It is rather more dense than the AS5800. It also has a lot more growth
room than the AS5800. At first I wasn't mentioning this, but since so
many people have told me other Lucent reps are talking about it, expect the
PM-4 to support multiple T3s for dialin in time. DSP die size is shrinking
across the industry, AND *at the same time* these new DSPs support multiple
modems sessions in one die!
Two Cisco reps have straight up told me the AS5800 can handle 2 T3s on
its backplane, possibly 3 - but they don't recommend it. A PM-4 could
handle 2 T3s PER SLOT - and still have excess. You might even squeeze in
3 T3s per slot, but that'd be tight - the minimum backplane per slot is
155Mbps, but there is some overhead. A slot would be able to handle an
OC-3 (also 155Mbps) I would think. The AS5800 cannot. The PM-4 also
has a slot which has a 622Mbps interface - to handle an OC-12 - find another
chassis to do that in this class.
