This doesn't necessarily pertain to FreeBSD(although it will depending
on what kind of answers I receive) but it's interesting nonetheless. I
work for an ISP and one of the services we offer is dial-up internet.
Our 3COM hardware( the CSU/DSUs and the DSP cards) is on its last legs
and requires frequent reboots. I've noticed that you can purcahse T1
cards that support up to 4 T1 lines and contain the CSU/DSUs on them for
a few hundred dollars. The problem is that you then have to get DSPs
for them and that raises the cost to around $5000. For $5000 we can get
more shitty 3COM hardware than we'd know what to do with, so thats not a
good solution. I was thinking, why can't the DSPs be emulated? Does
anybody know of any software that will emulate some number of DSPs(92
would be the max for 4 T1 lines) and interface them with a CSU/DSU? If
no software exists what brand of hardware do you recommend for this type
of application. There seems to be only about 6 companies that make this
stuff and none of them seem that great. I appreciate any feedback I
recieve.
Thanks,
Ryan
