    Optical Services

    An optical service provides optical (wavelength) connectivity between optical service endpoints. An optical service endpoint can be a transponder interface that connects to the optical network or it can be an optical port on equipment within the optical network.

    PSM allows users to manage optical services in a BTI7000 or BTI7800 optical network.

    In a BTI7000 optical network, the transponder interface endpoints can be BTI7800 UFM interfaces or select interfaces on MX Series or PTX Series routers or QFX Series switches.

    In a BTI7800 optical network, the transponder interface endpoints can be BTI7800 UFM interfaces only.

    Visualizing an Optical Service

    PSM allows users several ways to visualize an optical service. An optical service can be visualized at the network, service, group, and module levels. Service paths can be highlighted and detailed information can be displayed through tool tips or in table form. The examples in this section are taken from a BTI7000 DOL service.

    1. To see a summary of an optical service, hover over the service in the Network tree under the Optical branch.
    2. To see an optical service in its own panel, select it in the Network tree under the Optical branch.

      PSM displays the network elements that this service spans along with the service endpoints indicating the endpoint ports and wavelength.

      If the service endpoint has a Remote ID configured, the Remote ID is shown in parentheses.

      If the service includes a split ROADM node, the link connecting the two network elements comprising the ROADM node is shown with a icon. For example, in the following figure, 10.1.220.33 and 10.1.220.37 are both part of a single ROADM node, with each NE providing a degree:

      For more information on how PSM recognizes split ROADM nodes on BTI7000 network elements, see Configuring a split ROADM node. .

      For more information on how PSM recognizes split ROADM nodes on BTI7800 network elements, see Adding a fiber connection on a ROADM or an ILA client port.

      Note: If this is your first time visualizing this service, you will see the administratively-defined default layout if it exists. If a default layout does not exist for this service, then you will see the layout that PSM automatically generates. See 13.

      Note: If this is your second or subsequent time visualizing this service, you will see the layout that existed when you last exited this service view.

    3. To see a complete service view, right-click the background and select Show All Topology .

    4. To see a service path:
      1. Right-click the endpoint and select Highlight Service.

        Only groups that are part of the service are highlighted.

      2. To clear the highlighting, right-click the background and select Clear Highlighting.
    5. To see the optical port or interface associated with the service endpoint, right-click the endpoint and select Navigate >Optical Port or Navigate >Interface.

      The optical port or interface associated with the endpoint is highlighted in the Network tree.

    6. To see the physical equipment in a group, double-click the optical group icon:

      The physical equipment and connections within the group are shown in a zoomed-in view.

    7. To change the size of the service view:
      1. Right-click the background and select Zoom In to increase the view size
      2. Right-click the background and select Zoom Out to decrease the view size
      3. Right-click the background and select Reset Zoom to return the view size to its original size

      Alternatively, you can use your mouse scroll wheel.

    8. To show port labels:
      1. Select an optical group icon. Right-click and choose Show Port Labels.

      2. Right-click and clear Show Port Labels to hide port labels.
    9. To see details on a link, hover over the link.

    10. Right-click a network element and select Network Element to see the regular NE menu options.
    11. To move elements in this view, drag elements to the desired location.
    12. To move all of the ports and switches in the service, choose Select All and drag the service within the window.
    13. You can save the current layout as the default, or revert to the default, or revert to the layout that PSM automatically generates.
      1. To save the current layout as the default layout for this service, right-click the background and select Save Layout as Default.

        Note: You must have administrator privileges to execute this command.

        Once the current layout is saved as the default, subsequent users who visualize this service will be able to see the current layout.

      2. To reset the current layout to the default, right-click the background and select Reset Layout to Default.
      3. To reset the current layout to the layout that PSM automatically generates, right-click the background and select Reset Layout.
    14. To save the service screen view as an image:
      1. Select Save Service Image.

        The Save Service Image dialog appears.

      2. Navigate to the desired folder and enter the filename.

        The default file format is png. To save the file in jpg format, enter .jpg at the end of the filename.

      3. Click Save.

    You have successfully completed this procedure.

    Activating an Optical Service in a BTI7000 Network

    Activating an Optical Service Between BTI7000 Optical Port Endpoints

    Use this procedure to configure and activate an optical service between BTI7000 optical ports across a BTI7000 network. The BTI7000 optical network is called the BTI7000 Series Dynamic Optical Layer (DOL).

    1. Select Tools >Service Activation >Optical >Ports. Alternatively, click the Service Activation button on the toolbar, and select Optical >Ports.

      Optical ports service activation is used when the specified endpoints are ports on optical equipment, such as a service between BTI7000 DOL endpoints.

      The Activate Optical Service panel opens.

    2. In the Service tab, enter the required information as described in the following table.

      Table 1: Fields in the Activate Optical Service Dialog

      Field

      Description

      Required field?

      Alien/C2

      When selected, the service is not provisioned to add or drop on the multiplexer/demultiplexer, but on the Alien/C2 port of the ROADM module.

      Note: This option is not available for selection in a split ROADM node. In a split ROADM node, the Alien/C2 interface is used to connect the ROADM modules together and cannot be configured for Add/Drop wavelengths.

      Optional

      Path

      Choose from a drop-down list of possible paths from Site A to Site Z. Each path has the following format:

      <Site A> to <Site Z> [via <Site N1>[; <Site N2>[;...]]]

      where <Site Nx> represents a decision point for a ROADM with more than two degrees. Each decision point specifies the incoming and outgoing degrees for the path through that NE. See Examples of path selection in a BTI7000 Series optical network .

      Note: By default, the maximum number of spans that a path can have is 10. If your path requires more than 10 spans, contact Juniper Networks Support to increase this limit.

      Yes

      Channel

      Choose from a drop-down list of existing channels.

      Yes

      Second Path

      When selected, the Path and Channel for the protected path can be specified. This selection is greyed out if no alternative path exists.

      Optional

    3. Click Activate.

      The PSM server sends the activation request to the network element. You can monitor the status of the request through the View >Server >Tasks window. The new service appears in the Network tree a short while after the task completes successfully. As part of service activation, PSM creates all the necessary optical cross-connects along the path between the specified endpoints.

      You must wait for the activation tasks to complete before performing any other operation on the NEs affected by this activation.

    You have successfully completed this procedure.

    Activating an Optical Service Between Transponder Interface Endpoints

    Use this procedure to set up a BTI7000 optical service between transponder interfaces residing on BTI7800 Series network elements, MX Series or PTX Series routers, or QFX Series switches.

    This procedure creates a new service that can be viewed in PSM as either a transport service or an optical service. The transport service component shows the transponder endpoints connected across the transport network. The optical service component shows the underlying optical network between the multiplexer/demultiplexer endpoints.

    Prerequisites:

    • The BTI7000 optical network must be set up and an optical channel (wavelength) must be available between the two endpoints across the network.
    • If an interface endpoint is on an MX Series or PTX Series router or QFX Series switch, the interface endpoint must already exist. You cannot use PSM to create an interface endpoint on a router or switch.
    • The interface endpoints must be configured properly with the same modulation, FEC, and line encoding, and use the same wavelength. To configure an interface on a BTI7800 UFM, see Editing an Interface. To configure an interface on an MX Series or PTX Series router or QFX Series switch using PSM, see Editing an Interface.

    Table 2 shows the optical service endpoint pairings that PSM supports.

    Note: PSM does not perform compatibility validation of the interface endpoints prior to service activation other than to ensure that the endpoints are allowed according to Table 2 and that the wavelengths configured at both interface endpoints are the same.

    If you configure the interface endpoints to have incompatible modulation schemes or FEC settings, PSM will set up the optical service but will not be able to set up the transport service. PSM will show the unsuccessful transport service as semi-stranded (with incompatible endpoints). This is no different than if you were to connect the misconfigured endpoints together directly instead of through an optical network.

    Note: The Site A and Site Z designations in the table above are used only to distinguish between the two interface endpoints. They are assigned arbitrarily and are interchangeable.

    Figure 1 shows devices with transponder interfaces connected across a BTI7000 optical network. The transponder interfaces attach to the optical network through a port on a BTI Series multiplexer/demultiplexer. Each port on the multiplexer/demultiplexer is associated with a different wavelength. Therefore, the attachment point on the multiplexer/demultiplexer determines the optical channel to use through the network.

    Figure 1: Optical Service Between Transponder Endpoints

    Optical Service Between Transponder Endpoints

    Note: The connection between the multiplexer/demultiplexer port and the locally-attached interface must be manually configured. This connection is not automatically learned. See step 1.

    Alternatively, you can activate an optical service where one or both router endpoints connect to the C2 port of a BTI7000 DOL ROADM module. This is not shown. In this situation, because the C2 port is not associated with a specific wavelength, PSM can only activate this type of service if it can determine the desired wavelength. PSM can determine the desired wavelength if the device interface endpoint has a configured wavelength or if the other service endpoint is connected to a multiplexer/demultiplexer. For more information on this special configuration, contact Juniper Networks Support.

    1. Before you can activate this service, you must configure the actual connection between the multiplexer/demultiplexer port and the locally-attached interface endpoint if you have not already done so.

      This is performed by configuring the Remote ID on the respective multiplexer/demultiplexer port. For information on how to do this, see Setting the Remote ID on a multiplexer/demultiplexer.

      Note: Each port on the multiplexer/demultiplexer is associated with a specific wavelength. The multiplexer/demultiplexer port on which you configure the Remote ID must be at the same wavelength as the interface endpoint to which it is connected.

      For example, this configures the Remote ID on channel 570 (195.70 THz) on the multiplexer/demultiplexer to point to a locally-attached BTI7800 UFM interface at 10.228.220.104, slot 2, subslot 1, port 1. Note that the UFM interface must also be configured for the 195.70 THz frequency.

      The following example configures the Remote ID on channel 185 (191.85 THz) on the multiplexer/demultiplexer to point to a locally-attached router interface at 192.168.7.50, slot 1, MIC 0, port 0. Note that the interface must also be configured for the 191.85 THz frequency.

      Click OK. The PSM server sends the configuration request to the network element. You can monitor the status of the request through the View >Server >Tasks window.

    2. Repeat step 1 to configure the connection between the other multiplexer/demultiplexer and the other router. You must use the same channel number.
    3. Verify that the Remote ID configuration has taken effect.

      Right-click the multiplexer/demultiplexer port/channel at each end and select Remote ID >Edit and confirm that the settings are correct in the resulting Provision Remote Port ID dialog. Do not proceed to the next step until the Remote IDs are correct at both ends.

    4. Create the service.

      Select Tools >Service Activation >Optical >Interfaces. Alternatively, click the Service Activation button on the toolbar, and select Optical >Interfaces.

      Optical interfaces service activation is used when the specified endpoints are interfaces that connect to the optical network, such as a service between transponder interface endpoints across a BTI7000 DOL network.

      The Activate Optical Service panel appears.

    5. In the Optical tab, enter the required information as described in the following table.

      Table 3: Fields in the Activate Optical Service Panel

      Field

      Description

      Required field?

      User-defined name that uniquely identifies the service.

      Yes

      Customer

      Select from the drop-down list. To add a customer to the list, select Edit>Add Customer from the main menu. For more information on adding customers, see Adding a Customer.

      Optional

      Site A

      Choose the interface endpoint from the drop-down menu. The drop-down menu lists all possible endpoints. It does not matter which end you choose as Site A.

      Yes

      Site Z

      Choose the other interface endpoint from the drop-down menu. The drop-down menu lists all possible endpoints for Site A. PSM creates this list based on the Remote ID configurations and the availability and compatibility of Site Z.

      Yes

      Path

      Choose from a drop-down list of possible paths from Site A to Site Z. Depending on the optical network topology, there might be more than one path through the network.

      Note: By default, the maximum number of spans that a path can have is 10. If your path requires more than 10 spans, contact Juniper Networks Support to increase this limit.

      Yes

    6. Click Activate.

      The PSM server sends the activation request to the device. You can monitor the status of the request through the View >Server >Tasks window. The new service appears in the Network tree a short while after the task completes successfully. As part of service activation, PSM creates all the necessary optical cross-connects along the path between the specified endpoints.

      You must wait for the activation tasks to complete before performing any other operation on the NEs affected by this activation.

    Note: This procedure creates a new service that can be viewed in PSM as either a transport service or an optical service. The transport service component shows the transponder endpoints connected across the transport network. The optical service component shows the underlying optical network between the multiplexer/demultiplexer endpoints. For information on how to view these services, see Visualizing a transport service and Visualizing an optical service respectively.

    Note: If an optical service already exists between the multiplexer/demultiplexer ports and you subsequently configure the Remote IDs on those ports, then PSM automatically creates the accompanying transport service.

    Examples Of Path Selection in a BTI7000 Optical Network

    When you activate an optical service, you need to select the first (primary) path and channel, and optionally the second (protected) path and channel between the service endpoints. All paths and channels are selected from drop-down menus in the Activate Optical Service dialog. The drop-down menus list all the valid possibilities. A second path can only be selected if an alternative path exists. Otherwise the Second Path check box is greyed out and cannot be selected.

    The path itself might contain decision points. A decision point refers to the decision that needs to be made when traversing ROADM nodes with more than 2 degrees. When more than 2 degrees exist, there can be multiple outgoing degrees for each incoming degree. The decision point qualifies the path by specifying the incoming and outgoing degrees through these nodes.

    Selecting Paths and Channels

    Figure 2 shows the selection of the first path and channel for a service between NEW-YORK and MIAMI. The topology is a ring with 2-degree ROADMs in NEW-YORK, MIAMI, and DALLAS, and a line amplifier node in CHICAGO. The first path is chosen to be the shortest path around the ring.

    Figure 2: Selecting the First Path and Channel

    Selecting the First Path and Channel

    Figure 3 shows the selection of the second path and channel. In this topology, a second path is possible via CHICAGO and DALLAS.

    Figure 3: Selecting the Second Path and Channel

    Selecting the Second Path and Channel

    Selecting a Path with No Decision Points

    Figure 4 shows the selection of a path with no decision points. The topology is a ring with 2-degree ROADMs in NEW-YORK, MIAMI, and DALLAS, and a line amplifier node in CHICAGO. The path merely specifies the start and end points.

    Figure 4: Selecting a Path with No Decision Points

    Selecting a Path with No Decision Points

    Selecting a Path with One Decision Point

    Figure 5 shows the selection of a path with one decision point. A 4-degree ROADM is at 10.1.207.9 while the other sites contain 2-degree ROADMs. The decision point is at 10.1.207.9 going from degree 1 to degree 2, representing the most direct path between 10.1.207.1 and 10.1.207.2.

    Figure 5: Selecting a Path with One Decision Point

    Activating an Optical Service in a BTI7800 Network

    Use this procedure to configure and activate an optical service on a BTI7800 network.

    Prerequisites

    • All required intra-node fiber connections are created. These are the fiber connections that connect the endpoint to the ROADM module and between ROADM modules.
    • All required inter-node fibers are physically connected. These are the line span fibers that connect ROADM nodes together.
    • All required line port optical channels are created on all nodes that the service traverses.
    1. Select Tools >Service Activation >Optical >Interfaces. Alternatively, click the Service Activation button on the toolbar, and select Optical >Interfaces.

      Optical interfaces service activation is used when the specified endpoints are interfaces that connect to the optical network, such as a service between UFM interface endpoints across a BTI7800 Series optical network.

      Optional

      Site A

      Choose from a drop-down menu of existing sites and channels. PSM provides a list of all possible endpoints. The Site A endpoint can be an interface on a UFM or, if configuring an alien wavelength, an optical channel on a ROADM client port.

      An alien wavelength is a wavelength that is added and dropped to a local external endpoint. The external endpoint can be on a UFM on a different BTI7800, or on other vendors' equipment. Since the endpoint is external and beyond the management of PSM, the endpoint you select for an alien wavelength is an optical channel on the ROADM client port.

      Yes

      Site Z

      Choose from a drop-down menu of existing sites and channels. PSM provides a list of all possible endpoints that can be reached from Site A. PSM creates this list based on the fiber connections and the existence and availability of the optical channel from Site A all along the path to Site Z.

      The Site Z endpoint can be an interface on a UFM or, if the endpoint is external (alien wavelength), an optical channel on a ROADM client port.

      Yes

      Path

      Choose from a drop-down list of possible paths from Site A to Site Z.
