System Networking

System Networking

In addition to public network connections, Business Communications Manager can be integrated into an existing private network of Meridian 1's or other PBX's to form a corporate telecommunications network. BCM's user interface looks and feels very much like Meridian 1, making it much easier to integrate small BCM sites into a large corporate network. All users interact with the system using the same familiar menus and tools.

CDN (Meridian Customer Defined Networking)
MCDN is a Nortel Networks proprietary ISDN-PRI signaling protocol used to interface one BCM to either another BCM, or a Meridian 1 system. MCDN is used to network voice switching capabilities only, and provides networking features such as Calling Party Name Display, Network Messaging Services and Message Waiting Indication. MCDN has been enhanced to enable networking with Voice over IP.

Voice over IP
With Voice over IP (VoIP) you can route voice calls between your sites over a Wide Area Network (WAN), so incurring no incremental cost for each call. If your sites are widely dispersed you'll quickly notice the benefit on your bottom line. Business Communications Manager uses advanced compression routing techniques to make effective use of capacity and deliver assured service quality.

SIG (Q reference point signaling)
QSIG is an ETSI standard signaling for multi-vendor peer-to-peer communications between PBXs and/or central offices. QSIG provides networking features such as Calling Party Name and Connected Party Name .

DPNSS (Digital Private Network Signaling System)
DPNSS is a networking protocol that gives operators access to Business Communications Manager features over multiple combined networks and is in use in a limited number of markets. Corporate offices, separated geographically, can be linked over DPNSS to other Business Communications Manager systems, bypassing the restrictions of the PSTNs to which they may be connected. This allows connected BCM systems to function like a private network. DPNSS networking supports the following features, 3 party conference, Send and Receive re-direction, Loop avoidance, Message Waiting indication, Executive intrusion, Call Diversion, Call offer and route optimization.
