Uptime Solution

STEP 0: Pre-Calculation Summary

Formula Used

Uptime = (Availability*Downtime)/(1-Availability)
u = (A*d)/(1-A)
This formula uses 3 Variables

Variables Used

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.
Availability - Availability refers to the ability of the system to remain operational and accessible to users over a given period of time.
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

Availability: 0.7 --> No Conversion Required
Downtime: 6.85 Second --> 6.85 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

u = (A*d)/(1-A) --> (0.7*6.85)/(1-0.7)

Evaluating ... ...

u = 15.9833333333333

STEP 3: Convert Result to Output's Unit

15.9833333333333 Second --> No Conversion Required

FINAL ANSWER

15.9833333333333 ≈ 15.98333 Second <-- Uptime

Cost of Switching System

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

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

Number of Lost Call

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

Grade of Service

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

Uptime Formula

Uptime = (Availability*Downtime)/(1-Availability)
u = (A*d)/(1-A)

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.

How to Calculate Uptime?

Uptime calculator uses Uptime = (Availability*Downtime)/(1-Availability) to calculate the Uptime, 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. It represents the opposite of downtime and measures the reliability and continuous availability of the system.Measuring and maximizing uptime is a critical objective for telecommunication service providers. It ensures reliable communication services. Uptime is denoted by u symbol.

How to calculate Uptime using this online calculator? To use this online calculator for Uptime, enter Availability (A) & Downtime (d) and hit the calculate button. Here is how the Uptime calculation can be explained with given input values -> 15.98333 = (0.7*6.85)/(1-0.7).

FAQ

What is Uptime?

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. It represents the opposite of downtime and measures the reliability and continuous availability of the system.Measuring and maximizing uptime is a critical objective for telecommunication service providers. It ensures reliable communication services and is represented as u = (A*d)/(1-A) or Uptime = (Availability*Downtime)/(1-Availability). Availability refers to the ability of the system to remain operational and accessible to users over a given period of time & Downtime refers to the period during which the system or specific services provided by the system are unavailable or non-operational.
