Advanced Private Networking
There are two ways of setting up dialing plans for an
Advanced Private Network (APN).
•
The first method uses routing tables to interconnected
systems. This type of network may use SL-1 lines, but it
does not use the MCDN protocol, even though the MCDN
keycode is required to allow the use of PRI SL-1 lines.
•
The second method allows you to network among other
Norstar systems, Meridian systems, and Business
Communications Manager systems using SL-1 lines and
the MCDN protocol. This system uses the private dialing
plans in the same way as the Private Network Tandem
Calling network does. However, if you are using a Norstar
to support your central voice mail or call attendant, you
must use a CDP dialing plan. The MCDN protocol
provides additional features that support the central voice
mail/Auto Attendant as well as system call routing.
Networking using routing codes
If you have a simple private network, composed of one central
Meridian 1 and two smaller sites with Norstar systems, you
can use routing codes to direct calls. The following example
shows a Meridian 1, representing the head office, connected to
several smaller branch offices.
In this network, only the head office has trunks connected to
the public network. The branch offices access the public
network via the private connection to the head office. This
configuration allows for cost savings by consolidating the
public access trunks. Users at all three locations access the
public network by dialing 9, followed by the public number.
