com GENERAL 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.
FEATURES 10/100 IEEE 802.
3 Ethernet MAC (MII and RMII) Half/Full Duplex with Automatic Flow Control Layer 1 Inverse Multiplexing Over Four T1/E1/J1 Lines Through the Integrated Framers and LIUs Supports Up to 7.
