The 'test' command expects to connect from one channel to another channel
on the same box. On a Max you can do it if there are at least two channels
available. On a Pipeline, of course, this means that there must be no
connections active before you do it. Basically, you are supposed to dial
your own phone number.

Having said this, the 'test' command remains a useful tool even if you
don't dial your own phone number, but you have to bear in mind that messages
like 'error: wrong phone number' and 'can't handshake' probably mean the
call successfully connected but the Ascend didn't see the loopback it
expected. Only 'call failed' usually means the call really failed.

After having done 'test', you should do a 'show isdn' (like you did) to
see what happened to that call. You can see that it cleared with cause
16 (normal clearing), which is further evidence that the channel was able
the place an outgoing call.

The default for the 'test' command is to place a 56k call. You can append
"data-svc=xxx" to the test command line to use a different data service.
You can use any of the values that are valid options to the "Data Svc"
parameter in the menus (i.e. 64k, voice, modem, 56k, etc...):

test 1234567890 data-svc=64k
