Command Reference Guide
timing-source
Use the timing-source command to configure the timing source used for reference timing. Use the no
form of this command to return to the default setting. Variations of this command include the following:
timing-source e1 <interface id> secondary
timing-source e1 <interface id>
timing-source internal
timing-source internal secondary
timing-source t1 <interface id>
timing-source t1 <interface id> secondary
Syntax Description
e1 <interface id>
internal
t1 <interface id>
secondary
Default Values
By default, the primary clock source is set to internal.
Command History
Release 11.1
Release A5.01
Functional Notes
If both the primary and secondary clock sources fail, the unit automatically switches to internal timing.
Usage Examples
The following example configures the unit to use an internal timing source:
(config)#timing-source internal
The following examples set the t1 0/1 interface as the primary timing source and the t1 0/2 interface as the
secondary timing source:
(config)#timing-source t1 0/1
(config)#timing-source t1 0/2 secondary
60000CRG0-35E

Provides timing using the internal 1.544 MHz clock generator.
Recovers clocking from the specified T1 or DSX-1 interface.
Optional. Signifies that the clock source specified in the command is to be
the secondary clock source.
Command was introduced.
Command was expanded to include the E1 interface.
