Do you have to buy one of the new HDM's to get the 96 channel capibility, or can you simply swap out the NIC portion of the HDM? In other words, is their an upgrade path?
You'll need to buy the new NAC. The current DSP's only have 24 (30 for E1 versions) modems on the card, so you can't handle 96 calls on the current NACs.
Actually, the current NAC's have 6 DSP's, each emulates 4 modems. I heard that these same cards were able to actually do 8 modems per DSP about 2 years ago, and thought maybe they pushed it even further. The plan worked out nicely when 3Com envisioned it: 14 slots, 1 hdm per slot, 23/24 channels per slot, 1 pri/t1 per slot but once they were able to double to 8 modems per DSP: 14 slots, 1 hdm per slot, 46/24 channels per slot, 1 DS3 for the chassis that was the rationale behind using a utilization meter on the front of the HDM NAC vs. a 1:1 LED per modem mapping, since this way they could expand the NAC DSP-wise........... The sad part is they probably have the software but won't release (the software existed 2 years ago or so..........inside sources tell me) (that is the software to double the modem emulation of the DSP's) brian
