Abstract

The invention discloses a multifunctional communication device. The multifunctional communication device is composed of a controller system circuit, eight south Ethernet interface circuits, four south isolated asynchronous serial communication interface circuits, four south SULIM interface circuits, a north Ethernet interface circuit and a power system circuit. The eight south Ethernet interface circuits are respectively composed of a nine-port Ethernet controller and an isolation transformer. The four south isolated asynchronous serial communication interface circuits are respectively composed of an asynchronous serial communication controller, an optical coupler isolation circuit and an RS-23 level conversion circuit. The four south SULIM interface circuits are respectively composed of an SULIM circuit, an isolation transformer and a line control switch circuit. The multifunctional communication device is applied to networking of an access network test device and simple in structure and provides abundant communication interfaces.

Description

technical field [0001] The invention relates to a multifunctional communication device applied to communication interface conversion, which is applied to the networking of access network test equipment and belongs to the technical field of communication. Background technique [0002] With the construction of my country's data communication network and the vigorous development of data communication services, in order to improve user satisfaction and service quality, operators need to configure a variety of operation and maintenance equipment to meet the measurement and maintenance needs of various business lines. Because these operation and maintenance equipment provide various control interfaces, such as Ethernet interface, asynchronous serial interface and SULIM interface, etc., in addition, the network management of the operation and maintenance equipment generally only configures the Ethernet interface. The various control interfaces of the operation and maintenance equip...
