中文摘要 | ISDN網路同時具備語音及數據通信功能,提高了通信服務品質,但現有PC (Personal Computer)若要接上ISDN網路,則需做適當轉換。本計劃為提供多媒體電信服務所需之數據通信功能,特發以多種數據服務為主之PC型ISDN終端機(PC Based ISDN Terminal, PCIT),其數據服務包括電路式(B通道 V.110、V.120)及分封式(B或D通道X.25)為加速計劃進行,我們採用與本所ISDN PABX計劃相同的PTXC(Real Time Executive in C)作業系統。PCIT硬體設計採用西門子Chip為主要通信元件。PCIT的測試以AT&T 5E5及Siemens 1TR6交換機為主。 |
英文摘要 | The Integrated Service Digital Network (ISDN), which supports voice and data communication simultaneously, upgrades the quality of transmission and service. Some adaptation are needed when the existing PC (personal Computer) is to connect to the ISDN. To meet the data communication need for multi-media telecommunication service, we have developed a PC based ISDN terminal (PCIT) which provides several services for data communication, including circuit mode (B channel V. 110, V.120) and packet mode (B or D channel X.25). To smooth and facilitate its development, we adopted the RTXC (Real-Time Executive in C) operating system which is also used by ISDN PABX, another project at TL. Fir the hardware of PCIT, we have adopted the Siemens chip as the key communication component. PCIT has been tested mainly on AT&T 5E5 and Siemens 1TR6 switching system. |
