Subject: Live event - bandwidth Problem

Hi,
I am newbie for live broadcasting.
I have several questions.

1) In my area, there is difficult to install dedicated
line and ISDN. I know there are some products that
can aggeration serveral phone lines into one.
Does this product existed?

2)Actually, how many bandwidth does I need for
a live event which encode two multiple streams
(28.8K and 56K) for realproducer+ generally?

PK
thanks
