  • Page 18: Introduction

    MiVoice Office 250 Engineering Guidelines INTRODUCTION The MiVoice Office 250 is a versatile system that can be scaled to address the needs of a wide variety of small and medium-size businesses. To achieve this flexibility, the MiVoice Office 250 offers two optional pieces of hardware, a Processor Expansion Card (PEC-1) and a Processing Server (PS-1), that may or may not be recommended based on the customer’s specific...

  • Page 19: When To Add A Processor Expansion Card

    Engineering Guidelines WHEN TO ADD A PROCESSOR EXPANSION CARD The MiVoice Office 250 Base Server has a built-in Processor Module that provides the system with a limited base number of digital signal processor (DSP) resources. It is important to note that DSP resources can be used for IP resources (e.g., VoIPs), as well as for other various...

  • Page 20: Oversubscription

    MiVoice Office 250 Engineering Guidelines For systems that are predominantly configured with digital telephones, a PEC-1 is not typically required. On the other hand, systems that contain a large number of IP phones, IP trunks, IP networking, or voice mail ports may require a PEC-1 to increase the pool of available DSP resources.

  • Page 21: Dsp Resource Costs And Limits

    IP device, this peer-to-peer audio does not decrease the number of DSP resources necessary for a call. This is because the MiVoice Office 250 allocates a DSP resource for each IP device on a call, as the call might require an audio path back to the PBX when performing certain features (e.g., the hold feature).

  • Page 22: System Calculator

    IVR MSR can be allocated on the main processor module only, not on a PEC-1.) Mitel recommends consulting the System Calculator if one of the following is true: • If the site has more than 50 devices that consume a resource with a lower cost.

  • Page 23: High Priority Vs. Shared

    If all of the phones attempted to place a call, then 60 phones would camp on waiting for a trunk to free up. Keep in mind that the MiVoice Office 250 does not actually reserve DSP resources for the high priority devices (except for File-Based MOH). The resource pool categories within the System Calculator exist only to determine the amount of resources the IP phones share among themselves and the remaining features.

  • Page 24: Phones To Devices Percentage

    MiVoice Office 250 Engineering Guidelines PHONES TO DEVICES PERCENTAGE The System Calculator displays the percentage of phones to various devices to give the administrator an idea of the amount of oversubscription that inherently exists in the system. In the following example, 25% of the phones at most can be on an outside call, 10% of the phones at most can place a call to voice mail, 8% of the phones and trunks can call voice mail, and 23% of the phones and voice mail ports at most can be on an outside call.
  • Page 25 Engineering Guidelines It is important to note that because the System Calculator does not take every factor into account, the system may still require a PEC-1 to provide enough DSP resources for certain features (e.g., paging, all-ring hunt groups, background music, advanced conferencing features, etc.).

  • Page 26: When To Add A Processing Server

    MiVoice Office 250 Engineering Guidelines WHEN TO ADD A PROCESSING SERVER The MiVoice Office 250 provides enough call control processing power to handle most typical-size systems with average call traffic. However, some installations may benefit from the additional processing power provided by a Processing Server (PS-1), formerly known as the CS-5600.

  • Page 27: Hunt Groups

    Engineering Guidelines HUNT GROUPS If a site has a large number of hunt groups used concurrently (e.g., in a call center environment), then the site should be equipped with a PS-1. The number of hunt groups, combined with medium to high call traffic that rings into a hunt group, greatly increases the need for a PS-1. ALL-RING HUNT GROUP MEMBERS If a site has all-ring hunt groups containing more than 30 members, then the site should be equipped with a PS-1.

  • Page 28: Voice Mail Ports

    32 with medium call traffic, Mitel recommends that the system be equipped with a PS-1. If a site has a combined voice mail port count of 24 or more with high call traffic, Mitel recommends that the system be equipped with a PS-1.

  • Page 29: Processing Server Guidelines

    Engineering Guidelines encoding for e-mail synchronization, Mitel recommends that the system be equipped with a PS-1 to reduce the delay in delivering the message via e-mail. PROCESSING SERVER GUIDELINES The following table defines the system limits that require a PS-1 based on the system configuration or characteristics combined with the system call traffic.

  • Page 30: Call Load (Calls Per Hour)

    Voice Mail Ports (medium/high) (32+/24+) combined UVM and NuPoint UM ports If the total number of phones and trunks exceeds 400, then Mitel recommends that the system be split into a multi-node system. The following table indicates the system limits that the administrator should follow when determining whether or not to configure a system with a PS-1.

  • Page 32: Oai Applications

    OAI application to be node aware so that it does not have to manage the connections to multiple nodes and manage multi-node scenarios. • CT Gateway offloads OAI processing from the MiVoice Office 250, thus allowing for more heavy applications to connect to a single system. OAI APPLICATIONS GUIDELINES The following table defines the recommended number of OAI applications based on the application type and call traffic.
  • Page 33 Table 6: OAI Applications Guidelines MAXIMUM NUMBER OF APPLICATIONS LOW CALL MEDIUM CALL HIGH CALL OAI APPLICATION TYPE TRAFFIC TRAFFIC TRAFFIC Light Applications (e.g., UC Express) Mitel recommends that no more than 30 heavy OAI applications connect to a system equipped with a PS-1.

  • Page 34: Uvm Coexisting With Nupoint Um

    The v3.0 software release added support for NuPoint UM. Since then Mitel has recommended that UVM and NuPoint UM not coexist on the same MiVoice Office 250. However, there is functionality that UVM can provide that is currently not offered on NuPoint UM, as well as functionality on NuPoint UM that currently is not offered on UVM.

  • Page 35: Determining The Correct Compact Flash-Type Card Size

    DETERMINING THE CORRECT COMPACT FLASH-TYPE CARD SIZE The MiVoice Office 250 contains a compact flash-type memory card that provides storage for the various system features and functionality. The size of the card is directly proportional to the capacity of UVM voice data; however, the UVM voice data competes with the following for memory card space: •...

  • Page 39: Codecs Compatibility Matrix

    Engineering Guidelines • The camera should be IEEE 802.3af PoE compliant, allowing the camera to receive its power over the LAN connection. • The camera must be ONVIF (Open Network Video Interface Forum) compliant. ONVIF defines a protocol for the exchange of information between different video devices. ONVIF compliance is intended to ensure interoperability between devices.

  • Page 40: Network Configuration And Bandwidth

    MiVoice Office 250 Engineering Guidelines Three different bandwidth settings can be independently applied to the uplink and downlink connections: • High – limits the bandwidth to 1.5 Mb/s • Medium – limits the bandwidth to 1.0 Mb/s • Low – limits the bandwidth to 512 kb/s NETWORK CONFIGURATION AND BANDWIDTH For more details please refer to MiVoice Conference/Video Phone Engineering Guidelines.

  • Page 41: Bandwidth Requirements For Mivoice Conference/Video Phone

    If a Network Group contains two devices that use different codecs, then these calls can result in no media. In this case, P2P media should not be configured. The figure below shows an example of the MiVoice Office 250 configured with an MBG to create successful video calls.

  • Page 45: Recommendations

    Engineering Guidelines RECOMMENDATIONS When using video on teleworker devices, start with the device in standard resolution. It is not as bandwidth intensive as HD/HD Widescreen. The phone deployed on premises must be the video conference leader. For best video quality your LAN must support VLAN tagging and QoS. Your service provider must provide a SLA which guaranties upload and download speeds large enough to account for burst.

  • Page 46: Mid-Call Features

  • Page 48: System Calculator

    PEC-1 and/or a PS-1 is recommended. The System Calculator may even determine that the system exceeds the recommended limits of all configurations of the MiVoice Office 250. In this case, the site may require a multi-node system to supply the required system configuration and functionality.
  • Page 49 (UWP) sessions that can occur concurrently. Based on the assumption that a UWP page can load, on average, in approximately 20 seconds, the Mitel 5000 supports up to 8 con- current UWP users, or a single administrator session with a background traffic load of up to 10 simultaneous calls.

  • Page 50: System Calculator Outputs

    In the following example, Mitel recommends the Mitel HX w/ PEC-1 system. The Mitel HX w/ PS-1 and Mitel HX w/ PEC-1 & PS-1 systems are also valid systems. The Mitel HX is not recommended.

  • Page 51: Phones To Devices Percentage

    Engineering Guidelines PHONES TO DEVICES PERCENTAGE The System Calculator displays the percentage of phones to various devices to give the administrator an idea of the amount of oversubscription that may exist in the system. In the following example, 33% of the phones at most can be on an outside call at the same time, 27% of the phones at most can place a call to voice mail, 20% of the phones and trunks can call voice mail, and 26% of the phones and voice mail ports can be on an outside call.

  • Page 52: Examples

    MiVoice Office 250 Engineering Guidelines EXAMPLES This section contains examples from the System Calculator to demonstrate how the results are displayed based for various configurations. DIGITAL HX This following sample configuration is a fully digital system with 20 conferencing ports and eight...

  • Page 53: Ip Phone Hx

    Engineering Guidelines In this example, the HX Controller platform is the perfect choice. The system does not require a PS-1 because the device count is low. The IP Phone/Shared chart indicates that features like Meet-Me Conferencing and voice mail can be used without any chance of resource issues because the chart indicates 100% for the HX Controller platform.

  • Page 54: Ip Trunks

    MiVoice Office 250 Engineering Guidelines The device count is not high enough to require a PS-1, and the non-PEC-1 allows 87% of the IP phones and conference ports to be in use at the same time. This value is more than the recommended 50%;...

  • Page 55: Ip Phones/Sip Trunks Hx W/ Pec-1

    Engineering Guidelines Because there are no IP phones, the percentage of IP Phone-to-Shared consist of only the conference ports. Keep in mind that SIP trunks and voice mail ports are not part of the IP Phone-to-Shared percentage, but they both use compression. If the system could use the Concurrent IC Calls setting of Low (i.e., 10%), then this configuration could be deployed without a PEC-1.

  • Page 56: Large Number Of Ip Phones, Trunks And Uvm Ports Hx W/ Pec-1

    MiVoice Office 250 Engineering Guidelines The percentage of Phones-to-Trunks indicates that 25% of the phones can be on an outside call at the same time. The HX’s IP Phones-to-Share percentage is only 20%; therefore, this option is not recommended. The HX w/ PEC-1 system indicates that 100% of the phones can be on a call at the same time;...

  • Page 57: Digital Hx W/ Ps-1

    This system is on the borderline of requiring a PS-1 based on the IP phone, trunk, and voice mail port count. If this system plans to grow or has high call load, then Mitel recommends the site be configured with a PS-1. DIGITAL HX W/ PS-1 This sample configuration does not have IP phones or SIP trunks.

  • Page 58: Digital And Ip Phones Hx W/ Ps-1

    The percentage of IP Phones-to-Shared is 100% for the HX Controller platform; therefore, the system does not require a PEC-1. However, because of the 200 digital telephones, Mitel recommends that the system be equipped with a PS-1. Note that the MiVoice Office 250 no longer requires a PEC-1 when adding a PS-1.

  • Page 59: Fully-Loaded Configuration

    Engineering Guidelines Because the recommended system is an HX PS-1, the UVM ports reside on the PS-1, thus eliminating the need for compression. This allows the IP Phones-to-Shared percentage of 53% to be over the recommended percentage of 40%. If this system requires a greater percentage concurrent IC calls, then an HX PEC-1/PS-1 is recommended.

  • Page 60: Exceeds All System Requirements

    PEC-1 and a PS-1. Because UVM resides on the PS-1, the percentage of IP Phones-to-Shared is slightly greater than the HX PEC-1 configuration. EXCEEDS ALL SYSTEM REQUIREMENTS In this example, the configuration consists of values that exceed the recommended limits of the MiVoice Office 250. In this case, Mitel recommends a multi-node configuration.
