Constraints on loopbacks of the TN53ND2 board

118

A loopback on the TN53ND2 board can apply only to service granularities received from the backplane side. For example, ODU0 granularities received from the backplane side can be looped back, but ODU1 granularities multiplexed from ODU0 granularities cannot be looped back on the TN53ND2 board.

Method for determining whether the wavelength of the TN53ND2 board is tunable

Query board manufacturer information and check the description of the module. "Tunable" indicates that the wavelength of the optical module is tunable.

Whether a TN53ND2 board can substitute for a TN12ND2 board on an OSN 8800

A TN53ND2 board can substitute for a TN12ND2 board but cannot substitute for a TN11ND2 board.

Method used to release a board loopback

On the NMS, when the Auto Disabling parameter is set to Disabled for a board loopback, the loopback will be released within the configured Auto Disabling Time. If the automatic release function is disabled, release the loopback on the NMS.

Constraints on loopbacks of the TN53NS2 board

A loopback on the TN53NS2 board can apply only to service granularities received from the backplane side. For example, ODU0 granularities received from the backplane side can be looped back, but ODU1 granularities multiplexed from ODU0 granularities cannot be looped back on the TN53NS2 board.

Constraints on loopbacks of the TN53NQ2 board

A loopback on the TN53NQ2 board can apply only to service granularities received from the backplane side. For example, ODU0 granularities received from the backplane side can be looped back, but ODU1 granularities multiplexed from ODU0 granularities cannot be looped back on the TN53NQ2 board.
