So, you are saying this actually does work, or are we not sure? Our
ratios aren't that good yet, but say I had 40 Modems in the 1st PM3 and
40 modems in the 2nd PM3. Then 40 people call in all with modems, they
would of course go to the 1st PM3. Then another modem call comes in, it
would automatically go to the 2nd PM3. If an ISDN user calls in he would
connect to the first PM1? and so on and so forth?
If this is indeed the case, we have got to start pushing ISDNs hard.
I was under the impression, that they would just get the silent treatment
you talked about, when they dialed up and there were no more modems.
