Virtual end office in a switched telephone network |
摘要 |
Methods and apparatus implementing a technique for a virtual end office. The virtual end office includes one or more pre-switch adjuncts forming a single logical construct. Each pre-switch adjunct is connected to a local exchange switch in a telephone network and provides special services to subscribers. The pre-switch adjuncts have a common exchange prefix code and so a subscriber can access special services from anywhere in the network by using the same exchange prefix code, so long as the switch the subscriber is using is connected to a pre-switch adjunct.
