CSU/DSU
DSU functionality integrated with an intelligent CSU in a compact package.
Support up to 2 customer equipment interfaces include E1 ICSU, serial DTE, router, and G.703 (co-directional).
Support SNMP Network Management Systems.Support In-band Management
Connection to LAN/WAN, CAD/CAM, or Hosts to E1 Network Services.
Local control and diagnostic via RS232 port or 2-line by 16-character LCD & keypad.Router - 10/100 BaseT auto selection.
Multicolor LED indicators.
Loop Telecom's Loop-E1500 CSU/DSU product series provide an economic solution to E1 network access cost, when only a partial of 31 DS0 channels is needed. Clear channel (32 DS0 channels) is also available. This product series support HDB3 (High Density Bipolar 3) coding and provide continuous error checking, performance polling, and in-service diagnostics. Customer equipment interface include E1 ICSU, serial DTE, Co-directional DTE, and router. With DTE port operating from 56 Kbps to 2048 Kbps, Loop-E1500 CSU/DSU allows users to interconnect LANs and WANs, CAD and CAM, video conference, mainframe hosts, and others. With router interface, users can connect LAN to WAN directly without additional bridge/ router.
Loop-E1500 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. An in-band management channel with GUI are available. The Loop-E1500 CSU/ DSU also provides multicolor LED indicators on the front panel. Using SNMP Network Management Systems and Telnet connection, users can remotely control and diagnose Loop-E products from anywhere.
