Abstract
A method is provided for interfacing telecommunication devices. A base unit is connected to a landline for wireless communication. The base unit has a power supply operating at a power supply frequency. A mobile unit is provided for wireless communication with the base unit. The base unit is interfaced to the mobile unit using an interface protocol that has a plurality of frames. Each frame is for transmitting signals from the mobile unit to the base unit and from the base unit to the mobile unit. The frames have a specified frame length. An interference frequency is detected at either the base unit or the mobile unit. The interference frequency is compared with the power supply frequency. The frames are synchronized with the power supply and the specified frame length is adjusted based on the power supply frequency when the interference frequency and the power supply frequency are substantially the same.
