Configuring the LSX Board

The LSX board is applicable to two scenarios: transparent transmission of one channel of 10G bit/s optical signals and regeneration of one channel of OTU2 or OTU2v optical signals.

Prerequisite

You must have logged in to the NE where the board resides.

Tools, Meters, and Materials

Web LCT or T2000

Navigation Path

1. In the NE Explorer, select the board and then choose Configuration > WDM Interface from the Function Tree.

2. Select a proper navigation path according to the parameters. The details are as follows: l In the case of a parameter at channel level, select By Board/Port(Channel), choose

Channel from the drop-down list, and click the Basic Attributes or Advanced Attributes tab. Then, you can query or set the corresponding parameter.

l In the case of a parameter at board level, select By Board/Port(Channel) and choose Board from the drop-down list. Then, you can query or set the corresponding parameter.

NOTE

You can also select By Function and then choose the required parameter from the drop-down list.

Parameter Settings

Field Value Description

Service Type 10GE LAN, OTU-2,

OTU-2v, STM-64 Default: OTU-2

Select a proper value according to the received services.

Port Mapping Bit Transparent Mapping (11.1 G), MAC Transparent Mapping (10.7 G) Default: Bit Transparent Mapping (11.1 G)

This parameter is valid when Service Type is set to 10GE LAN.

l When a board is used to transparently transmit synchronous Ethernet services, this parameter must be set to Bit Transparent Mapping (11.1 G).

l Select Bit Transparent Mapping (11.1 G) when there are OTU2v signals on the WDM side.

l Select MAC Transparent Mapping (10.7 G) when there are OTU2 signals on the WDM side.

NOTE

l Port mapping of the two boards that are interconnected with each other must be consistent.

Field Value Description FEC Working State Enabled, Disabled Default: Enabled l Enabled is recommended.

l FEC Working State of the two interconnected OTU boards must be consistent.

FEC Mode FEC, AFEC

Default: FEC

This parameter is available only when you set FEC Working State to Enabled.

l The default value is recommended. To improve the error correction capability, set this parameter to AFEC.

l FEC Mode of the two boards that are interconnected on the WDM side must be consistent. Otherwise, services are interrupted. Channel Use

Status

Used, Unused Default: Used

l Set this parameter to Unused when a channel that is not used.

l Set this parameter to Used when a channel that is used.

Automatic Laser Shutdown

Enabled, Disabled Default: Enabled for client-side optical interfaces, and Disabled for WDM- side optical

interfaces.

l The default value is recommended.

l This parameter must be set to Disabledin the case of WDM-side optical ports. That is, other values are invalid.

In practical application, set this parameter according to the scenario where the board is used. For example, when the LSX board is used for regenerating OTU2 or OTU2v signals, set

Automatic Laser Shutdown to Disabled for RX/ TX and IN/OUT optical interfaces.

Hold-Off Time of Automatic Laser Shutdown 0s to 2s, with a step of 100 ms. Default: 0s

Field Value Description Laser Status Open, Close

Default:

l WDM side: Open l Client side: Close

l Usually, this parameter is set to Open for every WDM-side optical interface.

l In the case of client-side optical interfaces, retain the default value because Automatic Laser Shutdown is usually set to Enabled.

In practical application, set this parameter according to the scenario where the board is used. For example, when the LSX board is used for regenerating OTU2 or OTU2v signals, set Laser Status to On for RX/TX and IN/OUT optical interfaces.

CAUTION

If the communication between NEs is achieved through only the ESC provided by the LSX board, the following situations occur when neither a standby channel is available nor protection is configured:

l When the LSX board is used for regenerating OTU2 or OTU2v signals, the NE becomes unreachable after the lasers at the RX/TX and IN/OUT optical interfaces on the LSX board are disabled.

l When the LSX board is used for transparently transmitting the 10 Gbit/s optical signals, the NE becomes unreachable after the lasers at the IN and OUT optical interfaces on the LSX board are disabled.

Non- Intrusive Monitoring Status Enabled, Disabled Default: Disabled

This parameter is valid when the board is used to receive SDH services. The default value is recommended. Optical Interface Loopback Non-Loopback, Inloop, Outloop Default: Non- Loopback

Set this parameter to Non-Loopback when a network works normally. It can be set to Inloop or Outloop to help locate a faulty point in a test or a process of removing a fault on a network. However, it must be set to Non-Loopback right after the test is complete or the fault is removed.

When Automatic Disabling of NE Function is set to the default value Enabled, the loopback setting is automatically cancelled after Auto Disabling Time (default: 5 minutes) elapses.

Max. Packet Length

1518-9600 Default: 9600

This parameter is valid when Service Type is set to 10GE LAN and Port Mapping is set to MAC Transparent Mapping (10.7 G). The default value is recommended. SD Trigger Condition SM_BIP8_SD, PM_BIP8_SD, B1_SD Default: None

This parameter is valid only when the SD Trigger Flag is set to Enable.

all the alarms can be set as the SD switching conditions.

Field Value Description LPT Enabled Enabled, Disabled

Default: Disabled

This parameter is valid when Service Type is set to 10GE LAN and Port Mapping is set to MAC Transparent Mapping (10.7 G).

l The LPT function can work only with intra- board 1+1 protection and cannot work with any other protection.

l Set this parameter to Enabled when you want to enable the LPT function; otherwise, keep the default value for this parameter.

PRBS Test Status

Enabled, Disabled Default: /

l Retain the default value when a network works normally.

l Set this parameter to Enabled for the auxiliary board if you need to perform a RPBS test during deployment commissioning. Set this parameter to Disabled after the test is complete.

Band Type/ Wavelength No./ Wavelength (nm)/ Frequency (THz)

The parameter format is as follows: band type/wavelength No./ optical interface wavelength/ frequency, for example, CWDM/ 11/1471.00/208.170. Default: -

This parameter is for query only.

Band Type C, CWDM

Default: /

This parameter is for query only.
