Had a customer call me to say that no room phones ring when called. Every thing else appears to be working fine according to the GM.
I have no spare 200 Analog parts to take with me but I was told there might be a fuse or fuses on the interconnect board that controls the ring generator.
Any thoughts? I am trying to hunt down my 200 Analog manuals but in the mean time any assistance is appreciated.
There is, I think it's F1, but the rear door power supply has no fuses on the system ring generator, just on the nite bells ring generator. It fails every now and then.

Sounds like you lost the ring generator on you back door power supply. I know EXACTLY where you can get a replacement!!!!
But bring a strong back, darn things are 90+ pounds! I've never had the R/G fail, it's always been 1 of the 'little' voltages. I'm guessing that door has been repaired before.
The fuse on the interconnect board only affects the printer port and console.
Does anyone have a list of the voltages and test points since I still can't find my manuals?
I might mention that the backplane has been failing on this unit or at least no cards work in the right half of the top shelf anymore.
On the top left, and bottom left corner of each shelf, the screw terminals/test points are marked with the proper voltages. All of the voltages are DC, except the 90V, which is AC. I always use the -48 terminal as my neutral, when testing the AC ringing voltage.
"no cards work in the right half of the top shelf anymore."
------------------------------------------------------------------------------------------------------
Probably not the problem, but the earlier cabinets had 2 fuses on the backplane of each shelf for the 48 VDC feed. One for slots 1-6 and one for slots 7-12. They were there to comply with some early NEC rule, which as it turned out, didn't apply! Open the back door and look along the bottom edge of the PCB on the back of the card cage. If there are fuses, they can be bypassed, or replaced. Yes, it was a MITEL approved field modification. Later production just had jumpers where the fuse clips used to be. I just soldered an 18 ga. wire to the fuse clips. Be quick because if you melt the solder where the clip is soldered into the board, you'll do more damage then good.
Customer wants to "bandaid" the unit until they have the money to upgrade (going on 3+ years now) so I will be changing out the R/G for them. All other voltages are correct and I found the faulty fuse to fix the shelf issue.
Thanks everyone for their assistance.

Hello,
I have an issue with Mitel 3300 and Juniper SSG20
Plssssssssssss help.
There are two sites (Site A and B) that are connected by SSG 20 on each side via site-site VPN. We have SIP links coming into each end from the SIP provider which is NAT'ed to the Mitel controller. I can call extensions inernally across the sites and vice versa. However I'm having some issues:
1. Call comes in on site A, gets call attendant, request extension on the site B.
If someone answers there is no audio either direction.
If no one answers, caller just has dead air until the call dies.
2. A call comes in to the site A and is answered locally, then needs to be transferred to site B.
If done via conference the call is connected and communications works until the site A user hangs up, then both other users get dropped.
If done via transfer, the incoming caller gets dead air and the remote caller does get the ring but no audio
I have tried enabling SIp, etc. Pls help me to fix this issue.
Thanks
Sharu
LH yes we are!
Sharu,
Start another thread for your issue so more people see it. You don't want to add a comment/question on a completely unrelated thread. On this thread we are talking about equipment that is 20+ years older than the 3300.
Thanks everyone,
I replaced the R/G and the fuse it blew when it went and all is well in Whoville! The old R/G smelled and when I turned it over, 2/3 of the back of the circuit board was scorched (Ouch!). Word to the wise, if you have to replace this thing, make sure you have a long slotted screwdriver otherwise getting the cage off of the R/G can be problematic. :bang:
Jon, are you kidding! Why didn't you just replace the whole back door?! You'll probably be back out there in 6 months or less to replace the whole door!
LH,
Wanted to but the customer didn't want to spend the money. This was the only other option I could give them.
Supposedly want to upgrade to an ICP in 4- 6 months going on close to 48 months now.
Customer had lines disconnected (had a T1 w/channel bank and now down to 8 lines) without calling me and now every time the system is rebooted 4 trunk cards send alarms and the just sit there and flash. Customer didn't even want me to go through the programming to fix the line issue because the owner didn't want to spend the money.
One of these days the unit is going to fail and then it will be an emergency, especially if the Dean card goes bad.
Sounds like they deserve whatever grief they get. But then they expect you to jump through a hoop while bending over backwards to get them running again.
Amen, Steve!
The sad part is the owner just changed flags and spent 800+k on required renovations and didn't think to include an phone system upgrade in it. :bang:
Hey, everybody knows 'Mitels never die'.
