Emergency talkback call station series telephones are intended for use in public areas where direct assistance or hands-free communication is required, they provide a two-way link to assistance through GSM or VoIP, full duplex telephone transmission. a call may be initiated from the telephone or from the monitoring station. they have a rain cover, can block a part of the rain attack, more suitable for outdoor use.

What is VSAT? In China, very small aperture terminal (VSAT) communication service refers to the transmission of voice, data, multimedia communication, and other services between the center station and the VSAT terminal users (earth stations) within the country, and between VSAT terminal users, by using a satellite transponder and managed and controlled by the VSAT communication system center station. Overview of VSAT VSAT stands for "Very Small Aperture Terminal" and is also known as a "Satellite Communication Earth Station". It is a satcom communication system developed in the mid-1980s. VSAT is widely used in news, weather, civil aviation, civil defence, banking, oil, seismic and military sectors, as well as in remote areas. A typical VSAT network can accommodate 200-500 stations and has various applications such as broadcast, point-to-point, interactive and collection.

cnjb02@jinbinmachine. com Compared with single layer roof panel roll forming machine, double layer roll forming machine is designed to produce two different kinds of metal sheets which can be one trapezoidal roofing and one roof/wall cladding sheet; or one trapezoidal roofing sheet and one corrugated roofing sheet; or one trapezoidal sheet and one metal roof tile; or one corrugated sheet and one metal glazed roof tile etc. Double layer roll forming machine consists of uncoiler and its base, infeed guides, fixed position driven forming stations, shearing devices, hydraulic station, pld control console and so on.

They are IP-based Integrated PA & Intercom telephone, which are fully contained in an waterproof, impact resistant, anti corrosion housing with robust handset that provides complete protection against harsh environment, resulting in high reliability of the product long MTBF.

Features of the VSAT System 1. The user small stations in the VSAT system do not have high requirements on environmental conditions, and the communication is not affected by natural conditions such as geographical conditions, climate, earthquakes, floods, etc., and the communication quality and reliability are high. In the satellite coverage area, it has nothing to do with the geographical location of the ground station, and the cost of data transmission has nothing to do with the communication distance. In the case of long communication distance and large range, VSAT network is generally 20% to 50% cheaper than other communication means, and the more remote small stations the system has, the lower the unit cost and the better the scale benefit;
