Create Topological Link

Different type of Topological Links that can be created from Topology View > Network View (Nodes) window are:

SDH/SONET: It creates TL between two STM/OC capacity ports.
Ethernet: It creates TL of type "packet trunk".
DWDM: It creates Higher Order TL between two MDU common port when there is an amplifier trunk or an MDU to MDU connection.
Amplifier: It creates trunk between amplifier to amplifier ports and between amplifier to MDU common ports. It also creates MDU (common) to MDU (common) trunk.
RADIO: It creates the radio trunk between two radio ports.
OTN: It creates TL between two OTU ports.
OTN-DWDM: It creates TL between OTU port to MDU's client port.
OSC: This feature is not supported in this product release.
Intra-Node
- DWDM Intra Node: It creates port connect between transponder/muxponder's OTU ports to MDU's add-drop port.
- Encapsulation: It creates VCG to VCG TL.
Inter-Partition: It creates TL (SDH/Ethernet/Radio/OTN/OTN-DWDM/DWDM/Amplifier) between two nodes in different partitions.

Perform the following steps to create a SDH/SONET or Ethernet topological link:

Go to Topology menu and click Topology View option. Topology View window is displayed.
Click Network View (Nodes) tab and select the desired partition from the left hand navigation pane.
Select the two desired nodes by using CTRL button (nodes get highlighted in pink upon selection).
The node you select first becomes the Source Node and the second becomes the Destination Node.
Click (Create Topological Link). Create Topological Links window is displayed.
Select TL Type as SDH/SONET or Ethernet and its Capacity as desired from the drop-down list.
Select the Source Port and the Destination Port on the source and destination nodes respectively from the drop-down list. Enter the values in remaining fields as desired. For more information, refer Create Topological Links parameters table.
Click OK. TopoLogical Link Creation Request Sent message is displayed.
Click OK.
An Ethernet TL is represented as dashed green line whereas a SDH TL as solid green line.

Create Topological Links parameters

Field	Description

TL Type	Select the TL Type as desired from the drop-down list. The options available are: SDH/SONET RADIO OTN OTN-DWDM Ethernet DWDM Amplifier
User Label	Enter the value to be used to identify the topological link. By default, the value is 'Tejas Networks'.
Source Node	Displays the IP address of the selected local or source node.
Destination Node	Displays the IP address of the selected remote or destination node.
Capacity	Displays the capacities supported on the corresponding TL Type. Select the desired capacity for the TL type selected.
TL Mode	Select the TL mode from the options listed as follows: Offline: means the information about the TL being created will be on NMS and EMS only. Online: means the information about the TL being created will be on NMS, EMS, and node. Manual: means these are logical TLs for representation purpose only and information will be present only in NMS and EMS. This mode is supported only for TL creation between TJ1400P-M switches and other Tejas nodes.
Source Port	Select the source port on the node from the drop-down list.
Destination Port	Select the destination port on the node from the drop-down list.
NOTE: Additional details are provided about the selected TL Type and TL Mode on Create Topological Links window.
