WebSphere Voice Response Version 6.1 System Requirements

Software	Hardware
Mandatory Software IBM AIX V6.1 (5765-G62) with minimum Technology Level 03 Service pack 01 IBM XL C Enterprise Edition for AIX, V9 (5724-S70) - the C RTE component included with the AIX installation media. IBM 32-bit SDK for AIX, Java Technology Edition, V6, Service Refresh 7 (SR7), level 6.0.0.175. This is available as a free download and must be installed prior to the installation of WebSphere Voice Response V6.1. IBM DB2 Workgroup Server Edition V9.5(1) (5765-F35) at minimum fix pack level 4. * * IBM DB2 Workgroup Server Edition (DB2 WSE) Version 9.5, program number 5765-F35, is shipped with WebSphere Voice Response V6.1 as a "limited use" copy, entitling customers to install and use DB2 WSE, subject to the terms and conditions of the license agreement that accompanies DB2 WSE. Note that DB2 WSE is not part of WebSphere Voice Response V6.1 and is subject to its own license agreement. DB2 WSE is also available as a separate product from IBM. Optional Software IBM XL C/C++ Enterprise Edition for AIX, V9 compiler (5724-S71) to compile Custom Servers. This is an additional, chargeable product. IBM WebSphere Application Server (5724-J08) IBM Communications Server for AIX, V6.3 for host communication using terminal emulation (5765-E51) JAWS screen reader on a PC for accessibility; for more information visit: http://www.freedomscientific.com/fs_products/software_jaws5intro.asp WebSphere Voice Server, V5.1 (VoiceXML only) customers requiring text-to-speech and voice recognition Single System Image (SSI) servers recommended to use JFS2. WebSphere MQSeries, V5.3 is only required if the customer wishes to use the XML provisioning capability provided by Unified Messaging for WebSphere Voice Response. A WebSphere MQSeries license must be purchased separately. J2EE 1.3-compliant Web application server software to host the Unified Messaging for WebSphere Voice Response interface and Voice interface, for example, WebSphere Application Server, V5.0. Local Number Portability (LNP) Server for SMDI. A sample LNP Server is provided.	IBM Power4, Power5 or Power6 processor-based Power Systems servers (those systems supported by AIX 6.1) or IBM BladeCenter POWER processor-based blade servers. For TDM telephony connectivity, one or more IBM DTTA adapters (FC 6312) are required in a supported IBM Power Systems server. VoIP SIP connectivity requires a Power Systems server or BladeCenter POWER processor-based blade server. No DTTA is required - the system Ethernet adapter is used. Optionally, a VoIP/TDM gateway is required to connect to legacy TDM infrastructure. WebSphere Voice Response V6.1 supports the DTTA adapter in all IBM POWER Systems in which the DTTA adapter has been previously supported. Refer to the WebSphere Voice Response adapter guidance at: http://www.ibm.com/support/docview.wss?rs=761&uid=swg21253839 In addition, for current POWER6 processor-based Power Systems servers: IBM Power 520 and Power 550 servers: maximum 2 x DTTA adapters in system unit PCI slots Power 520, Power 550, and Power 570 servers: maximum 4 x DTTA adapters in each of maximum 2 x LPARs, using 7311-D20 drawers for attachment of DTTA adapters to the systems. WebSphere Voice Response 6.1 does not support the DTXA adapter, withdrawn in June 2004. DTEA is still supported on the same system units as WebSphere Voice Response for AIX V4.2.3. For further information, refer to Software Announcement 206-009 (RFA #42558), dated January 17, 2006. Adapter compatibility: DTTA and DTEA can be mixed in system units in any combination up to a total of three or four adapters, respectively. Mixing of DTTA and DTEA in the same system unit allows applications to use double trunk where calls between VoIP and PSTN can be bridged; for example, in IP call centers. Note that a single DTEA can support 96 channels when configured for T1 (U.S./Japan) and 120 channels for E1 (rest of the world). Like DTTA, each DTEA adapter provides support for four telephony trunks. For installations where there is more than one DTTA or DTEA card in the same system unit, a top connector cable is required to connect all adapters that are used by WebSphere Voice Response V6.1 in the same system unit. This cable, known as the H.100 bus cable, is available in two lengths, one with four drops and another with eight drops. For all but the largest configurations that also use fax adapters, or if adapters are installed in adjacent slots, the four-drop cable will usually be suitable. This cable can be ordered using one of the following options: At the same time as the system unit is ordered with the appropriate feature number. For example, p5-520 - feature #2877 H.100, four-drop cable, or p5-550 - feature #4353 H.100, eight-drop cable. As an MES on an existing system unit using the same feature numbers. Directly from a telephony cable supplier.
VoIP/SIP considerations: Power Systems servers and BladeCenter POWER-based blade servers for use with VoIP and WebSphere Voice Response V6.1 require, for each WebSphere Voice Response V6.1 instance: A minimum of two processor cores A dedicated physical Ethernet interface (no DTTA adapter required) A base of 1 GB of RAM An additional 10 MB of RAM per channel Any system meeting the above requirement is suitable for VoIP. Moderate to large systems utilizing assistive technologies and Java or VXML applications may require additional RAM, and more or faster processors. Capacity planning for adapterless configurations has to account for the processing otherwise done by the DTTA adapter. A development system with fewer than 30 channels may be supported by a single processor. A POWER6 processor-based system with 2 x 4.2 GHz processors can easily support 480 channels of a simple state table application. Additional factors in SIP capacity planning are for the use of DTMF detection and voice compression, both of which may reduce call capacity. DTMF detection: The system unit's processors are used for DTMF detection. This cost can be avoided if the VoIP network supplies DTMF send/receive keys using RTP payload packets: RFC2833 (Telephone Event). Compression: WebSphere Voice Response can store voice data in its database using 5:1 compression. Voice is sent uncompressed (G711) over the VoIP network; therefore, the system unit's processors need to carry out the required compression and decompression on record and playback, respectively. For more information, contact your IBM representative. Adapterless configurations have the following double-trunking capabilities: Calls can be double-trunked between adapterless connections using the Trombone Custom Server. Adapterless connections can coexist with DTTA in the same system unit, allowing hybrid PSTN/VoIP configurations in, for example, IP Call Centers. However, calls cannot be double-trunked between adapter and adapterless connections. Coexistence with DTEA (hardware VoIP adapter) is not supported.	AIX LPAR support considerations: Although AIX Power systems in general can host many LPARs, any given system is limited to a maximum of two instances (LPARs) of WebSphere Voice Response. One or two additional 7133-D20 I/O drawers may be required to attach to a system in order to provide sufficient slots for WebSphere DTTA hardware adapters and any other adapters used by the system or LPARs. Where a WebSphere Voice Response instance uses more than one hardware DTTA adapter, all the adapters must be physically linked with a H.100 cable, and hence must reside in the same system or I/O drawer, ideally in adjacent slots. Where a system is hosting two WebSphere Voice Response LPARs, the adapters of each WebSphere Voice Response LPAR are separate, and require separate H.100 cables. Virtualization and Micro-partitioning in WebSphere Voice Response LPARs are not supported. This limitation means that each WebSphere Voice Response LPAR requires its own communications adapter (for example, Ethernet), disk adapter (for example, SCSI), and its own physical disks. It is strongly recommended that no other applications are run in the same LPAR (or system, if LPAR is not used) as WebSphere Voice Response. It is strongly recommended that any system or LPAR hosting WebSphere Voice Response should have at least 2 dedicated processors (cores), especially where production loads are envisaged. If the adapterless VoIP WebSphere Voice Response solution is used, or if a 7311-D20 drawer is attached, a minimum of two dedicated processors per LPAR is mandatory.
