DS2182A
T1 Line Monitor Chip
www.maxim-ic.com
GENERAL 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 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.
