Configuration Process

Procedure

1. Set the Working Mode of the 52TOM board. In the NE Explorer, select a 52TOM board, and choose Configuration > Working Mode from the Function Tree. Set Board Working mode to Non-Cascading and then set Port Working Mode to ODU1 tributary-line mode (OTU1/Any->ODU1->OTU1). For details, see Configuring the Working Mode of the 52TOM Board.
2. In Path View, set the type of client-side ports 9 (RX7/TX7) and 10 (RX8/TX8) to Line Side Color Optical Port. For details, see Modifying Ports.
   NOTE:

   When the 52TOM board is used as a tributary & line board, a corresponding WDM-side optical module must be inserted in the WDM-side optical interface, and the Type of this optical interface must be changed to Line Side Color Optical Port.

3. In the NE Explorer, select the desired board , and choose Configuration > WDM Interface from the Function Tree. Set Service mode of the 52TOM board to OTN mode. For details, see Configuring the Service Mode.
   NOTE:

   When the 52TOM board accesses OTU1 services on the client side, you first need to set the Service Mode of the 52TOM board to OTN mode.

4. In the NE Explorer, select the desired board , and choose Configuration > WDM Interface from the Function Tree. Configure the Service Type at the WDM interface of the 52TOM as OTU1. For details, see Configuring the Service Type.
5. Configure the cross-connections from the RX/TX ports to the ClientLP ports on the 52TOM board for the OTU1 services of the board.
   1. Configure the cross-connections from the RX/TX ports to the ClientLP ports for the OTU1 services that are input to the 52TOM board.

      Parameters	Value
      Level	OTU1
      Service Type	-
      Direction	Bidirectional
      Source Slot	Shelf2(Subrack2)-15-52TOM
      Source Optical Port	3(RX1/TX1)
      Source Optical Channel (eg.1,3-6)	1
      Sink Slot	Shelf2(Subrack2)-15-52TOM
      Sink Optical Port	201(ClinetLP1/ClinetLP1)
      Sink Optical Channel (eg.1,3-6)	1

      NOTE:

      The Service Type must be the same as the Service Type at the WDM interface of the 52TOM board.

   2. Repeat 5.a to configure cross-connections for the other OTU1 services.
6. Configure two separate cross-connections from the internal logical port to ports 9 (RX7/TX7) and 10 (RX8/TX8) for the 52TOM board to achieve dual feeding.
   1. Configure two separate cross-connections from the internal logical port to ports 9 (RX7/TX7) and 10 (RX8/TX8) for the 52TOM board to achieve dual feeding.

      Parameters	Value
      Level	OTU1
      Service Type	-
      Direction	Bidirectional
      Source Slot	Shelf2(Subrack2)-15-52TOM
      Source Optical Port	51(ODU1LP1/ODU1LP1)
      Source Optical Channel (eg.1,3-6)	1
      Sink Slot	Shelf2(Subrack2)-15-52TOM
      Sink Optical Port	9(RX7/TX7)
      Sink Optical Channel (eg.1,3-6)	1

      Parameters	Value
      Level	OTU1
      Service Type	-
      Direction	Unidirectional
      Source Slot	Shelf2(Subrack2)-15-52TOM
      Source Optical Port	51(ODU1LP1/ODU1LP1)
      Source Optical Channel (eg.1,3-6)	1
      Sink Slot	Shelf2(Subrack2)-15-52TOM
      Sink Optical Port	10(RX8/TX8)
      Sink Optical Channel (eg.1,3-6)	1

      NOTE:

      The working channel port and the protection channel port are the two ports for dual feeding. The service in the working channel must be set as bidirectional, and the service in the protection channel must be set as unidirectional. In this example, port 9 (RX7/TX7) in the working channel port, and port 10 (RX8/TX8) is the protection channel port.

   2. Repeat 6.a to configure two separate cross-connections from the internal logical port to ports 7 (RX5/TX5) and 8 (RX6/TX6) for the 52TOM board to achieve dual feeding.
7. Configure the selective receiving feature for the WDM side of the 52TOM board.
   1. In the NE Explorer, select the NE and choose Configuration > Port Protection.
   2. In the Port Protection user port, click New. In the Confirm dialog box displayed, click OK. The Create Protection Group dialog box displayed. Select Intra-Board 1+1 Protection from the Protection Type. Enter the other parameters of the protection group. For details of parameters, see the Feature Description.

      Parameters	Value
      Protection Type	Intra-Board 1+1 Protection
      NE with Working Channel	NE8850
      Board with Working Channel	Shelf2(Subrack2)-15-52TOM
      Working Channel	9(RX7/TX7)
      NE with Protection Channel	NE8850
      Board with Protection Channel	Shelf2(Subrack2)-15-52TOM
      Protection Channel	10(RX8/TX8)

   3. Click OK. In the window that is displayed, click Close. The created protection group is displayed in the window.
   4. Repeat 7.b and 7.c to configure the selective receiving feature of the ports 7 (RX5/TX5) and 8 (RX6/TX6) for the 52TOM board.
