This is a bogus comparison. And we run a 386-40 BTW, not even a 486.
So they use a RISC chip - BFD.
You CANNOT compare processors on completely different architectures. For a
closer comparison a 30 port PM-2e uses one 386, a 36 port Remote Annex 4000
uses 2 486 processors. When we ran tests on both the PM has slightly better
perfomance on average.
It all depends on the HW and SW design - on our units the CPU really isn't
working hard. You could run a PM-2ei with 30 B channels going full blast
and the CPU will not be even near fully utilized. Remember, ComOS is
written to do nothing by run the comm server, and it is very tight code -
around 300K. Find another comm server or router with code that dense and
efficient. We don't need high powered, high priced hardware to run
bloated, inefficient code.
So, big deal if they have a larger processor. We could use a larger
processor too - and just waste more of it and charge you more.
The dual PRI unit will be using a 486DX2-66 I believe, which again will be
overkill. But it leaves a lot of head room for growth. We did that on the
PM-2 and it has grown up into the PM-2ei and still has elbow room to grow.
Actually, ISDN is DMA and async serial uses CPU interrupts. So it wouldn't
surprise me if the CPU is working less calls on an ISDN unit. Just off
the top of my head, nothing I've bothered to check.
