The throughput test accommodates variable test duration times, data patterns, and speeds in order to determine the sensitivity of network devices such as modems, frame relay access devices
, hubs, switches, and routers.--Fluke Corp.
Direct local management interface (LMI) sourcing by a frame relay access probe insures that remote diagnostic service points remain accessible even if the adjacent frame relay access device
(FRAD) or router is down.
"Since the network connectivity from merchants often involves multiple sites, communications lines and frame relay access devices
(FRADs)," says David Weick, a senior network engineer at Concord, "we have to narrow down which lines are candidates for improvement.
It was one of the first companies to develop Voice over Frame Relay access devices
(VoFRADs) and the only company in the world to successfully install thousands of VoFR devices for many telecommunications companies, banks, and others, collectively having hundreds of POPs.
