In view of Vinh to Nha Trang section communication transmission network designed for unified Vietnam Railway Line Vinh to Sai gon communication signal updating project, Vinh and Nha Trang both encounter equipment butting problems on account of SDH optical synchronous digital transmission equipment provided by different manufacturers. Butting scheme includes optical interface butting and electrical interface butting. Through investigation, study and repeated analysis and communication, consensus is reached to use 155 Mbit/s ( E) and 2 Mbit/s electric butting.
