All, Experiencing some issues on my FXO lines. If a call comes in on an FXO and then get transferred to another FXO (say to call someones cell phone), those two lines will stay tied together indefinitely. This happens to us when we transfer an incoming call to our on call guys after hours and on weekends. We have installed 3 other * boxes and they do the same thing. We use a Adit Channel bank

Hej! Hope nut-upsuser is an appropriate place to post additional info about the smartups protocol, please tell me if not. I got an APC Smartups 2200 (5U Rack Mount, European/230V version, 48V batteries) a couple of days ago, was very happy to find the protocol description at http://www.networkupstools.org/protocols/apcsmart.html, and started to play. At the point when everything was working

Leslie, This message is most appropriate for the NUT user list. I kept Rik Faith's and Nicholas Kain's copyright information because the tripplite_usb driver borrows heavily from the tripplite (serial) driver, but they are not responsible for the mess that I made in the USB driver. See below. On Dec 28, 2008, at 5:28 PM, Lelsie Rhorer wrote: > Gentlemen, > >

Hi, I am sorry for possible offtopic as this question is not quite NUT-related but I cannot imagine any other place with people of such deep and intimate knowledge of UPS behavior. One day all of a sudden my APC Back-UPS RS 1000 refused to go online (green led) even though mains was connected. I used upsc to see what is going on, and ups.status was "OB DISCHRG", battery.charge was

For my Smart 2200, a charged battery string is anywhere between 25.6 and 26.8 volts. I'm seeing nut report 13.0 volts, which seems suspicious. Even if the UPS were reporting half of the actual battery voltage to keep protocol compatibility with models having a 12V battery system, the value of exactly 13.0 seems unlikely. According to the page at

Maybe the UPS sends a LB event and shuts down

...ause it's worked on Dialogic cards, which reported hangup, not busy detect (while when I connect a Dialogic card to a PBX, I have to measure the busy signal's frequency/cadence or it doesn't disconnect). I couldn't tell for sure - I don't have a phone with a light, and the only voltmeters I have are digital, no way to see if there is a drop to zero between the several volts when the line is offhook to the 47 volts when it is onhook. But * would only recognize hangup if I unplugged the PSTN line. Otherwise it would play my voicemail menu over and over if I hung up without choosing...

Hi All, I have what is probably a 12 year old (or older) Compaq R3000 UPS plugged into a FreeBSD 8 system running NUT version 2.6.5 This UPS contains a total of 16 batteries in 2 banks of 8, each battery is 6 volts and the bank produces 50 volts. The UPS monitors battery voltage and the battery charger in the UPS works like this. For about 2 days it will apply a charge/float/topping

Ok... I asked a question a few months back about a 7960 that a user claims to be "shocking" her in her ear from time to time. A few others indicated they had similiar issues and alot of them seemed to stem from power over ethernet. Here's what we've done... We replaced the phone, ran two new cat5 cables to a different switch, put in a power brick and disabled power over

I have the same issue of incorrect output voltage being reported by usbhid-ups, as run on NAS4Free (FreeBSD). UPS is as shown below. There is a thread on this list from 2014 that has these same issues, apparently never addressed by any of the later usbhid-ups releases. I?m using 2.7.3. The value I am especially concerned with is the output voltage; if ANY thing should be right on the report, it?s

Hello, Somewhat off-topic, but seeking some input from other tech folk on this list. I have a Tripp-Lite SMART 2200 (a white tower that looks similar to, but predates the black SMART2200NET) that just failed its monthly battery test so I bought new batteries and replaced the old ones. Sadly once put back together, plugged in and enabled it did not power up--no lights, sounds, smoke, etc. I took

Does anyone have disconnect supervision working on their TDM400P or X101P cards (to/from the telco)? Googling "telco disconnect supervision," I found the following description: http://mirror.lcs.mit.edu/telecom-archives/telecom-archives/TELECOM_Digest_Online/1559.html [cut] Re: How Do I Get "Kewlstart" From my Phone Company?

I connected two plain old telephones to FXS lines of a TDM400P (defined as fxoks in zaptel.conf), one of them dials the other with Dial(Zap/2), I talk to myself for a while, hang up either of the phones, and the phone that remains off-hook gets the congestion tone until it goes on-hook (at least as long as I've cared to wait). I don't have a voltmeter on the line, but if I'm hearing

Hi, I have had this issues for ages but have ignored it, but my handsets get faint background crackle on the FXS port. When I connect the handset directly into my PSTN, it goes away complete, so I am generating this from somewhere in my asterisk box. I get it immediately when the phone goes off-hook and it stays through the dialing and call progress. I can't think of any other devices

Hi: I'm using a TDM-400 to terminate PSTN lines at my Asterisk server with kewlstart signalling. When an outside caller calls the server, the TDM-400 goes off-hook and provides a ringing tone to the caller. If the caller hangs up before the receiving party answers the phone, Asterisk fails to detect the hang-up. The TDM-400 stays off-hook, hogging the line, while Asterisk rings the

Gentlemen, ??????????? I am running a Tripp Lite OMNISV1500XL under NUT using the tripplite_usb driver on a Debian "Lenny" Linux system.? The platform is an AMD Athlon 64 x 2 processor running kernel 2.6.26.? The driver is up and running, but there are several issues. ??????????? First, the system drops communications with the UPS regularly - typically 2 or three times an hour.?

Hi - I have an fairly vanilla answering machine (actually its a combo cordless phone/answering machine) attached to an FXS port (on a TDM400 Card). Everything is working as planned except I seem to be having a bit of trouble with the answering machine. After is answers it plays the outgoing message and then hangs up before letting the caller leave a message. (it actually hangs up before the

Hi, I just got and setup a new ip500 yesterday and it worked for about 15 minutes. Then it froze during a reboot.Now, when power cycled, the logo comes on for 3 seconds and then the screen is blank and nothing further happens. 468* factory reset doesn't work. I am about to send the phone back, but wonderd if anyone had a suggestion first.

I am trying to obtain optimum gain settings for a bank of analog lines connected to a channel bank. My telco has provided a 'Type 102' test line to use for incoming level calibration. This is functionally equivalent to app Milliwatt(), but provides tone from the CO inwards. Question is, how should one use this a 0dbm test source with ztmonitor? Am I correct in understanding that a 0dbm
