API
The Access Point Identifier (API) is the label that is inserted in the path overhead. This
is not valid if the TI Mode is set to Non Specific Byte.
API display mode
As long as the characters forming the API are alphanumeric characters, it is possible to
toggle between HEX and Alphanumeric mode. The accepted API displays
non-alphanumeric characters as question marks in the Alphanumeric mode. If
Alphanumeric box cannot be checked, please delete the content in the API field first.
TIM detection
TIM is Trace Identifier Mismatch comparison between the expected and accepted TTI.
If this is enabled and TP is monitored, when the TTIs do not match, a Path Trace
Identifier Mismatch alarm is raised.
Important! If the Trace Identifier Mismatch (TIM) detection is enabled, traffic will
be lost when a mistake in the trace string is made. Upon mismatch, an Alarm
Indication Signal (AIS) is inserted in the downstream signal and Remote Defect
Indicator (RDI) is inserted in the upstream signal
