The information in this appendix, combined with your estimates of anticipated traffic on a group of channels, enables you to use traffic tables. Traffic Series - Tables For Traffic Management And Design. The tables in Frankel's publication are computer derived and preceded by a detailed explanation of their contents and range of parameters. The book also includes general descriptions of traffic characteristics, examples of the application of traffic tables to practical applications, and a selected bibliography on traffic engineering. When determining the number of service circuit channels for your system, ensure that all traffic estimates reflect the volume of traffic anticipated during the system's busy hour .
Traffic volume is measured in a numeric value.
This value indicates the average number of simultaneously existing calls. The Erlang is the basic unit of measurement for traffic used in traffic tables. Traffic tables offer a means for determining the number of service circuits or channel DS0s needed to carry a given volume of traffic in relation to a stated probability of loss. Users generate their calls independently of each other. Expected traffic density is the same for every user.
