DS2182A  
T1 Line Monitor Chip  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
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 many 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.  
Cꢀ Performs Framing and Monitoring Functions  
Cꢀ Supports Superframe and Extended Superframe  
Formats  
Cꢀ Four On-Board Error Counters:  
16-Bit Bipolar Violation
