OK, this means: "I can't tell anything useful as a comparison between the 2, due to the conditions of my use." I understand that now. I thought you were saying there were documented or data-supported PPP diferences between the 2. -----Original Message----- From: owner-usr-tc@lists.xmission.com [mailto:owner-usr-tc@lists.xmission.com]On Behalf Of Aaron Nabil Sent: Sunday, October 17, 1999 7:56 PM To: usr-tc@lists.xmission.com Subject: Re: (usr-tc) 3com V90 Problems Jason A.

So, if I understand you correctly: Your experience says Ascend is just a better web browsing customer Access Server.
I didn't say that.
And, you can't really get a good data spread due to the local line issues being a tad different.
I said that I couldn't draw statically valid conclusions because I couldn't get useful data on connection quality from the Ascends, that our customers had already self-selected between Ascends and 3coms based on their own subjective interpretations of which one "worked better", and that they were on different LECs. As for the local lines being a "tad" different, they are much, much more than a "tad" different.
I wonder, why would the PPP be slower on the 3COM?
Is PPP slower on your 3com chassis? PPP is faster on my 3com than my maxen.
Any ideas 3COM guys?

Aaron-
Since you own both, and seem to be in the upper percentile of technically savy telecom people on this list, have YOU personally been able to gather any significant data showing that the Ascend offers a greater percentage
of
your customers a "better" connection than on the Hiper?
Unfortunatly in our network we have a number of problems that prevent us from comparing the two with any statistical rigor. First is the lack of (or I don't know how to get at them) the same connection quality indicators on the Maxes that we have on the USR's (block error rate, retrains, etc). Second is that our Maxes are on phone numbers that we have allowed our customers to self-select in using. Most are probably Macs, people with rockwell modems, and we've our CLEC has has some inter-office trunking issues that cause people to use the Maxes (they are still on the ILEC).
We do have some maxes on our CLEC, it might be fun sometime to set up a peecee to continuously make test calls to the USR's and Maxes, record the results (by dumping the modem registers) and compare the two. I wonder if anyone has a program to do this?
(By better, it may even mean a "subjective" quality of the connection, where the connect speed to both NAS's is the same, but the connection throughput is better, or just "seems and feels" faster to the end user)
The few tests we've made have the 3com's handily beating the Ascends in throughput (FTP of a random-data file) for the same current connection rate. But for some reason the 3com's have some problems in MPP performance that makes the Ascends faster, the last time we tested (at least 6 months ago).
