●

The ETU01A single port stand-alone DSU/CSU provides our

best digital access solution for E1 and Fractional E1 network

services termination. A DTE device may be linked to an

ETU01A at data rates of 56Kbps to 2048Kbps. The ETU01A

features user replaceable dataport modules for a number of

interface standards; including Ethernet bridge, router, V.35,

X.21, RS-530, RS-449, G.703 64Kbps Co-directional and RS-232.

The ETU01A supports local control and diagnostics via LCD

display, keypad and LED status indicators located on the front

panel as well as via a menu driven RS-232 console port in

conjunction with a standard terminal.

These features enable users to easily configure the unit,

execute the in-service diagnostics and monitor the network

status. The ETU01A provides optional SNMP (Simple Network

Management Protocol), which allows the user to remotely

control, diagnose and monitor the system using industry

standard SNMP protocol, our proprietary MIB-II, and any

network management software.
