External Clock Cables

External Clock Cables

On the device, the external clock cables with RJ45 connectors are used to input and output the external clock or time signals.

The external clock cables can be connected to the CLK, and TOD interfaces on an device.

Structure

Figure 6-9 shows the structure of the RJ45 connector used on the external clock cable.

Pin Assignment

The external clock cables must be made on the equipment installation site. When the CLK interfaces are used as external clock interfaces, the pin assignment of the RJ45 connector is as listed in Table 6-12; when the TOD interfaces are used as external time interfaces, the pin assignment of the RJ45 connector is as listed in Table 6-13.
