I had a customer call in this morning telling me his SX-200 is dropping all calls (room to room and inbound/outbound). The calls all connect but drop after 3 to 30 seconds. He says the console isn't showing any alarms. He's 70 miles away and my Mitel tech is on his honeymoon (at 55 years old) in Austria of all places. Ideas on what the problem might be? I'll be heading out in the morning (booked solid with a man out for two weeks)and have plenty of equipment in stock. Just don't have time for 2 hours of troubleshooting. I've worked on the 20s and 50s years ago but I'm an ESI, Nortel, Avaya guy. I don't want to load a backup on another system and swap the whole cabinet if it's just a BCC or MCC.

Got to site early this morning the system was turned off and unplugged. I rebooted the system and watched for errors and alarms. NONE! System booted fine. I connected to the system checked the logs and other than a few minor alarms nothing. The system is currently functioning but I'm assuming it was a power supply issue??? I'm also assuming someone cleared the logs.

All calls being dropped usually indicates a common control problem such as a bay power supply, MCC or, more likely a flakey BCC-III card. How many bays comprise the system?

It's just a single bay. Just got off the phone with the customer it's started again. He said the BCC & MCC are now in alarm. The MCC is not showing any codes but it has rebooted twice.

since the rebooting twice are there any logs? Is the BCC a II or BCCIII?

I'm not currently on site. It's a BCC II

you can tell if you have remote access. MCC are normally fairly stable, maybe a BCC II or power supply.

My money would be on the BCC II.

Remember that, unlike station cards, the BCC is NOT, repeat NOT hot swappable.

Checked the logs they show "no alarm changed to minor alarm" and "MC restarted due to power up". Changed the BCCII now it (BCC) doesn't go into alarm but it still drops calls and the MCC shows alarm after it drops the first call. I took all the bay cards including ls/gs out and installed one at the time to see if it dropped station to station calls with just one card. It did. I'm leaning towards the MCC. Opinions???

You either have a bad MCC or a bad memory card. Call Resale Systems and talk to Fred.
