Chapter 5 Turn Up a Network
NTP- D344 Open-Ended SNCP Acceptance Test
Step 5 On the network map, double-click the node that you logged into in Step 1.
Step 6 Create a test circuit from that node to the STM-N trunk (span) cards on the nodes that connect to the
third-party network. For example, in Figure 5-11 on page 5-35, a circuit is created from Node 1 to the
Slot 5 STM-N card at Node 2, and a secondary circuit destination is created on the Slot 12 STM-N card
at Node 3. For circuit creation procedures, complete one of the following:
• For VC4 circuits, complete the “NTP-D323 Create an Automatically Routed High-Order Circuit”
procedure on page 6-55. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
• For VC3 circuits, complete the “NTP-D54 Create an Automatically Routed Low-Order VC3
Circuit” procedure on page 6-31. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
• For VC12 circuits, complete the “NTP-D81 Create an Automatically Routed Low-Order VC12
Circuit” procedure on page 6-19. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
• For VC11 circuits, complete the “NTP-D334 Create an Automatically Routed Low-Order VC11
Circuit” procedure on page 6-7. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
Step 7 Create a circuit within the third-party network from ONS 15454 SDH connection ports to the second set
of ONS 15454 SDH connection ports on both SNCP spans. Refer to the third-party equipment
documentation for circuit creation procedures.
Step 8 Repeat Step 6 to create a second circuit at the terminating node on the other side of the third-party
network. In Figure 5-11, this is Node 6. However, this circuit will have two sources, one at
Node 4/Slot 12, and one at Node 5/Slot 5. The destination will be a drop card on Node 6.
Step 9 Configure the test set for the test circuit type you created:
• VC4 or VC4-nc—If you are testing a VC4 circuit or a VC4-nc circuit on an STM-N card, you must
have a direct optical interface into the ONS 15454 SDH. Set the test set for STM-N. For information
about configuring your test set, consult your test set user guide.
• VC3—If you are testing a clear channel E3/DS3I, you must have a patch panel or a direct E3/DS3I
interface into the ONS 15454 SDH. Set the test set for clear channel E3/DS3I. For information about
configuring your test set, consult your test set user guide.
• VC12—If you are testing an E1, you must have a patch panel or a direct E1 interface to the
ONS 15454 SDH. Set the test set for E1. For information about configuring your test set, consult
your test set user guide.
• VC11—If you are testing a VC11 circuit on an STM-N or MRC-12 card, you must have a direct
optical interface to the ONS 15454 SDH. Set the test set for STM-N. For information about
configuring your test set, consult your test set user guide.
Step 10 Verify the integrity of all patch cables that will be used in this test by connecting one end to the test set
transmit (Tx) connector and the other end to the test set receive (Rx) connector. If the test set does not
run error-free, check the cable for damage and check the test set to make sure it is set up correctly before
continuing.
Step 11 Create a physical loopback at the circuit destination card:
a. Attach one end of a patch cable to the destination port’s transmit (Tx) connector.
b. Attach the other end to the port’s receive (Rx) connector.
Step 12 At the circuit source card:
a. Connect the transmit (Tx) connector of the test set to the circuit receive (Rx) connector.
