Overview of the Working Mode(NG WDM NEs)

This topic describes the board working mode and port working mode. A specific service signal flow of a board is available when the board working mode and port working mode are set to specific values.

Board Working Mode

The Web LCT supports a variety of board working modes.

The 12LQMS board supports NS1 mode and LQM mode.

**Table 1** 12LQMS Board Mode
Board mode	Description
NS1 mode	The 12LQMS board functions as a line board that performs mutual conversion between the ODUk electrical signals and the optical signals at a WDM system-compliant standard wavelength.
LQM mode	The 12LQMS board functions as a tributary board that performs mutual conversion between the client-side signals and the optical signals at a WDM system-compliant standard wavelength.

The 11TOM and 52TOM boards support the Cascading and Non-Cascading modes.

**Table 2** 11TOM/52TOM Board Mode
Board mode	Description
Cascading	A maximum of eight multi-rate (< 2.5 Gbit/s) client-side services can be input to the TN11TOM board through the SFP module on the client side. The services are then multiplexed into different timeslots of one or two ODU0 services or one ODU1 service. Each group of ClientLP ports, for example, 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP1)-8 ports, can access a maximum of eight client-side services.
Non-Cascading	A maximum of eight multi-rate (< 2.5 Gbit/s) client-side services can be input to the TN11TOM board through the SFP module on the client side. The services are then multiplexed into different timeslots of one to eight ODU0 services or one to four ODU1 services. Each group of ClientLP ports, for example, 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP1)-4 ports, can access a maximum of four client-side services.

NOTE:

A specific service signal flow of the 52TOM board is available only when both the board working mode and port working mode are set to specific values.

Port Working Mode

The 52TOM board should be set to the cascading or non-cascading mode. In addition, application scenarios such as the ODU0 or ODU1 mapping mode and tributary or tributary-line mode of the ports on the board should be set. As shown in Table 3, the 52TOM board supports 14 working modes.

**Table 3** Mapping between the working modes and signal flows of the 52TOM board
Board Working Mode	Port Working Mode	Signal Flow	Flow Chart
Cascading	ODU0 mode	Any->ODU0[->ODU1]	Service Signal Flow
	ODU0 tributary-line mode	Any->ODU0->ODU1->OTU1	Service Signal Flow
	ODU1 mode	Any->ODU1	Service Signal Flow
	ODU1 tributary-line mode	Any->ODU1->OTU1	Service Signal Flow
	None (not for ports)	-	-
Non-Cascading	ODU0 mode	Any->ODU0[->ODU1]	Service Signal Flow
	ODU0 tributary-line mode	Any->ODU0->ODU1->OTU1	Service Signal Flow
	ODU1 mode	OTU1/Any->ODU1	Service Signal Flow
	ODU1_ODU0 mode	OTU1->ODU1->ODU0	Service Signal Flow
	ODU1_ANY_ODU0 re-encapsulation mode	OTU1->ODU1->Any->ODU0	Service Signal Flow
	ODU1_ANY_ODU0_ODU1 re-encapsulation mode	OTU1->ODU1->Any->ODU0->ODU1	Service Signal Flow
	ODU1_ANY_ODU0_ODU1 re-encapsulation tributary-line mode	OTU1->ODU1->Any->ODU0->ODU1->OTU1	Service Signal Flow
	ODU1 tributary-line mode	OTU1/Any->ODU1->OTU1	Service Signal Flow
	None (not for ports)	-	-

NOTE:

[->**]: indicates that "**" is optional. For example, in non-cascading ODU0 mode, there are two service signal flows: Any->ODU0 and Any->ODU0->ODU1.
None mode: indicates that the resources at this port are not used and are released to other ports.

The TN11TOM board supports five working modes listed below. You can set the port working modes on the NMS.

**Table 4** Mappings between the working modes and the service mapping paths
Board Working Mode	Port Working Mode	Mapping Path
Cascading mode	ODU1 tributary mode	OTU1/Any->ODU1
Cascading mode	ODU1 tributary-line mode	OTU1/Any->ODU1->OTU1
Non-Cascading	ODU1 tributary mode	OTU1/Any->ODU1
	ODU1 tributary-line mode	Any->ODU1->OTU1
	ODU1 tributary-line mode (electrical regeneration board)	OTU1->ODU1->OTU1

The 54TOA and 54THA boards should be set to the ODU0 or ODU1 mapping mode and aggregation or non-aggregation mode of the ports on the board. As shown in Table 5, the 54TOA board supports 5 working modes. The 54THA board supports the same working modes as the 54TOA board.

As shown in Table 6, the 53TDX, 53TQX and 55TQX boards supports 2 working modes.
