Example
In this example call traffic is not expected to exceed 8 simultaneous calls.
Eight trunks for calls between any two DBS systems should be adequate.
However, under the T1 configuration being considered, a call can be relayed
by an intermediary DBS. In this case, a call will pass through one DBS to get
to another. Therefore a maximum of 16 network trunks between any two
systems should be enough. All remaining T1 trunks may be split off to handle
CO calls. Figure 2-5 illustrates the determined network trunk configuration.
