    Icons and Definitions

    Topology map icons appear in the topology Map view. Service icons appear in the different service views.

    Table 1: Topology Map Icons

    Icon

    Description

    A network element.

    A router.

    Multiple connections (links) between network elements. To determine whether to display this icon, PSM counts the connections for all layers currently being displayed. For this icon to be meaningful, ensure that you only select a single layer in the topology Map view. Otherwise, PSM displays this multi-link icon when there is a single connection at more than one layer (e.g. a connection at layer 0 and a connection at layer 1).

    A link down-up indication next to a link to indicate that the link has recently gone down and come back up. The length of time that this indication is displayed is configurable (Setting topology display options).

    A link connecting network elements in a split ROADM node configuration.

    A replication cluster member. When server replication is enabled and working, this is found on the PSM server you are logged on to, and on all members of the same server replication cluster.

    A network element that has been marked. See Marking or Unmarking a Network Element.

    Table 2: Service Icons

    Icon

    Description

    General service icons

    A network element.

    A module, appears when expanding a network element in a service.

    A service endpoint.

    This is also used to indicate a Transport or Ethernet service in the Transport or Ethernet branches of the Network tree.

    A multi-layer service.

    Logical connection between an endpoint and the network element or module.

    Optical service icons

    ROADM Node: a collection of modules providing add/drop/passthrough capability.

    Line Amplifier Node: a collection of modules providing line amplification between two spans.

    Line Equalizing Node: a collection of modules providing channel equalization between two spans.

    ROADM Terminal Node: a collection of modules providing add/drop capability with channel equalization in a linear span.

    An optical service endpoint.

    This is also used to indicate an Optical service in the Optical or Transport branches of the Network tree. In the Transport branch, this indicates the transport service component of an optical service with transponder interface endpoints. See Activating an Optical Service Between Transponder Interface Endpoints.

    Fiber connection between nodes (with span length displayed in kilometers).

    A link connecting network elements in a split ROADM node configuration.

    Ethernet service icons

    A UNI endpoint.

    An NNI endpoint.

    An RPL link passing traffic in an ERPS service.

    A blocked RPL link in an ERPS service.

    A failed link in an ERPS service.
