Optical Bypass

An optical bypass switch that works in conjunction with a probe’s Bypass Power

connector to maintain the network link even when a probe has an interruption in

power.

OSI

Open Systems Interconnect. The 7 level communications structure promoted by

ISO.

Packet

A bit stream consisting of predefined fields that contain data, addresses, and

control information. In the IEEE 802.3 environment, this structure is often

referred to as the MAC frame. Packet is used in the Ethernet environment and is

used in this guide because it is the more commonly understood term. Different

protocols have different packet and frame specifications.

PAIS

Path Alarm Indication Signal

Pass-Through

The method of connecting Agilent Probes so that additional hub ports or an

additional hub is not required to monitor a connection. Some probe options are

designed to support the pass-through mode and allow the probe to be connected

between a server and a switch or between two switches without requiring an extra

hub.

Path

A logical connection between the point at which a standard frame format for the

signal at the given rate is assembled, and the point at which the standard frame

format for the signal is disassembled.
