The commu-nication system automatically detects that no DSP channels are required.ConferencesIn the case of conferences, the number of gateway channels seized corresponds to the numberof stations and IP workpoint clients involved.Channels required for gateway connectionsThe following table shows the number of gateway channels (HG 1500 boards) necessarybased on the existing IP workpoint clients.The calculation of the values is based on the following assumptions:● A station spends 10 % of its working time in call status.● The average time per call is three minutes.● The availability loss is limited to 1.2 %.Provisions should be made for more gateway channels (HG 1500 boards) in high traffic volumeenvironments (for example, call centers).
