Telecommunication Equipment Production Industry

What is Telegraph Workshop

At the time Independence all the telecommunication production facilities were left behind in India. The signal workshop of North Western Railway 🚂 at Lahore could not caster for requirements of Pakistan Post & Telegraph Department. A workshop was established at Kotri near Hyderabad in 1948 to produce line materials and telegraph apperntus. The production of this workshop was also ships to the Eastern Wing from Karachi. This workshop had a big galvanizing plant. The workshop still exist but with reduced range of production. A similar workshop was also established at Dhaka ( now Bangladesh ) in 1956- 1957.

The Telegraph invention

The invention of the telegraph is credited to Samuel Morse, who developed the electromagnetic telegraph system in the 1830s. This invention revolutionized long-distance communication by transmitting coded messages over wires using electric signals. It played a significant role in the expansion of businesses, news dissemination, and even military operations.

Telephone ☎️ Industry Of Pakistan

An agreement was signed in 1952 with M/s Siemens of Germany for established Telephone Industry of Pakistan ( T I P ) at Haripur. The production of telephone equipment was commenced in 1955.
