Number of MedPros needed

D Capacities and Performance

The following table gives the approximate carried load (CLm), in Erlangs, for m MedPro boards installed. Carried loads are shown for a = 22 and 31 audio streams per MedPro board, corresponding to having the G.723 or G.729A (a=22) or the G.711 (a=31) codecs administered.

Assumptions

This table assumes:

In columns 2 and 3, the carried loads are calculated assuming an infinite source for Grade of Service (GOS) of P001. The carried loads are calculated as an average of Erlang B and Erlang C to account for retrials

In columns 3 and 4, the carried loads are calculated assuming full availability (no blocking). Note that the carried load for the full availability case is just the number of audio streams times the number of MedPro boards.
