OK, well it has a main bay and an expansion bay.
Both have white front covers and I suppose the closest appliance would be a microwave. So it looks like two white microwaves.

As for storage, the main bay has a card in a slot next to the PSU which has a memory card sticking out of it that looks like a PCMCIA flash drive. It may not be PCMCIA, but the form factor is pretty close. The Flash card is labelled SX200 LWN (at least that's what I think it says, it's hard to read the card as most of it's behind the smoked plastic front of the card and the letters LWN are in a silly stylized font that runs the W and the N together.

I was always told it was an analog system. Though it has digital phones I didn't think this was related. My understanding was that digital referred to the ability to interface with digital trunks like ISDN etc.

Nothing is labeled on the system itself and there are no real manuals with it. Just for the console and basic voice mail operation etc.

So I've been looking through different documents and it seems like we have 1 SX-200 ELx cabinet and 1 peripheral cabinet (which looks identical to the main cabinet, but with less connectors on the back).

Sorry for the confusion and newbie mistakes, but I've been thrown in the deep end on this project. I'm doing my best to learn what I need to know but the curve is steep and sometimes being an IT guy works against you as it predisposes you to make assumptions about how something works that might not be true.

Ok, you have the ML/EL series. T1 is usable with one PCB that goes in slot 10 or 11, 5 or 6 must be empty. Depending on what release of software you have, ISDN is also possible. I think johnp can address that much better than I, never have installed an ISDN on a Mitel. john? John C.

Well, since we are all analogue here, I've already gone that route. I'm actually not having any trouble with the Mitel yet. But talking to the telco trunks is flaky. Once I get all my lines wired, I'm going to run the line impedance matching on all the lines and hopefully that will sort it out.

While I'm finding out all about our Mitel, is there any way to tell what type of signalling option our DID lines are using by looking at the Mitel DID cards?

What I mean is, we have analogue DID, but I don't know if our telco uses wink start or what to signal the PBX with the DID extension.

Anyway, thanks for all the great feedback and help.

I'll have to do some time in the computer forums and try and contribute back.

BTW, the card that has the Flash card in it is labeled

The way to tell how the DID is setup is by viewing the programming forms 13 and 15. If you don't have access, another method would be to use a butt set with a polarity light attached to the circuit. If when going off-hook on the butt set, the polarity light comes on for a second and goes off. Then you are set for wink. If the light stays off then it's likely immediate start. If the light stays on all the time, you leads are reversed, immediate start. I'll let you figure out what happens if the leads are reversed and it's set for wink.

Now you know how we feel, and a lot of us have been feeling that way for years smile Seems that either the Mitel is toning out before your box is ready, or your box is toning out before the co is.

To verify where the problem is, connect a test set on the input to your box and dial a local number. If it fails, your box is likely the problem. I find it hard to believe that the Mitel isn't providing all digits. You may need a pause before dialing, I've had to do that on some 3300's when they dialed before the co was ready.

johnp,

I'm pretty certain there's nothing wrong with the Mitel. My box gets and interprets the tones from the Mitel just fine. I can even see in the logs where it picks up, and interprets the correct numbers from the tones. It's when the box tries to dial out on the CO lines where I'm having trouble.

Hopefully this week I'll get my connectors in (back ordered)and get all my cables built and I'll be able to run impedance matching on all the lines and get it sorted out with that.

If that doesn't do, I'll try some other ideas.

Thanks.

My approach would have been to connect to the voip unit via T1 and change the routing in the Mitel to use a list for LD dialing, with first choice thru voip, then via local pots. I would have only setup enough channels on the T1 tie that the voip box could handle.

Kind of a kiss approach, but it's scalable.
