  • Page 22 Introduction Introduction This chapter introduces the Agilent J3919A and J3972A OC-3 ATMProbes, shown in Figure 1-1 on page 3, including its installation and configuration options. The OC-3 ATMProbe supports the OC-3c, STS3C and STM-1 standards. You can use your ATMProbe with the NetMetrix/UX software, supported by HP-UX and Solaris.

  • Page 23: Figure 1-1: The Probe

    Introduction The OC-3 ATMProbe also has a 6-pin mini-DIN connector (Bypass Power) that allows ATMProbe to be connected to an external optical bypass. The optical bypass maintains the network link even if the OC-3 ATMProbe has an interruption in power; it functions only when using fiber SC connectors. Figure 1-1: The Probe The OC-3 ATMProbe has 32 MB of memory (optionally 64 or 128 MB), and uses FLASH EPROM.
