Status

Active: In Production.

Description

The DS33Z44 extends four 10/100 Ethernet LAN segments by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over four PDH/TDM data streams. The serial links support bidirectional synchronous interconnect up to 52Mbps over xDSL, T1/E1/J1, T3/E3, V.35/Optical, OC-1/EC-1, or SONET/SDH Tributary.

The device performs store-and-forward of packets with full wire-speed transport capability. The built-in Committed Information Rate (CIR) controllers provide fractional bandwidth allocation up to the line rate in increments of 512kbps. The DS33Z44 can operate with an inexpensive external processor, EEPROM or in a stand-alone hardware mode.
