Since 1984, the Telecommunications Distribution Methods Manual (TDMM) is the definitive reference manual for telecommunications and information communications technology infrastructure design. Written by industry experts serving within a vast array of industries, as well as the telecommunications infrastructure supply chain, the TDMM, 13th edition, provides critical design information and practice for today's and tomorrow's networks.
