Betreff: Why TDM time slot time duration is 577us ??


Hi All, 

I wish I am posting this query to the right mailing list. If not please
let me know the correct list for this query.

I understand the basics of GSM and wireless in general. 

I have a very basic question. Why did the time slot value considered to
be 577us ?

I searches Google for some useful doc, which clarifies the reason behind
selection of time slot ?


Thanks, 
Nataraju A B
