Total Number of Offered Calls Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Number of Offered Calls = Number of Lost Calls/Grade of Service
Tc = NL/GoS
This formula uses 3 Variables
Variables Used
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.
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.
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
Number of Lost Calls: 6.985 --> No Conversion Required
Grade of Service: 0.27 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tc = NL/GoS --> 6.985/0.27
Evaluating ... ...
Tc = 25.8703703703704
STEP 3: Convert Result to Output's Unit
25.8703703703704 --> No Conversion Required
FINAL ANSWER
25.8703703703704 25.87037 <-- Total Number of Offered 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 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

Total Number of Offered Calls Formula

Total Number of Offered Calls = Number of Lost Calls/Grade of Service
Tc = NL/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 Total Number of Offered Calls?

Total Number of Offered Calls calculator uses Total Number of Offered Calls = Number of Lost Calls/Grade of Service to calculate the 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. It represents the total demand or traffic load on the system, including both completed calls and those that may be blocked or abandoned. Total Number of Offered Calls is denoted by Tc symbol.
