Abstract: In the telecommunication industry it is often necessary to design equipment that interfaces with existing telecommunication systems. To ensure that a piece of equipment functions properly in a legacy system, several application-d...

Abstract: The DS21Q55 is a quad multichip module (MCM) device featuring independent transceivers that can be software configured for T1, E1, or J1 operation. Each is composed of a line interface unit (LIU), framer, HDLC controllers, and a ...

Abstract: Application note 398 is a design guide that has all the information necessary for a designer to build a network interface circuit for a piece of telecommunications equipment using Dallas Semiconductor T3, E3, or STS-1 line interf...

Abstract: The 3-wire extended system information bus (ESIB) function allows the interrupt status or other user-selectable alarm status information for multiple single chip transceivers (SCTs) to be accessed in a single read cycle. ...

Abstract: This application note shows how to use undocumented settings to modify output amplitudes. IntroductionThis application note provides the register settings for the DS2148/DS21348/DS21Q48/DS213Q48 and D...

Abstract: This application note describes how to modify the pulse shape (amplitude, rise- and fall-times) of Dallas DS3150, DS315x, and DS325x Line Interface Units (LIUs). IntroductionThis application note desc...

Abstract: This application note describes the JTAG hardware boundary scan functions of the quad port single chip transceivers (SCTs). The JTAG functionality for the quad port devices is essentially the same as four separate DS21x5y devices...

Abstract: Application Note 403 describes the software considerations when migrating an existing design based on the DS2155 T1/E1/J1 single chip transceiver (SCT) to the DS26401 T1/E1/J1 octal framer. In comparison, the Dallas Semiconductor...

Abstract: Application Note 407 provides a focused view of the functionality of the Dallas Semiconductor/Maxim DS2148/DS21348 selectable E1 or T1 line interface unit (LIU) in hardwar...

摘要：利潤率優(yōu)先于可靠性，這是在設(shè)計任何系統(tǒng)時都會被考慮到的一個重要問題。尤其是在電信行業(yè)，日益增強(qiáng)的競爭要求從購買的設(shè)備中獲得更多的效益。服務(wù)提供商則要求他...

Abstract: This application note shows how to connect our enhanced bit error-rate tester (BERT) to our DS3/E3 framer using a ITU O.151 pattern in ungapped clock mode. IntroductionThis application note demonstrat...

Abstract: This application note describes the hazard of switching frame mode while a T1 line is active. When using or testing T1 systems, it may be possible to switch between the D4 and ESF framing patterns during live operation. Under cer...

摘要：本應(yīng)用筆記介紹怎樣實現(xiàn)Dallas Semiconductor DS2156DK開發(fā)板的DS2156 Utopia II總線與DK101或DK2000演示母板的連接。DK101是低成本演示母板，用于評估Dallas Semiconductor電信IC。IC安裝...

Abstract: This application note provides a detailed description for using the SLC-96 multiframe in the DS2155, DS21Q55, and DS2156. Register values and an example flowchart for software routines allow the user to quickly implement SLC-96 i...

摘要：DS31256 Envoy HDLC控制器在發(fā)送數(shù)據(jù)包之前的初始化順序。 概述按照設(shè)計，DS31256上電以后不會控制PCI總線。所有的物理端口(端口0至15)發(fā)送全1 (非HDLC空閑碼)...

摘要：本篇應(yīng)用筆記介紹如何調(diào)整DS3151、DS3152、DS3153和DS3154的脈沖波形。盡管DS315x的信號脈沖總是滿足規(guī)范要求的，但有時候，這種脈沖形狀并不恰好是客戶最想要的。本應(yīng)用筆記...

摘要：具有多端口T1/E1/J1線卡的現(xiàn)代通信系統(tǒng)通過增加冗余來滿足電信網(wǎng)絡(luò)的高可用性要求。過去，這些系統(tǒng)曾經(jīng)用繼電器來實現(xiàn)N＋1冗余切換。隨著每個線卡上的T1/E1/J1端口數(shù)和每...

Abstract: This application note will describe what is needed to design a T3/E3/STS-1 Fiber to Copper Media Converter. Such a device will take the copper signal and convert it to an optical signal to be transported over a fiber link. A pair...
