• If the line keyword is specified for all interfaces, the clock on the interface with the lowest number
is used. If the interface goes down, the clock on the interface with the second lowest number is used.
• If the line primary keywords are specified for one interface and the line or internal keyword is
specified for all other interfaces, the clock on that one interface is used.
• If the line keyword is specified for one interface and the internal keyword for all other interfaces, the
clock on that one interface is used.
• The clock source of only one interface can be set to line primary.
The TDM clock sources on the local and peer devices must match. For example, if the clock source is set
to line for a subsystem on the local device, the clock source must be set to internal on the peer device, and
vice versa.
Examples
# Configure the clock on the peer device as the clock source for interface E1 1/0.
<Sysname> system-view
[Sysname] controller e1 1/0
[Sysname-E1 1/0] tdm-clock line
# Configure the clock on the peer device as the clock source for interface T1 1/0.
<Sysname> system-view
[Sysname] controller T1 1/0
[Sysname-T1 1/0] tdm-clock line
