Abstract: A debugging assembly includes a modem including a control unit, a switch unit, and an RJ45 port. The control unit is coupled to the RJ45 port through the switch unit. The control unit is configured to detect a network connection status of the modem and transmit a control signal to selectively couple the switch unit to pins of the RJ45 port to selectively receive a network signal or a debugging signal.

Abstract: A device set in a multimedia cable network includes a first modem including a first module to receive a beacon. The first modem has a first frequency and the beacon has a second frequency. When the first frequency of the first modem is not available, the first modem checks whether the second frequency is available in the multimedia cable network.

Abstract: A modem includes a temperature detecting module, a frequency detecting module, and a power offset calculating module. The temperature detecting module detects a real-time-work temperature of the modem. The frequency detecting module obtains a real-time-work frequency of the modem. The power offset calculating module calculates a power offset by inputting the real-time-work temperature and the real-time-work frequency into a pre-stored calculating model and adjusts a power of the modem according to the calculated power offset. A method of adjusting power of the modem is also provided.

Abstract: A multimedia terminal adapter saves IP addresses of the multimedia terminal adapter and second communication devices as an IP address list, and relationships between the IP addresses of the second communication devices and user ports as a relationship list. The multimedia terminal adapter sends the IP address list to the first communication device, and receives a selected IP address of a selected second communication from the first communication device. The multimedia terminal adapter further searches one user port corresponding to the selected IP address, and opens the searched user port to establish a remote connection between the first communication device and the selected second communication device.
