ah. that is my problem... i have tcm 3.5 and 8.? but no 4.0 i thought i was just stupid and missing something... i ordered the dual 130's to be safe. its just so confusing what you need to do what when you haven't really had to think about the total control stuff for a long time because it just keeps on working without having to touch it. i think i'm going to try dual hiper arc's with 10 hiper dsp pri cards and dual 130's. i have a non-hiper nmc card. i would like to be able to flash my hiper dsp's and upgrade my hiper arc but i only have the tcm v 3.5 and version 8 i don't really want to replace the nmc card to a hiper nmc if i don't have to. how big is the demand for v.92? we have only had a few calls for it. i am more interested in maintaining the quality of the connections for people in general and i was having concerns about 10 cards with only 1 hiper arc and only dual 70am power supplies. matthew At 04:50 PM 1/15/2003 -0600, you wrote:

We don't seem to have any problems running this way, but we don't do any extra routing or tunnels with the ARC. If you are wanting to utilize OSPF or anything I would suggest you put in a HiperARC with 128MB. But we have had success with the following code versions.

HiperDSP 2.1.9 HiperARC 4.2.32 upgrade to 5.0.9 for TCS 4.0 NMC 7.1.8

I'm not sure about your speed question... SNMP access is much better if you upgrade to the NMC333 and the newest ARC but I'm not sure that alone makes it worth it. If you would only be upgrading to hiperARC128 and HiperNMC, it's unlikely you would see much improvement, but you would open your ability to upgrade to TCS 4.3 and with dual 130s up to TCS4.7 As far as call handling goes, I've not noticed a problem using the older Cardsets.

With a non-HiperNMC you are limited to TCS 4.0, so keep that in mind when you think of V.92 :)
