have an ASN with 8 T1s that send voice/data to remote BCMs via the BCM WAN port. All voice is prioritized within the ASN, while data takes a back seat.

However, when a large download is being done across the WAN link, all other data and voice communications ceases. Example, I was downloading a large patch for the BCM at one of the remote sites then everyone elses data stopped. Ping results came back with "request timed out", even from the PC still downloading the patch. I was achieving about 158Kbps on the download, which was still going on. When I cancelled the download all communications came back up...

I thought it may be something with the switches on site, but went to another remote site with different switches and performed the same download, and the same result happened.

Any ideas??


Thanks in advance!

Hi,

Is there any proxy server in your LAN??

Couldn't really tell you. We, the company I work for, only handle their voice and the customer has their own IT department. They may have one, what type of proxy would I look for?

Hi,

You should look for a ISA or Squid Proxy Server. It seems that the data traffic is not being controled properly. There is connectivity as i can see... Maybe the traffic is being droped due a not good QOS config on the ASN. Lets check it too, ok?

There is no proxy server on site. On the asn we have configured dsqms through telnet on each interface that the point to point t-1's are connected to and have 2 queues. queue 1 is priority with a dscp of 46 to give the nortel voice priority. Queue 2 is weighted and has dscp of 0 for everything else. Queue 2 is 100% weighted, but is only weighted queue in each connection.
