DESCRIPTION

Loop Telecom's Loop-E 1500 FE1 CSU/DSU Product series provide an economic solution to E1 network access cost, when only a partial of 31 DS0 channels in needed. This product series support HDB3 (High Density Bipolar 3) coding and provide continuous error checking, performance polling, and in-service diagnostics. With DTE port operating from 56 Kbps to 1984 Kbps, Loop-E 1500 FE1 CSU/DSU enables users to interconnect LANs and WANs, CAD and CAM, video conference, mainframe hosts, and others.

Loop-E 1500 FE1 CSU/DSU series support local control and diagnostics using 2-line by 40-character LCD and keypads on a shared central controller card. This enables users to execute in-service diagnostics and fault isolation. Each plug-in card also provides 10 LEDs for both line side and DTE side status indicators. Using SNMP Network Management Systems and Telenet connection on the shared Controller card, user can remotely control and diagnose Loop-E products from any where. Using Ethernet, Slip, Telnet, or SNMP, controller cards from different racks can be daisy chained and managed from a central network manager.
