But I can`t understand why HiperDSP not support 2800 symbol rate, supported on other USR modems line...
Dunno... I can try it out here tomorrow. I don't seem to have any calls up at 2800 right now, though I did have some at 2743...
And other strange thing like that: We are made wide statistical test calls for compiring Cisco (AS5300, MICA modem) and USR Hiper NASes and get very strange output. All calls on Hiper would have more power reduction on high frequencies, in comparison with MICA. For sample two typical calls (from 200 calls series) at same time from one point and one modem:
You can tweak the transmit power on the DSP's, though I'm not sure that's what you're shooting for...
But I would be *very* interested to see if there's a way to get anything this low-level out of *any* modem... (I'm still hoping I could use something like that to ID the brand of modem at the remote end -- that would be *great* for troubleshooting.) So how did you get the INFO0 bits directly? Please share. :) Not I am. It maked for me one INPRO company engeneer who write code for modem based on Lucent (AT&T) 1634 datapump. He know many backdoors for DSP. As I belive all modem on that chipset may give handshake sequince for human who know secret word... ;-))
Ah, so you got it from the client side, not the server side. I did dig around and found documentation on Lucent's web site that says how to pull the v.34 bits out of an LT Win Modem. Not too secret after all... :) - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
