Depends quite a bit. With customers using ISDN routers a 1 B channel
connection will have ping times just as good as above...i.e.
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 44.0/44.8/45.8 ms
Customers using ISDN "modems" end up with about 2x the latency.
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 70.7/79.8/104.7 ms
This is with a PM2ei at my end and linux ping (56 data bytes, 64 total
bytes).
