Industry's First Multiport, T3/E3 ATM/Packet PHYs with Built-In Line Interface Units
|
Status
Active: In Production.
Description
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.
