11.7.2 Setting Clock Mode or Time Mode of a BITS Clock

Context
The BITS clock refers to the clock signal sent from the BITS interface to a network element.
The signal that a BITS clock receives depends on the signal that the BITS interface sends and
receives.
Do as follows on the S9300 as required.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
clock bits-type { bps-2m | hz-2m | bps-1544m } { bits0 | bits1 }
The clock mode is set for the BITS0 or BITS1 clock.
Or run:
clock bits-type { dcls-time | 1pps-tod } { in | out } { bits0 | bits1 }
The time mode is set for the BITS0 or BITS1 clock.
By default, the BITS clocks adopt the bps-2m mode, that is, the clock signal is transmitted at a
rate of 2 Mbit/s.

11.7.3 Setting the ID of a Clock Source

Context
If the clock signals sent from a clock source are looped back to the sender directly or through
the network, it indicates that a timing loop occurs. Timing loops should be avoided in network
design. In extended SSM mode, the higher four bits of the S1 bytes are used to transmit the clock
source ID, which reduces timing loops on the network.
Do as follows on the S9300.

Data
WTR time of a clock source
NOTE
The interconnected devices must use the same transmission mode of the BITS clock.
