IPC will register the U.S. missions telegraphic address with the host government authorities so that the mission can commercially send and receive telegrams.

(Uniform State/USAID)

a. The Departments telegraphic processors convert outgoing telegram formats into modified ACP-127 transmission format. ACP-127 format conforms to National Communications System (NCS) standards and ensures intercommunications between U.S. Government telecommunication facilities. The ACP-127 format is composed of 16 format lines containing separate components. Each line must be in the specific order indicated in 5 FAH-2 H-320. You do not need all the format lines for all messages.

b. If you deviate from the ACP-127 format, the Departments telegraphic terminals and relay equipment will reject the telegram. You must understand the purpose of each format line and its components so that you can correct errors during processing. See 5 FAH-2 Exhibit H-314 for an example of a typical formatted telegram.
