10.9 PBX Configuration—[2-9] System—System Options—Option 3— Confirmation Tone—Tone 1 : Calledby Voice13.1 PBX Configuration—[5-1] Optional Device—DoorphoneOperating Manual References1.3.22 Doorphone Call5.1.16 DSP Resource AdvisorDescriptionWeb Maintenance Console provides a tool for calculating the number of resources required for a given set ofoperating conditions. The Web Maintenance Console user provides information such as the number of portsfor a given resource (e.g., 16 extension ports using the G.729 codec) and the expected usage load (e.g., 50%busy), and the resource advisor calculates the number of DSP resources required to meet those conditions.This tool can be used in offline mode to simulate various PBX configurations and usage cases to help determinethe number and size of DSP cards required.This tool will also recommend which and how many resources to reserve for various features (® 5.1.17 DSPResource Reservation). The recommended settings can be applied immediately from the resource advisortool.The resource usage can be calculated using the following types of services and features:Service/Feature DSP Resources per UnitCO line using G.729 codec 2.2CO line using G.711 codec 1Non-IP CO line (ISDN CO line, analog CO line, etc.) 1Extension using G.729 codec 2.2Extension using G.711 codec 1IP-CS extension using G.729 codec 2.2IP-CS extension using G.711 codec 1Unified Messaging*1 1.3Two-way recording*1*2 2.3OGM*1 2Conference CO line*1 0.5*1 The DSP costs of the extensions/CO lines involved in the operation are not included in the per-unit DSP resource count.*2 Two-way recording also requires a conference CO line. For an example of the required DSP resources, see 5.1.18 DSP ResourceUsage.Example 1: Small OfficeIn a small office (e.g., 32 employees), the necessary number of CO lines and extensions is likely to be relativelysmall. In addition, the expected load on the system will also be small.(For clarity, unused services are not included in the table.)Document Version 2016-03 Feature Manual 1155.1.16 DSP Resource Advisor
