Using SL-1 with MCDN to network with a Meridian system
When you connect your Business Communications Manager systems through the SL-1 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, refer to the IP Telephony Configuration Guide. For networks running
Business Communications Manager BCM 3.5 software or newer, 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 538
An example of an MCDN system and the Business Communications Manager programming to
support it, is given in
Meridian system requirements
When setting up networking with Meridian, the Meridian systems must provide the following:
•
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)
— Meridian Mail link (option 77 and 85)
— basic Attendant Console Directory features (options 40, 45, and 83)
— ISDN PRI or ISDN Signaling link (option 145 and 146 or 145 and 147)
— advanced ISDN features (option 148)
— network message services (option 175)
•
act as the timing master for the private network connections
•
use descending mode for PRI B-channel selection
•
recognize dial codes for all nodes in the network.
•
provide routing tables that direct incoming calls to the correct nodes on the network, including
DID calls from the public network
•
recognize the destination code (usually 9) that indicates a public network call, regardless of
where in the network the number was dialed from.
