Equipped with up to seventy- two 10/100 Ethernet ports and six GBIC uplink modules for flexible LAN applications. Imbedded Stateful Inspection firewall options allow for robust OmniAccess 6000 security solutions.

  • Page 9: Server Elements (Dhcp, Tftp, Management)

    Alcatel-Lucent openly recognizes the challenges faced by customers with existing 802.11 network implementations. For this reason, Alcatel-Lucent also seeks to support Mobile IP Touch - Voice over Wireless Local Area Network solutions on a variety of approved third-party infrastructure architectures.

  • Page 10: Tftp Server

    After the radio network is operational, the goal of RF Spectrum Management changes to that of tuning and adjusting radio parameters in order to maintain a high degree of performance. With Alcatel- Lucent, RF Spectrum Management is largely automatic, requiring little configuration or intervention from the administrator.

    Voice over WLAN Mobile IP Touch Design Guide R2.0 1.1.6. NOE features Since OmniPCX Enterprise Rel 7.1 the MIPT set has integrated NOE feature (Dial by Name, Notification for Messaging, etc.) and as a result can be globally considered as an IP Touch set, but limited by its ergonomics.

  • Page 16: Operational Modes And Considerations

    Being as no two customer network environments are exactly the same, it is critical for technology such as VoWLAN to possess a great degree of flexibility. Alcatel-Lucent’s MIPT solution is not exempt from this requirement. The following section highlights some MIPT architectural adaptabilities.

  • Page 17: Appliance/Overlay Mode

    In Appliance Mode operation, Access Points are not directly attached to Alcatel-Lucent OmniAccess Wireless Switches. In this type of operational mode, the Alcatel-Lucent OmniAccess Wireless Switch acts only as an Access Point Controller and does not directly host AP via local 10/100 ports.
  • Page 18 Much like the above discussed Inline Power Injector, Inline Power Patch Panels can be used to achieve the same effect when more than a few devices require IEEE 802.3af power. Alcatel-Lucent offers Power Patch Panels in 6, 12, and 24 port varieties.

    MIPT handset. No infrastructure facility (such as IEEE 802.11e) is presently included in Alcatel-Lucent’s MIPT VoWLAN R2.0 solution to provide for QoS from the MIPT handset towards the wired LAN. For prioritization from the MIPT handset in the wireless environment towards the wired LAN, only proprietary methods and adaptations of the IEEE 802.11 PIFS (PCF Interframe Spacing) option are...

  • Page 20: Security

    Security is always a sensitive topic to discuss, and opinions on how best to provide for it vary greatly from one engineer to the next. With this in mind, Alcatel-Lucent is constantly developing the list of security options available within the MIPT VoWLAN solution offer to satisfy as many different opinions as possible.

  • Page 21: Mac Address Filtering

    2.3.3. MAC Address Filtering MAC address filtering facilities are provided for within Alcatel-Lucent’s OmniAccess product platforms. Alcatel-Lucent strongly encourages the use of Local MAC address filter rules to help ensure that only authorized wireless clients are permitted to join the VoWLAN network.

  • Page 22: Design Process For Vowlan

    3. Design Process for VoWLAN 3.1. Pre Sale Data Collection In order to prepare an Alcatel-Lucent VoWLAN solution, several pieces of documentation must be sourced from the customer. The accuracy of a final system proposal is directly related, in most cases, to the amount and quality of information collected prior to initiating design formulation.

  • Page 23: Logical Diagram

    Voice over WLAN Mobile IP Touch Design Guide R2.0 3.1.2. Logical Diagram Logical Diagrams are also critical for complete and accurate solution construction. The logical diagram must include information related to the existing customer VLAN strategy, QoS policies, Security measures, redundancy and fault tolerance schemes, as well as future provisioning and traffic shaping. Information gathered from the logical diagrams will determine IP addressing schemes, security measures, and VLAN mapping as well as influence certain physical design options (ideal SVP Server location, ideal TFTP &...

    Voice over WLAN Mobile IP Touch Design Guide R2.0 3.1.3. Floor Level Maps/Diagrams To complete detailed planning, a floor level diagram is required. This floor level diagram can be used in the design process in two different ways, Prediction Planning and for the Site Survey. This diagram does not necessarily need to include detail on how desks are situated within office and where toilets and potted plants are located within restroom, but walls, dividers, elevators, pillars, windows, doors, and other obstacles should be clearly marked and to scale.

  • Page 25: Customer Specific Application & Design Considerations

    Voice over WLAN Mobile IP Touch Design Guide R2.0 3.2. Customer Specific Application & Design Considerations Due to the fact that Alcatel-Lucent’s MIPT VoWLAN solution is being offered in a multi-stage fashion with evolving capabilities, it is important for the design engineer to compare expected customer usage patterns against current MIPT release restrictions before proposing an Alcatel-Lucent MIPT VoWLAN solution.

  • Page 35: Converged Wireless Environments (Voice & Data Combinations)

    Voice over WLAN Mobile IP Touch Design Guide R2.0 3.7.1. Converged Wireless Environments (Voice & Data Combinations) One of the most significant reasons that businesses look to use wireless LAN technology to support voice is the desire to have a single infrastructure for both voice and data services. While this may at first sound like a very simple thing to implement, it often is far more complex to design than most customers originally anticipate.

    10-13 non- overlapping channels (depending on local market restrictions) it makes available. Customers seeking this type of solution can unify the infrastructure elements by using Alcatel-Lucent’s OmniAccess product suite for both Wi-Fi formats. Alcatel-Lucent’s OmniAccess 70 Access Point can be effectively leveraged to construct networks for both 2.4 GHz (802.11b/g) and 5 GHz (802.11a) networks...

  • Page 37: Predictive Environment Solution Options (Responding To Rfx)

    Voice over WLAN Mobile IP Touch Design Guide R2.0 3.8. Predictive Environment Solution Options (Responding to RFx) When answering an RFP or RFI, normally, there is little possibility of scheduling a Site Survey for various reasons: Building under construction or not yet built, short delay to answer the RFP, fair competition clause, etc.

  • Page 38: Predictive Tool Coverage Planning

    802.11 data clients with typical power and sensitivity specifications. It is for this reason that the use of predictive planning tools is not currently recommended by Alcatel-Lucent. Even in the case of Alcatel-Lucent's predictive planning tool, the unique operational characteristics of MIPT handsets can not be taken into full consideration, resulting in often flawed and under-engineered proposals.

  • Page 39: Environment Verification & Validation

    Audit is mandatory for all solutions prior to installation. Alcatel-Lucent’s OmniAccess platform family can be used to support data as well as voice. For solutions that propose both voice and data coverage, it is important to distinguish between the needs of the voice and data elements.

  • Page 40: Post Install Survey

    As a general rule, Alcatel-Lucent recommends re-evaluation whenever new technology demand is generated or roughly every 18 months. Some customers may be able to happily use VoWLAN technology in a static environment for many years without a renewed survey, others may find that continuous evolution of network demands require a validation every six months.

  • Page 43: Quotes & Orders

    Unfortunately, the quotation process for the MIPT VoWLAN R2.0 solution is not fully automated within ACTIS as many of Alcatel-Lucent’s other voice technologies. For this reason, engineers are strongly encouraged to complete the framework of the target VoWLAN design prior to beginning the ACTIS process.
