Leased switches pose another problem. Obviously, only one has access at a time. The Network Management Team has an agreement with the vendors to share access. Other savings are likely to come to light. It's conceivable if this system were used DoD-wide that severely underused switches would be identified.
Centralized management has other benefits.
Something as seemingly insignificant as the bulk purchase of telephone handsets would reduce the cost per unit to just a few dollars. Multiplied across DoD, the savings become significant. Based on the concept developed by NCTS Pensacola, every switch in the Navy could be managed from one location. That's the theory. See Figure 3 .
