Advanced Attributes

In this interface, you can query and set the advanced attributes of the SDH interface.

Navigation Path

In the NE Explorer, click the NE and choose Configuration > Interface Management > SDH Interface from the Function Free. Then, click the Advanced Attributes tab.
In the NE Explorer, click the board and select Configuration > Interface Management > SDH Interface from the Function Tree. Then, click the Advanced Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for Advanced Attributes of the SDH interface
Field	Value	Description
Port	Slot-Board Name-Port (Port No.)	Display the port name.
Laser Transmission Distance	For example: 1000	Display the transmission distance of the laser.
Scrambling Capability	Enabled, Disabled Default: Enabled	When the ATM cell payload scrambling is enabled, several "0"s and "1"s in the data are suppressed.
CRC Check Length	16, 32	Displays the CRC check length.
Clock Mode	Master Mode, Slave Mode	Displays the clock mode. Master Mode indicates that the internal clock signals are adopted. Slave Mode indicates that the line clock signals are adopted.
CES Encapsulation Clock Mode	NULL, Line Clock Mode, System Clock Mode	Sets the encapsulation mode of the clock signal at the UNI port on the master side of the CES service. NULL: indicates that clock signals are not encapsulated into service packets. Line Clock Mode: indicates that the clock frequency signals extracted at the line port are encapsulated into the RTP packet header as time stamp information, and then are sent to the downstream. System Clock Mode: indicates that the system clock frequency information is encapsulated into the RTP header as time stamp information, and then are sent to the downstream.
CES Encapsulation Clock Poke	Disabled, Enabled	Configure an E1 port to generate a time stamp on the master NE. NOTE: When CES ACR is in line clock timestamp mode, the master NE must enable an E1 to generate a time stamp. At the same time, only one E1 port can be enabled on one NE. When one E1 port is enabled to generate a time stamp, if you enable another E1 port, an error message indicating a parameter error will be displayed.
Loopback Mode	Non-Loopback, Inloop, Outloop	Set the loopback status of the port.
