The Unitrans ZXMP S320 is an STM-1/4 compact SDH equipment launched out by ZTE CORPORATION. Apart from TDM, the system can effectively implement ATM and Ethernet services. The data services can share bandwidth via ATM VP ring and the Ethernet, and usage of the bandwidth has been improved. This equipment adopts a modular and compact design. T1 mapping path is employed, and compatible with both European and North American mapping path standards. The ZXMP S320 can provide 4 STM-1 and 2 STM-4 simultaneously, thus allowing to flexibly implement various networking applications.  Key boards backup is supported, hence the reliability of equipment in access layer can be guaranteed. Because different installation and power supply modes are supported, the ZXMP S320 can meet any requirements. Shortly, the ZXMP S320 features powerful functions, networking flexibility, easy installation and low cost. The system is designed for users´ satisfaction in STM-1/4 level with safe and effective low-end transmission.
