The ADTRAN
®
TSU 120
™
and TSU 120e
™
are
modular, full-featured T1/FT1 multiplexers
designed to support a wide range of end-user
applications. Equipped with both a synchro-
nous V.35 DTE interface and a DSX-1 PBX port,
the TSU 120/120e supports applications
combining digital voice and high-speed data.
As interface requirements increase, the flexi-
bility of the TSU 120/120e benefits the user
with modularity through its expansion slot.
The TSU 120/120e provides complete moni-
toring and control of the T1 network with
embedded simple network management
protocol (SNMP) provided through a SLIP
interface. The TSU 120e also has a built-in
10Base-T Ethernet interface. To support critical
data applications, the built-in V.35 interface on
the TSU 120e can be converted to provide dial
backup functionality during T1 failure condi-
tions. This feature is supported by the interface
and is available using an optional V.35 “Y” cable.
Support for future growth, through the
unit’s single expansion slot, is a key feature of
the TSU 120/120e. The ability to combine many
types of plug-in and plug-on modules provides
extensive combinations of voice and data inter-
faces. Several data modules are available for
single and dual-port access to Frame Relay,
DDS or Basic Rate ISDN services provided over
T1 facilities. Voice modules are also easily inte-
grated allowing access to analog voice circuits
or additional PBX connections. As a fully
functional T1 multiplexer, the TSU 120/120e
supports all mixed-mode networking applica-
tions providing termination for circuits
containing voice, data and video channels.
Configuration and management of the
TSU 120/120e is available through a variety of
methods. The TSU 120/120e supports SNMP
with Gets, Sets and Traps functionality through
a built-in agent. ADTRAN MIBs support
management for the TSU 120/120e and all
installed expansion modules. For access to
SNMP features, the TSU 120e has both a
10Base-T Ethernet and a SLIP (EIA-232) connec-
tion, while the TSU 120 has a SLIP interface
only. In addition to SNMP, the unit utilizes the
management capabilities found in optional
software products from ADTRAN. For Windows-
based management, the TSU 120/120e is
compatible with the popular T-Watch PRO
™
software package. 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.
