Frame-Relay T1 to site 150 miles away:

5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 11.662/16.609/25.846 ms

Frame-Relay 56k to site a few miles away (but it has to go about 10 miles
to and from the switch):

5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 49.046/49.448/49.779 ms

How does ISDN measure up to this?
