Product Overview

HXMJ-MIT101 is an integrated access terminal based on the next generation network (NGN),belongs to the terminal device of the NGN network access layer. The device can implement the telephone voice service (and fax service), data and video services communications on IP network by using different transmission media,and provides three kinds of remote interfaces Voice service can work with Asterisk, OpenSer and other standard SIP Server, and supports standard SIP,H.323 protocol.

HXMJ-MIT101 device has three transmission ports,they are 1 HDSL, 1 E1 and 1 optical Ethernet (FX). The device provides 8 analog voice ports to meet there quirements of on-site voice service, provides 8 Ethernet ports and 1 composite video broadcast signal (CVBS) port.

HXMJ-MIT101 device can be used for point-to-point connection, and can also interwork with soft-switch stored-program control exchange (SPC exchange) such as SOPHO-IS3000 in market to realize extension agent function. The device configuration management adopts Web Server to configure system or monitor the real-time operation status of device through Webpage browsing in the terminal computer.
