Turn Up a DWDM Node

This chapter explains how to provision a single Cisco ONS 15454 dense wavelength division multiplexing (DWDM) or a single hybrid (TDM and DWDM) node and turn it up for service, including node name, date and time, timing references, network attributes such as IP address and default router, users and user security, card installation, and DWDM connections.

Note Procedures in this chapter require Cisco MetroPlanner, a DWDM planning tool provided to you by your Cisco account representative. You enter your DWDN network topology and traffic requirements into MetroPlanner. MetroPlanner prepares a shelf plan for each network node and calculates the power and attenuation levels for the DWDM cards installed in the node. For information about Cisco MetroPlanner, contact your Cisco account representative.

Before You Begin

Step 3 Click the Maintenance tab.

Step 4 Verify that the ALS Command is set to OSRI off.

Step 5 From the ALS Mode drop-down menu, choose Disable. Click Apply.

Step 6 Click the Provisioning > Optical Line tabs.

Step 7 For the TX (transmit) port entry, verify that the value in the Power column falls within the following ranges:

•For OSCM cards installed on nodes set to Control Gain, the power should be -5 dBm.

•For OSC-CSM card installed on nodes set to Control Gain, the power should be a minimum of -6 dBm on OADM nodes.

•For OSC-CSM cards installed on nodes configured as a passive or active OADM nodes, the power level depends on the Pout OADM Stage power level on the WDM-ANS > Provisioning tab:

–If the Pout OADM Stage value is less than -6.5 dBm +/- 0.5 dBm, the OSC-CSM power should be equal to that power.

–If the Pout OADM Stage value is greater than -6.5 dBm +/- 0.5 dBm, the OSC-CSM power should be -6.5 dBm +/- 0.5 dBm.

•For OSC-CSM cards installed on hybrid nodes, the Pout-osc should be:

–-5.0 dBm if the DWDM system type is Control Gain and

–-1.5 dBm if the DWDM system type is Control Power.

Step 8 If the OSCM or OSC-CSM power levels are not within the ranges specified in Step 7, complete the following steps. Otherwise, continue with Step 9.

a. Click the Maintenance > ALS tabs. Verify that OSRI is set to off and ALS Mode is set to Disable.

b. Clean the optical connections. See the "NTP-A112 Clean Fiber Connectors" procedure on page 17-21.

Step 1 Complete the "DLP-A60 Log into CTC" task at the node where you want to provision the DWDM cable connections. If you are already logged in, continue with Step 2.

Step 2 From the View menu, choose Go to Network View.

Step 3 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the "DLP-A227 Disable Alarm Filtering" task as necessary.

b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide for procedures.

Step 4 In node view, click the Provisioning > WDM-ANS > Port Status tabs. Verify that all links have a Regulated status. If any links say Not Regulated, click Launch ANS.

Step 5 On one side of the node, either east or west (if the node is a terminal, the terminal side), create a physical loop back on the OPT BST by using a patch cord with 10 dB bulk attenuators to connect the card's Line-TX port with Line-RX port.

Step 6 On the OSCM card, verify that the OSC link becomes active. (OSC Termination must already be provisioned, see the "DLP-A342 Provision OSC Terminations" task.)

Note The OSC signal loop back might cause an SDCC Termination Failure alarm.

Step 7 Tune the tunable laser on the first wavelength (1530.33 nm) of the 100Ghz ITU-T grid and connect it to the CHAN RX 01 port on the 32 MUX-O card using the available patch-panel.

Step 8 Double-click the west or east 32 MUX-O card on the shelf graphic to open card view.

Step 9 Click the Provisioning > Optical Chn > Parameters tabs.

Step 10 Set the port #1 status to OOS_MT. This puts the port Out Of Service, but enables VOA provisioning.

Step 11 Verify that the Port 1 power level reaches the provisioned set point (VOA Power Ref).

Note Output power that is lower than the specified value might keep the 32 MUX-O card from reaching the provisioned set point.

Step 12 Verify that the west or east OPT BST card is working properly:

a. In node view, double-click the west or east OPT-BST card to open card view.

b. Click the Maintenance > ALS tabs.

c. Verify that the laser status is set to On. If so, continue with Step 13. If not, continue with Substep d.

d. Verify that the ALS Command is set to OSRI Off (optical safety remote interlock is not enabled).

e. If the ALS Command is set to OSRI On, choose OSRI Off. Click Apply.

f. Check the Laser Status. If it is not set to On, replace the card. See the "A242 Install the DWDM Cards" procedure.

Note On Provisioning > Opt.Ampli.Line> Parameters tab, the power value on port #6 reaches the provisioned set point = +2 dBm. However, the actual value reported by CTC also includes the ASE power contribution, so the value is always greater than +2 dBm (Power Ref).

Note When Laser Status is off, the Port #2 power is lower than or equal to -1 dBm as shown. This value is not a significant optical power and must be ignored.

Step 13 Verify that the west or east OPT-PRE card is working properly:

a. Display the west or east OPT-PRE card in card view (double-click the card on the shelf graphic).

b. Click the Maintenance > ALS tab.

c. Verify that the Laser Status is ON.

Note On Provisioning > Opt.Ampli.Line > Parameters tab, the power value on port #6 reaches the provisioned set point = +2 dBm. However, the actual value reported by CTC also includes the ASE power contribution, so the value is always greater than +2 dBm (Power Ref).

d. Click the Provisioning > Optical Line > Parameters tabs.

e. Verify that the DCU IL (insertion loss) value is less than or equal to 10 dB.

Note When Laser Status is off, the Port #2 power is lower or equal to -1 dBm is shown. This value is not a significant optical power and must be ignored.

Step 14 Verify the west or east 32 DMX-O in card view:

a. Display the east or west 32 DMX-O card in card view.

b. Click the Provisioning > Optical Chn > Parameters tabs,

c. Set the status of port #1 to OOS_MT.

d. Check that the Power value on part #1 reaches the provisioned set point (VOA Power Ref).

e. (optional) Connect a power meter to the CHAN TX 01 port through the patch-panel. Verify that the physical optical power value coming out of drop port #1 on the west 32 DMX-O card is consistent with the value read (the maximum allowed error is +/-0.5 dBm).

Step 15 Restore the default OOS status on the 32 MUX-O card port that was set to OOS_MT in Step 10.

Step 16 Restore the default OOS status on the 32 DMX-O card port that was set to OOS_MT in Step 14.

Step 17 Launch ANS to restore the correct node configuration.

Step 18 Repeat Steps 7 through 17 for the remaining 32 wavelengths of the 100 Ghz grid to verify the correct behavior of all VOAs inside the 32 MUX-O and 32 DMX-O cards.

Step 19 If the node is a hub node, repeat Steps 5 through 18. If it is a terminal node, continue with Step 20.

Step 20 Remove the loopbacks.

Step 21 Restore the default OOS status on all ports previously set to OOS_MT and launch ANS to recover the correct node configuration.

Step 22 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the "DLP-A227 Disable Alarm Filtering" task as necessary.

b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide for procedures.

Pdrop

Sets the east-side expected drop power level on the client interface. Pdrop is the power level of each channel after it is demultiplexed. The power is then sent to the client.

-14 dBm

-50 dBm to 30 dBm

Pexpress

Sets the east-side expected per-channel power on the pass-through interface.

-12 dBm

-50 dBm to 30 dBm

Pout-mux Stage

Sets the per-channel output power at the multiplexing stage. Pout-mux is the power that is sent to the multiplexer after the power from the client transmitters is gathered. The VOAs keep the power sent to the multiplexer at a constant level.

-18 dBm

-50 dBm to 30 dBm
