The HJ-ICE01/02/04E protocol converter utilizes E1 communication lines to provide an 8M bandwidth data transmission channel for the internet. It connects two local area networks into two segments of a single network through transmission devices like optical terminals. It automatically learns MAC addresses, filters data packets based on the address table, and is transparent to the TCP/IP protocol. Widely used in public networks of telecom and mobile operators, as well as in specialized networks for post and telecommunication, electricity, banking, public security, military, railways, and large enterprises and institutions.
