The TBC-CT6008 series protocol converters are developed from the dedicated ASIC developed Ethernet to TDM stream reverse multiplexing equipment, its greatest feature is that from the FE (FX) interface Ethernet data through the packaging process after the formation of The EoPDH signal is mapped to the E1, and the Ethernet data is transmitted to the remote end through the PDH network and the SDH network. In the reverse direction, the EoPDH signal on the unified E1 port is demapped to the Ethernet (FE) port, In order to achieve the use of E1 on the Ethernet data for long-distance transmission or access.This interface converter can send and receive signals E1 channel point-to-point transmission RJ45 interface, E1 channel and Ethernet interconnection. Unlike a typical remote bridge, it supports flexible configuration of 1-8 E1 channels, automatically detects the number of E1s and selects available E1s, and allows for some transmission delay differences between E1 circuits. Single-line rate is 1920Kbit/s, 8-channel bandwidth up to 15360Kbit/s. When using the device at 10/100Mbps full/half duplex mode, can be connected to an Ethernet switch or hub, to fully utilize the existing telecommunications network resources to a large number of E1 circuits extend the transmission distance and the scope of application of Ethernet. It is a good solution for Ethernet broadband access. This product can be used for LAN interconnection, central office interconnection, video on demand, remote monitoring, E1 interface card switch and other fields.
