GENERAL DESCRIPTION

The DS26518 is a single-chip 8-port framer and line

interface unit (LIU) combination for T1, E1, and J1

applications. Each port is independently configurable,

supporting both long-haul and short-haul lines. The

8-port SCT is software compatible with the DS26519

and nearly software compatible with the DS26528

and its derivatives.

APPLICATIONS

Routers

Channel Service Units (CSUs)

Data Service Units (DSUs)
