SX2000 lines locking up

[AlfredSpecial]

I have an SX2000 light with analogue lines connected and sometimes all lines lock up after use and the system needs to be powered on and off to unlock them.

I have changed all kit and am still getting this problem

Any ideas?

thanks

AlfredSpecial,

Two questions - How often do you have to do this reboot, and by "lines" do you mean ONS/OPS line cards for standard telephones or LS/GS trunks?

Are you using auto attendant on these trunks?

Are you doing trunk to trunk transfer on these trunks?

 

[AlfredSpecial]

The trunks are LS and are directed to the reception console.

After a call the line will stay busy, this will then happen to all lines until they are all locked up and a system reboot is required to unlock them again.

Sometimes this happens after a few hours sometimes after a few months

First of all, make sure you have a *daily* programmed reboot or activity switch, depending on whether or not you have control redundancy. These switches need to have this done regularly, no fault of Mitel's, just the way things are. I've been there, done that, when I was just a Mitel Noob, my vendor's tech ("The Sexual Intellectual" - f***ing know-it-all, that is) neglected to program a daily reboot - drove me insane for three months with all sorts issues.

If you have a technician's handbook, run the healthy system checklist. If you don't have it, you can download a PDF from

It won't hurt to reset your LS/GS card, that can work minor miracles, especially if the switch or Per cabinet is not sited ideally (dirty environment, vibration, etc.).

Also it's most likely that you have ground start trunks, not loop start, as is the case in nearly every PBX. If there is a differential between system ground and telco ground the possibility that mayhem may ensue. Consult your vendor (Beware though: grounding is an issue among phone men that has launched a thousand fist fights and flame wars).

It's also not out of the realm of possibility that your LS trunks are out of spec. for current or induced AC. I suggest you look at the loop current and longitudinal imbalance bulletins on

http://www.sandman.com.

The methods for measuring this are outlined in the bulletin.

Hope this helps
