By 90KB I assume you mean ~700 Kbps download, and 18KB is ~128Kbps 
upload.  You have ADSL.  You can read more about it here:

The entire line is bandwidth throttled.  It's not port specific.  If 
you need more upload bandwidth (for what ever reason), most service 
providers have different package options (that increase in price with 
increased bandwidth capability).  We used to pay ~$600/month for a T1, 
plus we needed to have our own routing equipment on both our end and 
the telco's end.  Now we get a commercial 2 Mbps cable connection for 
less than $200 per month, and all we need is a cable modem.  I've never 
been fond of DSL because of the high overhead it puts on routers, but 
it's infinitely more popular than high speed cable connections because 
phone lines cover a greater service area than cable service does.
