PT-RJ45-E1       E1 turned Ethernet protocol converter  

Item description: E1 turned Ethernet protocol converter

Type: PT- RJ45 - E1

Along with the telecom E1 access business develop continuously, through the E1 network realization of the Ethernet remote high speed Internet has been very common. And the traditional routers both Ethernet interconnection, and sometimes even just extended Ethernet distance, high cost. So people use a kind of Ethernet E1 bridge to replace the existing routing equipment to realize both Ethernet interconnected.

This protocol converter is a new low cost Ethernet interconnected bridge equipment, commonly known as Ethernet E1 bridge (also called Ethernet E1 protocol converter). Based on FPGA technology design, the E1 interface conforms to the ITU - T G. 703 agreement, Ethernet interface with 10 base-t standard, support 10 MBPS Ethernet rate, built-in clock crystal vibration timely clock recovery circuit, support line recovery clock, and local clock.

Features:
Later E1 line transmission Ethernet data, and to realize the function of bridge
Later support line recovery clock and local clock
Later E1 (g. 703) provide 120 ohm (RJ45) and 75 ohm (BNC)
Later with Ethernet MAC address filtering function
Later a data compression function
Later interface with 1500 v electromagnetic isolation protection and mm
