APPENDICES
6.9 To prevent circular or excessive routes, the system limits the number of “hops.” A call
or communication can take up to 10 hops to other nodes. (However, 2-3 hops maximum is rec-
ommended.) Using the sample shown on the previous page, here is an example of a call that
makes three hops through intermediate nodes to reach its destination (the path is also shown in
the diagram below):
1. A call is placed from Node 1 to Node 4.
2. Node 1 first attempts to route through Node Trunk Group 97502, but that route is not
available. So Node 1 routes the call using Node Trunk Group 97501 and uses Nodes 2
and 3 as intermediate nodes.
3. Because the network has already routed the call through Node 1, Node 2 will not use
Node Trunk Group 97501 and routes the call through its Node Trunk Group 97502.
4. Node 3 routes the call through its Node Trunk Group 97502 to Node 4. (It will not use
97501 because the call came from Node 2.)
6.10 Determining in what order to list the Node Trunk Groups in a Node and when to use
Linear or Distributed search type depends on the system configuration and traffic.
