class TerminalDevice.LogicalChannels.Channel.Otn.State

Bases: Entity

Class Hierarchy : TerminalDevice LogicalChannels Channel Otn State

This class represents state data.

Operational state data for OTN protocol PMs, statistics,

etc.

tti_msg_transmit

Trail trace identifier (TTI) message transmitted

type: str

config: False

tti_msg_expected

Trail trace identifier (TTI) message expected

type: str

config: False

tti_msg_auto

Trail trace identifier (TTI) transmit message automatically created. If True, then setting a custom transmit message would be invalid

type: bool

config: False

tti_msg_recv

Trail trace identifier (TTI) message received

type: str

config: False

rdi_msg

Remote defect indication (RDI) message received

type: str

config: False

errored_seconds

The number of seconds that at least one errored blocks occurs, at least one code violation occurs, loss of sync is detected or loss of signal is detected

type: int

range: 0..18446744073709551615

config: False

severely_errored_seconds

The number of seconds that loss of frame is detected OR the number of errored blocks, code violations, loss of sync or loss of signal is detected exceeds a predefined threshold
