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 the  
accumulation of errors for extended periods, which permits a single CPU to monitor a number of T1  
lines. Output clocks that are synchronized to the incoming data stream are provided for easy extraction of  
S-Bits, FDL bits, signaling bits, and channel data. The DS2182A meets the requirements of ANSI  
T1.231.
