Number of Lost Call Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Lost Calls = Total Number of Offered Calls*Grade of Service
NL = Tc*GoS
This formula uses 3 Variables
Variables Used
Number of Lost Calls - Number of lost calls refers to the count or quantity of calls that are not successfully connected or completed due to various reasons such as network congestion, other limitations within the system.
Total Number of Offered Calls - Total number of offered calls refers to the total count of incoming calls or connection attempts that are presented to the switching system within a specific time period.
Grade of Service - Grade of Service is often associated with call blocking. It indicates the probability that a user will experience a blocked call, where the system cannot allocate the necessary resources.
STEP 1: Convert Input(s) to Base Unit
Total Number of Offered Calls: 25.87 --> No Conversion Required
Grade of Service: 0.27 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
NL = Tc*GoS --> 25.87*0.27
Evaluating ... ...
NL = 6.9849
STEP 3: Convert Result to Output's Unit
6.9849 --> No Conversion Required
FINAL ANSWER
6.9849 <-- Number of Lost Calls
(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 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

Number of Lost Call Formula

Number of Lost Calls = Total Number of Offered Calls*Grade of Service
NL = Tc*GoS

What is the Grade of Service?

The Grade Of Service formula is defined as the probability of a call in a circuit group being blocked or delayed for more than a specified interval, expressed as a vulgar fraction or decimal fraction.

How to Calculate Number of Lost Call?

Number of Lost Call calculator uses Number of Lost Calls = Total Number of Offered Calls*Grade of Service to calculate the Number of Lost Calls, Number of lost calls refers to the count or quantity of calls that are not successfully connected or completed due to various reasons such as network congestion, insufficient resources, or other limitations within the system.It means that the switching system was unable to allocate the necessary resources or establish a connection between the calling and receiving parties. Number of Lost Calls is denoted by NL symbol.

How to calculate Number of Lost Call using this online calculator? To use this online calculator for Number of Lost Call, enter Total Number of Offered Calls (Tc) & Grade of Service (GoS) and hit the calculate button. Here is how the Number of Lost Call calculation can be explained with given input values -> 6.9849 = 25.87*0.27.
