22.2.9 Scenario 9: IP Addressing with Secure Mode Enabled
TCC2P cards provide a secure mode option allowing you to provision two IP addresses for the
ONS 15454. One IP address is provisioned for the ONS 15454 backplane LAN port. The other IP address
is provisioned for the TCC2P TCP/IP craft port. The two IP addresses provide an additional layer of
separation between the craft access port and the ONS 15454 LAN. If secure mode is enabled, the IP
addresses provisioned for the TCC2P TCP/IP ports must follow general IP addressing guidelines. In
addition, TCC2P IP addresses must reside on a different subnet from the ONS 15454 backplane port and
ONS 15454 default router IP addresses.
The IP address assigned to the backplane LAN port becomes a private address, which is used to connect
the ONS 15454 GNE to an OSS (Operations Support System) through a central office LAN or private
enterprise network. In secure mode, the backplane's LAN IP address is not displayed on the CTC node
view or to a technician directly connected to the node by default. This default can be changed to allow
the backplane IP address to be viewed on CTC only by a Superuser.
