Status Explanations for product status codes

Active: In Production.


The DS3181, DS3182, DS3183, and DS3184 (DS318x) integrate ATM cell/HDLC packet processor(s) with a DS3/E3 framer(s) and LIU(s) to map/demap ATM cells or packets into as many as four DS3/E3 physical copper lines with DS3-framed, E3-framed, or clear-channel data streams on per-port basis.
