabit Ethernet) interfaces,- Quality of Service (QoS) built-in mechanisms (replacing

lost VoIP packets (PLC), jitter buffer, elimination of vari-able delays, etc.) for toll-quality voice services.

Benefits viable means to “squeeze” additional IP revenues from the

legacy network; eliminates the need for a separate media server or

application server for simple applications; easy and cost-effective extension of IP-based services to

legacy users; integrated signaling and media-gateway functionality with

a media server on a single carrier-grade platform.

Media Server

The Media Server (MS) bundles the offer for the carrier with the following services: - it connects subscribers to a conference call, regardless of

the network type (IP and TDM),- it enables DTMF detection and generation,- it provides voice announcements, interactive voice re-

sponses, speech recognition and voice messaging with the interpretation of VoiceXML scenarios (also in combi-nation with Automated Speech Recognition (ASR) and Text to Speech (TTS) conversion servers).

The media server performs the indicated functionalities independently of the mode of coding for the voice signal in a call.

Signaling gateway

The signaling gateway provides the transformation of legacy TDM signaling (SSN7, DSS1 and V5.2) into IP-based session-control protocols (M2UA, M3UA, M2PA, IUA and V5UA) for communication with the call server.

This eliminates the need for the operator to adopt the complex SSN7 signaling on the TDM side.

In particular, the CAS signaling conversion to the IP net-work brings the carrier all the existing, well known capa-bilities.

Expandable system capacities the flexible SI3000 MNS software offers the possibility

for the carrier to choose between cost-effective HW platforms (e.g., installed on a notebook to manage a small network) and a distributed installation in a multi-blade-server hardware architecture.

geographical redundancy is assured by using the cluster operation for a fault-tolerant management and monitoring solution.

Central management database the operator has access to all the management

functionalities without the need to know where the actual subscribers and other resources are physically located.

mass provisioning enables the operator to apply actions on multiple network elements.

The SI3000 AS for rapid service deployment

The SI3000 AS is a flexible application platform that allows the deployment of value-added services as well as acting as a gateway for

third-party servers accessing the Call Server and Signal-ing Media Gateway features.

The SI3000 AS interacts with the Call Server or Signal-ing Media Gateway through standard interfaces, such as VoiceXML, CSTA (Computer Supported Telephone Ap-plication) or INAP (Intelligent Network Application Pro-tocol). Clients, external systems or third-party servers in-teract with the SI3000 AS through standard IT interfaces, including advanced technologies such as ParlayX.

The SI3000 CS for a new generation of SIP-based services and PSTN emulation

The SI3000 CS supports the following pro-tocols: SIP, SIP-T, SIGTRAN (M3UA, M2UA,

IUA and V5UA) MGCP and H.248. Standard support for SIP and SIP-T, enables connectivity for SIP-based applica-tions and ensures an IMS-ready environment.

NGN protocols are crucial for the undisturbed execution of legacy subscriber services in cases when the carrier upgrades the network using replacements of obsolete equipment or PSTN exchange enhancements with call servers.

The SI3000 SMG for media and signaling mediation between the IP network and the PSTN network

The SI3000 SMG is a master on the network borders. This highly scalable product with a unique combination of technologies for media and signaling processing pro-vides a signaling transfer point, a media server and gate-way functions.

The signaling transfer point provides connectivity for a wide range of existing installations on SSN7, ISDN, CAS and V5.2. It is controlled by the call server. In the role of a media server it provides the VoiceXML interpretation function and services such as tone generation, tone recognition, announcements and conferences for both types of networks, IP and TDM.

The SI3000 MSCN includes three essential components:

SCALABILITY MEANS A PAY-AS-YOU-GROW

SOLUTION FOR OPTIMIZED OPEX

Tune your performance and keep it robustThe SI3000 MSCN allows the gradual replacement of the existing network element in a “pay-as-you-grow” manner. It helps the carrier to achieve maximum protection of the investment.

The gradual growth in the number of subscribers results in the need to permanently expand the processing power. By distributing the traffic (trunks, subscribers) to several SI3000 CSs, the processing power of the whole solution increases significantly. Thus, it is possible to serve more traffic (subscribers/trunks). The centrally managed SI3000 MSCN allows seamless capacity expansion from a single server to a multi-server configuration.

Due to the multi-server architecture, the high availability of voice and other services is guaranteed in cases of potential disasters at the central call-control side.

MEA MEA is the ETSI standardized platform. The MEA

platform is Iskratel’s cost-effective hardware-de-ployment option, designed for metro, suburban and rural networks. It is also suitable for installation at large enterprises.

The blade concept of the SI3000 MSCN compo-nents allows the scalability of the NGN solution. It can be easily reconfigured from a compact ar-chitecture to a distributed architecture for larger configurations.

HARDWARE PLATFORMS

The AdvancedTCA (ATCA) hardware platform is designed to fulfill the requirements of next-gener-ation carrier-grade communications equipment. The SI3000 MSCN components, except for the SMG, run on an ATCA-compliant computer. SMG servers are inserted into the MEA platform at the high-end central-office or at any other location.

The ATCA-based SI3000 MSCN is convenient for high-end central-office locations and for service provision in densely populated urban areas. A single ATCA housing ensures the cost-effective installation of additional server blades in a single frame.

The road to the future

The existing infrastructure meets the new technology No two carriers are likely to follow identical paths in establishing a pure IMS architecture. However, with the SI3000 MSCN, each carrier has the possi-bility to adopt a telecommunications infrastruc-ture meet its current needs and its planned de-velopment strategy.

Iskratel’s approach to network evolution is based on the gradual migration of the existing PSTN in-frastructure towards the IMS-oriented architecture. The migration scenario is suitable for existing telcos and for competitive newcomers, deploying fully IP-enabled networks. Iskratel’s most important future role is to control and manage telecommunications and new web-based services from the fixed and mobile worlds through a single user profile at a single point.

Seamless migration towards IMS with the SI3000 MSCNThe migration towards IMS requires network-el-ement adoption in the service delivery, core and access parts of the network.

The Evolution - The goal of the process is to achieve the adoption of the newly offered services by the end-users regardless of the installed access technology.

Packet-based (SIP) subscribers inherently use these services, but existing POTS and ISDN subscribers are insufficiently covered. The AGCF functionality pro-vided by the SI3000 MSCN product line is the solu-tion for this issue. The AGCF functionality hides all the specifics of the existing PSTN towards the IMS core. All the existing PSTN subscribers, based on the subscription option, are seen as packet-based (SIP) subscribers from the IMS core, and they are able to consume additional packet-based services.

Network-element transformation – Regardless of the access part of the future IMS, the IMS core will evolve from the SI3000 MSCN product line. The

flexible SI3000 CS is transforming to be able to provide the func-tions of P/I/S-CSCF, BGCF, IWF, MRFC and MGCF/AGCF network entities. The SI3000 SMG provides the following IMS functions - SGF, T-MGF and MRFP. The SI3000 AS (unified communicator – IMS client) is evolving into a pure IMS-compliant SDP.

The desired goal – Finally, the “pure” IMS environment is going to give the carrier the opportunity to achieve its desired goals: a single environment for developing new services, to provide the subscriber with a single profile, managed by a single network element (HSS - Home Subscriber Server). The subscriber is go-ing to have a single, location agnostic identity, and will receive a single bill for the whole bundle of services.
