ESU 120e
E1/FE1 Multiplexer
The ADTRAN ESU 120e ™ is a modular, full
featured E1-Fractional E1 Multiplexer that
supports a wide range of end-user applica-
tions. 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 upgradable
expansion modules allow for the connec-
tivity 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.
The unit has several built-in test func-
tions for testing and trouble shooting the
ESU 120e and the E1 circuit. Users can
effectively isolate problems within the
E1 circuit by utilizing standard loopback
tests, DTE tests, network interface tests
and test patterns found in the ESU 120e.
For additional troubleshooting, the unit
supports external test equipment through
bantam jack access. In case of an E1 failure
or other major unit or network alarms, the
ESU 120e supports SNMP Traps and Alarms
to the host workstation and, if necessary,
dial-outs to pagers.
The configuration and management of
the ESU 120e is available through a variety
of methods. The ESU 120e supports SNMP
with Gets, Sets, and Traps functionality
through a built-in agent. ADTRAN MIBs
support management for the ESU 120e
and all installed expansion modules. For
access to SNMP features, the ESU 120e
has both a 10BaseT Ethernet and a SLIP
connection. In addition to SNMP, the unit
utilizes the management capabilities
found in optional software products from
ADTRAN. For Windows
® 95 or NT, the
popular T-Watch PRO ™ software package
facilitates easy configuration and monitoring
of the ESU 120e. For more complex network
management systems, ADTRAN’s
ADVISION
™ operates on an SNMP
enterprise management system such as
HP OpenView
® and provides full GUI
configuration and control via SNMP.
