中文摘要 | CAM是ISDN PABX的控制中心,所有週邊模組都透過IMC(Inter-Module-Communication)鏈路傳送資料到CAM;經過處理後,CAM再送出控制指令到各相關模組,因此CAM需有極大的計算能力來處理各模組送來的資料,也需有能力來處理IMC鏈路上的大量資料進出,CAM硬體及軟體卽為了滿足這些需求而設計。共分為CPU板、通訊電路板、記憶體板、背板等四種,而在通訊電路板上設計了軟體程式來專門管理IMC鏈路的資料進出。本文說明了CAM硬體架構,每種電路板的架構以及軟體程式的架構。 |
英文摘要 | The control Administration and Maintenance Module (CAM) acts as the control and administration center of the ISDN PABX. It receives control and status from all the peripheral modules, and send out commands and control information to the relative modules. Therefore, CAM needs powerful computing capacity to process the information from each module, it also has to handle large volume of traffic in Inter-Module-Communication (IMC) link. CAM hardware is designed to meet these requirements, four kinds of circuit board are designed: CPU_Bd, COM_Bd, Memory_Bd, and backplane. A firmware program is also designed for the COM_Bd to handle information transmitting and receiveing in IMC Link. This report describes the CAM hardware architecture, block diagrams of each circuit board, and firmware structure. |
