High traffic for a 0.2 Erlang capacity
Table 8: Number of handsets for a 0.2 Erlang capacity on page 46 shows the 6-channel and
12-channel basestation combinations required to support a maximum number of handsets on
a DMC card.
The calculations are based on each handset generating 0.2 Erlangs of traffic.
