Murli, Is the cable twisted pair? Is it with or without loop current?
Almost any communications handbook with a chapter on transmission theory and/or wire and cable installation practices has information on bandwidth, impedance, envelope delay, noise,echo, termination etc ... will have the wire information you need. e.g. Hamsher: "Communication System Engineering Handbook", Bennet and Davey: "Data Transmission" Regards, Duane J.
