PURPOSE: A method for increasing an internal line capacity in an integrated service system is provided to supply various services which are generated simultaneously, and manage the information on the state of each slot card, by including a serial bus with a large amount of line channels, and allocating a service to an unused channel, and thereby increase the internal line capacity. CONSTITUTION: A serial bus(110) is used for transmission of the state information of the slot card and pulse code modulation(PCM) data. A data bus(120) is used for transmission of the data which corresponds to various service request of subscribers. A public switching telephone network(PSTN) is adapted for transmission of various service request signals from the subscribers and requested services. A plurality of multiple vocoder circuits(MVC)(140a-140n) switch the service request signals from the subscribers and processes them therein. A main processor(150) controls the system and allocates the requested services to the unused channels in order to supply corresponding services. An expanding block(160) expands the MVCs(140a-140n) in response to the increase of the services.
