| Abstract: |
| First,we discuss the problem and method adout how to integrate circuits in each parts of MODEM.Second,a full duplex MODEM,which supports V.22bis,V.22A&B,Bell 212A,V.21and Bell 103,is presented,The MODEM is implemented by 89026,we introduces its system function ,hardware configuration and software function.The system ,which also can be easily integrated with the other system,with small volume,good flexibility,low cost and powerful function is an ideal low-speed MODEM. |
