    You require a no. of parameters like Average Holding Time , Traffic per subsriber etc for this calculation. Here is an example taking some assumptions You may do exact calculations as U will be knowing your parameters.
    Traffic for 1000 Subs with 0.1E* per subscriber is 100E
    BHCA= (100x 3600 sec )/60* Sec (Avg Holding Time of a cct)
    Now you need to calculate Traffic on Your DTMF resources from this BHCA
    Traffic on DTMF resources= (6000 x 6* Sec)/3600 Sec = 10 E

    DTMF circuits required for 10 E Traffic with required GOS from Erlang B Table is 20.

    No. of cards required = 20 / No. of DTMF generators per card

    * Assumptions made for example, You mayput your own figures.
