 FORTE
155E Rack Mount Type integrated with advanced semiconductor
devices and microprocessors.
FORTE155E is a next generation
compact SDH multiplexer with the design to enhance
circuit density, and cut down on space requirements
making it ideal for installation in metropolitan
offices where space is scarce, or in outdoor cabinets
in remote areas.
The FORTE155 rack mount type supports four individual
Optical Multiplexers with 1+1 optical switching
protection feature. The equipment adapts four
lines of E1/T1 modules to provide 4/8/12/16 lines
of circuits, and also supports power redundancy
feature for reliable operation.
FORTE 155E uses a 19-inch chassis and can be mounted
on a 19-inch, 23-inch or standard ETSI ETR 300
019 rack. Apart from the subscriber line, which
will require setup by the users themselves, all
wires within the Shelf are ready-for-use. Dust
covers can be placed over unused slots. All subscriber
lines are linked by wire wrapping. RS-232 and
RJ-45 connectors are located at the lower right
corner of the shelf, which will provide CIT and
NMS interfaces for users.

Management System
FORTE 155E provides three different
types of management interfaces, by which field
operators may conduct system management functions
such as Provisioning, Performance Monitoring,
Loopback Test, and Alarm Management. Different
interfaces also allow for the configuration of
different settings, such as the Service Type of
E1/T1 Tributary Modules, the Line Code, and Frame
Format, etc..
• A Local Craft Interface (LCI) is provided
via the RS-232 connector.
• Management of the Local System, and Remote
product settings can be controlled through Panel
keyboards and the LCD panel control interface.
• A SNMP Network Management Interface is
provided through the RJ-45 connector.
• Provides a Network Management System (NMS)
with Graphical User Interfaces (GUI).
Field Operators can use notebooks or PCs as the
LCI, to connect to the NMS via RS-232, and conduct
Local Operation in a Menu Driven Mode. If a connection
is made through LAN, then the user may use the
GUI Interface to conduct system management.
