| Junior Member | Capacity Question I have a big site up here, we are doing a major upgrade to IP and qmaster. I have a question on the capacities outlined in the system manual. The table doesnt make much sense to me like most of the nec manuals. It states on the table for 3400 or later that u can have a max of 1020 LT, IP and PS ports. Then its subdivided to 512 LT ports and 956 IP ports. The site im upgrading has apporximately 400 virtuals programmed. It has a massive call centre and most of these are CTI queues for q master. It has approx 200 LTs attached already. They currnetly have a nortel system which we are gonna change out to all IP handsets off the NEC. The total amount is in the 300 area. I dont have exact numbers on me at the moment. So my question is has anyone ever exceeded these capacities. Does the system allow for the exceeded number to be programmed and then only assign the amount of Time slots it has available? Or will I get a hardware error in moc mode when I try to program past the number. SO if the capacity of IP and Virtual extensions is 956 I should be ok in this area with the amount of virtuals and IP handsets I have? Last thing I need is this to stuff up on a cutover. I will be loading some scripts shortly and dont wanna kill any virtuals either while this call centre is running. |

| Senior Member | Virtuals don't enter the formula so just don't count them. The capacity of the system relates to the number of handsets it can actually drive so that is IP and legacy. Virtuals can appear on these but don't take up system capacity. There is a somewhat complicated capacity list in the system manual which shows 512 for legacy and 956 for IP but then gives a figure of 1020 as the max combined so you should be OK but for peace of mind you would be best off consulting with TAC (Technical assistance centre) or whatever the UK version is. There is a limit to the number of virtuals you can have and that is 1000 (000 to 999) however as I said before I don't believe these count in working out the capacity. The thing that causes a lot of confusion is that we have always had Virtual extensions but then when they brought in IP they coined the phrase Virtual pim, it would have been better if they had used something like Phantom pim as we have been using the phantom term down here for years to describe programming extensions in pims that aren't physically present. |

| Junior Member | Na R4 im from Aus aswell. In sydney actually. In regards to virtuals. I had heard from not positively reliable sources that virtual extensions and IP extensions eat into the same memory areas on the cpu. If u are certain this isnt true i will take your word for it though. |

| Junior Member | Not totally sure what is happening here in terms of what you have now and what you are moving to. Everything seems ok but don't forget the manual is giving you theoretical maximums. Your main limiting factor is a max of 8 Physical PIMS (at main site) and 8 IP pads. Don't forget just because IP Terminals use virtual PIM's doesn't mean they will not require space in Physical PIM's for IP Pads to do the the IP-TDM translation. Also are there any other cards that will require wireable slots that will further reduce your capacity? It pays to plan ahead. You should know when you upgrade exactly what your capacity for future growth is. |

| Junior Member | Hey R4 I found this in the R12 Bus Features manual. Under Software Line Appearance. The system can support up to 512 Dterms, up to 956 IP Enabled Dterm and up to 1020 SOFTWARE LINE APPEARANCE. However, the combined total of Dterms, IP Enabled Dterm and SOFTWARE LINE APPEARANCES must not exceed 1020. (Series 3400 software enhancement) |

| Senior Member | Thing is you can have virtuals that don't appear anywhere like pilot numbers, the question would be where do those come into it and also if a number appears on 5 phones is that 1 line appearance or 5? Now about the meaning of life the universe and everything........ 42, I know |
