在T1 / E1到以太网转换器是一个单端口T1或E1和以太网桥接,可提供高速的局域网到广域网连接。
以太网T1转换器是利用TDM电信基础设施的以太网扩展设备(的T1; DS3; SDH或携带的T1微波链路)。 它以太网数据到T1帧格式转换为传输在现有的TDM(T1)的链接,然后将T1重新转换回以太网数据的远端终端,以桥接两个以太网LAN在现有T1为基础的电信网。 该装置可有效地利用现有的TDM网络来传输以太网数据低投资。
装置 支持这两种协议E1和T1,可以作为以太网T1转换器或以太网E1转换器。 它必须配合的E1 / HDB3或T1 / B8ZS作为线路接口,E1可任成帧N * 64Kbps的(N = 1-31)或无框2048Kbps,这也被称为信道化和unchannelization。 在成帧模式,它支持CAS / CCS(30和31时隙)的选择,CRC4自动适应。 T1通过完全透明的非成帧1.544Mbps的带宽连接远程局域网。 传输时钟可以从接收信号G. 703线,也可以在内部时钟模式下工作恢复。

应用:
The T1/ E1 to ethernet converter is a single port T1 or E1 with Ethernet Bridging that provides high-speed LAN-to-WAN connectivity.
Ethernet over T1 converter is an Ethernet extension device utilizing TDM telecom infrastructure (of T1; DS3; SDH or microwave links carrying T1s ) . It converts the Ethernet data into T1 frame format for transmission over the existing TDM (T1) links and then re-converts the T1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet LANs over the existing T1-based telecom network. The device can effectively utilize the existing TDM network to transport Ethernet data with low investment.
The device support two protocol E1 and T1, can used as ethernet over T1 converter or ethernet over E1 converter.It is collocated with E1/ HDB3 or T1/ B8ZS as line interface, E1 can be either framed N*64Kbps (N=1-31) or unframed 2048Kbps, which are also known as channelization and unchannelization. Under the framed mode, it supports options of CAS/ CCS (30 & 31 time slot) , and CRC4 auto-adapt. T1 connects remote LAN through fully transparent unframed 1.544Mbps bandwidth. Transmission clock can be recovered from receiving signal G. 703 lines and also can work in internal clock mode.
