Product Description
Cab Integrated Radio
GSM-R is an integrated special digital mobile communication system wholly developed for railway communication. Based on the GSM infrastructure, it provides ASCI including intensified multi-priority eMLPP, VGCS and VBS and also provides scheduling operation specialized for railway including function addressing, function number representation, access matrix and addressing based on location. Based on this informatization platform, the users of railway department can develop every application systems of railway. Fig 1-3 is the structure chart of operation model of GSM-R system. So the operation model of GSM-R system can be generalized as follows:
GSM-R Operation = GSM Operation + ASCI + Railway Application
GSM-R cab integrated communication equipment is applied to railway GSM-R system and is fixed on the cab used by engine driver. The equipment replaces the former wireless train scheduling communication system and provides voice and data transmission channel between cab and station.
All of the exterior size, installation size, installation requirements, type and pin of every plug-in of cab integrated communication equipment satisfy the requirements of < GSM-R motorcycle Main technical conditions of integrated communications equipment (provisional).

Tianjin 712 Communication & Broadcasting Co., Ltd. Established in 1936, is one of the earliest large-scale comprehensive electronic leading enterprises in China. As the first-class national enterprise, TCB is the Pioneer of the railway train deployment radio station of China and the Homeland of China VHF radio station.
As the key unit under the company, the mobile communication Dept. Is mainly engaged in the research, design, production and sale of the equipment for the civil special-purpose communication system, Trunked Mobile Communication System, Train wireless dispatch communication system. As the birthplace of the first railway radio station it has already been regarded as the fixed manufacture unit of the communication equipment for railway by the Ministry of Railways.
We took the lead in providing the first set of multi-based ESAS trunked systems in 1995. Up to now, we have already designed and provided more than 100 sets of Trunked Mobile Communication System, which are with more than 800 channels in Beijing, Tianjin, Chongqing, Liaoning, Heilongjiang, Shandong, Shanxi, Hebei, Henan, Anhui, Sichuan, Yunnan, Guizhou, Qinghai and Hainan and other places. We will try our best to open up the broader market of sale at home and abroad based on the superior products and perfect services. The digital trunked system mobile phone that our factory researches and develops independently, and has intact independent intellectual property. This mobile phones which are manufactured localized and have extremely high products cost performance, are the only independent digital trunk system mobile phones out of home solution, and are satisfied digital trunk system standard of China.
Rich research and design resource, consummate production technology, advanced production equipment, make the company in the invincible position in the market competition all the time. We insist on the enterprise aim of " your satisfaction, our eternal commitment and pursuing ". We will try our best to offer the first-class service, create the first-class products, and cast the open and wide and brilliant one for tomorrow together!
