(usr-tc) Compression?
Hi... At work we have a 3com/USR Total Control NETserver.. fully populated with 12 quad cards (48 modems). I am using RADIUS for authentication and all, but I'm wondering if there's a way to know or check to see if it supports STAC compression on the ISDN at all or not. If so I'd really like to know howto turn it on. For the curious, we are using Cistron radiusd, and which I don't know how to make it use/recognize the STAC compression if it's available. Also, how do you turn on / check for regular tcp header compression? The reason why I ask is at home I have my Cisco 1004 dialing in (at 128kbps) and when I tell it to use compression.. it just rejects it on the NETserver from what my debugging tells me.
From what other people have told me, NETserver's aren't the greatest for compression, but considering I'd probably be the only one using it, I'd rather attempt to use it.
If anyone is of help, please write back.. Thanks. Scott - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

set ccp on This is default, so it should be on already.

Here's the kicker...the NETServer (and I believe the Arc does this as well) will only negotiate CCP if it believes it has enough CPU horsepower to be able to do it without adverse affects. Because the thing only has a 486 processor, if it has a lot of calls on it, it will reject CCP in order to conserve the processor for normal packet processing. This is a "Good Thing". -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

newer arc's a using p-5 based chips... I'n not sure of the part #'s. Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Wed, 2 Feb 2000, Jeff Mcadams wrote:

NETServers all used 486's (though the clock speed varied some over time from 33Mhz to 100Mhz...I think really early ones might even have been 25Mhz). The Arc's use a PowerPC 603 chip...which certainly gives them extra oomph to handle more CCP. I believe you may be thinking of the HiPer NMC, which is a Pentium based board. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

you are correct! don't know why i say ARC but think nmc. Doesn't matter. 3Com is on it way out... to much trouble, not enough support and way to many headaches. Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Wed, 2 Feb 2000, Jeff Mcadams wrote:

I hate to say it since there are lots of negative comments lately on the 3 Com Total Controls. We use the Hiper versions and have no problems, we love the things they work great and we have them at various pops handling on average 8,000 log-ins a day. Our call failure rate is 4% and we have these on GTE switches (GDT5) and Ameritech switches (5ESS). We have occasional problems with modem pairs failing but not very often. Overall since 3 Com has released better Hiper DSP code just about any modem works on them and connect speeds overall are very good. We have used other types of equipment from other manufacturers and they are no better that we have seen. On 3 Com support it sucks bad if you do not have a full 24x7 contract, we do have now and I get right through everytime and they are quick to help or ship out a replacement part, so I cannot complain. I of course have to pay for the contract which I really did not want to do before I finally got one, but now that I have it I will always renew it. When you look at the cost of one verses keeping your customers happy and your equipment running properly it is a small price to pay. These are of course my personal feelings but I have been on both ends and I am much less stressed now with a contract believe me. Just my 2 cents worth. Thank you, Clint R.

I would have to concurr with this in it's entirety. We've been using the HiPer TC for about 2 years now, and initially, getting in touch with a support engineer took a great deal of tooth pulling. In the last year or so, I've never observed the wait queue to be more than 2 deep, and furthermore, I've had engineers call ME to follow up on calls. The only problem I have now (and it's admittedly minor) is that we're located 15 minutes from their parts depot, but they won't hold an item for "will-call", it can only be shipped. So, we wait for an overnight delivery when we could have sent someone to pick it up. "Clint R. Sparks" wrote:
