Loop-E1200
FE1 CSU/DSU Series
Description
Loop Telecom's Loop-E1200 FE1 CSU/DSU
series provides an economic solution for E1
network access at a fraction of the cost
elsewhere. This series utilizes only parts of the
31 data channels and users pay a fraction of
full E1 charges. The Loop-E1200 FE1
CSU/DSU series supports High Density Bipolar
3 (HDB3) 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 with 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. This series
enables users to interconnect LANs and WANs,
CAD and CAM, video conferencing, mainframe
hosts, and more.
Loop-E1200 FE1 CSU/DSU series supports
local control and diagnostics with a 2-line by
40-character LCD display and keypads. The
series enables users to configure the unit,
execute in-service diagnostics, and monitor
network status and availability. The Loop-
E1200 also provides LED status indicators. It
supports SNMP network management to
remotely control and diagnose Loop-E products
from anywhere in the network. In addition, Loop
Telecom also provides an optional Windows
based GUI network management system called
LoopView.
