The answer is that one can still implement all the above with a Centrex system at any or all locations. Because Centrex is essentially a PBX that is physically resident at the local central office, it too can have TIE, FX, or RCF trunks. The long distance carrier supplying the VPN will be more than happy to terminate VPN trunks on a Centrex system. In summary, the important points are as follows: • Calls are carried over the PSTN. • A custom dialing plan is used. • Pricing is dependent on the locale.
To answer that question, we must consider the impact on our business if the data we are sending is • Simply lost. Is there a backup mechanism for sending or recovering the data? • Found by another business (not a competitor). • Found by a competitor. • Actively pursued by a competitor as shown in Figure 4−2. Figure 4−2: Competitors may actively pursue your data. In the last case, we must ask how much effort is the competitor willing to invest to get our data? The answer to these questions will help us decided how much security is enough.
As progress occurs, the use of Local Number Portability (LNP) and Intelligent Networks (IN) enables the competitors to break in and offer new services to the consumer. Note that there have been some changes in this numbering plan. When it originally was formulated, the telephone numbers were divided into three sets of sequences. The area codes were set to designate high−volume usage and enabled some number recognition tied to a state boundary. With the convergence in full swing, the numbering plan became a bottleneck.
