3GPP TSG-T WG2#3
Yokohama, Japan, 19-21 April 1999	TSGT2#3(99)384

Agenda Item:	Work Item  DTR/TSGT-02TI_P_U

Source:	Nokia Mobile Phones Ltd

Title:	Proposal for Document Structure of the External Interface Report

Document for:	SWG2 / Terminal Interfaces

___________________________________________________________________________

Nokia Mobile Phones would like to propose the following changes to the document TSGT2#2(99)056 sections 1-3 and 5 as the baseline document to Work Item  DTR/TSGT-02TI_P_U as described on page 20 of document TSGT2#2(99)144:

1. Name: 

Report on optional physical interface examples for 3GPP mobile phones.

2. The Table of Contents:

1	Scope

The following text to be added:

The interfaces and their functions specified in this report are only examples, and any manufacturers or operator can adopt these or any other for each kind of phone at will. Phones with no external interfaces are allowed.

2	Normative References

Following changes:

References 2-8 to be removed.
References to Bluetooth specifications are to be added.
References to IEEE1394 standard are to be added.
Reference to EIA-232 standard are to be added.

3	Abbreviations

4	Physical Interface

The following text to be added:

Three interface examples are discussed:

•	Radio frequency  interface using Bluetooth documents
•	Infrared light interface using IrDA documents
•	Wired interface using
•	USB Documents
•	IEEE1394 Documents
•	EIA-232 Documents

4.1	Radio Frequency Interface using Bluetooth
4.1.1	Configuration
4.1.2	Physical Layer Conditions
4.1.3	Services over Bluetooth

(References to the application related documents of Bluetooth should be reviewed briefly, there is no need to repeat the standards here)

4.2		Infrared Light Interface using IrDA
4.2.1		Configuration
4.2.1.1	Physical Layer Conditions
4.2.1.2	Protocol layer Conditions
4.2.2		Services over IrDA Interface

(References to the application related documents of IrDA should be reviewed briefly, there is no need to repeat the standards here)

4.3	Examples of Wired Interfaces

Wired interfaces have large connectors, which usually are too voluminous for 3GPP mobile phones. The recommended configuration for achieving mechanical compatibility with the standard connectors is to use an adapter cable with a proprietary connector at the terminal end and a standard connector at the other end as depicted in picture xx.

	
	Picture xx. Example of Adapter Cable Use

For the Proprietary Connector in picture xx,  any connector with any combination of signals and signal placements in the connector are allowed.

4.3.1		USB Interface	
4.3.1.1	Configuration	
4.3.1.2	Logical Interface	
4.3.1.3 	Service over USB Interface

(References to the application related documents of USB should be reviewed briefly, there is no need to repeat the standards here)

4.3.2		IEEE1394 Interface	
4.3.2.1 	Configuration	
4.3.2.2 	Physical Layer Conditions	
4.3.2.3	Services over IEEE1394

(References to the application related documents of IEEE1394 should be reviewed briefly, there is no need to repeat the standards here)

4.3.3		EIA-232 Interface	
4.3.3.1 	Configuration	
4.3.3.2 	Physical Layer Conditions	
4.3.3.3	Services over EIA-232	

(References to the application related should be reviewed briefly, there is no need to repeat any standards here)
