PCM in Radar Communication System Applications

The PCM equipment system is currently the most commonly used integrated access communication equipment in domestic enterprises. It utilizes the standard E1 data transmission channel, adopts the PCM format, and directly provides various user interfaces such as voice, data, and image. However, changes in radar systems and the development of radar communication networks have made the original radar communication equipment unable to meet transmission requirements or the development of radar networks. Through research and development, adopting the PCM equipment system in radar communication systems can expand interface types and add network management functions, making it a good approach.

The PCM equipment has numerous advantages, which is why it has become one of the most commonly used communication transmission access devices in enterprises today, and it is widely applied in important industries such as radar communication systems. Below, Raytrans will discuss [PCM equipment](

I. Flexible Networking and Large Capacity

1. It can form point-to-point, star, chain, ring, and other network topologies, and can be used in conjunction with various transmission devices such as ATM and SDH, offering flexible networking methods and strong network adaptability.
2. Service access capacity: Each centralized PCM multiplexer system can access up to 420 services at a rate of 64kbit/s.
3. Trunk link capacity: Each centralized PCM multiplexer system can transmit services with a capacity of up to 14 E1 (14*30*64kbit/s).
4. Cross-connect capacity: External cross-connect equipment can be added to achieve full cross-connection of 14 E1 lines and 420 timeslots.
   II. Convenient Configuration
   It adopts a branch board structure, with 14 independent branch boards for plugging in various voice, data, and other service modules. Different types and quantities of modules can be mixed or selectively inserted, making service configuration and expansion extremely convenient.
   III. Rich Access Types
   It provides various integrated service access including ordinary telephone (subscriber loop), hotline telephone, 2/4-wire E&M interface, 2/4-wire audio interface, asynchronous data interface (RS232 and V.24, etc.), synchronous data interface, N*64K Ethernet interface, and more.
   IV. Network Management Functions
   Users can input some simple commands through the management interface to quickly and effectively test and set parameters of the device. These commands can be used for any type of handover, querying system status, and performing simple diagnostics. Most importantly, the network management software enables intelligent configuration and management of all network devices in complex service networking.
