73Networking Configuration GuideChapter 4Application Resources overviewApplication Resources is a management tool for allocating system resources such as signallingchannels, VDI channels, media channels, and DSP resources. While the BCM manages resourcesfor different services by making resources available as they are needed, you can manage theresources by setting minimums and maximums for each service.For information on configuring application resources, see “Application Resources panel” onpage 77.Types of resourcesThere are four types of resources managed by the Application Resources panel:• Signalling channels• VDI channels• Media channels• DSP resourcesDifferent applications require different resources. For example, each media gateway requires oneDSP Resource and one media channel, but does not require any signalling channels or VDIchannels. Use the Application Resources Reservations table to see what resources are required byeach application. Whenever an entry contains N/A, the application does not use that resource.Total and Reserved ResourcesThe total and reserved resource options display the current levels of total and reserved resources.The total resource table displays the total resources on the system, while the reserved resourcetable displays what resources are currently allocated or in use.The total number of resources for signalling channels, VDI channels, and media channels exceedsthe maximum capacity for the BCM, you do not need to manage the resources based on thesechannels. For example, IP Trunks are the only application that use VDI channels, and even if theBCM maximum of 12 IP trunks are in use, they will not exceed the total of 62 VDI channels.There is no need to modify the IP trunks minimum and maximum, since the necessary VDIresources will always be available.The only resource you need to manage is DSP, which is used by media gateways, voice mail andCall Centre, Fax, and Conferencing.
