Nice find Andrew. There's even a defnintion for MGCP for it in CallManager 7.
Only problem is (where I agree with Thomas's design) is single point of failure. But so is his mux. Put the two 3845's in different locations and you have some distributed redundancy and no worries about digging up a fiber or yanking on the coax cables. Let the provider put thieir rack in your data center (fiber in) and run PRIs to your voice gateway or gateways. ________________________________ From: Thomas Koch [koch1...@comcast.net] Sent: Friday, September 25, 2009 4:18 PM To: 'Andrew Dorsett'; Michael Ciarfello Cc: ccie_voice@onlinestudylist.com Subject: RE: [OSL | CCIE_Voice] Choosing the right ISR?

Ok, so I am reviewing the interoperability guide and on page 15 I see that a 3845 can handle 450 DS0s (18.75 DS1s) at 75-percent platform CPU usage. However, isn't a T3 672 DS0s? If that's the case, I don't see any ISRs that should be able to support a T3. Of course, I think I'm wrong in that assumption because Cisco makes a T3/E3 NM and the website says that a 3845 can handle two of those modules. Thoughts? Thanks!
