产品功能： BD-8E1-ETH转换器采用反向多路复用技术传输的10 / 100BaseT数据与粘接多路E1通道，从而实现1-8个E1通道和以太网接口之间的转换。 它可以发送信号点至点从E1通道RJ45接口实现E1通道和以太网之间的连接。 依据从一般长途桥不同，此转换器支持为1〜8个频道的E1灵活的配置和能够检测E1通道的数目和选择可利用信道。 在此期间，传输延迟时间的一定差异是允许的中E1通道。 线路速率为1968Kbit / s的1个E1信道和带宽可以达到15744Kbit / s的8路E1通道。 当个10 / 100Mbps全双工/半双工模式下使用，该设备可以与以太网交换机或集线器（集成电路机）连接，充分利用了大量的E1通道的当前电信网络扩展以太网的传输距离和应用范围 。 它是用于连接以太网宽带的最佳解决方案。 此产品可以在许多领域得到应用，例如局域网的连接和端局，视频点播（VOD），远程监视和开关E1接口。

产品特点：

  • 实现以太网数据在1〜8路E1的透明传输。
  • 以太网支持10M / 100M，全双工/半双工自动negociation，支持VLAN。

    应用：

    • Product function: BD-8E1-ETH converter uses reverse multiplexing technology to transmit 10/100BaseT data with bonding multi E1 channels, thus realizing conversion between 1-8 E1 channels and Ethernet interface. It can transmit signals point-to-point from E1 channel to RJ45 interface to realize connection between E1 channel and Ethernet. Being different from general long-distance bridge, this converter supports flexible configuration of 1 to 8 channels E1 and can detect the number of E1 channel and choose available channel. In the meantime, certain difference of transmitting delay is allowed among E1 channels. Line rate is 1968Kbit/ s for one E1 channel and bandwidth can reach 15744Kbit/ s for 8 E1 channels. When used in 10/100Mbps half/ full duplex mode, this equipment can be connected with Ethernet switch or hub (integrated circuit machine) to expand transmitting distance and application scope of Ethernet by making full use of large number of E1 channels in current telecommunication network. It is an excellent solution for connecting Ethernet broadband. This product can be applied in many fields such as connection of LAN and end offices, video ordering (VOD) , remote monitor and E1 interface of switches.

    Features:

  • Realizes transparent transmission of Ethernet data in 1 to 8 E1 channels.
  • Ethernet supports 10M/ 100M, full/ half duplex auto-negociation, supports VLAN.
  • Ethernet port supports AUTO-MDIX (cross over and straight through auto-adapt) .
  • Setting CRC alarm limitation to auto isolate lines with low transmitting quality (being cut single-directionally) ; when error code rate of one direction in 2M branch exceeds the limitation, this direction is cut and the other direction will not be affected, namely the two transmitting directions of Ethernet can be unsymmetrical.
  • Allow 8 E1 channels up to 10ms transmission delay. When the delay exceeds allowed limit range, it can stop transmitting data automatically.
  • Has 2 loop back functions: E1 local loop, E1 remote loop.
  • Supports Dynamic Ethernet MAC address (4096) with local address filter function.
  • E1 interface compatible with ITU-T G. 703, G. 704, and G. 823. not supporting signal timeslot.
