The facility of knowing your caller’s telephone number before answering the call, which has been available to cellular phone users only in India so far, has now been extended to the normal telephone users also in Delhi, Mumbai and some other cities of India through MTNL and DoT since 1st January. MTNL/DoT telephone exchanges transmit the telephone number of calling party just before the first ring while in systems used in USA and China, the data relating to the calling number is sent between first and the second rings. The number of calling party in India is transmitted by MTNL/DoT exchanges in DTMF codes. Two documents containing standards and specifications issued by DoT’s Telecommunications Engineering Centre (TEC) in the form of ‘Generic requirements’ and ‘Interface requirements’ for ‘Subscriber service unit for calling line identification presentation (SSU for CLIP)’ are available from TEC, Khursheed Lal Bhawan, Janpath,
