I just replaced the DCS 70 in our office with a "DCS" (dcs 100).. A much larger system for the simple reason that the BRI kept screwing up data and fax calls half way (even after many cabling changes and setup changes)

The 8MWSLI Card in the system in extensions 217-223 but the analogue phones connected will not "ring". You can dial from analogue equipment connected to the SLI extensions, but the phones don't ring when you call inbound.

ANy ideas? The system was only removed a few weeks back from an old company i worked for and the system definately was working fine.. Only difference is its been reset to factory defaults.

Also, If anyone knows the MMC to change the trunk and extnesion numbers I would be greatful. I can't find it in the manual, even thou I have changed it seeveral times in the past.

Just as a thought after reading up on some other posts, is it possible its a bad wiring of the TAIL? I had to wire the tail myself as they were cut, the way I have wired the tails is all the same and the tails are working on the DLI/ TRK/ BRI OK

Maybe the SLI does not use pin 1/26 , 2/27, 3/28 etc for SLI ??? Any ideas? Maybe someone knows the Pin outs for the SLI side of things, although I would assume its the same!!!

For changing trunk and extension numbers, go to mmc 724.

I figured out 724, very different to the old DCS 70.

However Im going to try playing with MMC 208 and 510 in regards to the lack of SLI ringing. Im guessing something may be bad in here.Any thoughts?

Are you sure the SLI ports are setup to ring?
Is this problem on incoming calls ,calls transferred to a SLI station or both?If it works fine on an internal call and you can transfer a call OK then you need to add the stations to the ring group for incoming calls.

No internal calls or the DID make the SLI's ring.. which is a problem for the fax machines. (They dont pick up)

Currently I have just hooked the fax up via an KBD_SLI on the back of the phone in the server room at the office which works fine.

Some background is, I have a Analogue phone hooked up to 224 currently, if i ring it from 201 (digital ext) the phone does not ring. If I answer the call on 224 (which is not rining) i get connected perfectly fine. (too bad i aint telepathic)

im guessing the voltages may be different due to it being a MW SLI and that i need to change it. I would even think i need an RGEN card, but this system used to have a fax machine hooked up to it and was working fine for several years.

Are you saying that the system you have now is a iDCS100 or Officeserv 100?In North America there is no 8MWSLI card just a 8SLI card.Did you move this card over from the other system?Maybe it's not compatible.

Its a "SAMSUNG DCS". Which I think is the equivalent to a DCS 200. THE 8MWSLI has always been in this system. The system has not been altered other than being moved abouot 10kM into my office.

The MW is just a Message Wait for SLI telephones with a MW lamp. Its more old school but hey. 

FYI - You can hear the rockers clicking in the SLI card when you dial the SLI extensions. the "click click click" etc as is normal. The card has no issue making outbound calls.

the click is normal.

have you checked the sli ring type? it should be set to CO ring. are you sure the phone you put on there works. I would put a test set on the pair and see if it rings.

My final thought is you have the pairs punched wrong but thats just a guess.

edited for spelling

The ring voltage would be generated onboard the card. Do any of the ports ring ok ?

Just for grins...
You said that the system was defaulted? How? If you didn't leave the slide switch in the off position on the processor for over 2 minutes, then you may have gliched the software. Default again, don't use MMC 811. If that don't fix it then I would remove the card via MMC 806 and re-install it. If that doesn't do it, then take it down to minimal config. That means remove all DLI, trunks and Sli except the card that is in trouble and test it. It's possible that the P/S is now bad because of the power removal and the load is too much. The cable should be fine becasue you were able to answer the call even tho it didn't ring. The key is that it doesn't ring either internal or external. Start looking backwards. :toast:

I agree with Rowlettdon about the power, I had this problem a few months ago and moved the 8MWSLI to another cabinet and it worked fine. power supply had to be replaced in the other cabinet.

OK, Figured it out seemingly!

I swapped the RGEN from Expansion into the KSU, it seems to have done the trick.. Bad RGEN!

However, I have learned an important lesson. The SLI cards in the DCS 200 are not as powerful as the DCS 70. The DCS 70 was able to drive the bells on an old Rotary phone I had.. the 200 doesn't.. Which made the process a lot harder.

For those who havn't played with the DCS200. The RGEN Is a circuit board located in the top of the KSU and Cabinets to step up voltage for SLI ringing. Apparently they do blow. This makes sense as the SLI card used to be in the other cabinet, I melted it all down into one cabinet as our 5 staff didn't really need a system with 56 DLI's and 8 SLIs with 14 TRK's, a PRI and 2 x BRI...Â

Approval for connection to the the Australian PSTN network requires that analogue phones use Sine wave ringing, and not square wave as is used elsewhere.

All Samsung equipment sold in Australia, (and I believe Italy) is supplied with modified ring generator circuits to meet this requirement.

This is one of the many regional difference between Samsung systems, and explains why some of the hardware and software is different bewteen countries.

Yes, I noticed on the KSU Logic board Jumper 1 and Jumper 2 (Hard wire joints) set to the sine wave. I noticed the rgen also has the ability for 20hz and 25hz with another 4 small adjustment knobs which I didn't have the nerve to play with in fear of blowing something up.

I've twice had a small card casino blow up the single lines on a 2x4 card by plugging too many phones on the circuit. They are intended to have ringing power for a little over one standard old Bell phone. You could talk, but no ringey dingey.
