Optimised for Utility, Dedicated and Corporate Networks that require
high reliability in all systems relating to service delivery
Flexibility achieved through modular product architecture and
distributed power supplies
Broad range of subscriber interfaces covering high/ low speed data,
Ethernet and Voice ( e.g. V.35, X.21, V.24, 2/ 4-wire VF, E& M)
Dynanet
In primary access networks, there are
needs for various services. A broad
family of different interfaces with
varying capacities is required.
Dynanet, a flexible product family for
primary access networks provides
the following within its portfolio to
meet these challenges:
• DM2+ - 2Mbit/ s multiplexer
• DN2 - 2Mbit/ s cross-connect
• DB2 - 2Mbit/ s branching
equipment
• DIU - Data Interface Units
• VF - Voice Frequency interface
units
• DF2-8 & 34 – 2, 8 or 34Mbit/ s
optical line equipment
• DM8 & DM34 – Higher order PDH
• CO2, 8 & 34 - Changeover
Equipment
• SHDSL Modems – TDM SHDSL
copper line equipment
General Features
• DM2+ - A dynamically controllable
primary multiplexer utilising
Dynanet channel unit selection
• DN2 - A cross-connect equipment
with drop/ insert and multiplexing
capabilities, supporting up to 40 x
2Mbit/ s interfaces
• DB2 – An equipment family that
offers a wide range of different
branching and drop/ insert
functions. Typically, the DB2 is
used in private chain, tree or ringshaped
networks
• DIU – cards that cover the most
frequently used interfaces to data
terminals and mainframes ( e.g.
V.35, V.11, V.24/ V.28, X.21,
Ethernet and G.703)
• VF - subscriber and VF interface
units provide interfaces to the
2Mbit/ s transmission systems with
the Dynanet product family
• Higher order & optical equipment
– equipment that provides digital
signal transmission ( electrical or
optical) at bit rates of 2, 8 and
34Mbit/ s
• Changeover – equipment to
provide an alternative
transmission path in case of a line
failure ( the protection is 1+ 1 all bit
rates 2 to 34Mbit/ s)
• SHDSL Modems - data
transmission over twisted copper
pairs, typically providing
n* 64kbit/ s access to digital trunk
networks, either transparently or
in a G.704/ 2Mbit/ s frame structure
Flexible Installation
The Dynanet installation concept
offers flexible installation options in
wallmounting cases ( 4-and 8-slot
subracks) and 19� racks. The units
can be placed freely in any vacant
unit space also of other applicable
Dynanet units, so flexibility of the
configuration can be increased.
Customer benefits
The high reliability of Dynanet is
achieved through a high level of
integration, strict design rules and
careful component control. The
equipment MTBF values have been
increased and field reliability
statistics show actual reliability to
be even higher than the precalculated
values.
