J0 Byte
The J0 byte is part of the Section OH and is known as the Section trace or J0 trace.
J0 Trace
A 64-byte pattern that can be created for repeated transmission. The pattern is a string
of ASCII characters. The J0 trace can be configured to send the unit's default pattern or
a customized pattern.
J1 byte
Higher-Order VC-N path trace byte. This user-programmable byte repetitively transmits
a 15-byte, E.64 format string plus 1 byte CRC-7. A 64 byte free format string is also
permitted for this Access Point Identifier. This allows the receiving terminal in a path to
verify its continued connection to the intended transmitting terminal.
J2 byte
Used to repetitively transmit a Lower-Order Access Path Identifier so that a path
receiving terminal can verify its continued connection to the intended transmitter. A 16-
byte frame is defined for the transmission of Path Access Point Identifiers. This 16-byte
frame is identical to the 16-byte frame of the J1 and J0 bytes.
J1 Trace
The 64-byte fixed length string transmitted in the J1 Byte. See also J1 Byte.
K

In Linear APS mode, indicates the number of the channel. Code 0 = Null Channel, Code
