Connecting the MX104 Router to External Clocking and Timing Devices
The MX104 router supports external clock synchronization for Synchronous Ethernet, T1
or E1 line timing sources, and external inputs.

Connecting 1-PPS and 10-MHz Timing Devices to the MX104 Router
The MX104 router has four SMB connectors that support 1-PPS and 10-MHz timing
devices.
NOTE: Ensure a cable of 3 m or less in length is used for the 10-MHz and
1-PPS connectors.
To connect the SMB coaxial cable to the external clocking input port:
1. Connect one end of the SMB coaxial cable to either the 1-PPS SMB connector or the
10-MHz SMB connector on the router.
2. Connect the other end of the SMB coaxial cable to the 10-MHz or 1-PPS source network
equipment.
NOTE: Ensure that the 10-MHz or 1-PPS source network equipment
contains a complementary metal oxide semiconductor (LVCMOS) of a
low voltage of 50 ohms or is compatible with low-voltage
transistor-transistor logic (LVTTL) (3.3v).
