Configuring SONET
The following sections describe how to set a variety of SONET commands:
• Optionally Disabling SONET Payload Scrambling
• Changing the SONET Framing Type
• Changing the CRC Function on the POS Interface
• Defining SONET Frame Overhead Bytes
Table 14-4 describes the SONET features and commands that are available on the
POS module:
Table 14-4 SONET Commands
Command Description Default Value
pos scramble Scrambling algorithm used
for the SONET payload
enabled disabled or enabled
pos framing
POS interface framing
type
sonet sdh or sonet
pos crc
Number of bits used for
CRC checking
16 16 or 32 check digits
per frame. Also the
crc can be optionally
set for big-endian
byte order.
pos flag c2 The c2 byte in the SONET
frame is the path signal
identifier.
0xCF Hexadecimal value
for the protocol
encapsulation. For
example, PPP is
0xCF.
pos flag c2-exp Path signal identifier
expected from the far end
SONET equipment
0xCF Hexadecimal value
for the protocol
encapsulation.
pos flag j0 Defines hexadecimal
single byte message
0x1 Hexadecimal value.
