Active: In Production.

Description

The DS26518 is an 8-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 DS26518 Single-Chip Transceiver (SCT) is software and pinout compatible with the 4-port DS26514. It is nearly software compatible with the DS26528 and its derivatives.
