Description
The S1 Byte
Synchronization Quality
Information parameter
indicates the synchronization
quality information in the S1
byte that is output by the
current traced synchronous
source. The S1 byte defined
by the ITUT is used to
transmit the quality
information about the clock
sources. It indicates the
quality information of 16
types of synchronous sources
with bits 5-8 of the S1 byte in
the section overhead. With
this quality information and
certain switching protocols,
the automatic protection
switching of the
synchronization clock can be
realized in the synchronous
network.
You can click 7.126 S1 Byte
Synchronization Quality
Information to display the
detailed information.
Displays the clock source
that is traced by the clock of
the current NE. This
parameter is used for query
only.
The relevant information can
be displayed only when the
S1 byte is used. That is, the
clock protection function is
enabled. Similarly, the
relevant information can be
displayed only when you
click Query. Otherwise, only
NA is displayed.
