DESCRIPTION  
The DS2186 T1/CEPT Transmit Line Interface Chip in-  
terfaces user equipment to North American (T1–1.544  
MHz) and European (CEPT–2.048 MHz) primary rate  
communications networks. The device is compatible  
with all types of twisted pair and coax cable found in  
such networks.  
Short loop (DSX–1, 0 to 655 feet) and long loop (CSU; 0  
dB, –7.5 dB and –15 dB) pulse templates found in T1  
applications are supported. Appropriate CCITT recom-  
mendations are met in the CEPT mode.  
Application areas include DACS, CSU, CPE, channel  
banks, and PABX–to–computer interfaces such as DMI  
and CPI. The DS2186 supports ISDN–PRI (Primary  
Rate Interface) specifications.  
Key on–chip components include: programmable wave  
shaping circuitry, line drivers, remote loopback, and  
zero suppression logic. A line–coupling transformer is  
the only external component required.
