SONET
The SONET area contains the following information:
•
SONET Overhead J0 Byte—Value of the SONET overhead section trace byte. A value of 0x10 is
for interoperability with some Synchronous Digital Hierarchy (SDH) devices in Japan. This attribute
is read-only.
•
SONET Overhead C2 Byte—Value of the SONET overhead path signal identifier. This attribute is
read-only. These are possible values:
–
0xCF = PPP or HDLC
–
0x13 = ATM
•
SONET Overhead S1 S0 Bits—Value of the SONET overhead S1 & S0 bits. These bits are part of
the payload pointer byte. This attribute is read-only. These are possible values:
–
0 = OC-3c
–
2 = AU-4
