I. SYSTEM DEFINITION
DS200 series exchanges are TDM based IP enabled communication systems. The systems
have distributed processor structure. The TDM switching part is based on different interface
boards and relevant protocol implementations on these relevant interface boards. Therefore,
the system's TDM structure is a modular structure, thus the system TDM capacity can be
increased by simply adding desired boards to the system.
The IP structure, on the other hand, is a software based structure. The IP capabilities of the
system come embedded on the main CPU and can be activated by the appropriate licensing
options. Therefore except for the media gateway channels no additional hardware is required
for the IP channels.
The DS200 series systems have different software options with different capacities. Below is
the complete family of DS200 series systems:
System Name Max Capacity
DS200M 144 TDM + 750 IP ports
DS200S 224 TDM + 750 IP ports
DS200 1344 TDM + 750 IP ports
DS200L 32000 TDM + 5000 IP ports
I.1. DS200
DS200 is a large-capacity telephone branch exchange, whose capacity can be extended to
672 lines and to 1344 lines, for three-rack and six-rack structures, respectively. The system
supports maximum 750 IP ports. Due to its distributed CPU structure, it is a very reliable and
flexible communication system, which is open to development.
DS200 can be configured in two different mechanical structures, namely wall or cabinet type:
The wall-type DS200 can be configured in two structures: the single-rack type (with cover)
which can be extended to a maximum of 224 lines, and the two-rack type (with cover) which
can be extended to a maximum of 448 lines. As for the cabinet-type DS200, it can be
configured in the following structures:
-
Single-rack (224 lines at the maximum),
-
Two-rack (448 lines at the maximum),
-
Three-rack (672 lines at the maximum),
-
Four-rack (896 lines at the maximum),
-
Five-rack (1120 lines at the maximum),
-
Six-rack (1344 lines at the maximum)
In that structure, the system can reach a capacity of six racks by the use of two cabinets.
The figures below illustrate general appearances of the wall-type DS200 system and the
cabinet.
