Nodes Support - Mitel Inter-Tel 5000 Installation And Maintenance Manual

99 Nodes Support

Version 2.1 or later software allows Inter-Tel Advanced Communications Platforms to expand to
99-node networks in the United States and European markets. Each node can transparently
interconnect to 98 other systems using T1/E1/PRI networking and IP networking.
With the 99 Nodes feature the increased network capacity does not affect endpoint user
features. Endpoint users can still dial an extension of a remote user, and the system will
transparently route the call throughout the network. From an administrative perspective, you
must consider the following issues as the node capacity increases:

For information about programming 99 nodes, refer to the Inter-Tel 5000 Features and
Programming Guide (part no. 580.8006).

Database Management: To program the 99 Nodes feature, you must log-in to individual
systems to configure them. You must plan for supporting a 99-node network by devising a
numbering plan scheme for each node. You should be aware that the creation of new
devices automatically causes the system to export extensions to the network. The use of
export/import may take longer if you attempt to export/import with all 98 remote nodes.
Numbering Plan: The system supports extensions with a maximum of five digits. It is
important to design a network numbering plan that can support all devices in the network.
DB Programming Export/Import: Creation of new devices on any node of a network
automatically causes the system to export extensions across the network. Once network
established, you can use DB Programming to adjust node parameters, including the import
or export of devices. Because of the potential complexity of managing a network with
numerous nodes and devices, it is essential that the system administrator devise a
network numbering scheme that accommodates all 99 nodes.
Networking Resources (IP and PRI): You must be aware of the Primary Rate Interface
(PRI) and Voice over IP (VoIP) resources required to maintain a 99-node network. For
VoIP resources, all nodes must have the appropriate IP bandwidth to support the
maximum IP networking calls.
o T1/E1/PRI Networking: Networking across T1/E1/PRI remains the same as in previous
versions, except for the increased node capacity. With appropriate licensing, in the T1/
E1/PRI field in DB Programming, you can number network nodes from 1 to 99.
o IP Networking: IP Networking functionality remains the same as in previous versions,
except for the increased node capacity. If a device does not have an IP resource
reserved, the system dynamically allocates one from the pool of available IP
resources.
OAI Applications: To support more than 63 nodes, a new version of the CT Gateway
Server is required. Performance degradation may occur on the CT Gateway and individual
nodes depending on the number of OAI applications that connect to the CT Gateway. If
many OAI applications are connected directly to an individual node, slowdowns on those
nodes may occur.
The CT Gateway Server must meet Inter-Tel's performance requirement
when it is attached to a 99-node network. When configuring a 99-node
network, this could increase the OAI data by 50%. For example, the
Attendant Console application requires a large amount of data at power-up.
Multiple Attendant Console applications, along with fully populated nodes,
could increase OAI data by 50% during the Attendant Console power-up
sequence.
