The ADTRAN ESU 120e is a modular, full-featured E1/Fractional E1 multiplexer that supports a wide range of end-user applications. Providing a flexible data port and a G.703 Drop port, the ESU 120e supports international applications combining digital voice and high-speed data. For application flexibility, the ESU 120e can utilize most ADTRAN TSU family data modules in the single expansion slot. The embedded Simple Network Management Protocol (SNMP) allows for complete monitoring and control over the ESU 120e through both a SLIP and a 10BaseT Ethernet interface.

A key feature of the ESU 120e is the support of future growth through the unit's single expansion slot. End-user upgradeable expansion modules allow for the connectivity of up to four additional DTE devices. These expansion modules and plug-on modules allow for several interface port combinations, including the integration of Frame Relay over E1 facilities and the ability to implement dial backup in case of E1 line failure. To add to the unit's flexibility, an IP/IPX router module is available, allowing the support of integrated routing for branch office connectivity or Internet access. The large variety of available expansion modules allow the ESU 120e to tailor fit most any voice and data application requirements.
