13.2.1 Scenario 1: CTC and ONS 15454 SDH Nodes on Same Subnet
Note The ONS 15454 secure mode option is available when TCC2P cards are installed. Secure mode allows
two IP addresses to be provisioned for the node, one for the MIC-C/T/P LAN port and one for the TCC2P
DCC interfaces. Secure mode IP addressing is described in the “13.2.9 Scenario 9: IP Addressing with
Secure Mode Enabled” section on page 13-20. IP addresses shown in the other scenarios assume secure
mode is not enabled or, if enabled, the IP addresses shown in the examples apply to the MIC-C/T/P LAN
port.
13.2.1 Scenario 1: CTC and ONS 15454 SDH Nodes on Same Subnet
Scenario 1 shows a basic ONS 15454 SDH LAN configuration (Figure 13-1). The ONS 15454 SDH
nodes and CTC computer reside on the same subnet. All ONS 15454 SDH nodes connect to LAN A and
all ONS 15454 SDH nodes have DCC connections.

13.2.2 Scenario 2: CTC and ONS 15454 SDH Nodes Connected to a Router
In Scenario 2 the CTC computer resides on a subnet (192.168.1.0) and attaches to LAN A (Figure 13-2).
The ONS 15454 SDH nodes reside on a different subnet (192.168.2.0) and attach to LAN B. A router
connects LAN A to LAN B. The IP address of router interface A is set to LAN A (192.168.1.1), and the
IP address of router interface B is set to LAN B (192.168.2.1).
