NETWORK ARCHITECTURE AND CALL PROCESSING SYSTEM

摘要

The Network Intelligent Peripheral (NIP) topology (100) of the invention includes a private ATM backbone WAN (105) and/or backup ATM WAN (105a) comprising one or more BPX ATM switches for linking three or more distinct LAN network sites (200a-200c). The ATM WAN (105)/back-up ATM WAN (105a) implements private point-to-point ATN links depicted as links (110a-110c) between the respective NIP LAN sites (200a-200c), respectively. The Hot Standby Network (106) is implemented as a backup network, for connectivity to the Monitoring Command System (115) as well as other System/Network management sites (120). Each NIP LAN site (200a-200c) comprises: a real-time call processing LAN, a provisioning LAN, and the Intelligent Peripheral LAN. Network latencies are minimized to meet the Statement of Necessary Requirements (SoNR) for real-time traffic, in particular that traffic which must traverse the WAN.
