Two cautions: when I last tried it, about a year ago, an Ascend
Pipeline 50 talking to a Combinet CB-900 PRI interface got
IL checksum errors that do not appear when both ends are Combinet
boxes.  I think it's a bug in Van-Jacobson header compression.
Also, a Pipeline 50 talking to a CB-900 reproducibly but gradually
corrupted and crashed the CB-900.  Both of these bugs could be
fixed by now; the local ISDN support folks haven't encouraged me
to find out. :-)
