Hi, our office has about 20 Macs and PCs total. We connect to a
1.5mbps T1 line through a Cisco IAD2431. This Cisco IAD connects to
unmanaged switches and these switches connect to the PCs and Macs. We
have no routers and rely on the Cisco IAD to serve IP addresses.
Right now whenever any PCs or Macs FTP or download something big, it
will completely hog the T1 bandwidth. Is there any switches I can buy
that can share the bandwidth of the T1?

Thanks
