Abstract
A method for operating a communications system is disclosed. At a first point in time, the communications system is operated using a first TDM switch/MUX controlling a first set of TDM streams operating at a first frequency. At a second point in time, a second TDM switch/MUX is installed in the communications system which controls the first set of TDM streams operating at the first frequency and also controls a second set of TDM streams operating at a second frequency that is different as compared to the first frequency. The second TDM switch/MUX couples TDM streams to and from the communications system at the first frequency, while concurrently coupling TDM streams to and from the communications system at the second frequency, and an upgradable switch/MUX capability is provided in the communications system.
