The special highway communication network in Jilin Province is composed of communication system over the two highways from Changchun to Siping and Changchun to Jilin, which is divided into several manage layers such as communication center, sub communication center and communication station including truck communication system, transmission system and communication system. The truck communication system adopts optical fiber as the main transmission means and electric cable as the auxiliary. Both the optical fiber and the electric cable are placed in the pre laid tubes in the isolated part under the central line of the highway. Two kinds of tubes——plastic corrugated tube with four holes and silicon tube are there used separately for the highways of Changchun/Siping and Changchun/Jilin. To meet the requirement of highway communication, the transmission system is equipped with PDH photoelectric equipment including the auto conversed 1B1H code, and all the communication center, sub communication center and communication station are equipped with relay points and PCM for optical transmission. Communication system comprises business phone, emergency phone and mobile phone. Six sets of MD110 exchange board are provided for the business phone system, specially for the internal business communication and telecommunication between the management divisions along the highway. Emergency phones from different manufacturers are located in both sides of the road, totally 108 extensions are there in the network. 800 MHz alveolate automobile communication equipment is chosen for the automobile communication system to meet the demand of construction, patrol duty, rescue and maintenance.
