10 HiperDSP's - hardware version .49 & .53, software version 3.1.7 2 HiperArc - hardware version 21, 128 meg ram, 16 meg flash, software version 5.2.102 1 HiperNMC - hardware version 5, 16 meg ram, 16 meg flash, software version 8.2.7 Total Control Manager 8.2.6 Integrated fan chassis Dual 70 amp power supplies This is essentially TCS 4.3 code. We have asked 3Com for the 4.5 beta which provides the V.92 functionality. Our contract is with Source Technologies which like I said have been very good to deal with. The new TCM is very fast, or that may be the HiperNMC. All the software installed without any problems at all. A number of the things we were told to change in the configuration such as the carrier detect delay have already been set in the defaults. The only thing I have not yet gotten to work is the redundant HiperArc configuration, but I am waiting on info from SourceTech to set that up. I haven't messed with the new router configuration software as I do it by command line, but there is a new release of it as well. There is no update to the quad code, but that doesn't matter as dropping the quads has apparently resolved some of our random connection problems. We are running the DSP's with both channelized T's and PRI's at this time.

It's the HiperNMC making TCM fast, definitely. We've got a mix of 486 and P133 NMC's out there and the difference is VERY noticable. We're thinking about upgrading using the new NMC trade-in promo mentioned here. (Plus it takes care of the v.92 thing -- or would if I could get the code, I can't even get TCS 4.3 right now...)

You mention a change in the carrier detect delay with the new code. The default is 7 for carrier detect delay and 6 for the carrier loss detect delay. Is that what you have? After looking through the disconnect stats, we have more "no carrier" disconnect reasons than I'm comfortable with. I'm wondering if there is a better number here. thanks, Randy

I have noticed the high number of no carrier reasons as well, but the measure that works for me is that our phones just aren't ringing with connect problems. Usage is up, new customers get on immediately, and old ones aren't calling and complaining. I've wondered if the no carrier reasons come from other things such as autodialers for telemarketers and the like.

I was thinking some OS's just killed the modems to end a ppp session, but not sure.
From 3com knowledgebase:
Explanation of carrier Loss(4): The modem detected a loss of the remote modem's carrier and waited the time duration specified in Register S10. This register's default is 0.7 seconds. For higher speed modulations, carrier loss detection is disabled when other recovery mechanisms are used (such as retraining). It is rare to see this disconnect or fail to connect reason because other reasons are usually used or are detected sooner. --- So maybe this number is irrelevant if we're using retraining (x2/v90), but may be relevant on older slower modems? You still have yours set to 7? I seem to recall setting old quads to 70 at one point. Randy

With out coming off as a junior idiot here, I need to ask a question about PRI. In our town they said they would never get PRI so I never read most of the posts here concerning them. We used CT1's and I know (basically) how they work. Now they have PRI and I am converting -- Ok, so enough rationalizations for asking stupid questions. Here's the question: Do I lose 1 channel on every span for the b-channel or does just one of the cards in the rack need to lose the channel? Qwest says that they support 11 spans with one b-channel, so it made me curious on the 3com equipment. Anyone have a quick run through on setting these up or just a link I can read somewhere? These are DSP's by the way. Thanks, Terry Kennedy

DSP, with anything other than an ancient vintage of software will support NFAS. NFAS = Non-Facility Associated Signalling NFAS is the setup whereby one D channel (note: not B channel) carries the call signalling for more than on PRI span. Each B channel carries an individual call, a D channel carries the call control information for the B channels on the span (or multiple spans in the case of NFAS). We don't use NFAS here because of the hassle in coordinating which spans have the D channels (and backup D channels) with the telco. The extra B channels that you get from running NFAS aren't worth the hassle as far as I'm concerned. :) -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456

We don't use NFAS here because of the hassle in coordinating which spans have the D channels (and backup D channels) with the telco. The extra B channels that you get from running NFAS aren't worth the hassle as far as I'm concerned. :)
Ditto. More wacky 3Com code to troubleshoot, more coordination with the telco on something they may or may not understand, and less reliability. Charles

No, not really. The span with the backup D channel takes over. We did lots of (inadvertant) testing, and it works very well if setup right in the TC and the Telco. ----Steve Stephen Amadei Dandy.NET! CTO Atlantic City, NJ

It also makes it more difficult to quiesce PRI to do any kind of circuit maintenance. Definately not worth the hassle dealing with the phone company (unless of course you are the phone company).
There is an option called NFAS, using this you can use one B channel for several cards. 3Com supports one B for 14 spans on the DSP, however you should consider having two B support the entire chassis one main and the other backup. -V ----- Original Message ----- From: "Terry Kennedy" <terry@olypen.com> To: <usr-tc@lists.xmission.com> Sent: Wednesday, June 05, 2002 6:51 PM Subject: [USR-TC] PRI and b channels
With out coming off as a junior idiot here, I need to ask a question about PRI. In our town they said they would never get PRI so I never read most of the posts here concerning them. We used CT1's and I know (basically) how they work. Now they have PRI and I am converting -- Ok, so enough rationalizations for asking stupid questions.
Here's the question: Do I lose 1 channel on every span for the b-channel or does just one of the cards in the rack need to lose the channel?
Qwest says that they support 11 spans with one b-channel, so it made me curious on the 3com equipment.
Anyone have a quick run through on setting these up or just a link I can read somewhere?
These are DSP's by the way.
Thanks, Terry Kennedy

With a PRI you will lose 1 channel. You will have 23B channels which users can connect to a 1 D channel which will be used for signaling, etc. Qwest is probably talking about NFAS...Non-facilitated Associated signaling, or something to that affect. In essence what you do with NFAS is have a span that is your primary D channel, and another one that is your backup and then the rest of the spans can be "pri" but have 24 B channels. Word of caution...NFAS becomes more complicated the more spans that are in the NFAS group. Some telcos say they can do it but really don't know what they're doing, hence causing problems down the road. -----Original Message----- From: usr-tc-admin@mailman.xmission.com [mailto:usr-tc-admin@mailman.xmission.com]On Behalf Of Terry Kennedy Sent: Wednesday, June 05, 2002 7:51 PM To: usr-tc@lists.xmission.com Subject: [USR-TC] PRI and b channels With out coming off as a junior idiot here, I need to ask a question about PRI.

Ok guys thanks for the heads up. It's another "well it should work but in the interest of stability stay away..." Ok I get it. So set the span line setting from robbed bit to message oriented and away I go....

Can you insert a new PRI card into a TC unit with it still running? Is the original Total Control unit now called the Total Control 1000, or is that a new and improved model? I've got the Total Control with the HiperARC and HiperDSP cards.
In my experience it is better to turn off the unit when installing and de-installing the older quad bundle components. No problem with HOTSWAP on hiper generation of cards would advise you to turn it off. At 11:44 AM 6/20/2002 -0600, you wrote:

Yes you can.. that's how it's designed. TC-1000 is a newer version of the Total Control but there's no difference that I see. There is also a TC-2000 that's different - Higher end stuff.
