Firstly I suggest reading and/or subscribing to the Portslave mailing list.


Cyclades people are on the list (but they keep a very low profile).  
Portslave is used on much Cyclades hardware including in the dedicated 
hardware boxes they sell.  There's many people there who can discuss the 
down-stream use of Cyclades products (E1 == 30 analog modems), and some 
people who can discuss the upstream use (E1 == 2Mb of net access).

That is what you expect.  Sending a few megabits of data around isn't that 
difficult really.

Yes, Sangoma and Cyclades are among the good companies that release the 
source to all their drivers making it easier for us.

I installed an Emerging Technologies card for one of my clients (binary-only 
kernel module) and have really regretted it.  I wish the client had enough 
budget to allow them to throw away that ET junk and get a Sangoma.

Why do you expect a CD-ROM to be more reliable than a hard drive?

Why not just use software RAID on two hard drives?

Or if you want to be really advanced get a flash disk...

By PC pricing standards Cyclades products are expensive.  They have a smaller 
market and they are server products.

Compare them to Cisco products etc and they seem quite cheap!

There's lots of other issues when comparing a Cisco to a machine with a 
Cyclades card.  With a PC router you could easily put a web server to show 
stats on the router (instead of monitoring it by SNMP and doing the stats 
elsewhere).  With a PC you can easily expand it etc.  With a PC a buffer 
overflow doesn't necessarily mean the entire machine is dead (unlike Cisco 

Also PCs have lots of spare CPU power which is REALLY useful for running 
tcpdump type programs.
