DESCRIPTION  
The DS2187 T1/CEPT Receive Line Interface chip interfaces 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 termination electronics.  
Application areas include DACS, CSU, CPE, channel banks, and PABX-to-computer interfaces such as  
DMI and CPI.
