I don't think this makes much sense. 99% of the time, the choke point is the
upstream connection, not the local network.
Also, a switch gives you an ethernet segment, not a network.

tHE IDEA is that the segment(s) can be given priority. The QOS control
is required to keep the sound good, even if your neighbor is doing a
large file transfer. |

following conditions:
1. My ISP is Southbell, I am suscribed to their DSL which uses PPPoE
2, I am using a Westell C90 modem configured in the "briged Internet" mode.
3. My Router is Linksys WRT54GS
4. My ATA is a brand new SPA-2002
For three days now I have been working with my VOIP provider technicians
trying to get the system to work. They have supplied all the information
that is normally required to connect to their server but they have finally
admitted that they are not familiar with the SPA-2002, Up to date, we have
been unable to register the ATA with their server. The end result is I have
reached a dead end.
Here's what Sipura has to say (quote):
"...The adapter does not have a pppoe option for connection, therefore the
adapter does not connect to the internet. You can use the router to ensure
that the adapter connects to the internet. But you need to open the ports
mentioned in my previous e-mail. Use this for reference: "
"If you have a firewall, make sure you are not blocking the UDP PORT
5060,5061 and port for UDP packets in the range of 16384-16482.
You will also need to disable "SPI" if there is such function in your
firewall. Depending on the SIP server that you are going to register to, If
it supports NAT, then you can use "Outbound Proxy" configuration of the SPA
to connect to it. Otherwise, SPA also supports STUN protocol. (see "SIP" tab
config from web GUI) Please note that STUN will not work if you have a
symmetric NAT. If you enable the debug through syslog, and set "STUN test"
to yes, SPA will print information about whether or not you have a symmetric
NAT."
Being an absulute novice in this field, it is hard for me to implement
Sipura's recommendation specially since (to me) they are kind of vague and
do not refer specifically to the Router that I'm using.
Is there someone that can give me some advise and/or guidance on this
matter considering the setup that I have? I would most certainly appreciate
it. Thanks and best regards,

Art,
Try setting the Linksys temporarily to allow a DMZ on the IP addy that
the Sipura is sitting on.
I've got the same router, but have a Cisco ATA. Just recently I had
to do some reconfiguration so the ATA and the PC wound-up with each
other's original ip addys. The PC came up no prob, but not the ATA.
Releasing the DHCP client ip in the Linksys for the ATA and getting
new still didn't let the ATA connect. It kept trying. As soon as I
setup it's IP address as a DMZ, it fired right up. When I looked at
the outbound log file in the Linksys [you need the new Aug. '05
firmware for that] , you could see that it got it's new profile--it
uses tftp to do that. Once it's up and running, you can remove the
DMZ and it'll continue working--at least mine has for 2 years. I
never had to leave DMZ on.

The router doesn't know anything about the segments created by the switch.
If your neighbor is doing a large file transfer that clogs your outbound
link, it's not going to matter whether you have a gigabit switch or an old
vacuum tube 10-base-T hub.

While technically there's merit, the conditions on the ground make it
unlikely to matter. You assume the ISP will have their act together on QoS.
At this point in time that's not looking all that good.

But by the time you bother with the expense to purchase such things and burn
the hours configuring them you'll get nowhere if the ISP doesn't have it's
act together and MOST do NOT. Think about it, using PPPoE ain't exactly
conducive to QoS integration.
And, finally, the equipment in question here doesn't even HAVE the necessary
ports to make it happen. So while you're grasping at a concept of
technically slim merit, it won't do jack-shit to help answer the actual
question. |

That's exactly why you should not have the router between the ATA and
the cable modem. The cable modem uses time slots so that your
neighbor's use does not impact your bandwidth. MY ATA does passthrough
and maintains perfect sound quality at all times. |

I must agree with you about PPPoe. I think our conclusion is that the
equipment in question is inadequate. |

And now we've come full circle. His ISP requires PPPoE and his ATA does not
support that, so he needs the router between them.

Which equipment might that be??? The Bellsouth equipment that employs PPPoE
or the Sipura ATA that does not support it???
