INFORMATION

16E1 over Ethernet multiplexer is mainly used to transmit voice signal over IP network. It has 8*E1 interface, 2 UTP Ethernet port and 1*fiber Ethernet port. The 16E1 IP multiplexer can connect TDM device and user’s low cost wireless or lineate Ethernet/IP device, without affecting the voice quantity. It assures connecting to 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 the 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 E1 code stream effectively at the exit of network.16*E1 over Ethernet IP special disadvantages of Ethernet itself, such as random packet delay, without effective timing transmit mechanism, transmission error or collision that brings on packet lose, must be conquered. Our company resolves the difficulties above faultlessly through availing ourselves of technical advantage and adapting advanced clock disposal technology. The 16E1 TDMoIP equipement encapsulates the data of E1 stream to the packet and transmits it to the remote device through Ethernet.

The 16E1 over ethernet multiplexer can support point to point application (two 16E1 device work together) or point to multi-point application (the 16E1 multiplexer in the central site work with 1E1/2E1/4E1 TDM over IP in remote sites).
