You can't solve the problem unless you know what you are dealing with. Have you tried placing a standard telephone (mechanical ringer) across the line to check for ringing characteristics? If there is a problem when connected directly (no other loads) it is your telco's problem. Be sure to check the phone at the office before you leave for the site.
Where is the customer located? Maybe someone on this list is nearby and wouldn't mind taking a fresh look at it. Have you tried connecting the KSU directly to the incoming line (no other wiring involved)? Additional loads on the line can overload the CO ringing generator. We have had several cases locally where the lack of incoming calls, or reliable ringing was caused by a faulty Ring Generator at the CO. You need a voltmeter that will read accurately at 20 Hz. Take all loads off the circuit and measure the ring voltage for an incoming call. You could also use an oscilloscope, but remember you are dealing with a balanced line, so you may need two probes and a differential input. Place the KSU only on the CO line and measure the ring voltage -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rob Harrison Sent: Wednesday, April 11, 2007 5:58 AM To: kxt@kxthelp.com Subject: KX-T: KXT-624 Stuttering/Clipped Ring Problem, Continued Thanks for all the suggestions on testing line voltage, getting the phone company involved, etc. Unfortunately we haven't been able to schedule a service call with the customer yet, and are hoping to have some kind of interim solution to put in place next time we visit. The problem may take some time to clear up if the phone company has to be involved, and the customer is quickly losing his patience since the complete replacement of his KXT-624 did not solve the problem. Does anyone know of any devices that can detect an incoming call and generate a full ring, whether or not the incoming call signal is interrupted or weak? We're hoping to install such a device between the verizon NID and the KXT-624 on all incoming lines, hoping that it will cause the system phones to ring normally instead of clipping off when the verizon line voltage fails (assuming that is the problem). Thanks again, Rob H. _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
