I am a Mitel tech, but seldom work on this equipment, largely out of hotel service for a long long time. Never did support the SX200 LM, or better known as SX200 RM. Have limited time, and down customer really wanting to get something going. So I was sleuthing how the lines came into the system, and it appears they were pathed to slot 4, a ONS/CLASS LINE (12CCT) 9109-110-001-NA
My reaction is this card is repeatedly used through the system in a station application, not CO lines. Typical hotel, lots of analog motel phones.
Nearby are a couple LS/ GS cards, not installed, so did someone pull the card from other likely slot, number 8 that the cut amphenol cable would have routed to, and terminated in the LS/GS card. Then I need to find the documentation on that card, and set it up for CO loop start, not GS. The prior lines were coming in via internet, through an ADTRAN, then routed to the cut 50 pair line.
Since that occurence (the sabotage), the new carrier is a cable provider, and the lines would appear to be similar to the ADTRAN digital to analog modem lines from a local telecom provider. We are on Mediacom lines as of this week for first time. Medicom is a cable provider with faster internet and likely more stable than the small local internet provider who has been having many outages to many customers on a near constant basis these days. I think that pushed the client to switch.
In the detail on the Mitel SX200 LM documetation which is the book for the RM system, you find detail on the slot 4 of primary cabinet, which is where I found the term I asked about. Just need a weekend to bone up on this book, see if I can dig out the answer on how to configure the lines, and which card must be used for the incoming lines. When I tried a LS/GS card in card slot 8, I had a administrator error light. But no programming had been done. Customer indicates issues accessing anything from console as well. So we have just a few problems to solve.
I have to study the cabling more, maybe the console was on slot 4 on the ONS/ CLASS LINE card, and the CO lines came in on slot 8 to the LS/GS card. I know there is detail in that big manual on slot 4 regarding control of the system. All other cabling is intact, and all other amphenol cables are connected to the PBX.
