E1 Set Flag - HP 6600 Command Reference Manual

Default command level
2: System level
Parameters
e1-number: Number of an E1 channel on the CPOS interface, in the range of 1 to 63.
master: Sets the clock mode of the E1 channel to master.
slave: Sets the clock mode of the E1 channel to slave.
Usage guidelines
E1 channels on the same CPOS physical interface can use different clock modes, depending on
connected devices. For example, when connected to a SONET/SDH device, an E1 channel should use
the slave clock mode. When directly connected to another device through an optical fiber, the E1
channel must use different modes at the two ends.
Different E1 channels of the same CPOS physical interface are independent of one another in terms of
clock mode.
Examples
# Set the clock mode of E1 channel 1 to master.
<Sysname> system-view
[Sysname] controller cpos 2/0/0
[Sysname-Cpos2/0/0] e1 1 set clock master
