Installing And Using System-To-System Networking
•
Network Properties—Use this menu's entries to enable or disable the hub operation. Since the hub controls
the system-to-system networkings of the nodes, the system grants each node access to a particular block of
intercom numbers (also referred to as extension numbers) through the hub database.
•
Network Disable Status: Enable or disable the network database status as a hub.
•
Network Extension Length: Set the extension length for the hub and each node's stations to be either
three or four digits.
•
Node Configuration—Use this menu's entries to define the hub and the nodes that the network will use.
•
Enabled: Enable or disable the hub at each node for networking operation.
•
Node ID: Every node or hub system in the network requires an identification number (0–999).
• Node Name: Name the hub and each node with an alpha-numeric name of up to 32 characters.
•
Node System Type: Define the system type for the hub and each node.
•
Network Links—The entries on this menu allow you to program the physical links between the hub and the
nodes.
• Modify Links: This entry selects all valid board slots that can accept DXNET or FXNET interface boards
for network linking, and adds or removes board slots in a preselected node. There can be several links
between the hub and a node with a maximum of 10 links allowed.
•
Extension Provisioning—This screen allows the system to provide intercom numbers for validation and
routing purposes and allow you to assign these numbers to a node or remove numbers that you have previously
assigned.
NOTE: This screen only maps the allowed numbers. You must use intercom number programming at the hub and
each node to actually assign station names and port numbers to intercom numbers. Further, to insure that
the network feature operates properly, you must assign unique extension numbers at each system. For
example, assign 1000 series intercom numbers at the hub, 2000 series numbers at node one, 3000 series at
node two, 4000 series at node three, and so forth. While the intercom numbers can be three or four digits
in length, you must use the same digit length throughout the networked systems.
Arranging For Line Pooling
•
Program the link channels for each node into their own line group. Be sure to isolate the link channels from any
other lines that may be connected to the local system. Remember, several board slots at the hub may be
dedicated to the same node depending upon the number of links required to handle the call traffic. The system
will not allow you to mix network channels and non-channel lines in the same line group.
•
Program the line groups that contain network channels into ARS route tables in the same manner as you would
program any normal line group into the ARS tables.
•
Perform all necessary ARS programming at the hub and at each node.
