Cisco ONS 15454 SDH Installation and Operations Guide, R3.3
May 2002
Chapter 9 Ethernet Operation
G1000-4 Circuit Configurations
Step 10 Click Next.
The Circuit Creation (Destination) dialog box opens.
Step 11 Choose the circuit destination from the Node menu.
Step 12 From the Slot menu choose the slot that holds the G1000-4 card that you will use for the other end of
the point-to-point circuit.
Step 13 From the Port menu choose a port.
Step 14 Click Next.
The Circuit Creation (Circuit Routing Preferences) dialog box opens.
Step 15 Confirm that the following information about the point-to-point circuit is correct:
Circuit name
Circuit type
Circuit size
ONS 15454 SDH nodes included in the circuit
Step 16 Click Finish.
Step 17 If you have not already provisioned the Ethernet card, follow the Provision G1000-4 Ethernet Ports
procedure on page 9-7.
Note To change the capacity of a G1000-4 point-to-point circuit, you must delete the original circuit and
reprovision a new larger circuit.
9.5.2 G1000-4 Manual Cross-Connects
ONS 15454 SDHs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet
circuits. When other vendors equipment sits between ONS 15454 SDHs, OSI/TARP-based equipment
does not allow tunneling of the ONS 15454 SDH TCP/IP-based DCC. To circumvent a lack of
continuous DCC, the Ethernet circuit must be manually cross connected to a VC-4 channel riding
through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node while
utilizing the non-ONS network.
Note In this chapter, cross-connect and circuit have the following meanings: Cross-connect refers to
the connections that occur within a single ONS 15454 SDH to allow a circuit to enter and exit an
ONS 15454 SDH. Circuit refers to the series of connections from a traffic source (where traffic enters
the ONS 15454 SDH network) to the drop or destination (where traffic exits an ONS 15454 SDH
network).
