摘要：互操作性是一個(gè)系統(tǒng)經(jīng)過很少甚至無需系統(tǒng)操作員介入而實(shí)現(xiàn)與其它系統(tǒng)協(xié)同工作的能力。系統(tǒng)的互操作性使其有可能為其它系統(tǒng)提供服務(wù)或接受其它系統(tǒng)的服務(wù),使得不同廠商的系統(tǒng)能夠協(xié)同工作。本應(yīng)用筆記介紹如何設(shè)置DS34S132 TDM-over-Packet (TDMoP) IC，使其與其它TDMoP器件實(shí)現(xiàn)互操作。 引言 毋庸諱言，當(dāng)今的通信系統(tǒng)需要不同設(shè)備和設(shè)備之間的復(fù)雜交互。隨著技術(shù)的進(jìn)步，互操作性也變得更加重要。互操作性是一個(gè)系統(tǒng)經(jīng)過很少甚至無需系統(tǒng)操作員介入而實(shí)現(xiàn)與其它系統(tǒng)協(xié)同工作的能力。系統(tǒng)的互操作性使其有可能為其它系統(tǒng)提供服務(wù)或接受其它系統(tǒng)的服務(wù)，從而使不同廠商的系統(tǒng)能夠協(xié)同工作。 本應(yīng)用筆記著重介紹Maxim TDM-over-Packet (TDMoP) IC，DS34S132。文章介紹了在DS34S132與其他廠商TDMoP器件之間實(shí)現(xiàn)互操作性的設(shè)置要求。

Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test. Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- grammer write nonvolatile memories before assembling the board, the in-cir- cuit tester writes them during in-circuit testing operations. Many Teradyne Z18- series testers are now in use loading code into nonvolatile memories, micro- controllers and in-circuit programmable logic devices. The purpose of this note is to explain how the Z18 approaches the writing task for Atmel AT89C series IC’s, so that designers of boards using these chips can get the best results.

In order to meet the needs of heat charging mode changing， a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow，using the IC card to record the prepaid amount and the current price of heat. The user?蒺s heating costs is calculated according to energy consumption and current price， according to actual heating costs and prepaid amount，the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption

This application note describes how to decode standard DTMF tones using the minimum number of external discrete components and a PIC. The two examples use a PIC which has an 8 bit timer and either a comparator or an ADC, although it can be modified for use on a PIC which has only digital I/O. The Appendices have example code for the 16C662 (with comparator) and 16F877 (using the ADC). As the majority of the Digital Signal Processing is done in software, little is required in the way of external signal conditioning. Software techniques are used to model the individual elements of a DTMF Decoder IC.
