DS26514  
4-Port T1/E1/J1 Transceiver  
______________ General Description  
_______________________ Features  
♦
Four Complete T1, E1, or J1 Long-Haul/  
Short-Haul Transceivers (LIU Plus Framer)  
The DS26514 is a 4-port framer and line interface  
unit (LIU) combination for T1, E1, J1 applications.  
Each port is independently configurable, supporting  
both long-haul and short-haul lines. The DS26514  
single-chip transceiver (SCT) is software and pinout  
compatible with the 8-port DS26518. It is nearly  
software compatible with the DS26528 and its  
derivatives.
