Matter of fact, I have no idea what that term could mean. The FCC regulates the output power a modem may (legally) transmit to the phone line, and last time I looked the level was still -9dBm. The user has the ability to boost the output level (resistor change) in order to operate over leased lines, but it's illegal to do that for the public switched network in the U.S. and Telebit doesn't advertise that ability for dialup use. Sounds like a spec sheet was misinterpreted, or somebody's writing their own spec sheets for the T1600... > ism!wilbur!techsys!pain!adamr -- .------------------------------------------------------------------------. | Greg Andrews | UUCP: {apple,amdahl,claris}!netcom!gandrews | | | Internet: gandrews@netcom.COM | `------------------------------------------------------------------------'
