All systems enjoy the advantages of PRI tandem trunks, which are made possible
in this larger network by the greater line capacity of the hub DEFINITY ECS or
DEFINITY ProLogix Solutions, System E. In this private network, the systems
may be spread across thousands of miles and realize considerable toll savings on
intersystem calls and long-distance ARS calls. Although not shown, each system
has its own voice mail/auto attendant system.
