Protocol converter series can implement the conversion between single E1 protocol port and protocol ports of V.35, V.24, RS232 or Ethernet in the transmission network; it can be extensively used in various accessing conditions for operators and industrial customers, such as DDN, ATM, and for the conversion between router and E1 port, or the occasion where Ethernet are interconnected at separated net sites by SDH or other transmission equipment.
1、The equipment can provide local, remote loop-back functions, commanded remote device loop-back and pseudo-random code testing function; loop-back function can be used without influence on normal network data communication and will not result in the meltdown of network;
2、E1 port can support 120 Ω/75 Ω resistance simultaneously;
3、V.35 user port can support N*64K (N=1~32) adaptive rate, and can support internal, external and slave clock modes, so as to be adapted to various applications; and it can work under DTE and DCE modes;
4、V.24 port can support a rate of 64K or 128K (optional), and can conduct transmission at any specified time-slot in E1 port; and it can work under DTE and DCE modes;
5、RS232 port can support the an adaptive rate lower than 115.2K;
6、Ethernet port can support N*64K (N=1~32) adjustable rate, and can support four channels of Switched Ethernet ports and can be channel-isolated; Ethernet mode can support 10M/100M semi-duplex and 10/100M full-duplex modes and adaptive mode (optional), and support VLAN protocol;
7、Ethernet protocol convertor can detect the sending and receiving data warning of E1 port automatically, and switch off Ethernet function automatically;
