My understanding was that pulse dialing from a channel bank was "iffy", but not pulse reception, so long as the channel bank properly reports on/off hook state - that there is no real "pulse detection" in the channel bank, simply on/off hook status (looking at some of my documentation, "real" D-2, D-3, and D-4 channel banks all used the LSB in the 6th code word to indicate on/off hook status). Is this no longer correct? I'm using ESF, although I think D4 would work similarly for this function.
I will contact Rhino as well, though - just to cover my bases. I was very impressed with their support previously.
