inhibit auto. OS messages ABN This message occurs when TL1 autonomous alarm
reporting is inhibited by the TL1 INH-MSG
command. This message is cleared by enabling
autonomous message reporting with the TL1
ALW-MSG command.
inhibit switch ABN When associated with an OC-3/OC-12 line, this
message means that the identified line is not
selected as the active receiving line, and a
protection switch to make this the active receiving
line will not be done. No further protection
switching of specified line will be done until the
protection switch is reset.
Note:
OC-3/OC-12 line
switching is unidirectional. Because of this, the
specified OC-3/OC-12 line might still be active (if
the far end is selecting the specified line to receive
traffic), and the far end might still be free to switch
the line it is selecting to receive traffic. (See the
switch-line: command.)
When associated with a FUNCTION UNITS slot or
timing reference, this message means that the
identified equipment or reference is not active, and
protection switches to the identified equipment or
reference will not be done until the protection
switch is reset. (See the switch-fn: and
switch-sync: commands.)
lockout of protection ABN When associated with an OC-3/OC-12 line, this
message means that the identified line is not
selected as the active receiving line, and a
protection switch to make this the active receiving
line will not be done.
Note:
OC-3/OC-12 line
switching is unidirectional. Because of this, the
specified OC-3/OC-12 line might still be active (if
the far end is selecting the specified line to receive
traffic), and the far end might still be free to switch
the line it is selecting to receive traffic. The lockout
will remain in effect until the protection switch is
reset or until a protection switch inhibit request is
entered. (See the switch-line: command.)
When associated with a LOW SPEED (
LS
)
protection slot, this message means that no service
slot in the whole low speed group
will be allowed to
switch to protection. The lockout will remain in
effect until the protection switch is reset. (See the
switch-ls: command.)
