programming a PRI

[brewerdude]

Can I build a trunk group and channels for a PRI without the actual card being in the PBX?

I'm doing some local service conversions, and the existing circuits are only regular T-1's and I don't have any spare 100D cards...

Do you have a spare processor & backplane?

If so, backup the current translations to your PC, and then set up the spare in surrogate mode.

You can do what you are trying to do in surrogate mode.

Trying to do it to a live system, on a non-exitant module could be problematic, especially when you try to move things around after taking out the existing T1 card.

Also, sometmes, after doing SURROGATE PRI, I have had to tell it "switch type" again, once we go live.

Darn. the only spare processor and backplane I have is an R3. :-(

what is the quickest way to convert from a T-1 to a PRI (seeing as I don't have a spare system to work on).

We tried doing a conversion last Friday, but had to bail out as the PBX wasn't cooperating, and we ran out of time.

I thinking about putting a new card in the PBX and programming the T-1 ahead of time, but won't I have issues with renumbering afterwards??

Well, there is no "QUICKEST WAY".

It doesn't take all that long, but while you are doing it, the system is DOWN!

Not to mention, if things do not go right, you are sunk.

And, in answer to your question of renumbering afterwards, I eluded to that earlier.

1 thing you may want to try is:

Add a 2nd card, set it up with your existing programming and then try to program the PRI to the original card.

Lucky me, I have enough equipment around to program such things in SURROGATE and then just upload the new translations.

Make sure you remove all programming pertaining to the t1 before you change it to pri. If you don't it seems it doesn't want to come up, or you have strange problems.

Having a spare slot and an extra 100D does make things much easier to convert from a T1 config to a PRI config. This way you can keep the customer up and running while you setup and test the PRI before allowing traffic on it. That is how I did my first PRI cutover. But you need to plan all the steps and have a cooperative service provider.

If you want to read posts about that, search back to DEC2005/Jan2006 time in the archives.

Hope this helps!
