Introduction:
M155TA Series integrated service network system device is a new generation high-density integrated access device with bandwidth sharing performance, researched and developed based on adopting logical design. It can transmit 1~3 channels Ethernet and 2 channels serial port signals via two pairs of standard E1 path or optical fiber, to flexibly satisfy user’s different service application requirements. The system network topology structure can form ring network, chain network, ring + chain, ring + ring and ring mixed network.
Main Feature:
Can adopt ring or chain network, networking form is flexible
Adopt fast packet switching mode and independent core patent technology to achieve bandwidth recourse full usefulness.
The device has its own IP address, provide multi-task polling centralized GUI based on TCP/IP WEB GUI or UDP port.
Excellent network management system
Service transmission all support E1 connector bidirectional protection, to make sure the service quality
E1 loop-back and isolation: when master and slave E1 path occur loop-back, it can automatically identify and isolate it to avoid broadcast suppression caused by ring network
Node master, slave E1 path power failure direct connection performance: node automatically isolate, E1 path overpass is conducted
Provide 2 channels 10M/100M sharing self-adaptation Ethernet interface
Provide 2 channels serial port, with physical connection auto-checking, data transparent transmission performance.
Desktop device with compact size, easy to install.
+24VDC, -48VDC or 220 VAC power supply is optional, adapt to multi power supply environment.
