    timing source


    timing source selector { internal | line lineType | uidType interfaceSpecifier }

    Release Information

    Command introduced before JunosE Release 7.1.0.


    Configures the router’s timing sources. Only one of these timing sources can be an external source received through an interface on an I/O module other than the SRP I/O module; the other two must be either internal sources or external sources received through the SRP I/O modules. There is no no version.

    • internal—Specifies the internal SC oscillator
    • line—Specifies external timing input on the SRP module
    • lineType—One of the following timing sources:
      • e1:a—E1 clock, port A on SRP module
      • e1:b—E1 clock, port B on SRP module
      • t1:a—T1 clock, port A on SRP module
      • t1:b—T1 clock, port B on SRP module
    • uidType—One of the following interfaces:
      • ds1—Specifies a DS1 interface
      • ds3—Specifies a DS3 interface
      • e1—Specifies an E1 interface
      • e3—Specifies an E3 interface
      • sonet—Specifies a SONET interface

        Note: On the E120 and E320 routers, you can specify sonet for only two of the available three timing sources (primary, secondary, or tertiary).
