HP J2905B ISDN BRI S/T and U Interface Module

The HP J2905B mainframe module adds ISDN testing to the HP Internet Advisor for a fully integrated monitoring simulation, call placement and BERT solution. Basic S/T and U ISDN problems can be quickly isolated. With this module the portable and integrated HP Internet Advisor is a multi-protocol, multi-interface protocol analyzer that connects to the ISDN interface: basic rate S/T and U. You can quickly isolate network problems using the complete, real-time ISDN decodes with summary and detailed displays (including full information elements) and extensive D-channel statistics.

HP Internet Advisor supports 14 different ISDN switch and country variants; extensive decodes on the user data channel allow LAN interconnect problems to be solved quickly.

With the Internet Advisor comes extensive triggering, filtering and searching which allow you to view only the information that is important to the problem at hand. Problems are solved quickly using Internet Advisor's many pre-written tests and its intuitive user-interface. Verify the integrity of the link to carry data with complete BERT testing. Check network connectivity with pre-written simulation tests. Unattended remote control allows network experts to remain at a central site rather than travel to a remote location to solve tough network problems, saving time and money.
