Release 5.1
Release A2
Functional Notes
When operating on a circuit that is providing timing, setting the clock source to line can avoid errors, such
as clock slip seconds (CSS).
Usage Examples
The following example configures the unit to recover clocking from the primary circuit:
(config)#interface e1 1/1
(config-e1 1/1)#clock source line
60000CRG0-35E
Configures the unit to provide clocking using the internal oscillator.
Configures the unit to recover clocking from the E1 circuit.
Configures the unit to provide clocking from the chassis selection.
Configures the unit to recover clocking from the circuit connected to the
G.703 interface.
Command was introduced.
Command was expanded to include the system parameter.
