External Network Element (ENE)—If selected, the CTC computer is only visible to the
ONS 15454 SDH to which the CTC computer is connected. The computer is not visible to the
DCC-connected nodes. In addition, firewall is enabled, which means that the node prevents IP traffic
from being routed between the DCC and the LAN port.
Gateway Network Element (GNE)—If selected, the CTC computer is visible to other
DCC-connected nodes. The node prevents IP traffic from being routed between the DCC and the
LAN port.
Proxy-only—If selected, the ONS 15454 SDH responds to CTC requests with a list of
DCC-connected nodes for which the node serves as a proxy. The CTC computer is visible to other
DCC-connected nodes. The node does not prevent traffic from being routed between the DCC and
LAN port.
