Turn Up Network

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

This chapter explains how to turn up and test Cisco ONS 15454s network, including point-to-point networks, linear add drop multiplexers (ADMs), path protection configurations, and bidirectional line switched rings (BLSRs).

Step 1 Display the node (login) view.

Step 2 On the shelf graphic, double-click the card with the port(s) you want to put in or out of service. The card view appears.

Step 3 Click the Provisioning > Line tabs.

Step 4 Under State, choose one of the following:

•IS—The port is in-service.

•OOS—The port is out-of-service. Traffic is not passed on the port until the service state is changed to IS, OOS_MT, or OOS_AINS.

•OOS_MT—The port is in a maintenance state. The maintenance state does not interrupt traffic flow, alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. Use OOS_MT for testing or to suppress alarms temporarily. Change the state to IS, OOS, or OOS_AINS when testing is complete.

•OOS_AINS—The port is in an auto-inservice state; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether their alarms are reported or not, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

Step 5 If you set State to OOS-AINS, set the soak period time in the AINS Soak field. This is the amount of time that the state will stay in OOS-AINS state after the signal is continuously received.

Step 6 Click Apply.

Step 7 As needed, repeat this task for each port.

Step 8 Return to your originating procedure (NTP).

NTP-A40 Provision BLSR Nodes


Purpose	This procedure provisions ONS 15454 nodes for a bidirectional line switched ring (BLSR).
Tools/Equipment	None
Prerequisite Procedures	35 Verify Node Turn Up
Required/As Needed	As needed
Onsite/Remote	Onsite
Security Level	Provisioning or higher

Step 1 Complete the "DLP-A44 Install Fiber-Optic Cables for BLSR Configurations" task on page 2-32, verifying that the following rules are observed:

•Verify that the east port at one node is connected to the west port on an adjacent node, and this east to west port connection is used at all BLSR nodes, similar to Figure 5-2. In the figure, the OC-N drop card on the left side of the shelf is the west port, and the drop card on the right side of the shelf is considered the east port.

•For four-fiber BLSRs, verify that the same east port to west port connection is used for the working and protect fibers, similar to Figure 5-3. Verify that the working and protect card connections are not mixed. The working cards are the cards where you will provision the DCC terminations.

Figure 5-2 Four-Node, Two-Fiber BLSR Fiber Connection Example

Figure 5-3 Four-Node, Four-Fiber BLSR Fiber Connection Example

Step 2 Log into an ONS 15454 that you want to configure in a BLSR. See the "DLP-A60 Log into CTC" task on page 3-23 for instructions. If you are already logged in, continue with Step 3.

Step 3 Complete the "DLP-A253 Provision SONET DCC Terminations" task. Provision the two ports/cards that will serve as the BLSR ports at the node. For four-fiber BLSRs, provision the DCC terminations on the OC-N cards that will carry the working traffic, but do not provision DCCs on the protect cards.

Note If an ONS 15454 is not connected to a corporate LAN, DCC provisioning must be performed through a direct (craft) connection to the node. Remote provisioning is possible only after all nodes in the network have DCC provisioned to in-service OC-N ports.

Step 4 For four-fiber BLSRs, complete the "DLP-A214 Change the Service State for a Port" task to put the protect OC-N cards/ports in service.

Step 5 If a BLSR span passes through third-party equipment that cannot transparently transport the K3 byte, complete the "DLP-A89 Remap the K3 Byte" task. This task is not necessary for most users.

Step 6 Repeat Steps 2 through 4 at each node that will be in the BLSR. Verify that the EOC (DCC Termination Failure) and LOS (Loss of Signal) are cleared after DCCs are provisioned on all nodes in the ring.

Step 7 Complete the "126 Create a BLSR" procedure.

Stop. You have completed this procedure.

DLP-A89 Remap the K3 Byte


Purpose	Use this task to provision the K3 byte. Do not remap the K3 byte unless specifically required to run an ONS 15454 BLSR through third-party equipment. This task is unnecessary for most users.
Tools/Equipment	OC48AS cards must be installed on the BLSR span that you will remap.
Prerequisite Procedures	DLP-A60 Log into CTC, page 3-23
Required/As Needed	As needed
Onsite/Remote	Onsite
