JT-C(2000) type on-board system of cab signal can be applicable to 25Hz and 50Hz AC counting system; 1.9 mode and new standard (TB/B3060-2002) and other frequency shift modes of electrochemical section or non-electrochemical section; new standard (TB/T3060-2002) UM71 system; ZPW-2000 system signal; polar frequency and multiple on-board systems of cab signals.

The system passed technical review organized by Transportation Bureau of former Ministry of Railways in February 2008, obtained administrative license of National Railway Administration of the People's Republic of China in October 2014 and obtained CRCC certificate in August 2015.

JT-CZ2000-kj series on-board system equipment host of cab signal has the following characteristics: 1. Driving information of TAX2 box is combined with carrier frequency switch information preset in on-board equipment for automatic locking of carrier frequency and switch; it realizes automatic locking of carrier frequency and switch in the whole process without intervention of drivers. The method is unique in China; 2. Mature DSP technology, "two×two-out-of-two" fault -tolerant structure is adopted. A set of fault can be switched into another set for operation automatically; 3. DSP digital signal processing technology combining frequency domain processing and time domain processing is adopted, under-rate sampling, digital filtering, FFT and IFFT operation and other modern digital signal processing methods are adopted, which improves resolution ratio and operation rate of frequency spectrum; 4. The equipment has self-detection function; 5. Cab signal recording sheet is provided with recording function of accurate positioning. Operation state and ground track circuit state information of cab signal is recorded, train positioning output by TAX box of operating monitoring recorders and other information can be received at the same time; 6. Dual power supply of ultra-wide range with isolation, dynamic control lighting and conditional power supply is adopted to guarantee reliability and safety of system; 7. It has remote monitoring and diagnostic function.
