ENQ2 Board Service Configuration

On the U2000 Web LCT, the logical ports of the board are provided.

Port Description

The TN54ENQ2 board can work in standard or compatible mode.

NOTE:

For information about the standard and compatible modes of the board, see the Product Description.

Figure 1 shows the board model of the TN54ENQ2 board in compatible mode. Table 1 lists the descriptions of the ports on the board.
Figure 2 shows the board model of the TN54ENQ2 board in standard mode. Table 2 Lists the descriptions of the ports on the board.

NOTE:

A TN54ENQ2 board can support only one mode simultaneously.

Figure 1 Diagram of ports on the TN54ENQ2 (compatible mode)

NOTE:

There are cross-connections between ports 141 (OCHLP9/OCHLP9)-1 to 144 (OCHLP12/OCHLP12)-1 on the NPO2 board and ports 71 (ODU2LP1/ODU2LP1)-1 to 74 (ODU2LP4/ODU2LP4)-1 on the ENQ2 board. You do not need to configure these cross-connections on the U2000 Web LCT.

	Cross-connect module		ODU1 mapping path
	Multiplexing module		ODU2 mapping path
	Service processing module		Automatic cross-connection, which does not need to be configured on the NMS. For example, if ODU0 signals are required, users only need to configure cross-connections from other boards to the ODU0LP port on the board using the NMS. The board's internal structure enables transmission of the multiplexed signal to the ODU2LP port. Users do not need to configure a cross-connection for transmitting the multiplexed signal.
	ODU0 mapping path		Cross-connection that must be configured on the NMS to receive ODUk signals from other boards

**Table 1** Meaning of ports on the TN54ENQ2 (compatible mode)
Port Name	Meaning
ODU0LP1-ODU0LP16	Internal logical ports. The optical paths are numbered 1 and 2.
ODU1LP1-ODU1LP4	Internal logical ports. The optical paths are numbered 1, 2, 3 and 4.
ODU2LP1-ODU2LP4	Internal logical ports. The optical paths are numbered 1.

NOTE:

Service cross-connections of the TN54ENQ2 board are configured on the TN55NPO2 or TN55NPO2E board (either in standard mode) using the NMS.

If an ODUk channel has been used, cross-connections cannot be configured on any other channels that correspond to the ODUk channel, regardless of the rate level. For example, if channel 1(IN/OUT)-OCH:1-ODU2:1-ODU1:1 has been used, cross-connections cannot be configured on channel 1(IN/OUT)-OCH:1-ODU2:1 or 1(IN/OUT)-OCH:1-ODU2:1-ODU1:1-ODU0:1.

	Cross-connect module		ODU1 mapping path
	Multiplexing module		ODU2 mapping path
	Service processing module		Cross-connection that must be configured on the NMS to receive ODUk signals from other boards
	ODU0 mapping path

**Table 2** Meaning of ports on the TN54ENQ2 (standard mode)
Port Name	Meaning
1(IN/OUT)-OCH:(9-12)-ODU2:(9-12)-ODU1:(1-4)-ODU0:(1-2)	Indicates the mapping path for the ODU0 signals that are received through the backplane.
1(IN/OUT)-OCH:(9-12)-ODU2:(9-12)-ODU1:(1-4)	Indicates the mapping path for the ODU1 signals that are received through the backplane.
1(IN/OUT)-OCH:(9-12)-ODU2:(9-12)	Indicates the mapping path for the ODU2/ODU2e signals that are received through the backplane.
1(IN/OUT)	Indicates the WDM-side port.

Cross-Connection Configuration of Services

When the TN54ENQ2 board works in standard mode, service cross-connections are configured on the TN55NPO2 or TN55NPO2E board using the NMS. The ODUk services processed by the TN54ENQ2 board are mapped onto OCH9-OCH12 optical channels on the TN55NPO2 or TN55NPO2E board in standard mode. For details, see NPO2 Board Service Configuration and NPO2E Board Service Configuration.

When the TN54ENQ2 board in compatible mode is used to transmit services, electrical cross-connections must be created on the U2000 Web LCT. For information on how to create ODU1 cross-connections, see Figure 4; for information on how to create ODU2/ODU2e cross-connections, see Figure 5.

NOTE:

Cross-connections can be configured between the boards working in standard mode and the boards working in compatible mode.
