4.11.6 Encapsulation/Mapping
The equipment supports the setting of encapsulation and mapping protocols for Ethernet packets,
including the parameters such as mapping protocol, scrambling code, and CRC or not.
lists the parameters that are used for configuring the encapsulation and mapping of
an Ethernet port.

Field
Value Range
Description
Port
VCTRUNKn
Indicates the VCTRUNK
port. The letter n indicates the
number of the VCTRUNK
port.

Scramble
Unscrambled, Scrambling
mode[X43+1], Scrambling
mode[X48+1]
Default value: Scrambling
mode[X43+1]
NOTE
The OptiX OSN 550 does not
support
Scramble mode[X48
+1]
.
The
Scramble
parameter
specifies whether to scramble
the payload area of the
encapsulation protocol and
the scramble mode.
You can set this parameter
only when the mapping
protocol is GFP, HDLC, or
LAPS.

Set Inverse Value for CRC
Yes, No
Default value: Yes
The
Set Inverse Value for
CRC
parameter specifies
whether to set an inverse
value for the CRC field of the
HDLC
or
LAPS
protocol.
You can set this parameter
only when the mapping
protocol is HDLC or LAPS.
