Enumeration
Controls how the J1 trail trace insertion
should work, i.e. how the j1TxTrailTrace
parameter shall be inserted in the line
signal.
Important: there is only one j1TxTrailTrace
per interface, while each interface may
me mapped to one or more VC4s/VC3s.
For that reason there are two modes:
- vcGroupLevel:
The string j1TxTrailTrace is used identically
for each VC (4/3) in the VC-group related to
the interface.
Each VC transmits exactly the same string.
The string may be 15 bytes (1 byte CRC
as added in HW).
- individualVcLevel:
In this mode the system adds a unique suffix
for each VC (3/4). The trace for each VC
will therefore be unique. The suffix will be 6
bytes and contain the following information:
<VCG Size><Seq number><VC position>
ss nn pp
=> 'ssnnpp'
where
<VCG Size>: ss
The size of the VC group, i.e. the
number of contained VCs.
Value coded in hex
2 bytes
<Seq number>: nn
Sequence number of the VC within the
VC group coded in hex.
2 bytes
<VC position>: pp
The position of the VC (3/4) within
the STM16 frame, coded in hex.
2 bytes.
The user part of the string is 9 bytes.
6 bytes is added as suffix + 1 CRC byte.
