19 Inch 16E1 TDM over Ethernet (IP) Converter

View : 576
Type : E1 over IP
Description :

TDMoIP-16E1 is mainly used to transmit voice signal on the IP network. It has 16 ports E1, 2 UTP Ethernet ports, and a fiber Ethernet port.


TDMoIP-16E1 is mainly used to transmit E1 signal on the IP network. It has 16 ports E1, 2 UTP Ethernet ports, and a fiber Ethernet port. It can connect the TDM device and the user’s low-cost wireless or lineate Ethernet/IP configuration, without affecting the voice quantity. Assures connecting to the physical E1 interface of any device seamlessly, such as PBX, mobile base station, SS7 signaling device, and voice mail system. It can be used in a communication system based on E1, such as LAN, WAN, MAN, and wireless network.


Providing emulation E1 channel through Ethernet, the difficulty is rebuilding timing information of the E1 code stream effectively at the exit of the network. The special disadvantages of Ethernet itself, such as random packet delay, without effective timing, transmit mechanism, transmission error, or collision that brings on packet loss, must be conquered. Our company resolves the difficulties above faultlessly by availing ourselves of technical advantages and adapting advanced clock disposal technology. TDMoIP-16E1 encapsulates the date of the E1 code stream to the packet and transmits it to the remote device through Ethernet.
