FTE Device Index Addressing
The rotary BCD switches that set the FTE device index are located on the EHPM FTE Interface
assembly. These switches set the FTE Device index which is used as the lowest octet of the IP Address.
See figure Figure 80 - EHPM FTE Interface Module
The PDTag of the EHPPM or ENIM is the node type plus the UCN index. The FTE annunciation
message contains the PDTag which includes the UCN Address, the IP Address in use, and the FTE
Device Index. This provides all of the information required for address resolution for EUCN
connections.
