Expected J1
447
Defines the Expected J1 Trace to be received on the
incoming SDH signal.
The J1 Trace is part of the Higher-Order Path Overhead
(also known as the HP Trace), where the J1 byte is
configured as a repeating 64-byte, 16-byte or 1-byte pattern
that can be configured as the system's default ASCII pattern,
a customized user-defined ASCII pattern, or a 1-byte
hexadecimal pattern.
The following Expected J1 Trace options are available:
•
Default (64 byte) - Selects the default 64-byte ASCII
message as the expected trace pattern. The message
consists of 62 ASCII characters appended with CR
and LF characters at the end of the message.
•
User Defined (64 byte) - Selects a 64-byte user-
defined ASCII message as the expected trace pattern.
The message is entered and saved using a touch
screen keyboard. The user-defined message can be
up to 62 ASCII characters, appended with CR and LF
characters at the end of the message.
•
Default (16 byte): Selects the default 16-byte ASCII
message as the expected trace pattern. The message
consists of 15 ASCII characters, appended with a
CRC-7 at the end of the message.
•
User Defined (16 byte): Selects a 16-byte user-
defined ASCII message as the expected trace pattern.
The message is entered and saved using a touch
screen keyboard. The user-defined message can be
up to 15 ASCII characters, appended with a CRC-7 at
the end of the message.
•
All 01's - Selects an All Ones (0x01) hexadecimal
pattern as the expected trace pattern. The 0x01 byte
value repeats indefinitely and does not contain CRC-7.
•
All 00's - Selects an All Zeros (0x00) hexadecimal
pattern as the expected trace pattern. The 0x00 byte
value repeats indefinitely and does not contain CRC-7.
•
User Defined (1 byte): Selects a user-defined
Hexadecimal byte value as the expected trace pattern.
The byte value is entered and saved using a touch
screen keypad (from 0x00 to 0xFF). The byte value
