The eNodeIV device is a more complex connector because is connects two different protocols
and also connects the protocols at different layers. On the IP side the eNodeIV device operates
at the application layer and so is appropriately called an IP Gateway. On the 709.1 side the
eNodeIV device operates at the network layer and is appropriately called a 709.1 router. So
depending on the user’s perspective the eNodeIV could be called a gateway or router or a
router/gateway. (See Figure 1.3)

The eNodeIV device also employs a web server for configuration purposes. (See Figure 1.4)
