Abstract: This invention discloses an interface card built in each single unit of a CTI system and connected to the Voice Processing Unit (VPU) of the single unit via local CT-BUS. On the transmitting side of an interface card, low-speed signals from the VPU in the single unit are multiplexed into a single high-speed signal and converted into LVDS signals. On the receiving side of the interface card, external high-speed LVDS signals are converted into low voltage TTL signals, demultiplexed into local CT-BUS compatible low-speed signals and sent to the VPU in the single unit. The invention also discloses a CTI system applying the interface card. The interface card and the CTI system applying the interface card feature low cost, simple and reliable connection, easy installation and operation, high reliability, large channel capacity and good expandability.

Abstract: An approach for process generation for computer telephony integration (CTI) of an integrated telecom platform, including the following steps. Step 1: The process input module receives the flow chart input by a user and saves it as a flow chart record file; Step 2: the process coversion module coverts the flow chart record file into the equivalent source codes and saves them as a flow chart coversion output file; Step 3: the process compilation module compiles the flow chart coversion output file and saves it as a flow chart compilation output file. The invention also announces a process generation system for an integrated telecom platform, including the process input module, the process coversion module and the process compilation module. The invention is an ideal system for various CTI applications, allowing easy and fast subsequent development as well as convenient system upgrade and maintenance.

Abstract: An approach for process execution for an integrated telecom platform including the following steps: (a) The process execution module loads the process dynamic link library according to the set process parameters; (b) process execution module dispatches process creating function to create the corresponding process data structure duplicate according to the set resource channel number; (c) use the event information to activate the process data structure duplicate to a process, then the activated process will call the process running function or system functional function to process the event packets of resource channels bound to it. This invention also offers a process execution system for an integrated telecom platform. This invention makes the system operates at a higher efficiency by directly dispatching the execution process through the process execution modules.

Abstract: An approach for module configuration management for an integrated telecommunication platform including the following steps: (a) the configuration management module sends the start instruction to the functional module and the digital signal processing module to start them respectively, and make the connection between the successfully started modules and the already started modules related to them; (b) the configuration management module sends the status detecting instruction to the functional module and the digital signal processing module, which will respectively feed back their current status to the configuration management module after they have received such a detection instruction; (c) the configuration management module will send instructions to the modules at upper level and those at lower level of the functional module and/or the digital signal processing module to disconnect them if the module is abnormal and does not feed back its status signal to the configuration management module.

Abstract: An integrated telecommunication service system, including one or more digital signal processing (DSP) modules processing voice signals and signaling and independent from each other. The DSP modules are connected to each other via communication and each of them is also connected to PSTN via communication. Each DSP module is also connected to the Network Switch via communication. The Network Switch is connected to one or more hosts via Ethernet. The hosts include the Configuration Management Module and one or more function modules. Each DSP module has an exclusive IP address. Each function module also has a corresponding IP address. The Configuration Management Module use such IP addresses to establish connection between the modules. The connected modules transmit data to each other via Ethernet protocol frames. The invention can reduce R&D time and provide good expandability by applying Ethernet connection and Configuration Management Module.
