Title: Intra office network
Inventor: HIGUCHI HIROKO
IPC: H04M3/00
Filed: 1994-12-15
Abstract: PURPOSE: To enable an extension terminal at another enterprise spot at low cost without laying a leased line by connecting the exchange at a large-scale enterprise spot which is connected by a multiplex leased line and the exchange at a small-scale enterprise spot. CONSTITUTION: When the number of a telephone set 1400 at the large-scale enterprise is dialed by operating a telephone set 1400 at the small-scale enterprise spot, the exchange 1300 at the small-scale enterprise spot calls the exchange at an intermediate-scale enterprise spot coupled with ISDN through ISDN 10902. The exchange 1200 acquires a free channel of the high-speed multiplex leased line 1000 and calls the exchange 1100 at the large-scale enterprise spot. The exchange 1100 calls the communication terminal 1400 on the called side. When the connection between the calling-side terminal and called-side terminal is completed, the exchange 1300 digitally compresses and sends communication information of the calling side and expands received information into analog data.  Consequently, no analog lease line need not be laid in the small- scale enterprise spot and an extension network can be constructed in an enterprise.
