Abstract :
A recent survey of the telegraph and telephone facilities of Mexico showed that equipment was old, in poor condition, and insufficient. An over-all improvement program calls for rewiring overloaded principal lines, installation of up-to-date central office equipment, replacement of transmitters and receivers for radiotelegraphy, and other modernization steps.
