Also this post from bigindian below is interesting:
"CS1000E does not slot VGW cards, they are daughter boards on the Media Gateway Controller of each MGC cabinet, they are built on 0,9,10,11,12,13 pending on the number of channels you wish to have - 32,64,96, etc, up to 2x96 - 192 channels. I see what you're saying, yes, if I have and MGC with 64 VGWs on MGC 4, then 4-0-0-0 4-0-9-0 each thru 31 for 32 chnls each"
I am only aware of 128 max VGWs per MGC and any expansion daughterboard has to start at 11. I don't believe that 9 and 10 are available. I suppose if you didn't put cards in slots 9 or 10 on the MG expansion chassis maybe it allows for such. I also didn't think slot 2 could handle a 96 high density daughterboard (which is why you can only put a 96 in slot 1). So, how can you do a 96 and 96 for 192 total?
That is really cool if you can have 192 channels - can you go into a little more detail about this so I can kick the crap out of our vendor?
