Jim,
  Does the cisco PPP implementation put raw PPP packets out onto the T-1? I
believe (and Bill Melohn can correct me if I'm mistaken) that the Sun PPP
implementation puts HDLC framing around the PPP packets. Bill - can you tell
me if this is done for both the T1/RS449 and 56KB/RS232 Sun synchronous
interfaces? The fact that things work using 56KB/RS232 but not with T1/RS449
implies that the encapsulations may be different.

	Thanks,
	--Vince
