G.Princess and Trimline telephones - DPA will not operate with "Princess" or "Trimline" telephones, which have the keypad in the handset. The electronics with which the DPA interacts are not accessible in these telephones.

H.Tone dialing - Make sure your modem is configured for Tone (DTMF) dialing. Your DPA will not work with pulse (rotary) dialing. Your modem user guide or operating instructions should describe this procedure.

I."No Dial Tone" error message - The “No Dial Tone” error message is presented when the modem doesn’t receive dialtone or recognize what it is receiving as dialtone. Some telephone systems encountered in North America (such as Rolm or Siemens) and most foreign telephone systems do not use the standard dial tone. Your modem software will normally require your modem to detect dial tone and may not recognize non-standard tone as dial tone. The Hayes command

X1 or X3 will tell your modem to dial without detecting dial tone. This is the same command used for Blind Dialing.

J.V.90 Connections - Although the DPA is compatible with V.90 modems, the maximum connection speed through the DPA is normally 33.6Kbps. Your connection speed will be determined by the phone system's capabilities, your modems capabilities, and the quality of the phone line. When using the DPA, your connection is going through a digital phone system, which was not designed for data communications. Your connection speed will probably be slower than you would get on an analog phone line. In fact, V.34bis/V.90 connections at 28.8Kbps, 24Kbps, and 21.6Kbps are common.

K.Hanging up the modem - The DPA disconnects the “Handset” jack when your modem is in use. After data transactions or when autodialing voice calls, use your communications software to hang up your modem so that the Handset jack is reactivated. The manual that came with your software should describe how to hang up the modem.

L.USB Ports - Located next to the USB I/O cable are two USB ports. These ports can be used to connect low-powered USB devices.

M.Lost or Missing User Guides - In the event the Quick Setup Guide is lost or missing, you can download this DPA Quick Setup Guide from our website at www.konexx.com/dpa/index.html. Also available on our web site is a more detailed DPA User Guide.
