An enhanced services communication system (10) has a standard services region and an enhanced services region (58) in which communication may be carried out. Subscriber units (49, 109) located within the enhanced services region (58) request enhanced services that include dynamic allocation of bandwidth. A variable bandwidth repeater switch (42) evaluates the availability of requested bandwidth and allocates the bandwidth to the subscriber units (49, 109) when available. Transmission of data using enhanced services occurs using wideband wired interfaces (115), wideband wireless interfaces (70), or PSTN interfaces (103). Selection of dynamic allocation of bandwidth may rely upon economic, propagation duration, or link quality factors, among other considerations.
