Product Overview

The T-SMART CSU provides in-service monitoring of both ESF and SF (D4) networks for early detection of developing problems.

Both network and terminal sides are monitored. The performance results of the last 24 hours, stored in 15-minute intervals, can be accessed with an ACSCII terminal. The T-SMART can automatically dial up, via modem, your network management center to report alarm conditions. Problems can be further isolated and diagnosed using user-selectable loopback tests and a built-in test signal generator.
