DS33Z11

Ethernet Mapper


Please check latest availability status for a specific part variant.

Description

The DS33Z11 extends a 10/100 Ethernet LAN segment by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over a PDH/TDM data stream. The serial link supports 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) controller provides fractional bandwidth allocation up to the line rate in increments of 512kbps. The DS33Z11 can operate with an inexpensive external processor, EEPROM or in a stand-alone hardware mode.
