Phil, Sounds like you have an intermittent short on the data (yellow,black) pair of one of the stations.
On the 624, a direct short on a data pair will cause the system to shut down - a momentary short can make the system reset and appear to shut down for a minute - a very slight short can cause problems only during "Higher Voltage" transmission ( ** such as the 60-95 volts sent to the slt for as ring generator **)- this causes the "Pre-Tripping" during the first ring - like your getting check for the following...ask about any other contractor type of work that was recently done at the site. - water leaks/damage, dirty jacks, water damage and corrosion at the jack. (splashing water into a jack next to a plant while watering the plant is very common in the residential install.)- carpet installers might sometimes partially cut into a wire with their razors. staples that go through the cable instead of around it during installation -etc... Your best way to attack this problem is if you can make the problem happen. ----at the ksu - disconnect all station plugs (make sure to label them first) and then call in from a cell phone or fax machine. while the caller is getting ringing, start plugging in the stations one at a time until the problem or cut off occurs. this will tell you which cable run is your problem. the problem/short could be in the cable, the jack or sometimes the actual phone. usually you will find a dirty or corroded jack or a bad modular crimp for this location. while troubleshooting the problem the first time, you might have played or jiggled the wires at the ksu - this might have temporarily fixed the problem dumping the data might not have been what fixed it . While touching and jiggling the wires or simply removing the cover to the 624, letting the cables move around slightly or stuffing them back down when replacing the cover, you might have de-aggravated the short if it was a bad modular crimp. ***when buying your modular plugs for crimping - keep in mind that there are two different types - 1 type for solid wire and another for stranded wire - using the wrong plug can cause bad connections and cause "WEIRD PROBLEMS"*** also make sure to always use a good crimp tool (this means spending more than $3.99 at Radio Shack) - also try to mount any surface-mounted jacks facing sideways or facing down, which usually helps to prevent dirt or water from getting into the jack. Good luck and let me know what you find - JOEL WEISER -----Original Message----- From: [EMAIL PROTECTED] <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Date: Monday, October 22, 2001 10:08 AM Subject: KX-T: 624 weirdness >Hi all > >Anyone run into this before ?
