Availability Solution

STEP 0: Pre-Calculation Summary

Formula Used

Availability = Uptime/(Uptime+Downtime)
A = u/(u+d)
This formula uses 3 Variables

Variables Used

Availability - Availability refers to the ability of the system to remain operational and accessible to users over a given period of time.
Uptime - (Measured in Second) - Uptime refers to the period of time during which the system or its components are operational and available to provide services without any interruptions or outages.
Downtime - (Measured in Second) - Downtime refers to the period during which the system or specific services provided by the system are unavailable or non-operational.

STEP 1: Convert Input(s) to Base Unit

Uptime: 15.98 Second --> 15.98 Second No Conversion Required
Downtime: 6.85 Second --> 6.85 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = u/(u+d) --> 15.98/(15.98+6.85)

Evaluating ... ...

A = 0.699956197985107

STEP 3: Convert Result to Output's Unit

0.699956197985107 --> No Conversion Required

FINAL ANSWER

0.699956197985107 ≈ 0.699956 <-- Availability

Cost of Switching System

LaTeX Go Cost of Switching System = Number of Switching Element*Cost per Switching Element+Cost of Common Hardware+Cost of Common Control System

Total Number of Offered Calls

LaTeX Go Total Number of Offered Calls = Number of Lost Calls/Grade of Service

Number of Lost Call

LaTeX Go Number of Lost Calls = Total Number of Offered Calls*Grade of Service

Grade of Service

LaTeX Go Grade of Service = Number of Lost Calls/Total Number of Offered Calls

Availability Formula

LaTeX Go

Availability = Uptime/(Uptime+Downtime)
A = u/(u+d)

What is High Availability?

In telephone switching networks, availability or full accessibility is possible if all of the lines are equally accessible to all incoming calls. It can also be defined as a characteristic of a system which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.

How to Calculate Availability?

Availability calculator uses Availability = Uptime/(Uptime+Downtime) to calculate the Availability, Availability refers to the ability of the system to remain operational and accessible to users over a given period of time. It is a measure of reliability and uptime, indicating the percentage of time that the system is available and able to provide its intended services. Availability is denoted by A symbol.

How to calculate Availability using this online calculator? To use this online calculator for Availability, enter Uptime (u) & Downtime (d) and hit the calculate button. Here is how the Availability calculation can be explained with given input values -> 0.699956 = 15.98/(15.98+6.85).

FAQ

What is Availability?

Availability refers to the ability of the system to remain operational and accessible to users over a given period of time. It is a measure of reliability and uptime, indicating the percentage of time that the system is available and able to provide its intended services and is represented as A = u/(u+d) or Availability = Uptime/(Uptime+Downtime). Uptime refers to the period of time during which the system or its components are operational and available to provide services without any interruptions or outages & Downtime refers to the period during which the system or specific services provided by the system are unavailable or non-operational.

How to calculate Availability?

Availability refers to the ability of the system to remain operational and accessible to users over a given period of time. It is a measure of reliability and uptime, indicating the percentage of time that the system is available and able to provide its intended services is calculated using Availability = Uptime/(Uptime+Downtime). To calculate Availability, you need Uptime (u) & Downtime (d). With our tool, you need to enter the respective value for Uptime & Downtime and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
