The rear panel of the Timing Client contains the following components as shown in Figure 2:

A pair of DC terminals each with positive, negative, and ground terminals is used to connect a DC power source to the Timing Client. The LAN port is an RJ45 connector with synch and activity LEDs, which can be used to connect the Timing Client to a PC for managing the Timing Client through an Internet browser. The GPS antenna port is used to connect the Timing Client with an appropriate GPS L1 antenna that receives a minimum GPS signal from a Timing Server. Two BITS ports are used to receive input from BITS clock sources. Timing output ports are used to deliver 1/5/10 MHz output signal and PPx output signal. The PPx output signal can be PPS, PPM, PPS2, or Pulse-Position Hopping (PPH). The rear LEDs mirror the front LEDs and provides the power status and alarm status of the Timing Client.
