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
