Regenerator Section Overhead

Normally, the default values of the overhead bytes to be received or transmitted are adopted to meet the relevant requirements. You should configure the J0 byte in the regenerator section overheads when the J0_MM alarm is reported at the local or remote NE. In this user interface, you can query and set the mode and contents of the regenerator section overhead byte J0.

Navigation Path

In the NE Explorer, select the board and choose Configuration > Overhead Management > Regenerator Section Overhead from the Function Tree.

Parameters

Field	Value	Description
Object	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 operation object.
J0 to be Sent ([Mode]Content)	For example: [16 Bytes]HuaWei SBS	Sets the regenerator section trace byte J0 to be sent of the port. The default value is usually used. [Mode] indicates whether the overhead byte is of the single-byte mode, 16-byte mode or 64-byte mode. You can fill in a maximum of 15 bytes. Two byte modes are supported: single-byte mode and 16-byte mode (the first byte is generated automatically). If the remote NE reports the J0_MM alarm, set this parameter according to the J0 byte to be received at the remote NE.
J0 to be Received ([Mode]Content)	For example: [16 Bytes]HuaWei SBS	Queries the regenerator section trace byte J0 to be received of the port. Three byte modes are supported: single-byte mode, 16-byte mode (the first byte is generated automatically), and disable mode. When this parameter is set to Disable Mode, the board does not detect the received J0 byte. It is recommended that this parameter takes the default value.
J0 Received ([Mode]Content)	For example: HuaWei SBS	Queries the regenerator section trace byte J0 received of the port.
Input in Text Format	For example: HuaWei SBS	Enters the overhead bytes. When setting overhead bytes in text mode, use only ASCII characters.
Byte Mode	Single byte, 16-byte (first byte created automatically), 64-Byte Mode (With Synchronization Bit 0x0D/0x0A), 64-byte (without synchronization bit), Disable Mode	Selects the overhead byte mode.
Input Mode	Text Format, Hexadecimal	Selects the mode of entering the overhead bytes.
