Private networking: MCDN over PRI and VoIP
This following describes how to network BCMs together in a private network using PRI or VoIP
lines with MCDN protocol.
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 section describe the different aspects of MCDN private networking.
• “Using MCDN to network with a Meridian system” on page 335
• “Configuring fallback over a VoIP MCDN network” on page 348
• “Networking with ETSI QSIG” on page 350
Refer to “Private networking: Basic parameters” on page 355 for general requirements and
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 3.6 software or later, the trunk protocol for
Meridian 1 IPT connection should be set to CSE.
This section includes the follow information about setting up an MCDN network:
• “Meridian system requirements”
• “MCDN networking checklist” on page 340
For an example of an MCDN system and the BCM programming to support it, refer to “An
example of a private network with Meridian 1” on page 345.
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.
The Meridian must provide the following:
— end-to-end signaling (option 10)
— message center (option 46) and an IVMS link (option 35)
