FEATURES
§ Performs framing and monitoring functions
Supports Superframe and Extended Super-
frame formats
§ Four onboard error counters
– 16-bit bipolar violation
– 8-bit CRC
– 8-bit OOF
– 8-bit frame bit error
§ Indication of the following
– yellow and blue alarms
– incoming B8ZS code words
– 8 and 16 zero strings
– change of frame alignment
– loss of sync
– carrier loss
§ Simple serial interface used for config-
uration, control and status monitoring
§ Burst mode allows quick access to counters
for status updates
§ Automatic counter reset feature
§ Single 5V supply; low-power CMOS tech-
nology
§ Available in 28-pin DIP and 28-pin PLCC
§ The DS2182A is upward-compatible from
the original DS2182
The updated DS2182A includes the following
changes from the original DS2182:
§ Ability to count excessive zeros
§ Severely Errored Framing Event indication
§ Updated AIS detection
§ Updated RCL detection
§ AIS and RCL alarm clear indications

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.
