3Com MSR 30, MSR 50 code (CEI/PRI interface view), controller e1

203
When the CE1/PRI interface is working as DCE, choose the internal clock (master)
for it. When it is working as DTE, choose the line clock for it.
Example # Use the internal clock as the clock source on CE1/PRI interface E1 2/0.
<Sysname> system-view
[Sysname] controller e1 2/0
[Sysname-E1 2/0] clock master

View CE1/PRI interface view
Parameter ami: Adopts alternate mark inversion (AMI) line code format.
hdb3: Adopts high density bipolar 3 (HDB3) line code format.
Description Use the code command to set the line code format for the CE1/PRI interface.
Use the undo code command to restore the default, that is, HDB3.
Keep the line code format of the interface in consistency with that used by the
remote device.
Example # Set the line code format of interface E1 2/0 to AMI.
