Data calls using both constant bit rate and variable bit rate connections

A software product for processing a data call comprising:

• communication software operational when executed by a processor to direct the processor to receive signaling for the data call into a first call processing system, process the signaling to generate a first instruction to set up a constant bit rate connection for the data call between the first call processing system and a second call processing system, and process the signaling to generate a second instruction to set up a variable bit rate connection between the first call processing system and the second call processing system;
• and
• a software storage medium operational to store the communication software.

A call processing system for processing a data call, the call processing system comprising:

• a signaling processor configured to receive signaling for the data call, process the signaling to generate a first instruction to set up a constant bit rate connection for the data call between a first routing system and a second routing system, and process the signaling to generate a second instruction to set up a variable bit rate connection between the first routing system and the second routing system;
• and
• the first routing system configured to receive and process the first instruction to set up the constant bit rate connection for the data call with the second routing system, receive and process the second instruction to set up the variable bit rate connection with the second routing system, and receive and transfer data through the constant bit rate connection and the variable bit rate connection to the second routing system.

A communication system for processing a data call, the communication system comprising:

• a first call processing system configured to receive signaling for the data call, process the signaling to generate a first instruction to set up a constant bit rate connection for the data call between the first call processing system and a second call processing system, generate a second instruction to set up a variable bit rate connection between the first call processing system and the second call processing system to handle peak bursts of the data call based on the processing of the signaling, and transfer data to the second call processing system through the constant bit rate connection and the variable bit rate connection;
• and
• the second call processing system configured to exchange data through the constant bit rate connection and the variable bit rate connection with the first call processing system.
