It will handle load much better, providing you use currently-supported cards. Some of the older cards were awful and will cause you pain and suffering. From the TAOS 9.0.0 release note: Notice of discontinuance of software support Software support has been discontinued for the MAX TNT Ethernet-0 slot card (TNT-SL-E10), the Fast (100 MB) Ethernet-1 slot card (TNT-SL-E100), and the older MAX TNT Hybrid Access slot cards (TNT-SL-HA128 and TNT-SL-HA192). This means that if you have any of these cards you'll never be able to upgrade your TNT beyond 7.x. You don't want that. The 192hdlc-card you list is not robust, reliable, or even supported in TAOS 8.0. You don't want one. Then you need to look at how many concurrent ISDN sessions you'll have and use an HDLC card (or cards) with enough processors. I don't know what a 4/1ether-card's actual model number is, but I think it's a problematic card too. I haven't used the dual-slot 56-modem cards, but even if they're reliable I'd be concerned that they're using up almost all your slots. Will you need another 8-E1 card? Or a channelized DS-3 card? Are you prepared to go to a multi-shelf system to add more than one more card? I'm not aware of any issues with the 8-E1 card, but then I'm in the U.S. We haven't had any troubles with the 8-T1 card, FWIW. I'm also not sure if the 16 A power supplies are the High Output supplies, but that's what you want there. Hint: they're not cheap.
