GENERAL DESCRIPTION 
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.
