Solution Approach 1:

The system implements self-service by automatically detecting configuration changes at data exchange interfaces and generating signaling information for bandwidth reconfiguration without manual intervention. The processing unit monitors circuit-switched data activity, determines when reconfiguration is needed, and autonomously manages the entire reconfiguration process, improving adaptability while reducing operational complexity.

Solution Approach 2:

The system uses feedback mechanisms where the processing unit continuously monitors configuration changes at data exchange interfaces and adjusts bandwidth distribution accordingly. The signaling information inserted into frames provides feedback to the receiving end, enabling coordinated reconfiguration that adapts to changing data rate requirements while maintaining simple operation.

AI summary

A processing unit provides circuit-based data to a dynamically configurable modem to implement a framing, multiplexing, coding, and modulation scheme adapted to the transmission conditions. Bandwidth is allocated between circuit-based and packet-based data. Upon detection (301) of a configuration change at at least one circuit-based data exchange interface, the processing unit inserts (303) into a frame concatenating the circuit-based data a signaling message representing a request to change the bandwidth allocation, and, upon receiving (304) a positive response, reconfigures (305) the modem, maintaining the coding and modulation scheme and modifying the circuit-based data rate.
