Intelligent Network (IN)

–           No charging for calling user

–           Charging of calling user as per local call

–           Charging of calling user at higher rates

No charging for calling user : FPH, VCC and VPN services fall under this category. Level ‘160’ is free at present and is proposed to be allotted to such services. Local exchanges need to analyse only ‘160’ and route the call to SSP. This level has to be created as charge free. New services of this type can be introduced in future without any requirement of further modification in local exchanges

Charging of calling user as per local call : UN (local) falls under this category. Level ‘190’ is free at present and is proposed to be allotted to such services. Local exchanges need to analyse only ‘190’ and route the call to SSP. This level has to be created as local charge. New services of this type can be introduced in future without any requirement of further modification in local exchanges.

Charging of calling user at higher rates : PRM and UN (long distance) falls under this category. Since the charging is at higher rate it is proposed that prefix ‘0’ may be used to have barring facility. Level ‘090’ may be used for such purpose. Local exchange will analyse ‘090’ and route the call to SSP. This level has to be created as ‘charge on junction pulses’. New services of this type can be introduced in future without any requirement of further modification in local exchanges.
