DS2187
Receive Line Interface
DS2187
022798 1/9
FEATURES
Line interface for T1 (1.544 MHz) and CEPT (2.048
MHz) primary rate networks
Extracts clock and data from twisted pair or coax
Meets requirements of PUB 43801, TR 62411, and
applicable CCITT G.823
Precision on–chip PLL eliminates external crystal or
LC tank - no tuning required
Decodes AMI, B8ZS, and HDB3 coded signals
Designed for short loop applications such as terminal
equipment to DSX–1
Reports alarm and error events
Compatible with the DS2180A T1/ISDN Primary Rate
and DS2181A CEPT Transceivers, as well as
DS2141A T1 and DS2143 E1 Controllers
Companion to the DS2186 T1/CEPT Transmit Line
Interface and DS2188 T1/CEPT Jitter Attenuator
Single 5V supply; low–power CMOS technology

DESCRIPTION
The DS2187 T1/CEPT Receive Line Interface Chip in-
terfaces user equipment to North American (T1 1.544
MHz) and European (CEPT 2.048 MHz) primary rate
communication networks. The device extracts clock
and data from twisted pair or coax transmission media
and eliminates expensive discrete components and/or
manual tuning required in existing T1 and CEPT line ter-
mination electronics.
Application areas include DACS, CSU, CPE, channel
banks, and PABX–to–computer interfaces such as DMI
and CPI.
