Finally I fixed the problem with the "slow" SDSL link and thought maybe you'd be interested in throughput figures. The setup: 2x DSLpipes (DSL-HS-2.3), symmetric 2.3 Mbps, back-to-back with a straight 1:1 cable as the "WAN", one as COE, one as CPE. Nailed connection, either PPP or FR, bridging only. Transmitting a 4 Meg binary file via ftp, 4K chunks (and 64 K): KBps PPP VJC Stac-9 98 PPP Stac-9 95 PPP VJC 259 PPP 258 (264) FR 262 (268) So it seems the old ISDN hardware of the P50 is sweating away at the much higher bitrate. For this scenario FR does not offer visible advantages regarding throughput. I will test the effect of routing over bridging when I deploy the pipes, and will put it on this list. Thanks to all who answered so quickly, you all were right Dan, Scott and Peter!
