Re: (usr-tc) Quad modem x2 tx level
Hi Dan, There are slight differences in setting between modems from different country settings, as our modems must comply with the different country specification settings set by each Telco , ATI7 tells you your country code setting. Country like US/Canada , Japan, Finland, Sweden, UK, Norway, South Africa, Italy, New Zealand, Czech / Slovkia, Belgium, Denmark, Austria, France, Germany, Austria , Ireland , Spain, Portugal and Malaysia all have very slight difference in values and limits, what you are seeing is more likely differences in modem country settings , we also have a country code setting that covers International ITU-T spic. By the way -10 dB is a stronger signal than -12 dB Hope it helps Ray W Dan Borlovan <danb@dnttm.ro> on 30/01/2000 09:22:41 Please respond to usr-tc@lists.xmission.com Sent by: Dan Borlovan <danb@dnttm.ro> To: usr-tc@lists.xmission.com cc: (Ray Whelan/IE/3Com) Subject: (usr-tc) Quad modem x2 tx level Hello, In order to try improve user x2 connect speeds, I tried to raise the x2 transmit level on quad modem cards.

So what db level do you recommend that the quads be set to assuming we're in the US? What about the dsp's? At 08:54 PM 1/31/00 +0000, you wrote:

Hello,
In order to try improve user x2 connect speeds, I tried to raise the x2 transmit level on quad modem cards. The problem is I have two quad modem models (analog/digital vs. digital only) and the first don't let me go higher than -12dB, while the other ones happily accepted -10dB (this is as far as I may go from the telco point of view)
Now the only difference between modems is the analog capability (referring to the possibility of getting signal from nic or pritdm) and the country code.
All modems are setup as digital, taking signal via pritdm from e1 card.
Is there anything I can do about this one?

Is the modem enforcing a maximum signal level on country-code basis? If so, can I bypass this limit?
By the way -10 dB is a stronger signal than -12 dB
Yes I know, and -10dB gives me better x2 connect speeds.
