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.
OK...the original DSPs cards had a dsp chip for every two modems...the newer DSP cards have a dsp chip for every four modems (same code base). They (according to what I've heard) are basically the same type of dsp chips...but the newer ones are a newer version...thus the capability of handling more modems. I was not under the impression that it was just a software change (though that certainly is possible).
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...........
They also just plain didn't have enough room for 24 leds for modems along with carrier, alarm, loopback, fail, and power leds. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
