An apparatus and method for security of individual communications over a composite communications channel such as T1 or E1. The composite channel is digitized. Individual channels are separated, but identifying information of each channel is retained. A level of security can be chosen for each channel by digitally processing the selected call with a selected level of scrambling or encryption prior to passing the call to an end-user.
