Figure 45: Connect an ACX7348 Router to a Network for Out-of-Band Management
Connect to 1-PPS and 10-MHz Timing Devices
Each ACX7348 router has SubMiniature B (SMB) connector ports that support 1 pulse per second (1-
PPS) and 10-megahertz (10-MHz) timing devices.
NOTE: Ensure that you use a cable of 3 m or less in length for the 10-MHz and 1-PPS
connectors.
To connect the SMB-to-BNC coaxial cable to the external clocking input port:
1. Connect one end of the SMB-to-BNC coaxial cable to either the 1-PPS connector or the 10-MHz
connector on the router.
2. Connect the other end of the SMB-to-BNC coaxial cable to the 1-PPS or 10-MHz measurement
equipment.
NOTE: Ensure that the 10-MHz or 1-PPS source network equipment contains a low-voltage
complementary metal oxide semiconductor (CMOS) or is compatible with low-voltage (3.3 V)
transistor-transistor logic (TTL).
