This could take some time....

How many boxes (PIMs) does your system consist of? This will tell us whether you can expand the system or not in legacy equipment. Do not count the boxes that only contain batteries. if the answer is 8 then your vendor is possibly correct.

If your system is an IVS2 or IPS then eight circuits per card is the norm however some cards can have only 4 circuits. the question of how many cards per box depends on the system type and also can depend on the type of cards fitted. For example an IP Pad card is only one card but takes up 30 time slots so effectively half a PIM. Cards in the system are dedicated not hybrid so a digital card will only drive Dterms and an analogue card will only drive analogues.

The easiest way to swap extensions is at the punch down blocks.

No the punch down blocks are more like a patch panel. The pabx is a switch

Slow down----It's not all that confusing....

Let's start out...what kind of switch do you have? Judging by you saying only IP phones are left, I'm guessing a 2000 IPS.

Some simple questions for the beginner....

How many cabinets do you have? Each cabinet holds physically 64 ports. The average cabinet holds 8 cards x 8 ports per card. But there are exceptions.

There are actually 3 types of phones:
Analogs-those plain push-button phones. They take an analog line card.
Digital-that's those nice display and speaker phones NEC calls Dterms.
IP-they look a like digital Dterms but have a RJ-45 jack in the back for a CAT-5 cable.
#1 rule--do not attach analog cards to digital phones or vice-versa.

If you have less than 8 physical cabinets, you can add another cabinet if you want to add more hard-wired (legacy) phones. But if you've maxed out the physical capacity of the switch, all you may have left are IP's. You didn't give any details here.

To move phone, there's several ways to do it. Some are easy...some are hard. The hardware way, have an electrician, or someone who knows how to punch down wires, move the cablles to the phone jacks at the blocks.

Or if you're confident with your commands, you can move the extension with the programming.

Or better yet---during the installation, I had punch down panels of all the extensions installed. All the extensions come out at cat-5 panels. I have them labeled with the extension numbers down the row. When someone moves, I move the cat-5 jumpers to their phone jacks from one port to the other. Click-click-and I'm done in seconds. Even our NEC vendor and techs think that's the smartest way to go. It cost us about a $1000 more during installation, but down the road, I don't have any service calls to move phone jacks.

Give some more details please...

10 lines x 300 phone sets is an odd config. Are you sure there's not a T-1 or PRI circuit hideing in there somewhere?

If you only have 300 stations then you should be able to add more TDM (non-IP) phone sets. It may require add'l equipment or even a software licence upgrade, but this is normal.

can you get us a bay face layout of your system? (what cards are in which slots of which cabinets) Software levels and CPU versions would be helpful as well.

At first glance I would say you should be able to add TDM sets, ok.

Yes it is a NEC IVS2000. There are four cabinets - there is a battery on the floor connected to this system but not a battery in each cabinet. There is a T1 card in this system to connect our other location which our data and phone travel over.

How do I determine where an extension is at on the punchdown? I read somewhere in another posting look up the LEN through Matworx? I figured that out and get the LEN but what do I do with that number? Is that the number on the punchdown where it's connected?

I took some pictures of our system here's the link:

Any Help you can give me is greatly appreciated. Thanks again. I upped the pics but had to resize them. If they aren't big enough you can find them on photobucket under IAServerJockey or email me and I can email them to you.

Ok firstly you used to have an IVS 2000 but from what has been said and from the photographic evidence it has been retrofitted to an IPS The two cat5 cables are a dead giveaway as is the suggestion you use IP extensions. The reason the vendor is saying IP in future is probably because of the existing IVS configuration and it may well be possible that they can't buy new boxes (PIMs) to add on to the system. However these will be readily available on the second hand market. You can add up to 4 more physical PIMs You may also find you need to source some of the cards from second hand stock as well. I for one have never seen IPS PIMs added to a retrofit system, I don't know if it is possible, perhaps someone else knows the answer to that?

The record book for your punch down blocks should have the Len positions written in but if the records are missing you will have to create your own. To do this you need to determine where the system tails (those three thick cables coming off the bottom of each PIM) terminate. Usually ther all terminate in order but if any of the boxes are later additions they may be elsewhere. Having found them len 000 is on the first pair and they count upwards from there. Just to complicate matters every 25th pair is not used so you skip 25, 50, 75, 100 etc. The first 75 pairs are PIM 0 and count from 000 to 063 at which point you stop counting and go to pair 75 and start counting again starting at 100 and going up to 163 again you stop and jump to pair 151 and start at 200. And so on till you have all the lens listed. From then on once you have a len number you will know exactly where to find it on the punch down blocks.

The picture tells me you have 3 slots free in your top PIM. That should be able to accommodate 3 4 cct extension cards for 12 extensions without adding an extra pim.

Watch out if you try to use the pim on the left, it looks as though that is where your IP-PAD is fitted and even though it is one card it uses half the box
