15. (continued).

If some of the nodes in a T1/E1 network have an NCM, and others do not as shown in Figure 7, the address Pass Setting will be set differently at some of the nodes. In Figure 7, nodes 1, 2 and 3 have NCM modules, and nodes 4 and 5 do not have NCM modules. This network requires that at nodes 1 and 2, SW7 is set as follows:

Place SW7-1 in the DOWN position

Place SW7-2 in the UP position

And at node 3, SW7 is set as follows:

Place SW7-1 in the UP position

Place SW7-2 in the DOWN position

Additionally all 5 nodes must have the CM setting UNIV = ON to enable the FDL path. This allows a user to “transparently” communicate to all nodes regardless of which node the PC is connected to. If the PC is connected to node 1, 2 or 3, a user can “talk to” nodes 1, 2 or 3 via the NCM path, and “talk to” nodes 4 and 5 over the FDL path. If the PC is connected to nodes 4 or 5, communication to all nodes is over FDL.
