(a) The number of points in a circuit shall be determined in the following manner:
(i) in the case of a circuit between two points or places, the starting point or place of the circuit and the end point or place of the circuit will invariably constitute two points;
(ii) any intermediate point or place in the circuit will also constitute a point provided that the benefit of the leased circuit is also available at that intermediate point;
(b) the supply of services shall be treated as made in each of the respective States or Union territories, in proportion to the number of points lying in the State or Union territory.
Illustration 1: A company T installs a leased circuit between the Delhi and Mumbai offices of a company C. The starting point of this circuit is in Delhi and the end point of the circuit is in Mumbai. Hence one point of this circuit is in Delhi and another in Maharashtra. The place of supply of this service is in the Union territory of Delhi and the State of Maharashtra. The service shall be deemed to have been provided in the ratio of 1:1 in the Union territory of Delhi and the State of Maharashtra, respectively.
Illustration 2: A company T installs a leased circuit between the Chennai, Bengaluru and Mysuru offices of a company C. The starting point of this circuit is in Chennai and the end point of the circuit is in Mysuru. The circuit also connects Bengaluru. Hence one point of this circuit is in Tamil Nadu and two points in Karnataka. The place of supply of this service is in the States of Tamil Nadu and Karnataka. The service shall be deemed to have been provided in the ratio of 1:2 in the States of Tamil Nadu and Karnataka, respectively.
Illustration 3: A company T installs a leased circuit between the Kolkata, Patna and Guwahati offices of a company C. There are 3 points in this circuit in Kolkata, Patna and Guwahati. One point each of this circuit is, therefore, in West Bengal, Bihar and Assam. The place of supply of this service is in the States of West Bengal, Bihar and Assam. The service shall be deemed to have been provided in the ratio of 1:1:1 in the States of West Bengal, Bihar and Assam, respectively.
