Erlang B and IP Bandwidth Tables
Erlang B and IP Bandwidth TablesThe first table (pp. 424 to 439) specifies the number of channels required for a given blocking probability and traffic demand. Select the column corresponding to the blocking probability in question. Within that column, find the Erlang value that provides the closest match to the required Erlang value. The leftmost column of the same row provides the required number of channels.The second table (pp. 440 to 456) specifies the amount of IP bandwidth, in bits per second, required for a given number of channels for various CODEC bit rates for both IPv4 and IPv6, assuming a 20-ms sample size and silence suppression, packet loss concealment, or other redundancy mechanisms are not implemented. Having determined the number of channels required for a give…
