FE1 CSU/DSU
DSU functionality integrated with an intelligent CSU
Loop Telecom's SNMP Network Management Systems
Connect LAN/WAN, CAD/CAM, or Hosts to 2 Mbps E1 Network Services
Optional GUI NMS LoopView
Compliance with ITU-T G.703, G.704, G.706, G.732, G.736, G.823, ETSI ETS 300420, ETS 300419
Loop Telecom's LOOP-E1200 FE1 CSU/DSU series provides an economic solution to the E1 network access at a fractional cost. The series utilizes only part of 31 data channels and users pay only a fraction of full E1 charges. The LOOP-E1200 FE1 CSU/DSU series supports HDB3 (High Density Bipolar 3) coding and provides continuous error checking, performance polling, and in-service diagnostics. The versatile LOOP-E1200 FE1 CSU/DSU series provides up to four sets of DTE equipment operating rates from 56 to 1984 Kbps and one Drop and Insert DTE operating at E1 (2048 Kbps) to be connected directly to the E1 network services. The series enables users to interconnect LANs and WANs, CAD and CAM, video conference, mainframe hosts, etc..
LOOP-E1200 FE1 CSU/DSU series supports local control and diagnostics with 2 by 40 characters LCD display and keypads. The series enables users to configure the unit, execute in-service diagnostics, and monitor network status and availability. LOOP-E1200 FE1 CSU/DSU series also provides LED status indicators. Loop Telecom supports SNMP by Loop Telecom's SNMP Network Management System to remotely control and diagnose LOOP-ETM products from anywhere in the network. In addition, Loop Telecom also provides an optional Windows based GUI network management system.
Ordering Information
Where
= 1 for no D&I, 2 for D&I port y = 2 for 2 DTE port, 4 for 4 DTE port DTE = 22 for V.35 DTE interface with DB25 connector
33 for EIA530 DTE interface ww = 75 for 75 ohm BNC E1 interface 120 for 120 ohm twisted pair E1 interface
PP = DC for 24 - 48 Vdc AC for 100 - 240 Vac, 50/60 Hz (For AC choose an appropriate power cord)
Example: Loop-E 1201-2-22-75-DC = For model 1200 with no D&I port, 2 DTE ports, V.35 DTE interface with DB25 connector, 75 ohm BNC E1 interface, no SNMP option, DC power.
