Is there any technical limitation to a BCM50 w/ a DSM32 and 4x16 MBMs? With the base unit I would have 60 digital extensions (they need about 48) and 8 analog trunks (they have 5 - but may expand to 7 or 8).
Seems like it should work, is there anything I'm missing?
Thanks for the help!

Jeremy,
I believe you would have to use IP sets to get to where you want/need to be. You can have a max of 44 digital phones and then add up to 32 IP sets. In your scenerio, looks like they would have to go with 4 IP sets to get to 48 total phones.

VAND: Don't forget that you can now get an 8x16 module. If you had a 32+DSM and an 8x16, that would give you 12x60
Trunks 4 + 0 + 8 = 12 Stations 12 + 32 + 16 = 60
And IP after that.
If CON is the opposite of PRO Then what is the opposite of Progress?

I was under the impression that 44 was the maximum number of digital stations on the BCM 50?

That was my question exactly NTlayoff - I didn't need an 8X16 - was just looking at the 4x16 - but my boss said it is maxed at 44 extensions.
I can see the thought of the phone to trunk ratio being low - but that is fine in my application. I just wasn't sure if there is a built in limiter. Looking under resources in Element Manager, seems like it should work fine to do a DSM32 and a 4(or 8) x 16 module.

Ok let's set the record straight.
Digital sets = 44 (there is a limit even though you can put two expansion cabs on you can only use one DSM32) Analog Caller ID POTS Telephone Lines = 12 (4 main + 8 expansion) PRI = 1 (Drops POTS to 4 max) IP phones = 32 Analog Phones = 4 IP Trunks = 12

So it looks like you have to go IP to make the 60 phones...or move to a BCM200 or 450. Great info Marv! Steve

There is still some debate going as to whether 44 really is the limit. Stay tuned. If someone has access to BCM50 could you count the number of DNs available in Telephony Resourses > Digital Sets > Active and Inactive

Marv, Under Telephony | Sets | All DNs - there are a total of 76 digit set DNs. 12 on the main bus (port 401-412) and 16 on each additional bus (2 bus' per expansion cabinet). Port 501-516/601-616 for exp cab 1 and 701-716/801-816 for exp cab 2. That's why I think it would work to go over 44 digital - but I don't have the hardware to test, and no clients want to buy it just to see if it will work. If it doesn't work - it has to be due to a self imposed limit by Nortel. Also - under Application Resources it shows the system max Digital Trunks as 2. So I'm assuming the BCM50 does support a DTM in both expansion cabinets - so I don't see why it wouldn't support 2 DSM32's. Anyone able to test?
