Linking MICS 7.1 to MICS 7.1 1

[Phonehed]

I have a customer that may eventually be a good candidate for a direct link between two full blown, MICS systems in the same building. I hate last minute surprises so I wanted to run this by the top contributing Norstar gurus here just to see how practical that's really gonna be and wondering if anyone can think of any good reason(s) not to do it?

I'm pretty sure the two systems would be less than 325 feet apart so I'm thinkin' with an extra DTI card in each system and a long patch cord between them, I could create a universal coordinated dialing plan and provide a fairly seamless interface.

The voice mail is the part I'm concerned about and they'd rather not have two voice mail systems. I'm sure each system will need some 200 plus mailboxes so even the CP-150 is way too small.

As I recall there is a way to use a Mod Plus (NAM) as a centralized voice mail system but not sure if that's a very viable option or if it's a seamless interface where all the feature codes work normally. Not real crazy about those hard drive based vmail systems either.

I'd be real interested in hearing from anyone who may have done this before or anyone who is maintaining systems that are already successfully and seamlessly linked together like this.

you're on the right track for linking the two mics ksu's via DTI's and long cat 5 patch cord.. see Centralized VoiceMail faq799-5317 for NAM programming.

Just to add,
Along with the DTI cards you'll need PRI & MCDN Keycode for each system.
You can use Feature codes to access the NAM on the system that is connected but the other system can not. You'll actualy dial the NAM Pilot DN.

If the length turns out to be too great you can install a repeater between them. I believe you'll be ok unless you exceed 700 feet. The 325 limitation is Ethernet and doesn't apply to T1.

Iy may be more economical to upgrade to a BCM450 and use a FEM so you can reuse your existing sets and modules. One system, one dialplan, one messaging system.

If it means they 'll have to have two voice mail systems they're probably not gonna go for it.

Thanks for the info though!

Don't know how many ext you have on the 2 system but you mite look at just using one system as for the site to site I have 2 MICS over 5000 ft apart and using 2 smart jack that I cond the local phone guy out of for repairers T1 on 22 awg can be up to 6000ft leaves at 0 db should arrive at under 35 db If you can use one system look at MKS stuff it would be better than running all that copper. you can run phone up to 4000 ft with out power supply from the KSU with out them giving you trouble. with the mcdn code the system are almost seamless as for voice mail each system will have to retain it on v mail but you can send mail, caller ID, page, call park and pickup from one system to the other
