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
(Calculation completed in 00.004 seconds)

Cost of Common Hardware
Go Cost of Common Hardware = Cost of Switching System-(Number of Switching Element*Cost per Switching Element)-Cost of Common Control System
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
Time Required for Functions other than Switching
Go Time Required Other than Switching = Call Setup Time-Number of Switching Stage*Average Switching Time per Stage
Call Setup Time
Go Call Setup Time = Time Required Other than Switching+Number of Switching Stage*Average Switching Time per Stage
Cost per Subscriber
Go Cost per Subscriber = (Number of Subscriber Lines*Switching Capacity)/Cost Capacity Index
Cost Capacity Index
Go Cost Capacity Index = (Number of Subscriber Lines*Switching Capacity)/Cost per Subscriber
Downtime
Go Downtime = (Uptime-Availability*Uptime)/Availability
Average Holding Time
Go Average Holding Time = (Average Occupancy*Time Period)/Average Number of Calls
Average Number of Call
Go Average Number of Calls = (Average Occupancy*Time Period)/Average Holding Time
Average Occupancy
Go Average Occupancy = (Average Number of Calls*Average Holding Time)/Time Period
Trunk Occupancy
Go Trunk Occupancy = Occupancy*(1-Grade of Service)/Average Occupancy
Switching Capacity
Go Switching Capacity = (Number of Subscriber Lines*Traffic Handling Capacity)/2
Uptime
Go Uptime = (Availability*Downtime)/(1-Availability)
Traffic Handling Capability
Go Traffic Handling Capacity = (2*Switching Capacity)/Number of Subscriber Lines
Number of Lost Call
Go Number of Lost Calls = Total Number of Offered Calls*Grade of Service
Total Number of Offered Calls
Go Total Number of Offered Calls = Number of Lost Calls/Grade of Service
Grade of Service
Go Grade of Service = Number of Lost Calls/Total Number of Offered Calls
Availability
Go Availability = Uptime/(Uptime+Downtime)
Average Poisson Call Arrival Rate
Go Average Poisson Call Arrival Rate = Poisson Arrival/Time Period
Poisson Arrival
Go Poisson Arrival = Average Poisson Call Arrival Rate *Time Period
Quantization Error
Go Quantization Error = Sinusoidal Input/(2*Voltage)
Unavailability of System
Go Unavailability = 1-Availability

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.
