Question about Mitel Lands Phones

1 Answer

I have a mitel sx-50 console and an alarm keeps sounding which states EQP-BSY on the screen and when I press the alarm button it shows A11 0065 No Trunk Seize ACK. 09\01 on the screen. And it continues for a time and then it will stop no pattern to the alarm. Any ideas of what may be happening. Thank you. Cathy Tucumcari, NM

Mitel SX-50 System is not posting wakeup calls or smdr

Please refer to the user manual here

Also, try resetting the Mitel Server by powering off and back on; typically takes 5 minutes for the phones to come back on. If this doesn't work you may have a ONS Card that needs to be replaced; contact a service technician who can diagnose the issue.

Why my mitel sx-50 shows message on console no communication?

The phone line between the SX-50 console and the main control is disconnected or the console may need to be rebooted (unplug the phone line then reconnect it). If this doesn't solve it then contact your PBX system support person.

Printer queue is full on sx-50 attendant console

This is explained in the SX-50 system maintainer's handbook, 2 copies of which came with your SX-50 when it was new. However, this is a pretty old piece of phone equipment (30+ yrs) and when these systems were originally set up by outside service companies, it was not unusual for them to take the manuals so that customers would not be tempted to tamper and would call the service co instead. However, all is not lost. There is a very good Mitel support group on Tek-Tips ( On tek-tips the Mitel forum is under Home->Forums->Wiring Closet->Phone Systems->Mitel Networks Solutions Forum. You will need to register in order to post. Hope this helps.

My Mitel SX-50 dial pad on console does not work. Help

Look for a button on the console that is stuck down. This will cause the problem you are describing. If this is not the case, you need to get with a Mitel vendor to get the console repaired and refurbished.

We have an old mitel PABX console system with this info on the back: 9102-018-000-NA (serial #ACAAZ45-15). Don't have a manual and need one. Any ideas?

Well, you could just put that number in a search engine and get some pretty good hits. You would find that it belongs to an SX-20 Generic 500/503.

Now the tricky part. Perhaps a Mitel manual site?

SX-50 Attendant Console Failure

The console uses 3 pair USOC wiring from the console to the jack on the control card. Look at the Mitel provided cable from the console. It should be 6 pin and you can make sure the console is functional by moving it to the cabinet and plugging it in. If it works, you need to cable 432516 straight through on a 6-wire modular plug and terminate it in the same order on a jack where the console is. They must be paired for the long run.

I have a huge non-indexed pdf of an SX-50 if you need it. The console explanation is figure 5-14 of the -200 practice if you have it.

"Lock" display on console

Lock means lockout. If you've changed out the entire set to the cords, look for something in the wiring to be shorting out. You'll get that indication if you walk into a guest room and take the phone off the hook. It will alarm at the console and lock out.

Negative, the SX 50 does not support CID. You can upgrade the Mitel or use a CID Multi line interface to a PC. Here is one such model.

If you go to the bottom of the page on the right, click on how it works. Hope this hlpes.
