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.
