It's the simplest and IMO the best framing format
for IP over
a sync line,
I've used it on T1s (well, fractional T1 since DSV11 is
limited to 256 kbps),
and it comes from Cisco.
Nearly missed this bit. The DSV-11 was rated at 256kbps but
it can actually do either a tiny smidgen over (or a tiny
smidgen under) 1Mbps on a worst case HDLC sequence,
essentially forever.
There was no supported service around that speed (I think
the UK Megastream was 1.024Mbps) so it was sold as
256kbps.
Feel free to overclock it - it should handle it
just fine!
