Yes I should have counted. I am a good legend/magix tech and made a rookie mistake. Now that we have spilt milk I am looking for some insite on recovering in this situation.

Client has a legend with (4) 408 cards, (1) 400 card, 2 T1 cards (used for network to two other legends), and added just recently a 3rd 100D for PRI.

This puts me over the 80 trunk limit and the switch only sees 12 of the line ports on the 3rd 100d.

Now that I am committed to the PRI I am considering pulling the 408's and putting in 008 MLX cards to recoup my trunk ports. We don't need all of them as we are adding this PRI, but I am concerned with "don't ever pull cards, or rearrange cards in a programmed system!"

Has anyone tried this and what were the pitfalls? I am hoping it will only mess up my tunk configs, meaning I will have to rebuild pools, T1's, and reassign private lines.

Any help appreciated.

By the way good see see Mr. Coale join the group. I took a class with you 3 to 5 years ago and have worked with you through Ben in FLA. This is a great group.
 
I had this problem and as long as you are only changing port positions in the trunking, you should be alright. The stations will lose centralized programming if you move their positions, so if you have a 408 card and you replace it with a 008 card , you should be fine. In my experience, you must print out all trunk positions and especially UDP routing after which of course noting which sets have any personal lines and such, you remove all lines from their associated postions and groups. then replace the cards and do a board renumber after it powers up., with printouts in hand, reprogram the line positions and you shopuld be fine. I would really backup to flash and on a seperate hard drive or disk before sattempting. I dsid do this to consiladate a switch with too many line ports and needed to add a PRI as well, it worked fine.
 
O.k.,here is the Deal with station when adding or removing cards. The station number follows the logical ID. The station translations(buttons,line assignments..ect) follow the slot/port assignment. For example, lets say slot 1 is a 408. slot 2 is a 408 and slot 3 is a 408. Now, you want to add a 016mlx to slot 2. That would mean that the first ext in slot 3 will now be located in slot 2 port 9. Yet, the translations will stay in s/p 03/01, so you would renumber 03/01 to be it's old ext number. This would require a dial plan printout. Same goes for the lines/trunks. In this case, you will be adding different lines to pools and redoing your T1 set-up. Are the 2 T's fractional. If you are you could move one of them to the back end, that way you wouldn't loose the abality for pots lines. As well, don't forget that your MOH and Paging are both through a trunk port. Hope this helps.
 
There is another sticky option, and it may or may not work for you. It requires the use of a multiplexer. First of all We'll assume that the two networked T-1's have data traveling on them as wella s the voice. Let's say, for example, that the two DS-1 cards used for networking use 12 Voice and 12 Data channels. You CAN split off the voice from each of the T's thereby giving 24 combined voice channels, and pass the combined channels as 24 channels of Voice to (1) ONE DS-1 card, giving you the ability to remove one of the DS-1 cards, and solving the issue. You cannot run PRI over the network this way, and there must be enough touce-tone receivers on the far end to handle the traffic.

Just remove all the trunk info and replace the 408 cards with 008 cards to keep the stations clean and then reprogram the lines. That's all I had to do and it worked fine, still running clean no errors for over a year.
 
Update:

Made the config change last night and all seems well. I spent the bulk of my time running reports and pulling backups just incase I needed to rebuilt or reload the system. Changed 408's into 008's made a handfull of programming changes and all seems good.

Here how it played out for those attempting in the future. config was 408, 408, 408, 100D, (+more) changed to 408, 008, 008, 100D, +. Trunk 808 was a private line on ext 150. After change trunk 808 (now the 4th port on the 100D) was still programmed as private line. This and a half dozen other minor changes needed to be made.
