Filed:

Mar 19, 2001

Appl. No.:

09/810452

Inventors:

Robert B. Sautter - Long Pond PA, US
Charles H. Braun - Carmel NY, US

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

H04Q 7/00

US Classification:

370392

Abstract:

An improved user data protocol involves a multi-addressing capability that allows a user at a source node to address a single message to many users at respective destination nodes within a communication network. The multi-address messages that are provided to the network are inserted once at the source node, and messages routed between network nodes going to the same next node travel once across each interconnecting communication channel, thereby minimizing the communication bandwidth consumed.

Appl. No.:

8/963169

International Classification:

H04L 514

US Classification:

370276

Abstract:

There is disclosed a voice/data protocol for use with half duplex digital radios. The protocol modifies the X. 21 HDLC protocol which is widely employed in the transmission of data for digital radios. The X. 21 protocol utilizes a control "C" and an indicate "I" signal. In the steady state in conventional systems, both the C and the I leads are "off". When either a DTE or DCE requires service, the units set their C lead to the "on" condition. The opposite end detects the request for service on the I lead and when communications occur, sets the C lead to the "on" condition. When both the DTE and DCE have send and detected "on" conditions on their C and I leads the circuit transfers to the data transfer state and is ready to proceed to data synchronization. In the present protocol, the C signal is defined as a push-to-talk transmit request to the radio. The I signal is defined as a radio busy.

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

H04Q 1100

US Classification:

370465

Abstract:

An improved user data protocol is well suited for both Internet radio and packeting switching networks and provides built in addressing and transport control capabilities. Basically, the user protocol consists of layers 4, 3, and 2 of the seven layer OSI/ISO model. The protocol enables communications between Data Comminations Equipment and Data Terminal Equipment and particularly is adapted to provide communications both voice and data between radios. The main feature of the IMPROVED Protocol is the ability to transmit multiple data frames in a single transmission including the transmission of a particular synch. Transmissions basically consists of the transmission of an opening flag for a first frame and a data frame for the first frame and a closing flag for the first frame followed by an opening flag for the next frame and a data frame for the next frame and a closing flag for the next frame and so on where each data frame includes an address field followed by a control field followed by an information field which is followed by a frame check sequence. The frame format can be with or without an information field with each frame includes as indicated a flag, the address field, a control field, and a frame check sequence and an ending flag with the flag being an eight digit sequence of ones and zeros. Based on the unique flag format and the ability to provide different frame sequences one can implement a multi-addressing capability.
