DESCRIPTION
The DS2182A T1 Line Monitor Chip is a monolithic
CMOS device designed to monitor real-time perform-
ance on T1 lines. The DS2182A frames to the data on
the line, counts errors, and supplies detailed informa-
tion about the status and condition of the line. Large on-
board counters allow the accumulation of errors for ex-
tended 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 ex-
traction of S-Bits, FDL bits, signaling bits, and channel
data. The DS2182A meets the requirements of ANSI
T1.231.
