る。2. Description of the Related Art In the case where a plurality of small-sized exchanges are integrated to form one network, conventionally, a method of introducing an exchange serving as a central station and controlling each small-scale exchange by this central station is used. Has been. In such a case, two signal systems, that is, an individual line signal system and a common line signal control system are known as the signal systems connecting the respective exchanges. However, in the individual line signaling system, it is basically difficult to provide the service across the exchanges, that is, between the stations, because the information for connecting the exchanges cannot be exchanged basically. Therefore, if you want to combine multiple exchanges so that they can operate as if they were a single exchange, so that you can provide services that span each station, you can use the other signal instead of the individual line signaling method described above. A common line signaling system, which is a system, is used. That is, by connecting a plurality of exchanges by this common line signaling system and exchanging control information via this common line, even if a service extends over a plurality of exchanges, it is possible to connect to one exchange. Various service functions are realized.

等に行うことができないという問題があった。However, even if a plurality of exchanges are connected by using the common line signaling system, there are restrictions on the numbering plan and service transparency (transparency of service functions) as described below. Occurs. That is, for example, if the extension number of each exchange to be integrated is set to be arbitrary,
The central office switch cannot identify the switch accommodating the extension number without expanding all digits of the extension number. Therefore, there is a problem that the processing at the central station becomes complicated and the capacity of the memory for storing the extension number of each exchange increases. Further, for maintenance, when one terminal is replaced by another exchange from one exchange, there is a troublesome problem that the data must be changed in the exchange of the central office and the three exchanges of the respective exchanges. . Furthermore, in the common line signaling system, signal propagation delay generally occurs,
There has been a problem that services between stations and services between extensions cannot be performed at exactly the same level.
