Hi. How do you set up several Quintum A800 to share one cable internet connection? (Note: each A800 has its own public IP address) Do you connect the A800s to a router connected to a cable internet modem or to a switch connected to the modem? Please recommend brand and model of router or switch to use. Thanks in advance.2nd October 2003 at 12:32 #25374nonameGuest
A switch will be the best option, since you eliminate the colission issues.
I do not know if you have the money to do it, but almost any Foundry switch will be perfect.
They are the Cadillac of switches, where you could assign the ammount of bandwith that you want each device to use.2nd October 2003 at 14:01 #25375Vernon R.Guest
Thanks Noname. What particular model of foundry switch do you suggest? How much is it? How is the difficulty in configuration? Would a regular switch like 3Com officeconnect or superstack do?
Thanks in advance, no name?3rd October 2003 at 12:38 #25376nonameGuest
Almost any switch will do just fine if all what you have on it are the A800.
The trouble is if you have the A800 on the same network than computers users, specially if you do not control those P.C.
If you are trying to pass calls and someone is downoloading the lates porno, the voice quality will suffer if you do not have bandwith or the delay goes up.
But if you are not bandwith poor, and the only thing on the network are the a800, any switch will do.
Calculate 15-20 kb per call to have a safety margin. If you multilply the ammount of channels times 20, and still have bandwith, you are very safe with any switch.
As long as you do not have any teenagers daughters downloading music clips on the same network……
O yeah, I read that in a book. My teens will never do that (again).3rd October 2003 at 14:53 #25377hwykingGuest
Quick question, have u worked w/sip phones before…any recommendations…!!!espically to ones that can do h323 & sip…
Thanx in advance

Nope, no experience with SIP or MGCP.
Understand that they should be better than H323 on some areas, and have a easier time behind NAT ‘s and firewalls, but I do not know anything about them.
Sorry!6th October 2003 at 16:11 #25379DaveGuest
Well, if your cable modem has no router capabilities. I suggest a linksys switch with the Quintums plugged into the switch. The Quintums would then have the outside IP addresses. If you have a network of pc’s then you would attach a router to the switch and the PC network would break off from the router. If this is the setup, bandwidth is the key to having the system work correctly.7th October 2003 at 01:48 #25380VernonRGuest
Thanks Dave. So you’re saying that a switch or a router connection with the quintums would do it. What’s the better option though – a switch or a router? Thanks in advance.

If you have no internal PC network, all you would need is a switch. It would handle the job. If you have internal pc’s on top of that, I would have a router then attached to the switch and then break your PC network off from there. At that point you could use another switch or hub to handle the PC’s in the network.9th October 2003 at 07:11 #25382VernonRGuest
Thanks a lot, Dave.

Would a microwave broadband internet connection be okay for mutiple VOIP gateways? or would a cable broadband be better? Both with symmetric download / upload, and static IPs26th October 2003 at 16:53 #25384NonameGuest
There are many “flavors” of anything. Some microwaves are excelent transport, some are not.
As a rule, you do not care how the data gets to you , as long as you have around 15 kb of bandwith per each channel in operation, and the delay will be around the 600 ms round trip or less.
That is when the channels are in operation.
I have seen plenty of services where the delay is good, the bandwith is there, but when you load the connection, the delays jumps out of the scale.27th October 2003 at 01:32 #25385VernonRGuest
Thanks NoName. I appreciate your input.

JUst curious, where did you get the cable service with multiple public IP’s? I need one of that.
