Setting an E1/T1 Input as Reference
An E1 or T1 input can be configured as a frequency reference. For details about
configuring the E1 or T1 input parameters, see Provisioning the Programmable
E1/T1 Inputs, on page 318.
Example
To provision I/O ports 1 and 2 as inputs and use either as the reference, perform the
following steps:
1. Login at the Admin or Config-user level (see Logging In, on page 275).
2. Type

Note: Command “set ref mode time” has the same meaning as
“set tod-source GPS” and the command “set ref mode
frequency” has the same meaning as “set tod-source sys”.
The
set tod-source command has been deprecated.
Note: The reference criteria MANUAL is no longer supported. Only
PRIORITY and SSM are supported for reference selection.
Manual selection of a reference input can be done by disabling all
reference input ports except the desired one.
The “set ref override” command is no longer supported.
Note: Disabling the input port will clear all alarms and events related
to this port.
