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 ASCII 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.

Network and terminal sides can be independently configured for ESF or SF and B8ZS or AMI. The T-SMART CSU will then automatically convert signals as necessary. The T-SMART CSU is fully compatible with AT&T TRs 54016 and 62411, ANSI T1.403 ESF standards and FCC Parts 68 and 15.

The Group Controller Unit (GCU) and Shelf Interface Unit (SIU) provide control access to large numbers of T-SMART CSUs in shelf applications.
