● A subscriber spends 10 % of his working time in the call state.
● The average time per call is 3 minutes.
● The availability loss is limited to 1.2 %.
A higher number of gateway channels (HG 1500-Linecard) must be taken into account in con-
texts with a higher volume of calls (e.g. call centers).
In a pure IP network, the number of gateway channels must be greater or equal to the number
of TDM trunks.
The required number of HG 1500 boards for VoIP is the sum of the total number of gateway
channels, MOH channels and conference channels.
