ETU-01A: G.703/G.704 (E1) Converter with SNMP

1245486

The ETU01-A provides an economic digital access solution for E1 and Fractional E1 network services. A DTE device may be linked to an ETU01-A at data rates of 56Kbps to 2048Kbps. The ETU01-A features user replaceable dataport modules for a number of interface standards including V.35, X.21, RS-530, RS-449, and RS-232. The ETU01-A supports local control and diagnostics via LCD display, keypad and LED status indicators located on the front panel as well as via an 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 ETU01-A provides optional SNMP ( Simple Network Management Protocol ), which allow the user to remotely control, diagnose and monitor the system.
