Turn Up a Network
This chapter explains how to turn up and test a Cisco ONS 15454 dense wavelength division multiplexing (DWDM) network. For DWDM topology reference information and span loss tables, refer to the "Network Reference" chapter in the Cisco ONS 15454 DWDM Reference Manual.
There are two main DWDM network types: metro core, where the channel power is equalized and dispersion compensation is applied, and metro access, where the channels are not equalized and dispersion compensation is not applied. The DWDM network topologies supported are hubbed rings, multihubbed rings, meshed rings, linear configurations, and single-span links. The DWDM node types supported are hub, terminal, optical add/drop multiplexing (OADM), reconfigurable optical add/drop multiplexing (ROADM), anti-amplified spontaneous emissions (anti-ASE), and line amplifier. For DWDM and hybrid node turn-up procedures, see Chapter 3, "Turn Up a Node."
Note 
Unless otherwise specified, "ONS 15454" refers to both ANSI and ETSI shelf assemblies.

Step 1 In node view (single-node mode) or shelf view (multishelf mode), click the Provisioning > Timing > General tabs.
Step 2 In the General Timing area, complete the following information:
•Timing Mode—Choose External if the ONS 15454 derives its timing from a building integrated timing supply (BITS) source wired to the backplane pins (ANSI) or a MIC-C/T/P front mount electrical connection (FMEC) (ETSI); choose Line if timing is derived from an OSC-CSM or OSCM card that is optically connected to the timing node. A third option, Mixed, allows you to set external and line timing references.
Note Because Mixed timing might cause timing loops, Cisco does not recommend its use. Use this mode with care.
•SSM Message Set—For DWDM nodes, choose the Generation 2 synchronization status messaging (SSM) option. Generation 1 is used only by SONET or SDH ONS 15454s that are connected to equipment that does not support Generation 2. See the "Timing Reference" chapter in the Cisco ONS 15454 DWDM Reference Manual for more information about SSM, including definitions of the SONET timing levels.
•Quality of RES—Sets the timing quality for the user-defined, reserved (RES) S1 byte if your timing sources supports RES. Most timing sources do not use RES. If it does not support RES, choose RES=DUS (do not use for timing reference). Qualities are displayed in descending quality order as ranges. For example, in Generation 1 SSM, ST3<RES<ST2 means that the timing reference RES is higher than a Stratum 3 (ST3) and lower than a Stratum 2 (ST2).
•Revertive—Select this check box if you want the ONS 15454 to revert to a primary reference source after the conditions that caused it to switch to a secondary timing reference are corrected.
•Reversion Time—If Revertive is checked, choose the amount of time that the ONS 15454 will wait before reverting to its primary timing source. Five minutes is the default.
Step 3 In the Reference Lists area, complete the following information:
Note You can define up to three timing references for the node and up to six BITS Out references. BITS Out references define the timing references used by equipment that can be attached to the node's BITS Out pins on the backplane (ANSI) or FMEC (ETSI). If you attach equipment to BITS Out pins, you normally attach it to a node with Line mode, because equipment near the external timing reference can be directly wired to the reference.
•NE Reference—Allows you to define three timing references (Ref 1, Ref 2, Ref 3). The node uses Reference 1 unless a failure occurs to that reference, in which case the node uses Reference 2. If Reference 2 fails, the node uses Reference 3, which is typically set to Internal Clock. Reference 3 is the Stratum 3 clock provided on the TCC2/TCC2P card. The options displayed depend on the Timing Mode setting.
–If the Timing Mode is set to External, your options are BITS-1, BITS-2, and Internal Clock.
–If the Timing Mode is set to Line, your options are the node's working OSCM cards, OSC-CSM cards, transponder (TXP) cards, muxponder (MXP) cards, and Internal Clock. Choose the cards/ports that are directly or indirectly connected to the node wired to the BITS source. Set Reference 1 to the card that is closest to the BITS source. For example, if Slot 5 is connected to the node wired to the BITS source, choose Slot 5 as Reference 1.
–If the Timing Mode is set to Mixed, both BITS references and OSC, TXP, or MXP cards are available, allowing you to set a mixture of external BITS clocks and OSC, TXP, or MXP cards as timing references.
•BITS-1 Out/BITS-2 Out—Sets the timing references for equipment wired to the BITS Out backplane (ANSI) or FMEC (ETSI) pins. BITS-1 Out and BITS-2 Out are enabled when BITS-1 Out and BITS-2 Out facilities are put in service. If Timing Mode is set to external, choose the OSC, TXP, or MXP card used to set the timing. If Timing Mode is set to Line, you can choose an OSC, TXP, or MXP card or choose NE Reference to have the BITS-1 Out and/or BITS-2 Out follow the same timing references as the network element (NE).
Note All TXP or MXP card client ports are available for timing regardless of the card's termination mode. TXP or MXP trunk ports can be a timing reference when ITU-T G.709 is set to OFF and the Termination Mode is set to LINE.
Step 4 Click Apply.
Step 5 Click the BITS Facilities tab.
Note The BITS Facilities section sets the parameters for your BITS-1 and BITS-2 timing references. Many of these settings are determined by the timing source manufacturer. If equipment is timed through BITS Out, you can set timing parameters to meet the requirements of the equipment.
Step 6 In the BITS In area, complete the following information:
•Facility Type—(TCC2P card only) Choose the BITS signal type supported by your BITS clock, either DS1 or 64Khz+8Khz.
•BITS In State—If Timing Mode is set to External or Mixed, set the BITS In State for BITS-1 and/or BITS-2 to IS (in service) depending whether one or both BITS input pin pairs on the MIC are connected to the external timing source. If Timing Mode is set to Line, set the BITS In State to OOS (out of service).
Step 7 If BITS In State is set to OOS, continue with Step 8. If the BITS In State is set to IS, complete the following information:
•Coding—Choose the coding used by your BITS reference, either B8ZS (binary 8-zero substitution) or AMI (alternate mark inversion).
•Framing—Choose the framing used by your BITS reference, either ESF (Extended Super Frame) or SF (D4) (Super Frame).
•Sync Messaging—Check this check box to enable SSM. SSM is not available if Framing is set to Super Frame.
•Admin SSM—If the Sync Messaging check box is not checked, you can choose the SSM Generation 2 type from the drop-down list. Choices are PRS (Primary reference source; Stratum 1), ST2 (Stratum 2), TNC (Transit Node Clock), ST3E (Stratum 3E), ST3 (Stratum 3), SMC (SONET minimum clock), and ST4 (Stratum 4).
Step 8 In the BITS Out area, complete the following information, as needed:
•Facility Type—(TCC2P only) Choose the BITS Out signal type, either DS1 or 64Khz+8Khz.
•BITS Out State—If equipment is connected to the node's BITS output pins on the backplane and you want to time the equipment from a node reference, set the BITS Out State for BITS-1 and/or BITS-2 to IS, depending on which BITS Out pins are used for the external equipment. If equipment is not attached to the BITS output pins, set the BITS Out State to OOS.
Step 9 If the BITS Out State is set to OOS, continue with Step 10. If BITS Out State is set to IS, complete the following information:
•Coding—Choose the coding used by your BITS reference, either B8ZS or AMI.
•Framing—Choose the framing used by your BITS reference, either ESF or SF (D4).
•AIS Threshold—If SSM is disabled or Super Frame is used, choose the quality level where a node sends an alarm indication signal (AIS) from the BITS 1 Out and BITS 2 Out backplane pins. An AIS alarm is raised when the optical source for the BITS reference falls to or below the SSM quality level defined in this field.
•LBO—If an external device is connected to the BITS Out pins, sets the line build-out (LBO) distance between the ONS 15454 and an external device. If an external device is connected to BITS Out, choose the distance between the device and the ONS 15454. Options are: 0-133 ft. (default), 134-266 ft., 267-399 ft., 400-533 ft., and 534-655 ft. Line build out (LBO) relates to the BITS cable length. If an external device is not connected to BITS Out, leave this field set to the default.
Step 10 Click Apply.
Note Refer to the Cisco ONS 15454 DWDM Troubleshooting Guide for timing-related alarms.

d. Perform a short-term BER test using a test signal from a test set or protocol analyzer.
e. Monitor the payload performance monitoring (PM) for at least 10 minutes for errors.
Note To see an accurate PM count, the BER test results must be consistent with the transmitted bit rate for at least 10 minutes.
Note For information about using a test set or protocol analyzer, refer to the test set or protocol analyzer user guide.
Step 15 Display the next node in the circuit path identified in Step 8 in node view.
Step 16 Repeat Steps 9 through 14 for the node.
Step 17 Repeat Steps 15 and 16 for all nodes on the circuit path identified in Step 8. Complete the steps for the circuit destination node last.
Step 18 Switch to network view and click the Circuits tab.
Step 19 Create a new OCHNC or OCHCC circuit for the next ITU wavelength listed in the Traffic Matrix report using one of the following procedures:
• NTP-G151 Create and Delete Optical Channel Client Connections, page 7-2
• NTP-G150 Upgrade Optical Channel Network Connections to Optical Channel Client Connections, page 7-15
Step 20 After the circuit status is DISCOVERED and its state is IS, click it and then click Edit.
Step 21 In the Edit Circuit dialog box, click the State tab.
Step 22 In the Cross-Connections table, record all the nodes that appear in the Node column. These are the nodes that are in the circuit path. The first node is the circuit source, and the last node is the circuit destination.
Step 23 Complete Steps 9 through 14 for nodes in Step 22 that:
•Are not part of the circuit created in Step 4.
•Are the circuit source or destination and the circuit created in Step 4 did not originate or terminate on the same side (west or east).
For all the remaining nodes, no further checks are needed.
Step 24 Repeat Steps 9 through 23 for all OCHCC or OCHNC circuits listed in your Traffic Matrix report. If a node fails any test, verify the setup and configuration and then repeat the test. If the test fails again, refer to the next level of support.
After all tests are successfully completed and no alarms exist in the network, the network is ready for service.
Stop. You have completed this procedure.

Step 1 Complete the "DLP-G46 Log into CTC" task at an ONS 15454 on the network.
Step 2 Using an optical spectrum analyzer, check the received OSNR for each transmitted channel on both ends of the span. Identify the last OSC-CSM, OPT-PRE, or OPT-BST MON port that the channel passes through before it is dropped. If OPT-PRE cards are installed with an OPT-BST, OPT-BST-E, or OSC-CSM card, use the OPT-PRE MON port.
Note For OSNR values for each card class, refer to the "Card Reference" chapter in the Cisco ONS 15454 DWDM Reference Manual.
Step 3 If the OSNR is too low, check the following, depending on your node configuration:
Note The purpose of this step is not to improve the signal-to-noise ratio (SNR), but to match the per-channel power level within the RX port power range.
•Check the fiber connections between the OPT-BST, OPT-BST-E, or OSC-CSM card and the OPT-PRE amplifier. If needed, clean the connectors. See the "NTP-G115 Clean Fiber Connectors" procedure on page 13-25.
•On the near-end OPT-BST amplifier, check the equalization of the added channels at the monitor output.
•On the OPT-PRE amplifier, check the output power on both COM TX and DC TX ports.
•On the far-end OPT-PRE amplifier, check the amplifier gain tilt at the monitor output.
If the OSNR is still too low, contact your next level of support.
Step 4 Repeat Steps 2 and 3 for all traffic in the network.
Stop. You have completed this procedure.
NTP-G142 Perform a Protection Switch Test
Purpose
|
This procedure tests the optical path, client TXPs, MXPs, and Y-cable protection groups in your system for proper operation. The test signals can be generated by either the actual client device or a test set, whichever is available. Cisco recommends that you repeat this test at each node in the network where protection group traffic is dropped.

Step 1 Complete the "DLP-G46 Log into CTC" task at an ONS 15454 on the network.
Step 2 Identify the Y-cable circuit to be tested by viewing the Traffic Matrix for your site. Locate the TXPs/MXPs in the ONS 15454 node that will be used for the protection group.
Step 3 Verify that the Y-cable protection group is provisioned:
a. In node view (single-node mode) or multishelf view (multishelf mode), click the Provisioning > Protection tabs.
b. In the Protect and Working areas, confirm that the correct TXPs/MXPs are in the Y-cable protection group by viewing the slot number and card type.
c. If the required protection group is not provisioned, stop and perform the "G33 Create a Y-Cable Protection Group" procedure. Otherwise continue with Step 4.
Step 4 Repeat Step 3 for each Y-cable protection group at this node. When all protection groups are verified, proceed to Step 5.
Step 5 Physically connect the transmitter of the client or test set to either Port 10 or Port 12 of the Y-cable module protecting the circuit under test. (See Table 3-3 on page 3-77 and Table 3-4 on page 3-77.)
Step 6 If you connected the transmitter to Port 10, connect the client or test set receiver to Port 5 on the Y-cable module. If not, connect the client or test set receiver to Port 11 of the Y-cable module.
Step 7 At the far-end site for the circuit under test, physically loop the Y-cable module as follows:
a. If this is the first client on the Y-cable module, loop Port 10 to Port 5 on the far-end Y-cable module.
b. If this is the second client on the Y-cable module, loop Ports 11 and 12 on the far-end Y-cable module.
Step 8 At the near-end site for the circuit under test, place the client device or test set into service and begin transmitting the required payload.
Step 9 In CTC, display the near-end site in node view (single-node mode) or multishelf view (multishelf mode).
Step 10 Click the Maintenance > Protection tabs ( Figure 6-2).
Figure 6-2 Maintenance > Protection Tabs
Step 11 In the Protection Groups area, highlight the protection group to be tested.
Step 12 In the Selected Group area, identify the slot that is Active and the slot that is Standby.
Step 13 Verify that the LED display on the physical cards in the shelf match the following:
a. For the Active TXP/MXP card, record the slot number: _____. Verify that the port LEDs are as follows:
–DWDM port is green.
–Client port is green.
b. For the Standby TXP/MXP card, record the slot number: _____. Verify that the port LEDs are as follows:
–DWDM port is green.
–Client port is not illuminated or amber, depending on the TXP/MXP card.
Step 14 In the Selected Group area, highlight the active TXP/MXP slot.
Step 15 From the Switch Commands area below the Selected Group area, click Manual, then click YES.
Step 16 From the Selected Group area, record the following information and verify that the active and standby TXP/MXP slot numbers are the opposite of Step 13.
a. For the Active TXP/MXP card, record the slot number: _____. Verify that the port LEDs are as follows:
–DWDM port is green.
–Client port is green.
b. For the Standby TXP/MXP card, record the slot number: _____. Verify that the port LEDs are as follows:
–DWDM port is green.
–Client port is not illuminated or amber, depending on the TXP/MXP card.
Step 17 Verify that the LED displays on the physical cards in the shelf match the following:
a. For the Active TXP/MXP slot LEDs:
–DWDM port is green.
–Client port is green.
b. For the Standby TXP/MXP slot LEDs:
–DWDM port is green.
–Client port is not illuminated.
Step 18 Confirm that the client or test set at the local site is operating normally with no alarms. If the test set is reporting active alarms, contact your next level of support.
Note It is normal to see a traffic hit on the test set during a protection switch.
Step 19 From the Switch Commands area below the Selected Group area, click Clear, then click YES to return the protection group to the original state.
Step 20 Repeat Steps 5 through 19 for each protection group at your site.
Stop. You have completed this procedure.
