DESCRIPTION
The DS2186 T1/CEPT Transmit Line Interface Chip interfaces 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.

FEATURES
• Line interface for T1 (1.544 MHz) and CEPT (2.048 MHz) primary rate networks
• On–chip transmit LBO (line build out) and line drivers eliminate external components
• Programmable output pulse shape supports short–and long–loop applications
• Supports bipolar and unipolar input data formats
• Transparent B8ZS and HDB3 zero code suppression modes
• Compatible with DS2180A T1 and DS2181A CEPT Transceivers DS2141A T1 and DS2143 E1 Controllers
• Companion to the DS2187 Receive Line Interface and DS2188 T1/CEPT Jitter Attenuator
• Single 5V supply; low–power CMOS technology
