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.
