High Density Legacy Line/Trunk Blades
Major legacy line/trunk blades used in SV8100/SV8300 are provided with main
blade + daughter blade architecture. When the main blade is mounted only in an
initial supply, line/trunk interfaces can be easily expanded by adding the
daughter blade. The maximum number of ports for the line/trunk blades is 8/16
ports with daughter blade, respectively. This allows the physical system size to
be compact.
Universal Blade Slot (19" Chassis)
A 19" Chassis is used for legacy line/trunk blades. One 19" Chassis provides six
universal slots and one expansion slot. Also, the universal slots can be used for
special application blades without complicated limitation. This makes easy
quotation and installation.
Easy Installation (Front Cabling and Enhanced O&M Tool)
Cable connectors (RJ-45 or RJ-61) are located on the front panel of each
chassis and blade. It increases efficiency of the cabling work. Also, PCPro
provides an enhanced user interface. A Quick Setup tool provides easy setup
(system data programming) for a basic system configuration in shorter time.
Remote Unit over IP with Survivability (SV8300 only)
The SV8300 can provide Remote Unit configuration, main site and remote
unit(s) through IP network. The main unit controls call processing and service
features access for station users located in both main unit and remote unit(s).
When the remote unit cannot be connected with main unit due to IP network
failure or main unit failure, the remote unit initializes the system and re-starts
operation by its own CPU (survival mode). In the survival mode, almost service
features are provided to the station users accommodated in the remote unit.
When IP network/main unit is recovered, the remote unit can be restored to
normal mode with system reset by automatic or manual operation (Selectable
by system data setting).
