T1 Line Monitor

DESCRIPTION The DS2182A T1 line monitor chip is a monolithic CMOS device designed to monitor real-time performance on T1 lines. The DS2182A frames to the data on the line, counts errors, and supplies detailed information about the status and condition of the line. Large on-board counters allow th

T1線路監(jiān)測器芯片

DS2182A T1線路監(jiān)視器是一款專為監(jiān)視T1線路實時性能而設(shè)計的全集成CMOS器件。DS2182A與線上數(shù)據(jù)保持幀同步，計算誤碼數(shù)，并提供關(guān)于線路狀態(tài)與狀況的詳細信息。片上大容量計數(shù)器可以在很長的時間內(nèi)累計誤碼數(shù)，允許單個CPU監(jiān)視大量T1線路。輸出時鐘同步于輸入數(shù)據(jù)流，可用于方便地檢出S位、FDL位、信令位以及通道數(shù)據(jù)。DS2182A符合ANSI T1.231的規(guī)定。 \n? 完成成幀與監(jiān)測功能 \n? 支持超幀與擴展超幀格式 \n? 四個片上誤碼計數(shù)器： \n? 16位雙極性違規(guī) \n? 8位CRC \n? 8位OOF \n? 8位幀位錯誤 \n? 指示以下信息： \n? 黃色與藍色告警 \n? B8ZS編碼字輸入 \n? 8和16個零串 \n? 幀位改變 \n? 同步丟失 \n? 載波丟失 \n? 提供簡單的串行接口，用來配置、控制，以及狀態(tài)監(jiān)測 \n? 突發(fā)模式快速訪問計數(shù)器以更新狀態(tài) \n? 計數(shù)器自動復(fù)位功能 \n? 5V單電源供電，低功耗CMOS技術(shù) \n? 采用28引腳DIP和28引腳PLCC封裝 \n? DS2182A向上兼容于最初的DS21;
