Abstract:
A method of determining equipment requirements in a telephony system comprising the steps of:receiving a demand forecast and desired blocking values for a telephony system in a first geographic region; calculating a number of a first component in the system through use of the forecast and the desired blocking value; determining a tong term expected blocking for the system based on the traffic forecast wherein determining comprises the steps of: identifying numbers for at least one additional component in the system based on the number of the first component; identifying availability values for the first components and the additional components; calculating long term expected blocking by systematically calculating blocking values for the system based configurations of the system which take into account at least one failure scenario; comparing the long term expected blocking value to the desired blocking value, and if the long term expected blocking value is greater than the desired blocking value, increasing at least one of: the first component and the additional component in a systematic manner, performing the step of determining a lone term expected blocking again; and identifying an optimal configuration associated with the long term expected blocking value.
