Description
The DS33R41 extends a 10/100 Ethernet LAN segment by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over four interleaved T1/E1/J1 lines using a robust, balanced, and programmable inverse multiplexing. Four integrated T1/E1/J1 transceivers provide framing and line interfacing functionality.

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.
