Integration of packet switching service in ISDN
H. Yunoki, Y. Yamatani, T. Nara · 2003
The integration method of packet switching and circuit switching in the actual implementation of ISDN is considered. The advantages of packet-switching subsystem architecture introduced in Fujitsu's digital-switching system FETEX-150 are shown, from the viewpoint of a practical and flexible ISDN implementation. A practical three-stage approach to meet the growing ISDN packet traffic services is proposed.>
