Abstract

An E1/Ethernet data conversion unit comprises a main processing unit, which is respectively connected with a network management control unit, an E1 interface circuit unit, an Ethernet interface circuit unit, an LED indication unit, a DIP control unit, an SDRAM storage unit, a clock and a reset circuit unit. The E1/Ethernet data conversion unit is user terminal access equipment developed and produced by adopting specific integrated circuit, and can provide the most economic solution scheme for the E1 network access at the minimum cost. In addition, the E1/Ethernet data conversion unit supportsHDB3 (high density bidirection 3), and can provide continuous error monitor, performance polling and online diagnosis. The E1/Ethernet data conversion unit can principally achieve data conversion fromE1 network to the Ethernet. The development of the E1/Ethernet data conversion unit is convenient in management and can meet the requirement of costumers.

Description
