SDH Interface

In this user interface, you can query and set parameters for SDH interfaces of an NE.

Navigation Path

In the NE Explorer, click a board and choose Configuration > SDH Interface from the Function Tree.

NOTICE:
  • Setting the loopback status of the optical (electrical) interface or VC4 to inloop or outloop may interrupt the running service and ECC. Think twice before using the function.
  • The laser must be set to the enabled status during normal operation. If it is set to disabled, the optical interface cannot receive/send service signals.

Parameters

Field

Value

Description

Board

NE name-slot number-board name

Displays the board.

Board Working Mode

AUTO Mode, SONET Mode

Sets the board working mode.

  • AUTO Mode: Selects the board working mode automatically based on the current service of the board. The mode switches to SONET mode for the AU3 service, and to SDH mode for non-AU3 service.
  • SONET Mode: Sets SONET mode for boards that need to be configured with the AU3 service or its protection service.
NOTICE:

Services may be interrupted during board working mode switching. Exercise caution when setting this parameter.

Port
  • Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name)
  • Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)

Displays the name of the port.

MS-SPR

Enable

Disable

Sets multiple multiplex section protection ring.

VC3 Path
  • Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name)
  • Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)

Displays the VC3 Path.

Optical Interface Name

For example: SDH-1

Sets the name of the Optical interface.

Overhead Transfer Mode

GCC Mode, DCC Mode

Sets the overhead transfer mode.

MSP Sharing

Enabled, Disabled

Set the MSP sharing. If this function is enabled, you can configure multiple MSPs at one port.

Laser Switch

On, Off

Default: On

Sets the laser switch status of the line board. Turn-on is usually selected.

Object: optical interface

Laser Transmission Distance (m)

For example: 80000

Displays the valid distance of the signal that the laser transmits.

Optical (Electrical) Interface Loopback

Non-Loopback, Inloop, Outloop

Default: Non-loopback

Sets the SDH interface loopback status of the equipment. Non-loopback is usually selected.

Object: optical interface or electrical interface

Non-loopback: Normal status, you do not need to set loopback during normal equipment operation.

Outloop: The input signal passes the input port and reaches the line board at the local NE and then is directly looped back to the service output end.

Inloop: The input signal returns from the line board of the destination NE along the original trail.

This function is usually used to locate faults for various ports. Optical (electrical) interface loopback is a diagnosis function which may affect services of related ports. Think twice before using it.

VC4 Path
  • Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name)-channel number
  • Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)-channel number

Displays the VC4 Path.

VC4 Loopback

Non-Loopback, Inloop, Outloop

Default: Non-loopback

Sets the VC4 loopback status of the line board. Non-loopback is usually selected.

Object: VC4 channel.

Non-loopback: Normal status, you do not need to set loopback during normal equipment operation.

Outloop: The input signal passes the input port and reaches the line board at the local NE and then is directly looped back to the service output end.

Inloop: The input signal returns from the line board of the destination NE along the original trail.

This function is usually used to locate faults for various VC4 channels. VC4 loopback is a diagnosis function which may affect services of related VC4 channels. Think twice before using it.

VC3 Loopback

Non-Loopback, Inloop, Outloop

Default: Non-loopback

Sets the VC3 loopback status of the line board. Non-loopback is usually selected.

Object: VC3 channel.

Non-loopback: Normal status, you do not need to set loopback during normal equipment operation.

Outloop: The input signal passes the input port and reaches the line board at the local NE and then is directly looped back to the service output end.

Inloop: The input signal returns from the line board of the destination NE along the original trail.

This function is usually used to locate faults for various VC3 channels. VC3 loopback is a diagnosis function which may affect services of related VC3 channels. Think twice before using it.
