flag j0

Use flag j0 to set the J0 overhead byte for SONET/SDH frames.
Use undo flag j0 to restore the default J0 overhead byte.
Syntax
flag j0 { sdh j0-string | sonet j0-value }
undo flag j0 { sdh | sonet }

Parameters
sdh j0-string: Specifies the regenerator section trace byte for SDH. The j0-string argument is a string of 1
to 15 characters.
sonet j0-value: Specifies the regenerator section trace byte for SONET. The j0-value argument is in the
range of 0x00 to 0xFF and defaults to 0x01.
Usage guidelines
J0 is a section overhead byte used for detecting the continuity of the connection between two interfaces
at the section layer. It is mainly used for interoperability of devices in different countries/regions or
devices of different vendors.
The J0 value range differs for SDH and SONET.
Description
Current physical state of the E-CPOS interface.
Description of the interface.
Physical layer information of the E-CPOS interface: the framing
format is set to SDH, AU-3 path is adopted (displayed when the
interface is channelized into E3/T3 lines), master clock mode
(internal clock signal) is used, and loopback is disabled.
Signal degrade (SD) threshold and signal fail (SF) threshold of
the E-CPOS interface.
Sent overhead bytes.
Received overhead bytes.

Types and numbers of errors that occurred:
•
BIP—Number of bit-interleaved parity (BIP) errors.
•
SEF—Severely error framing errors.
