Hi all, Yesterday, in an attempt to take back my phone room, I pulled everything apart as far back as the demarc and rebuilt it. In the process of putting things back together I accidentally connected my incoming lines to my FXS ports and my phones to my FXO ports. I quickly realized the mistake I made and corrected things but not before one of my FXS modules was smoked by incoming ring voltage. dmesg now says: Freshmaker version: 71 Freshmaker passed register test Module 0: Installed -- AUTO FXO (FCC mode) Module 1: Installed -- AUTO FXO (FCC mode) Boosting ringinger on slot 3 (89V peak) Module 2: Installed -- AUTO FXS/DPO Timeout waiting for calibration of module 3 Timeout waiting for calibration of module 3 Proslic Failed on Second Attempt to Auto Calibrate Proslic Failed on Second Attempt to Calibrate Manually. (Try -DNO_CALIBRATION in Makefile) Module 3: FAILED FXS (FCC) Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules) Registered tone zone 0 (United States / North America) Registered tone zone 0 (United States / North America) Has anyone else seen this? Also, wouldn't one assume that a module designed to generate an 89V ring tone could also accept it without being destroyed? I've tried sever hard and soft resets to revive the module, reseated the card and the module and moved slots to no avail. Can anyone thing of anything else to try?

One would think if it can generate it it can survive it as well....>>> matt.riddell@sineapps.com 24/05/2005 04:07 >>>Ian Pattison wrote:> Hi all, > > Yesterday, in an attempt to take back my phone room, I pulled everything apart as far back as the demarc and rebuilt it.

It's hard to protect against voltage you should be able to generate because the protection circuitry would kick in when YOU generated it too. Speaking as an EE (but nondegreed, I've just been doing it for 10 years) you *can* design in tricks to work around these issues but they just jack up the cost on the device and this is already a cost-sensitive market. I don't blame Digium for not including it at all. Basically it's like saying your portable gas generator should be able to take having 120V applied to it since it can generate 120V. It just doesn't work that way, I'm afraid. -A.
I guess I need to go over my college electronics again... it's been a while.
