MCDN Private Networking
When you use MCDN on your private network, you gain the
advantages of being able to use a central voice mail/Auto
Attendant system to service the entire network, as well as
gaining advanced system network features, which keep
network traffic flowing along the most efficient paths.
MCDN networking uses PRI SL-1 lines and the MCDN
protocol firmware. You need keycodes for each of these
features.
To set up calling over an MCDN network, you define a dialing
plan that allows the user on any system to experience
consistent dialing strings for internal and external calls. For
this type of network, the DNs need to be the same length, but
they do not have to be unique to the entire network.
If your network is connected to a Meridian 1, and it is the
Meridian that you are using for centralized voice mail and
Auto Attendant, you can use either a UDP or CDP dialing
plan.
• If you use UDP, you dial a unique location code with the
local telephone DN range.
• In the case of CDP, the first digit of the DN range denotes
the node and is unique to each system.
However, if you are using a Norstar voice mail/Auto
Attendant for your centralized voice mail, you must create the
calling protocols on the network using CDP. This is a private
dialing plan where the first digit of the extensions for each
system is unique to that system, and all DNs on all systems are
the same length.
