There was some discussion on transmit levels a while back -- check the archives. If I remember right, David Bolen said that ANS made a habit of setting all their modem pools (for AOL mostly) to -13dBm.
nod, I have those emails. The thing is, that was on the Quads. The quads could do analog or digital. The default modem templates were optimized for analog calls not digital. So you would have to make some changes to the Quads to optimize for CT1/PRI.
David did clarify however that the HDM's didn't have this problem. But that was when they first came out, who knows whats what since then.
FWIW... I just blew a 2.0.81 DSP back to factory defaults and it comes up set to -11 now, instead of -12 like it used to. So it looks like both Quads and DSPs default to -11 now. (Courier I-Modem still does -12 on my BRI at home... that would be interesting to experiment on...) Anyway. Given that the measured level and the programmed level tend to vary on both 3Com and Ass^Hcend stuff... anyone have a new consensus as to what we should be using instead of 11? 13? 15?
