DP83261 BMAC

TM Device

(FDDI Media Access Controller)

General Description

The DP83261 BMAC device implements the Media Access

Control (MAC) protocol for operation in an FDDI token ring

The BMAC device provides a flexible interface to the

BSI-2TM device The BMAC device offers the capabilities

described in the ANSI X3T95 MAC Standard and several

functional enhancements allowed by the Standard

The BMAC device transmits receives repeats and strips

tokens and frames It uses a full duplex architecture that

allows diagnostic transmission and self testing for error iso-

lation The duplex architecture also allows full duplex data

service on point-to-point connections Management soft-

ware is also aided by an array of on chip statistical counters

and the ability to internally generate Claim and Beacon

frames without program intervention A multi-frame stream-

ing interface is provided to the system interface device

Features

Y

Full duplex operation with through parity

Supports all FDDI ring scheduling classes (asynchro-

nous synchronous restricted asynchronous and

immediate)

Y

Supports individual group short long and external

addressing

Y

Generates Beacon Claim and Void frames without

intervention

Y

Provides extensive ring and station statistics

Y

Provides extensions for MAC level bridging

Y

Provides separate management interface

Y

Uses low power microCMOS
