Is PTT ISDN the way ?
ISDN works
- physicists in Batavia work at home happily with FNAL calling back on commercial ISDN, 64k upgraded to 128k automatically when usage > 48Kb/sec (seldom unless heavy web graphics). The lab also provides the networking equipment at home.
ISDN exists
- just on Italian Telecom Phone Book, can have it everywhere
ISDN is end-to-end
- gurantees bandwidth all the way from one room in Italy to CDF control room LAN, no matter what.
ISDN is (relatively) cheap
- 64kb/sec = 55 Klit/hr (27 Euro)
- 5hr of remote work cost like 1 day in Fermilab + save the flight money and time (and jet-lag)
