4.5.1 Transmitted Trace Identifiers
Selecting Tx Trace Identifier allows
the transmitted Trace Identifiers (TI)
to be set up.
Three trace identifiers are transmitted,
the Regenerator Section TI (J0), the
High Path TI (J1), and the Low Path
TI (J2).
The RS-TI can be set to 1 byte or 16
bytes in length. The HP-TI and LP-TI
can be set to 16 bytes or 64 bytes in
length. If the RS-TI is set to 1 byte, its
contents are entered in the form of
two hexadecimal digits. During this
entry, the function keys are
temporarily assigned the alphabetical values ‘A’ to ‘F’. The two hexadecimal digits can
be entered by using the keyboard for the decimal numbers and the function keys for
the alpha characters.
4.5.2 Trace Identifiers
To set up the trace identifiers, select
the TIM Setup view. Three trace
identifiers can be optionally
monitored, by checking the box
alongside each trace identifier field
(RS-TIM, HP-TIM or LP-TIM). If the
received values differ from the values
preset within this page, and the
respective box is checked, a defect
alarm is raised and noted within the
Results pages.
The RS-TIM can be set to 1 byte or
16 bytes in length. The HP-TIM and
LP-TIM can be set to 16 bytes or 64
bytes in length. If the RS-TIM is set to
1 byte, its contents are entered in the form of two hexadecimal digits. During this
entry, the function keys are temporarily assigned the alphabetical values ‘A’ to ‘F’. The
two hexadecimal digits can be entered by using the keyboard for the decimal numbers
and the function keys for the alpha characters.
