Features Specifications:Sell E1 multiplexer MUX4E1-Tplus  MUX4E1-Tplus E1 multiplexer  With 4 E1 lines to transmit 2 Ethernets data, and the 2 Ethernet can work at the same time when they are in different LAN. For example, the IP of LAN1 is 192.10.10.1, the IP of LAN2 is 128.1.1.1 the two Ethernets 10/100Mbps can work at the same time by using MUX4E1-Tplus. The maximum permitted transmission delay among the 1st E1 to the 4th E1 is 16ms (on condition to keep the frame in order), which can permit the device running stably in every kind of completed networks. Every E1 line only occupy 64Kbps of channels spending when Ethernet data transmission. The factual available bandwidth of every E1 is 1.984Mbps. Automatically inspecting the number of the available channels of 4 channels of E1 and automatically distributing bandwidth. It is fit for redundant and bandwidth of E1 line. Support CRC error code threshold setting of every E1 branch. When error code rate of some branch is over the threshold, the system will automatically turn off and separate the E1 branch.  Turn off the separation function to achieve single-direction separation, which means it only cuts off the branch which is over the error code threshold in E1 lines, while transmission in the other direction is not influenced. It can carry out the dissymmetry of the two direction of Ethernet data transmission to be sure that there has the largest data transmission efficiency.  Satisfies the requirements of G.703, G.704, G.706, G.823 and I.431 of ITU. Support local system to reset the remote system.  Full set of alarm indication, automatically deal with all kinds of line problems. Detailed line alarm direction output, automatically deal with all kinds of line problems.
