Abstract:
An apparatus for reducing transmission errors in a communications system, the apparatus transmitting data over the communications system at different rates, the apparatus comprising:a baseband ring detector, the baseband ring detector configured to detect baseband ringing in the communications system, wherein when the baseband ring detector detects the presence of baseband ringing in the communications system, the baseband ring detector causes the rate at which the apparatus is transmitting data over the communications system to be reduced to a first transmission rate, wherein the baseband ring detector is also configured to detect an absence of baseband ringing in the communications system, wherein when the apparatus is transmitting data over the communication system at the first transmission rate and the baseband ring detector detects an absence of baseband ringing on the communications system, the baseband ring detector causes the apparatus to transmit data over the communication system at a second transmission rate.
