My INADS line on a G3si does not answer and internal analog line. POTS line on this PBX is dead.
This is the second G3si that I have found this on. Can anyone tell me why?
 
I have found that sometimes swapping the tip and ring on the punch can resolve the issue.

I have also had processors whose modems just fail.

The only work around is to install a PC on site you can remotely access or install an external modem on the Term.

Clowns to the left of me, jokers to the right, here I am, stuck in the middle with you.
 
Try this as it has worked for me in the past, do a reset system 1 and then retest inads line access

Thanks Have tried all those including flipping tip and ring.
I even changed the PPN carrier on the first one. When t so far as to replace the entire control set Processor, netpkt intrfac translations tone clock and maint board.
Even changed the Ring Gen. I'm lost

 
are you sure the dial tone is on the 25th pair of the aux cable? do you have dial tone on the 25th pair on aux cable? maybe you have a bad aux cable may need to replace aux cable

Also you stated this is an pbx dial tone for inads line, have you tried a test set and call the analog extension and see if it answers?

Double ring on DID call may not answer.
Check to see if station to station call (single ring) connected to v-sl aux cable rings and modem answers.

Code:
display station 6000                                            Page   2 of   3

Analog port should be on tn742B, tn793, tn746B (need -48vdc)
some older analog tn769 and tn742, tn746 may not have the correct voltage to operate.

Does a 1FB line work.

modem is on the processor board g3si
modem is external prologics
modem is tn1648 for g3r (different packs support different baud rates.

tn711 processor - r1v1 up to r1v3 - internal modem max baud 1200
tn711b processor - r1v1 up to r1v3 - internal modem max baud 1200
tn773 processor (286) - g1 or r1v4 and r1v5 - internal modem max baud 1200
tn759 processor (xe) - r1v2 up to r1v3 - internal modem max baud 1200
tn786 processor - g3v2 up to g3v4 - internal modem max baud 2400
tn786b processor (386) - g3v2 up to g3v4 - internal modem max baud 2400
tn790 processor Raptor - g3v5 up to g3v8 - internal modem max baud 9600
tn798 processor Raptor - Prologix g3v6 - g3v8 - external modem max baud 9600
tn1648 v4 Sysam - g3r - g3v1 - g3v11 - internal modem max baud 1200
tn1648 v5 Sysam - g3r - g3v1 - g3v11 - internal modem max baud 2400
tn1648B Sysam - g3r - g3v1 - g3v11 - internal modem max baud 9600
tn2402 processor Raptor - Prologix g3v9 - g3v13 - external modem max baud 9600
tn2404 processor Raptor - g3si g3v9 - g3v12 - internal modem max baud 9600

Just to mention my Bonafides...I manage over 56 Definity G3si/G3r for the last 16 years. The internal analog line connection was setup by me on over 30 of these and all but these two so far work great. For many years I polled these PBX daily with usr robotics modems collecting configuration, station, and traffic reports with no real issues other than the

The line when Lifted off the aux block BP-25 an RJ-11 jack on it and plugged into a Buttset, USR modem, Intuity all work good.
TN2404 processor G3si V9.05 software. Data restriction only comes into play After a call is up. Nut I do set it to "Y" when setting up an internal INADS lines + the 4 entries below it.
When a regular POTS line (loop-start in this case) is available it works just fine. The analog station is set to 2500 although I have to use 500 for G3r/TN1648/B switches.
What you said about the TN746 is interesting. The card currently installed is a TN746B V10 seem recent enough. I have matched that to several other switches where this works and they are using the V10 version. I have over and over again tried different analog board and flipping the tip and ring with no success. It is almost as it the Ring Generator or Tone clock (Tn2182B) act differently for an internal analog line than a direct loop-start POTS line.
That tends to get into the whole FXO/FXS discussion which leave my head hurting. There is something different in the signalling of an analog port than there is with a Loop-Start POTS line from the CO. If I had a good Digi smart test set I could see what shows up but I do not.
I apologize for getting so winded. But these kind o f problems stew around in the back of my head for years until I find a good answer. I would efinetly appreciate any ideas or information you might have.




 
and yes the 1FB works good when it is working. Just so happens this problem started with what I thought was a bad Processor Modem at a site with a bad SAT terminal. While arranging for another processor and a SAT terminal the site underwent some sort of a power problem that left the switch in an uproar of Insane Hyper activity and had to be powered down and reset. I don't get all the easy ones.
 
One thing I noticed in your post is that you stated you have the line setup as a 2500...every switch I have is setup as a "500" not sure if that will do the trick but worth a shot. You have changed everything else..and like Tier3 said if you have a 742B, 746B you should be gold...Not sure what you have going on there...but no reason it shouldn't work on a 9.5

Good Luck

the 500 setting sets the analog station to pulse for the outbound dial mode of the G3r TN1648/B System Maintenance circuit packs.
The TN790/B and TN2404 and others very well to Tone.

Yes it has me stumped. I was hoping for some peice of magical advice ..Like set you incoming dial mode to razzale Dazzle. Because it is happening on Ver 8 and Version 9 software. And the processors have been changed out. I am going to have to get the replacement circuit pack sent back to me for testing.

Thanks all. If anyone else has any ideas I would very much like to hear it.




Fix it right the first time if you can. It just works better that way!
 
If you connect a 1FB, does the modem answer when you call it?

Historically no. In this case since changing the Processor. The POTs line is bad. Which I assumed took out the Processor modem. Which I replaced the processor.
Whose modem has not yet proven working. No it does not. I am assuming that a 1FB is == a Loop-Start POTS line.

Remote tech with limited access to site 1,000 miles away creates certain logistical problems that must be overcome.
Working on getting the LEC to repair the POTS line. Then I have to get the Tech who is at best 1.5 hrs away to the site.

Fix it right the first time if you can. It just works better that way!
 
Your tn790 or tn2404 is bad if a 1FB or loop start pots line will not answer with modem tone when connected to the processor via v-sl of your aux cable and you have verified the wiring.

tip & ring pins 50 (v-s) and 25 (s-v) for INADS (missing t&r will produce Maintanance board minor alarm 1025 and possibly 513 errors)

send tech with replacement card.
card can be plugged in, software on card does not matter. power up and it will load default software and modem
should work. You can also do this with current processor board to test. No flash card loading xln is necessary.

Thanks And that takes me back to my original question. A 1FB works but an internal Analog lines does not. Only for two PBX's out of 58. The reason it is so important is that these two sites historically have bad OSP that does not belong to me. Trying to bypass this problem but the processor modem does not answer an internal 2500 station. It has mystified me onthe other PBX for 4 years. I end up having to wait for the cable to dryout and lately set the modem baud down to 300. very annoying.

If 1FB works, a station (correctly programmed) will work.

processor board cannot distinguish a station from a trunk that has the proper electrical parameters

Code:
                         CO Loop-Start Trunk Specifications
                           Parameter                        Minimum   Maximum
       Loop Current (Active State)                           20mA      90mA
       TIP or RING to Ground Voltage From CO (IDLE State)   Note 2    Note 2
       TIP or RING to Ground Voltage On Port (IDLE State)     **        **
       TIP to RING Voltage From CO (IDLE State)               0V       105V

        2. Because of the floating battery CO, in general, a
           voltage to ground on the trunk may not be measured.
           A more general TIP to RING measurement is
           recommended.

tn-746

-24 VDC OPERATION TN-746 See G3i System Description Section-2-63.
-48 VDC OPERATION TN-746B

TN-746 is IN BUILDING ONLY with simultanious ringing to only 4. .
TN-746B is IN OR OUT OF BUILDING with simultanious ringing to 8
(4 ports on each half)..Other ports dialed when maximum are
already ringing will receive BUSY TONE.

Ranges:
TN-746.....3100ft (24awg)....2000ft (26awg)
TN-746B....20000ft (24awg)...13000ft (26awg)
TN-746B with 7100 series analog set...15200ft (24awg)...10000ft (26awg)

TN-746 does NOT support NEON MW Indicators (will support LED).
CONFLICT HERE, Old G1 documentation says NEON-YES, new G3 says NEON-NO!!
See G3 Sys Desc under Analog Line section 2 iss 1 July 1993.
TN-746B DOES suport NEON and LED MW Indicators (on premise).
MUST have a TN-755B in the carrier of the station for NEON MW Indicators.

TN-746 WILL NOT SUPPORT Line Status Indicators, answering machines,
modems, or amplified handsets. ('B' WILL)

And that is technical documentation. I'll put that in the memory blocks.
The analog station is programed as
Type: 2500 on a TN746B V10 port COR FRL of 6 Loss group 1 Off Premise N
data restriction Y Line apperance = call-appr.

Just got the 1FB fixed and the Processor answers at 9600 baud clean as whistle.

Will a Digisamrt test set give me parameters of Voltage, current and timing to quantify the difference between a 1FB and an analog port?

Are there any programming entries on "System pages" other than the anlog port that might effect how the internal analog lines react. Loos group.. country options, multifrequency-signalling etc
