Abstract

The invention relates to the technical field of automatic testing of product production, in particular to a method for monitoring output power of a CMTS (Cable Modem Terminal System). The method comprises the following steps of connecting a configuration-testing Cable Modem and the CTMS; controlling the measurement-matching Cable Modem to be automatically locked to a frequency band assigned by the CMTS; obtaining uplink and downlink power of the configuration-testing Cable Modem through an order; comparing the obtained uplink power and the obtained downlink power with a target value, automatically locking a screen of a testing computer if the obtained power is not in a range allowed by the target value, and indicating to check a testing environment or the working state of the CMTS. According to the method for monitoring the output power of the CMTS, disclosed by the invention, the output power of the CMTS can be automatically monitored in real time, and the output power of a coaxial cable linked with the CMTS does not need to be manually and continuously measured, so that a large amount of labor is saved, and the normality of the output power of the CMTS during a testing process is also ensured.

Description

technical field [0001] The invention relates to the technical field of product production automation testing, in particular to a method for monitoring output power of a CMTS. Background technique [0002] CMTS (Cable Modem Terminal Systems), CMTS is a device that manages and controls Cable Modem, and its configuration can be completed through the Console interface or Ethernet interface. The configuration contents mainly include: downlink frequency, downlink modulation mode, downlink level, etc. The downlink frequency can be set arbitrarily within the specified frequency range, but in order not to interfere with the signals of other channels, it should be selected at the specified frequency point by referring to the channel division table of cable TV. The choice of modulation method should consider the transmission quality of the channel. In addition, DHCP, IP address of TFTP server, IP address of CMTS, etc. must be set. After the above settings are completed, if there is ...
