Mainly because we haven't fielded the PM-4 yet and that is the product for this class... I had some issues with their data table and emailed this to the author: ---cut--- I do some of the competitive analysis for engineering here at Livingston, so a few things caught my eye in the data table. I hope you don't mind my sending this. I have some questions about the data. You say the MAX TNT can have 672 modems per chassis. This is not true. Each chassis, or shelf, holds 288 modems. It can terminate 672 DS0s, but not modems. For 672 modems you need a stack of 3 'shelves' or chassis wired together. I'm also not sure the T3 card has been fielded at this time, but I don't believe so. Also, the TNT is claimed to support X.25 - I didn't see that listed. You list 672 modems for the Bay Networks MSX 5000. Can you confirm that? The materials I have from them indicate you can use up to 12 remote access modules, and the 5399 is 2 lines, 48 modems for T1. Or 576 modems. They have 62 modems per for E1, or 744 modems per chassis. (Though only 60 channels on 2 E1 ports, so really 720 usable modems). This is from the 5399 data sheet, also from conversations with people over there (I used to be with Xylo). For protocols on the 5000 MSX, as with the TNT a variety of modules are available. Ether, Fast Ether, FDDI, Token Ring, ATM, PRI, Channellized T1, and Analog/Async. It just seemed fair to mention these as a variety of media are listed for the TNT. On the 3Com Hi-Per access I think the '450' modems is misleading since T1 figures are used for the other products. Under T1 the Hi-Per can hold 336 modems. Or 14 cards at 24 each. With E1 they go to 420 modems, or 14 x 30. This is directly from the data sheet avaialble from 3Com. Can you confirm X.25? I know they have X.75 support. All of their write ups list or show 14 modem cards with 2 HiPer ARCs (Access Router Cards). Was the 450 figure using one ARC and 15 cards? With that I could see 450 on E1 or 360 on T1. But I wasn't aware that the unit supported that many. If you can confirm that I'd appreciate it. I'm curious - why distinguish 'Ascend RADIUS' as special? It is just another implementation of RADIUS. Ascend AAA really isn't special. ---cut--- -MZ -- Livingston Enterprises - Chair, Department of Interstitial Affairs Phone: 800-458-9966 510-737-2100 FAX: 510-737-2110 megazone@livingston.com For support requests: support@livingston.com <<A HREF="http://www.livingston.com/">http://www.livingston.com/</A>> Snail mail: 4464 Willow Road, Pleasanton, CA 94588 ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg11537.html">(ASCEND) TNT and ISDN</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg11530.html">RE: (ASCEND) P50 Beta 6.0 vendor MIB bugs</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg11535.html">(ASCEND) Data Communications Remote Access Servers comparison</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg11537.html">(ASCEND) TNT and ISDN</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="maillist.html#11536"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd271.html#11536"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
