the E1 line is composed of 30 lines of data (30x64kbps) 1 for signaling (which you will pay for) and one for synchronization (which you will not pay for).
now, you will pay 31*20k= 620k to get the channels. and 31*5=155k for ~2mbps download. now here comes the pain. 2 mbps for upload will cost you (31*49*60*24*365/12) that's 2772k. add the VAT and you get 3900k. add the 600k maintenance and you get the exact (estez ana) 3000$ i was talking about.
