>From here at work, "dialing" out of a big pipline box with many lines
into it, and over to my pipeline-50 at home:

$ time ping mymachine
mymachine.qualcomm.com is alive
real        6.2

after that, round-trip pings are 42ms.

This is the setup time. In preaty much any-case, (raw/slip/mslip/ppp/mppp/
frame-relay) your total setup time is preaty much dependant on dialup-time.

in the setup of my box, I am running multilink-ppp, VJ header compression,
and (v42?) data compression. and am getting 12KB/s ftps, and more with text
files when both b'channels are up.  I think this will always beat out "raw IP"
over isdn. 

in the long run...even if you have to wait another month or three to
afford the cost of a bridge/router such as the pipeline-50 (with a built
in NT1 and ethernet out the other end),  I'd _not_ buy a simple TA. get the 
BR...
