Loop Telecom's Loop-T2500 FT1 CSU/DSU series provides an economic solution to T1 network access cost, when only a partial of 24 DS0 channels is needed. This product series support Extended Superframe Format (ESF) which makes possible continuous error checking, performance polling, and in-service diagnostics. Customer equipment interfaces include T1, series DTE, and Router. With DTE port operating from 56 to 1536 Kbps, Loop-T2500 FT1 CSU/DSU allows users to interconnect LANs and WANs, CAD and CAM, video conference, mainframe hosts, and others.
Loop-T2500 FT1 CSU/DSU series support local control and diagnostics using 2-line by 16-character LCD display and keypads or RS232 console port. This allows users to execute in-service diagnostics and fault isolation. The multi-colored LEDs on the front panel provide both line side and DTE side status indicators. An in-band management channel with GUI are available. Using SNMP Network Management Systems or Telnet connection, users can remotely control and diagnose Loop-T products from anywhere. A GUI Windows based SNMP manager, LoopView, is available.
