Kevin - many thanks
Roger - I guess this could be sent to SMG1, with a copy to S1 for
information.

Dear Kevin,

>Following a brief private discussion with Alan Cox it seems that it would
be useful to have a private meeting among a few of us. The TSG meetings in 
Yokohama seem an ideal opportunity for this. It is important for the 
technical people to understand the proposed solutions on two levels: the 
service level and the technical level - this is in accordance with the 
structure of our working teams in 3GPP. 
Please accept my apologies if my earlier approach appeared difficult. It is
not my intention to block or delay any proposals, just to enhance 
understanding and avoid duplication of effort. 
The TSG-T2 meeting in Yokohama is taking place at the Fuji View Hotel,
19-21 April. When might be an appropriate time for an informal meeting? 
NTT DoCoMo agrees with you that we will have an informal meeting for 
resolving issues on non transparent T.30-based fax, during the TSG-T2 
meeting in Yokohama. 
NTT DoCoMo could do, if appropriate, the demonstration on T.30 based 
mobile fax machines using PDC, on April 20 or 21, at Yokohama. 
The service requirement from NTT DoCoMo (SMG1 DCC 128) is attached with 
this e-mail. 
Its summary is as follows. 
In Japan, real time non-transparent FAX service is provided based 
on T.30 protocol. Portable FAX products (50,000~60,000yen : US$400~500) 
are available for mobile users. Until now, 32,000 units were sold in 
Japan and it is increasing constantly. This fact has shown that real time 
non-transparent FAX service gained the wide market acceptance. 
As the same view as the operators in Europe, NTT DoCoMo plans to provide 
its users with the same and better services offered by UMTS/IMT2000 than 
in the second generation mobile systems. 
From the operator point of view, it is important to keep continue providing 
real time non-transparent FAX service. Since UMTS is the evolution of 
GSM, this service will be an enhanced based on GSM specifications. 
To this end, we believe that non-transparent FAX service should be 
retained in the GSM specifications. This service should be considered as 
an option left to the operators. 
I hope this helps you. 
Best regards, 
Norihiro Ishikawa 

Best Regards, 
Kevin Holley
