Configuring the public and private dialing plans 313
Programming Operations Guide
Using private network dialing
If your Business Communications Manager is part of a private network, you have a choice of
dialing plans. However, all Business Communications Managers on a network must use the same
type of dialing plan and have the same Private DN lengths to ensure proper call direction. Plan out
these settings before you start programming for the network.
• UDP plans use a routing code and a location code plus the set DN (i.e. 6-403-XXXX) to
determine where a call gets routed. You specify a Private DN length to allow all required digits
to be dialed. Each node on the network has a unique location code.
• CDP plans use a unique steering code that gets dialed as part of the set DN
(i.e. 2XXXX for one node, 3XXXX for another node, and so on) to determine where the call
gets routed. Since each node on the network has a unique code, no other routing is required.
• The Meridian system administrator generates the Private Network IDs. These IDs are unique
to each node on a network. Both UDP and CDP must include this code in programming.
Setting up the dialing plan
To set up a private network dialing plan, follow these steps:
1 Click the keys beside Services , Telephony Services , General Settings , and Dialing plan .
2
Click on Private network .
Note: When configuring a private network, ensure the numbering plan
does not conflict with the public telephone network. For example, in
North America, using “1” as an access code in a private network,
conflicts with the PSTN numbering plan for long distance calls.
