US Patent:

61920355, Feb 20, 2001

Filed:

Jul 24, 1997

Appl. No.:

8/900204

Inventors:

Andrew Keith Boggs - Raleigh NC
Quy N. Hoang - Raleigh NC
Joe Jacobs - Chapel Hill NC
John Mark Mullen - Wake Forest NC
Challis Purrington - Raleigh NC
Laura A. Weaver - Durham NC

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 1242

US Classification:

370252

Abstract:

An intelligent multistation access unit is provided having a transmission speed detection circuit for determining the data transmission speed of an attached device attempting to gain access to a node of a multiple transmission rate digital data communications network. The intelligent multistation access unit is comprised of a speed detect circuit, which indicates the data transmission speed of the attached device, a switching circuit which directs the attached device to the speed detect circuit until switched to allow the attached device access to the network node, and a processor that controls the switching circuit and which permits the attached device access to the node depending on the data transmission speed indication.
