A wide variety of topics have been brought up lately. What are the lists users thoughts of other remote access products compared to 3com- Total Control? It seems the 3com is widely used products among the ISP forum. Any comments are appreciated.

Heres the ones ive personally used Cisco AS5248 The good - excellent support excellent feature set 'no one ever got fired for buying cisco' The bad - IOS was never really designed for handling dialups and it shows Severely underpowered CPU (68030) 'merely adequate' modem DSP code Lucent PM3 The good - good feature set good tech support The bad - Somewhat underpowered cpu 'fair to good' modem DSP code ComOS can be flaky (spontaneous reboots etc) 3com Hiper The good - good feature set blazingly fast CPU and architecture (overengineered? :) excellent modem code The bad - terrible tech support Ascend Max The good - good to great modem code good feature set, minor annoyances on some features (eg DOVBS) The bad - Somewhat underpowered cpu - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

The 5248 is no longer sold by Cisco. It's still officially supported, as Cisco doesn't tend to EOL things for several years after end of sale. The AS3648 and AS5300 both are replacements for the AS5248. The AS5300 I have uses about 3% CPU to server 30 or 40 calls.

We are considering moving about 30 PRIs from TCs and PM3s to AS5300s. We have one Crisco AS5300 up with 8 PRIs and use it mostly for ISDN and are quite happy (Crisco tech support is excellent!). My question is how do you find the modem performance on the newer Crisco AS5300 relative to the TC/HPSP and PM3 DSPs? Thanks -Dan Brian Elfert wrote:

We have quad modems rather than Hiper DSPs. Customers pretty much got the same or better connections on the AS5300. We ran our PM3 with K56Flex code, and no V.90. The problems we're seeing are some K56Flex only modems only connect at V.34 to the Cisco. Cisco seems to have concentrated a lot more on V.90 than K56Flex, which is only natural.

Yes AS53xx seems to have more adequate CPU, MIPS R4xxx right? But 3com still has far more cpu power As far as feature sets go cisco has by far the most complete The modem code still doesnt seem to be anywhere near 3com's though -Dan - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I think 3com is the best compromise right now. They really don't have many issues to resolve as far as I am concerned. If they cleaned up their support contract situation, ospf, and continue to work on their modem code, I think they would be the definite #1. The thing is, this industry is fierce. 3Com is adding and adding features because you have to keep doing that, so you don't fall behind what the competition is doing. Everyone is adding VoIP, QoS, etc. 3Com can't stop everything and just work on core things like OSPF/modem code, they have to keep advancing or fall behind. Corporate and Carriers want to see that stuff like that is in the pipeline etc. Their isn't an unlimited supply of clue out there either, at any price, to work on things like developing VoIP etc on a chassis. Its a tough deal, I can sympathize. All we can hope is that the engineers there are paid well and work nonstop. Unfortunatly reliability isn't what drives most these companies, its marketing and features and getting the next version out just to say they have VoIP *today* etc, and who cares if its all working yet.

Yes they can. Who in this list is seriously doing VOIP? It sucks. In a few years it will work, but for now leave it in the beta testers hands. Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Fri, 4 Feb 2000, Brian wrote:

I understand Cisco uses VOIP to route calls overseas for 24x7 support. Cisco only uses USA call centers during the day in the US. Overnight calls are sent to Australia amongst other places.

They've been doing this longer than VOIP existed as a widespread concept, so unless they switched to a VOIP solution recently, its done in a different manner.

Cisco really looks like they are clued in on VoIP, I noticed Cisco is now pushing to deliver powered Ethernet ports so you can plug Ethernet based Cisco telephones into their Ethernet switches and they will require no external power whatsoever. If there is a VoIP revolution, Cisco is in place to reap the rewards for having the products people need to execute the revolution. I see corporations with just one network, and it's going to be based on Ethernet, providing switched voice, data and video all over IP. Corporations all over are asking for this kind of stuff. I imagine 3Com is under pressure to keep up with Cisco, which has quite a few VoIP solutions built into their routers and switches. 3Com just doesn't have the resources Cisco has amassed over the past few years. -Ron GLISnet, Inc. +1 810/939.9885 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

As one in Australia, I know that some of our calls end up in the USA. VoIP would certainly explain why those calls sound pretty ordinary. ------------------------------------------------------------------------ Bob Purdon, Ground Floor, Marine Board Building Technical Manager (Tas/Vic), 1 Franklin Wharf, Tas 7000 Southern Internet Services. +61 (3) 6234 7444 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I never said the Hiper ARC doesn't have more CPU power. I just mentioned that the current line of Cisco products has more than adequate CPU. Someone was comparing a discontinued product against the 3Com stuff.
The modem code still doesnt seem to be anywhere near 3com's though
I beg to differ. I have quad modems, and my tests showed the Cisco connects the same or better for those with V.90. Obviously, x2 only customers get screwed, but I'm keeping a Total Control rack for them. I used to think USR/3Com modem code was the best, but not any more.

My experience indicates cisco modem code is overly conservative, favoring lower connect speeds (trading off speed for stability) -Dan - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I have a crappy phone line at home (whereas the other one is connecting 50,666.. don't ask). With a rockwell V34: -quad/dsp = connect 26,400 -> so many retrains it's not useable -pm3 = 28,800 -> ditto -cisco = 31,200/24000 fast and stable So upload seems to be the problem, and only cisco is able to deal with it. I tried with Sportster56k and results are the same. Martin - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

3com Hiper The good - good feature set blazingly fast CPU and architecture (overengineered? :) excellent modem code The bad - terrible tech support
I hear tech support is good these days. "support" however, as in contracts and cost of support is another issue. Also this forum blows away ascend-users. If you own a TNT good luck getting help.
Ascend Max The good - good to great modem code good feature set, minor annoyances on some features (eg DOVBS) The bad - Somewhat underpowered cpu
majorly lame CLI on the TNT...........totally strange.
