I don't think that HSSI was designed as a point solution
until ATM came along. Couching your answers in the context
of an ATM solution is presumption, or so it appears to me.
Are you talking about point-to-point ATM or just point-to-point applications
My wild-assed guess would be that about 45% of HSSI boards are running
point-to-point HDLC or PPP and 45% are running Frame, with the rest SMDS
and ATM and god knows what else.
