This section identifies voice bandwidth requirements for WAN links. The most important issue is the number of simultaneous calls that are permitted across the WAN link.

120 ms. 94 ms. none Seattle to San Jose 26 ms. 102 ms. 76 ms. none Determining Voice Bandwidth Requirements Voice bandwidth requirements depend on a number of parameters, including the sampling rate, codec, link type, header compression techniques, and the number of simultaneous voice calls. This section identifies voice bandwidth requirements for WAN links. The most important issue is the number of simultaneous calls that are permitted across the WAN link. The organization can limit the number of calls via call admission control; however, with a centralized call processing model, attempts that are made at calling capacity will simply busy out.

We normally recommend at least one week with three weeks being ideal. Busy hour utilization is important because it mimics telecom capacity planning time periods and helps to understand peak hourly utilization requirements during busy periods. Average utilization is less useful because it generally includes weekend or nighttime utilization that misrepresents business periods. Pay close attention to detail when collecting and analyzing the peak link utilization value since several factors can misrepresent the baseline results.
