The DS33Z41 extends a 10/100 Ethernet LAN
segment by encapsulating MAC frames in HDLC or
X.86 (LAPS) for transmission over up to four
interleaved PDH/TDM data streams using robust,
balanced, and programmable inverse multiplexing.
The Interleave Bus (IBO) serial link supports
seamless bidirectional interconnection with Dallas
Semiconductor's T1/E1 framers and transceivers.
The device performs store-and-forward of packets
with full wire-speed transport capability. The built-in
Committed Information Rate (CIR) Controller
provides fractional bandwidth allocation up to the
line rate in increments of 512kbps.
