DDI MUX on BCM 400 4.0?

[BCM400Guy]

I recently purchased a DDI MUX MBM in the hopes that it will work on BCM 400 4.0 that I am building for second location. This MBM does not function in my BCM50 (as far as I Know.... I tried.) that we have and so far seems to behave O.K. in BCM400 4.0. (No red flashing lights like on BCM50) Not fully tested because I am awaiting T1 Connection. My question is will this MBM replace my DTI MBM or not? Also how many DS30 allocations will it use? (I hope to be using the right terminology). I would like the luxury of sharing the T1 line between voice and data but I can't find any info on DDI MUX after BCM 2.5
Any help would be helpful. Thanx in Advance.

It's now called the DDIM.
Found this in the Install Guide.


Digital drop and insert MUX
The digital drop and insert MUX media bay module (DDIM) enables a BCM system to share its
connection to a universal T1 network with a local area network (LAN) to provide a combination of
voice and data channels. Enables a BCM system to share its connection to a universal T1 network with a LAN.
• provides the functionality of a DTM (T1 digital lines only)
• splits the incoming T1 line so that some of the lines are used for voice traffic and some of the
lines are used for data traffic
• provides either the channel service unit (CSU) or data service unit (DSU) functionality to support connections to data terminal equipment (DTE), such as a router or a bridge
• connects to network devices that support V.35 interfaces
• provides end-to-end transparent bit service
• supports loopbacks between the BCM system and the internal BCM components, and between the BCM system and digital terminal equipment.

Thanks Superdude for the info. My questions remain. Will this DDI MUX MBM operate in my BCM400 4.0? And how many DS channels (buses) will it use? I Know older MBM's sometimes reserve more buses to do the same job i.e. EE-DS32 MBM VS DS32+. Again this is very new to me. I hope someone can help shed some light on this.

DDIM will run in a BCM 200/400. It uses two DS-30 loops. I only used one once several years ago. From what I remember you can't do fractional PRI with it. If you use PRI, all 24 channels need to be enabled. If you're using a DTI/E&M T-1 you'll be fine.
