3 Resiliency, Redundancy and Reliability The software runs on highly reliable, fault-tolerant industry-standard servers under the Linux SLES 9 operating system. Clustering software protects against hardware and software failures, and controls failover of redundant Ethernet links and cluster nodes (redundancy is optional in the user range). By ensuring that all functions and applications maintain unrestricted availability, HiPath 8000 V3.0 provides a new level of quality in IP communications. The controls and supervises call setup; the actual voice traffic is carried over the LAN/WAN between endpoints. The administration/signaling and billing traffic is carried over a redundant pair of network interface cards through redundant, interconnected L2/L3 switches that provide redundant networking. The two servers, if collocated, also have (direct) crossover network connections. If geographically separated, the two servers are connected via redundant Layer 2 switches that provide a redundant L2 connection between the two nodes. The utilizes the Resilient Telco Platform (RTP) from Fujitsu Siemens Computers, a fault-tolerant, distributed computing platform that constitutes the underlying middleware for the system. The RTP provides services that allow applications to run with data resiliency and location transparency. In the event of a system failure, the RTP is designed to enable the HiPath 8000 to perform a system switchover while maintaining all active calls, with no loss of billing records. The can do this because it operates with redundant hardware nodes in active-active mode, as opposed to active-standby mode. There is also a Survival Authority which is external to the system (resides with HiPath 8000 Assistant V3.0). The Survival Authority must be installed in a different location than the two nodes. In the event of a total cluster failure, the Survival Authority instructs the node whether or not to take over. Solution Landscape The system is the ideal communication solution for large to very large enterprises. The communication architecture is designed for enterprises with distributed, remote sites, as well as for companies with campus-style structures. With, businesses of any size and across multiple locations can use all system features and applications universally. can also incorporate existing systems, such as HiPath 4000, in the overall solution, as well as third-party systems. Many new capabilities are added to the. They include new and enhanced features in the softswitch, new configurations, new endpoints, gateway and media server choices, as well as an expanded list of applications for customers to choose from. Features New subscriber, Business Group and user features and functions for V3.0 include the following: Business Group System Speed Calling Lists Different Forwarding Targets for Internal/External Calls Display/Alerting Enhancements for Call Pickup Displaying Call Forwarding Information at the Forwarded Station Executive Busy Override Extended Number of Direct Station Selection (DSS) Keys Multibyte support Payload Encryption System functions and features that are new in include the following: HiPath 4000 V3 survivable media gateway using Comdasys proxy Media server support for 12 additional country/language pairs Operator ENUM Permit multiple Modification Table entries SIP-Q between multiple systems Software Development Kits (SDK) Support for Assistant off-line database generation tool Support for redundant media servers Survival Authority for node separation Transport Layer Security (TLS) for SIP server interfaces Virus protection for software production also provides the following serviceability and administration features: Assistant as strategic administration tool HiPath RapidStat for gathering critical resource information Easy administration for branch office environments Easy IP address changing PAM.D vs. PAM.CONF (Pluggable Authentication Modules for Linux) Point-and-click patching Improved split-mode upgrades Management System management for may be implemented in two ways: Assistant Command Line Interface (CLI) Assistant For all user configurations, the Assistant is the strategic Web-based tool for administering the V3. For installations with fewer than 5000 users, the Assistant can be installed on the same server as the software and the integrated HiPath Media Server. In installations with more than 5000 users, it is necessary to install the Assistant, as well as the HiPath Media Server, on a separate, external server. Command Line Interface system provisioning and administration can be performed using a traditional command line interface (CLI). Features/functions which must be activated or provisioned only once are still managed using the CLI, e.g., tracing and other maintenance functions. The CLI is always accessible via a secure shell, and can be accessed via Assistant or directly from the maintenance port of the. Security supports Secure RTP (SRTP) but is dependent on SRTP support from the media devices that are used. SRTP secures voice communication by encrypting the RTP packets between media devices. introduces support for Transport Layer Security (TLS) on SIP and SIP-Q server-to-server connections, so TLS can now be used on both SIP endpoint and SIP server interfaces. Media Servers The offers the following media server options: RadiSys Convedia CMS-1000 (or CMS-3000) Media Server for up to 30,000 users/300 (360) ports Integrated HiPath Media Server for users/100 ports

4 RadiSys Convedia CMS-1000 & CMS-3000 The RadiSys Convedia CMS-1000 Media Server is an alternative option for HiPath 8000 systems with fewer than 15,000 users. The CMS-1000 delivers the media processing power required for a broad range of services such as multimedia conferencing, calling cards, interactive voice response (IVR), IP Centrex, call centers, unified messaging, network gaming, and speech portals. Media processing capabilities of the CMS include announcement generation, audio and video bridging, DTMF tone detection and generation, transcoding, message play/record, and speech processing. Because it is compatible with industry standard protocols, the CMS-1000 Media Server can be shared and controlled by multiple softswitches, call agents or application servers in any next generation VoIP network. While the CMS-1000 is a low-cost, entrylevel media server optimized for smaller systems, the Linux-based CMS model offers higher performance, increased capacity and improved security and management features, as well as dynamically maximized media processing capabilities. HiPath Media Server The HiPath Media Server is an integral part of systems for medium-size enterprises supporting subscribers. This software-only server solution plays tones and announcements in the language requested by the, or in a configurable default language. The HiPath Media Server supports redundancy as well as station controlled conferencing, and is administered by the HiPath 8000 Assistant V3.0. The Media Server can be installed on the same server as the system software, requiring no additional hardware, or on an external server (must be on the same server as HiPath 8000 Assistant). Media Gateways To access the public switched telephone network (PSTN), the solution provides the following gateway options: HiPath 4000 Survivable Media Gateway RG 8700 Survivable Media Gateway RG 2700 Survivable Media Gateway Third-party gateway products Survivable Media Gateways (SMG) In branch offices with a HiPath 4000 V3.0, survivability is made possible through the use of a Comdasys Convergence SIP proxy. This proxy takes the registrations from the phones and the HiPath 4000 gateway and passes them to the via the WAN. If the drops out or does not respond in a timely manner, the local SIP proxy takes over and tries to mediate the calls, including routing PSTN calls through the HiPath 4000 gateway. When connectivity to the is re-established, the proxy resumes forwarding the requests to the as usual. The RG 8700 provides a complete Siemens solution for, as well as basic survivability for branch offices in the event of network failure. Survivability, a standard feature of the RG 8700 gateway, is accomplished through the use of SIP phones that are dual-registered with the and the RG If the RG 8700 can no longer communicate with the, it switches to survivable mode, allowing the dual-registered SIP phones access to the PSTN trunks and, conversely, allowing incoming calls from the PSTN to be distributed directly to the SIP phones. The RG 8700 family of Survivable Media Gateways comprises 3 models that interwork with : RG 8716 with 16 T1/E1 spans, RG 8708 with 8 T1/E1 spans, and RG 8702 with 2 T1/E1 spans. No license is required. The RG 8700 V1.2R1 software adds SIP-Q functionality for connectivity to HiPath 4000 and third party products which support QSIG. The RG 2700 gateway, designed for organizations with a head office and small- to medium-size branch offices, is used for cross-site networking. This SMG provides a guaranteed connection from the central system to as many as 30 subscribers in branch offices, allowing them to use network-wide resources.this survivability solution does not require dual registration from the SIP phones. Small Branch Office (SBO) Gateways These gateways connect endpoints in a small office scenario. Gateways from Mediatrix, and optional survivability provided by Comdasys connect these locations to the. Customers can continue to use their previously installed third-party SIP gateways with the. The supported functionality depends on how these gateways adhere to the relevant SIP standards. Interoperability testing may be required to confirm feature behavior. The HiPath Ready Lab is available to vendors seeking to certify their products with the. SIP Endpoints The following Siemens SIP endpoints are supported: OpenStage 20/40/60/80 optipoint 410/420 S optipoint 150 S optipoint WL2S (wireless) opticlient 130 S Selected third-party phones may also be certified through the Siemens Ready Lab. OpenStage 20/40/60/80 OpenStage is Siemens' new generation of IP phones, providing a new level of ergonomics, performance and extended features. The OpenStage family includes 4 models (OpenStage 20, OpenStage 40, OpenStage 60, OpenStage 80). OpenStage 20 is the economy model and OpenStage 80 represents the high end model. The OpenStage IP workpoints are standards-based and SIP-compliant. OpenStage V1 supports key features in the feature set. optipoint Phone Family optipoint 410/420 S The feature that distinguishes the optipoint 410 S / 420 S family of phones, in particular, is the customized range of models. A choice of five different telephone models is available to suit all workstation requirements: optipoint 410 S / 420 S entry optipoint 410 S / 420 S economy optipoint 410 S / 420 S economy plus (with built-in LAN switch) optipoint 410 S / 420 S standard optipoint 410 S / 420 S advance In addition to supporting the V2.2 features of its predecessor SIP V6.0, SIP V7.0 also introduces support for Secure RTP (SRTP) and encryption of RTP streams (voice calls).

5 optipoint 150 S The optipoint 150 S phone is a cost-optimized device that completes the Siemens portfolio at the low end. optipoint WL2S (wireless) The SIP-compliant optipoint WL2 professional S wireless LAN handset addresses the growing SIP market and supports Siemens and third-party SIP-compliant systems. opticlient 130 S Softclient opticlient 130 S is a PC client that uses SIP for telephony on the real-time IP system. It combines the advantages of enhanced telephony with convergence of IP-based infrastructures. And, since it based on the SIP protocol, opticlient 130 S operates with other SIP-based systems, requiring minimal adjustment. HiPath Deployment Service Software distribution and configuration of phones are done using a Deployment Service (DLS) tool. The DLS facilitates Plug and Play for phones and provides a HiPath Management application for administering workpoints. The HiPath Deployment Service allows administrators to remotely configure phones en masse, such as when a set of new devices is deployed for the first time. However, the tool can be used at any other time as a means of configuring a group of phones with a consistent set of data. Analog Adapters Analog adapters from Mediatrix allow users with existing analog phones, analog fax machines and modems to connect to the SIP environment, thereby preserving their investments. Applications HiPath OpenScape HiPath OpenScape is a high-functionality collaboration application that fits into an enterprise s existing voice and data infrastructure, tying together phones, voice mail, , text messaging, directories, calendaring, instant messaging and conferencing services. HiPath OpenScape s tight integration into the environment allows users to take advantage of market-leading collaboration and mobility features, and provides the ability to leverage advanced user and group presence features. HiPath Xpressions HiPath Xpressions combines voice, fax, and text (Short Message - SMS) services on a Windows 2003 platform and transforms them into a Unified Messaging system for use in the. Built using a modular, scalable client/server architecture, HiPath Xpressions can be configured to meet users individual communication needs. New functionality in HiPath Xpressions V5.0 supports voice and MWI over SIP. HiPath ComAssistant HiPath ComAssistant is a Web-based call control and communication filtering application that enables users to manage incoming voice and communications from their desktop. HiPath ComAssistant offers computer telephony integration (CTI) features such as click & dial, call logging, LDAP address book search, and One Number Service (ONS). With a choice of two easy-to-use graphical user interfaces (GUI), HiPath ComAssistant provides home and business users with rules-based communication filters and routing capabilities to optimize accessibility and increase efficiency. HiPath MetaManagement The HiPath MetaManagement Suite provides a comprehensive and all-embracing management solution for the standardized administration of all HiPath platforms and applications. HiPath Accounting Management (HiPath AM) is the accounting application for processing and analyzing call data for incoming and outgoing voice and VoIP calls over different network operators (carriers) as well as internal connections in HiPath standalone systems and networks. HiPath Fault Management (HiPath FM) supports and simplifies network management by graphically displaying the complete communications network, showing the status of each element. Special plug-ins optimize the detection, diagnosis and removal of failures. HiPath FM also monitors hardware and software from other manufacturers, interfacing via SNMP (using the manufacturer-specific enterprise MIB). HiPath User Management provides a simplified umbrella solution for the creation, deletion and modification of user data and communication resources across all HiPath platforms and applications in a HiPath network. All relevant user data are stored in a Directory Service and are available for all HiPath applications with an LDAP interface. HiPath Quality of Service (QoS) Management provides comprehensive, easy to use functions for configuring, monitoring and analyzing all HiPath VoIP components in a HiPath network with respect to the relevant QoS parameters. HiPath ProCenter HiPath ProCenter is the Siemens contact center application for the HiPath switching platforms. Consolidating the features of its predecessors, HiPath ProCenter V7R1 provides an enhanced, intuitive agent interface and visual management tools introduced with HiPath ProCenter Agile. HiPath ProCenter s connectivity with the HiPath 8000 makes it possible to implement a single contact center solution for all HiPath platforms. HiPath ProCenter also offers an attendant console desktop that has the same functionality as the agent desktop, plus some attendant-specific features. Because the desktop integrates on top of optipoint 410/ 420 and opticlient 130 devices, attendants can be located anywhere the IP network extends. This allows for maximum flexibility in centralized as well as decentralized attendant environments. Genesys Suite The supports Genesys via SIP. The Genesys SIP Server provides complete functionality of the Genesys Suite for agents connected to SIP devices. Agents are registered to the so they are fully integrated into the enterprise.

6 Server Technical Data The software runs on highly reliable, fault-tolerant industry-standard servers, providing carrier-grade reliability. The hardware configuration includes an IBM System x3650 T server, or two servers for fully redundant operation. For installations with users, redundancy is optional, so the second server is not required. The operating system is SUSE Linux Enterprise Server 9 (SLES 9); a SolidTech database is running on each server. Each server has two (2) 3.2 GHz Intel Xeon processors, up to 16 GB of DDR2 memory, two (2) L2/L3 Ethernet switches and eight (8) 10/100/1000 base-t Ethernet links, set up as pairs connected to the Ethernet switches (two external L2/L3 Ethernet switches are required for a redundant configuration.) The x3650 T is equipped with dual, redundant hot-swap DC or AC power supplies for high availability, up to six PCI slots for extreme expandability, and an external alarm panel providing 24/7 surveillance of system outages.
