The voltage means nothing. It is the FSK signal that produces the visual. The FSK will trigger the light on the system just like a VM light on a Call ID box. The stutter is sent from the CO via the signal from the VM to the CO to the box that sends the FSK signal. Your stutter would be 2 volts higher, you do not have stutter voltage on the line. I suggest you have them check again. There is so much to go wrong with all the inks and fsk signals. They need to be sure all signals are present at the proper voltage ate both locations. I am familiar with phone company setups which should be similar, but I do know for a fact that they use a 5ESS switch and it is probably setup the same way. On the 5ESS the stutter and visual can be set separately or combined. Brad

I would not use more than two AAs (3 volts). Try reversing the line polarity. Generally the phone interface doesn't have that type of control, it might be programmable to provide 24 or 48 volts. I could suspect a tone level problem, but not with other devices working fine detecting the tone and cadence. Is the line wired back into the old house phone wiring? Did they have a recent lightning hit nearby? Also check if the cable back-up battery is ok, (customer's responsibility) it could affect the line voltage. Might be helpful to have the exact voltages you were reading. good luck -l Bob wrote: > Two Customers with KX-TA824 phone systems.

A SL phone plugged into the Cable Modem responds with an audible stutter and a visual display. A small Panasonic portable base parallel to the 824 responds with both audible and visual. The modem is within a few feet of the KSU so there is not a line loss issue. > > The White Plains, system, now ONLY gives the visual [light blinks] but no audible stutter. > > A voltage reading at the cable modem shows the white plains system with two more volts DC when OFF HOOK than the Greenwich system. On Hook, the voltage is the same. Also, with only the SL phone connected to each system and a voltmeter, the voltage at stutter is 2 volts higher in White Plains than Greenwich. Cablevision claims that if the stutter is at the cable modem, they have no further responsibility. I claim they have lowered the output voltage of the modems. > > I have defaulted both systems and re loaded the programs.
