Dedicated Transmission Parameters SM 105 B786 B786 Fax Option 4.5 DEDICATED TRANSMISSION PARAMETERS There are two sets of transmission parameters: Fax and E-mail Each Quick Dial Key and Speed Dial Code has eight bytes of programmable parameters allocated to it. If transmissions to a partic ular machine often experience problems, store that terminal’s fax number as a Quick Dial or Speed Dial, and adjust the parameters allocated to that number. The programming procedure w ill be explained first. Then, the eight bytes will be described. 4.5.1 PROGRAMMING PROCEDURE 1. Set the bit 0 of System Bit Switch 00 to 1. 2. Enter Address Book Management mode ([User Tools]> System Settings> Key Operator> Address Book Management). 3. Select the address book that you want to program. 4. For the fax parameter, select Fax Dest. , for the E-mail parameter, select E-mail, then press “Start”. Make sure that t he LED of the Start button lights green. 5. The settings for the switch 00 are now disp layed. Press the bit number that you wish to change. 6. To scroll through the parameter switches, either: 7. Select the next switch: pre ss “Next” or Select the previous switch: “Prev.” until the correct switch is displayed. Then go back to step 6. 8. After the setting is changed, press “OK”. 9. After finishing, reset bit 0 of System Bit Switch 00 to 0. 4.5.2 PARAMETERS Fax Parameters The initial settings of the following fax parame ters are all FF(H) - all the parameters are disabled. Switch 00 FUNCTION AND COMMENTS ITU-T T1 time (for PSTN G3 mode) If the connection time to a particular termi nal is longer than the NCU parameter setting, adjust this byte. The T1 time is the value st ored in this byte (in hex code), multiplied by 1 second. Range: 0 to 120 s (00h to 78h) FFh - The local NCU parameter factory setting is used.

Also, try using the cable equalizer if one or more of the following symptoms occurs. Communication error with error codes such as 0-20, 0-23, etc. Modem rate fallback occurs frequently. ƒ Do not use settings other than listed on the left.
