  2. What is it? Sample Application developed in C++ Can be used to record an FSK signal once the call is established Uses Media Bypass feature

  3. Overall Architecture Description (1/2) • At start-up the main thread will create the FSK Receive Entry container. • The main thread will then spawn the event thread. • The event thread is used to handle asynchronous events from the PIKA driver. • Only incoming calls will be handled. • Once an incoming call is answered, the PK_BYPASS_FSK_Start call is made to bypass the GrandPrix media processing. • This will in turn call • PKX_CHANNEL_GetBypassInfo : Get Media Stream handle • PKH_FSK_GetConfig : Get FSK configuration • PKH_FSK_SetConfig: Set FSK Configuration • PKH_QUEUE_Attach : Attach media stream handle to HMP Queue • PKX_CHANNEL_EnableBypass : Enable Bypass for Channel • PKH_FSK_RxStart: Start Low Level FSK recording • PKH_FSK_GetRxData : Handle FSK events

  4. Overall Architecture Description (2/2) • Once the FSK is deemed completed, the PK_BYPASS_FSK_Stop call is made to stop the bypass feature. • This will in turn call • PKH_FSK_RxStop: Stop Low Level FSK recording • PKX_CHANNEL_DisableBypass : Disable Bypass for Channel • For cleanup purposes, the PK_BYPASS_FSK_Cleanup is called before exiting the application

  5. Getting Started • Install the PIKA Low Level HMP API and PIKA High Level on a PC ( 2.7.x or newer ) as described in the Getting Started Guide • Install the Analog Trunk board in the PC • Download, Compile, and run the FSK Bypass Sample application
