ABSTRACT
The article presents information on the testing technique used for high-end IP-PBX systems. The test bed for IP-PBXs consists of two simulated sites, a headquarter and a remote office, connected by an IP WAN link. The network infrastructure at both sites consisted of Extreme Networks Summit 48 L2/L3 switch/routers. The IP-PBX vendors have the option of deploying their IP-telephony systems over the testing laboratory's network infrastructure, or else provide their own switch and router equipment. The vendors are also needed to provide their own power over Ethernet equipment to power their IP hard phones. A simulated IP WAN connects the headquarters and remote sites while a PacketStorm Hurricane 1800E Network Emulator is used to apply impairments simulating a typical PF LAN and a WAN link over the Internet. The headquarters and remote sites are PSTN-connected via T1 s, through an Adtran Atlas 800 central-office switch simulator. This connectivity is used to test T1-gateway failover and IP-to-PSTN re-routing scenarios.
