Private networking: MCDN over PRI and VoIP

The following describes how to network BCMs together in a private network using PRI lines with
MCDN protocol. When BCMs are networked with other call services, such as Meridian 1, using
the MCDN protocol, the network can also support centralized voice mail.
This chapter discusses MCDN networking based on North American trunks (PRI SL-1).
ETSI-QSIG private networking is configured very similarly, although network features may be
supported slightly differently.
The following describes the different aspects of MCDN private networking.
• "Using MCDN to network with a Meridian system" on page 297
• "Configuring fallback over a VoIP MCDN network" on page 311
• "Networking with ETSI QSIG" on page 313
Refer to "Private networking: Basic parameters" on page 315
directions for setting up non-PRI private networks.

Using MCDN to network with a Meridian system

When you connect your BCM systems through the MCDN protocol to a Meridian 1, the Meridian
system manages several aspects of the network, including voice mail, auto attendant services, and
system timing.
Programming note: For information about networking voice over IP (VoIP) trunks, which also
can be set to use MCDN. For networks running BCM 1.0 software or newer, the trunk protocol for
Meridian 1 IPT connection should be set to CSE.
The following information includes how to set up an MCDN network:
•

"Meridian system requirements"

• "MCDN networking checklist" on page 303
For an example of an MCDN system and the BCM programming to support it, refer to
example of a private network with Meridian 1" on page
Meridian system requirements
When setting up networking with Meridian, the Meridian systems must provide the following:
• provide the correct software version to allow MCDN features. If your Meridian system
administrator cannot confirm this, call your technical support center (TSC) or
1-800-4NORTEL.
