Description

FULL DATA SHEET (PDF, 11.3MB) Download   E-Mail The DS33R11 extends a 10/100 Ethernet LAN segment by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over a T1/E1/J1 data stream. 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. The DS33R11 can operate with an inexpensive external processor.
