Networking with Norstar There are a number of ways you can network Norstar systems together, or network Norstar systems with other Nortel systems into private networks. What types of lines you use to perform the networking will determine the type of services that can be shared between systems. Keep in mind that each node (Norstar system) is considered an external system by every other node within the network, even though, to the users, it appears to be all one system. This affects how you configure call transfer and call out features on each system. On the home node, all features are configured as local numbers. On all other nodes, all features directed to the home node are configured with external numbers. As well, each node must have a unique identifying code. What this code will be, and how it is configured for the user, depends on what type of trunks and dialing rules you choose to use. If the network has a Meridian as part of the network, the Meridian administrator will determine identification codes for the systems. This section describes various configurations of private networks. The general settings that are required to set up the home node for each system are provided to give you a sense of what is required for each type of network. The common goal is to provide the user with the sense that the network is one large system that provides common access to colleagues in other buildings, cities, or countries. In some systems they may need to enter a destination code before the local number to route the call to the correct system. In other systems, using a common dialing plan allows users to dial colleagues at any location simply by entering the same number of digits they would use to dial a colleague at the next desk.
