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 Capacity Index

Go Cost Capacity Index = (Number of Subscriber Lines*Switching Capacity)/Cost per Subscriber

Cost per Subscriber

Go Cost per Subscriber = (Number of Subscriber Lines*Switching Capacity)/Cost Capacity Index

Downtime

Go Downtime = (Uptime-Availability*Uptime)/Availability

Average Number of Call

Go Average Number of Calls = (Average Occupancy*Time Period)/Average Holding Time

Average Holding Time

Go Average Holding Time = (Average Occupancy*Time Period)/Average Number of Calls

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

Uptime

Go Uptime = (Availability*Downtime)/(1-Availability)

Traffic Handling Capability

Go Traffic Handling Capacity = (2*Switching Capacity)/Number of Subscriber Lines

Switching Capacity

Go Switching Capacity = (Number of Subscriber Lines*Traffic Handling Capacity)/2

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

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

Unavailability of System Formula

Unavailability = 1-Availability
U = 1-A

What is Unavailability of the system?

When the line is too busy and the system is unavailable for the user is known as the unavailability of system

How to Calculate Unavailability of System?

Unavailability of System calculator uses Unavailability = 1-Availability to calculate the Unavailability, Unavailability of System refers to the state or condition where the system or specific components within the system are unavailable. It represents the period of time during which the system or its components are not accessible, not functioning correctly, or experiencing an outage. Unavailability is denoted by U symbol.

How to calculate Unavailability of System using this online calculator? To use this online calculator for Unavailability of System, enter Availability (A) and hit the calculate button. Here is how the Unavailability of System calculation can be explained with given input values -> 0.3 = 1-0.7.

FAQ

What is Unavailability of System?

Unavailability of System refers to the state or condition where the system or specific components within the system are unavailable.
