Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cat car for testing CMTS. Background technique [0002] Cable Modem is translated into cable modem, commonly known as "cat" or "broadband cat". The "cat cart" is an invention that changes the fixed "cat rack" that is common in laboratories into a mobile one. CMTS is the abbreviation of Cable Modem Termination System, which is the most important device in the cable TV broadband network. Unlike the vast majority of home users in China who access the Internet through the telephone line of China Unicom or China Telecom, most families in Europe and the United States use the cable TV line to access the Internet. In the previous 1.0 and 2.0 eras, R&D and manufacturing were mainly in the hands of several major American manufacturers such as Cisco, Motorola, and ARRIS, and large-scale CMTS (referred to as Big C) were the mainstays. A single device supported 1,000-64,000 users to...
