30pots voice fiber mux with ring network
Product Overview
The ring network voice fiber mux supports upstream/downstream optical port and optical fiber transmission, and supports various fiber network topologies: point-to-point, star, chain, ring network redundancy, and on this basis, the network is a more complex network topology, self-healing ring protection.
Center-side 30 FXO interface phones, each node device 1-2 FXS telephone interface, loop up to 30 telephones, to achieve stability, reliability and real-time data transmission in harsh environments. Its working principle is to form a ring structure on the physical connection, and the network signal forms a chain structure during operation. Once a node somewhere in the transmission cable is disconnected, the device automatically switches to the standby line for transmission in a very short time. Redundant ring structure not only reduces the risk of transmission of a data signal, a simplified installation, reduced the cost of the project.
high availability and reliability ,work flexibly, as well as the rich security features , makes it ideal for secure data transmission.
We have many types PCM multiplexer , support customization, best solution for you!
Features
l The host is designed to be 30FXO connecting with PBX , and a loop on the host device can reach up to 30 nodes (only one FXS for each node device );
l The device of each node can be 1-4 FXS fiber mux, if the device is 2fxs fiber mux, then the quantity of node will be max 15.;
l Voice access, support for caller ID function / reverse polarity billing / fax function;
l Supports various fiber network structures: point-to-point, star, chain, ring network redundancy, and can be combined into a more complex network topology. When the fiber is disconnected, the system will reestablish the normal communication network link and security system within 10 ms. After the self-healing protection is implemented and the network fault is removed, the bus signal transmission system will automatically recover
l Support multi-mode and single-mode fiber, multi-mode 0-2km, single-mode 0-120km, support circle network.
l A variety of power supply options: AC220V, DC-48V/DC24V, etc.; support AC + DC; AC + AC; DC + DC
