2.2 Functional and physical architecture of the iPBXs
2.2.1 Aastra XD
The architecture of Aastra XD is as follows:
• A main cabinet including:
- one (simplex configuration) or two main UCV-D cards (duplex configuration), the
core of the iPBX, mainly perform tasks such as process management, switching
and interfacing with the management devices; it includes:
- the basic equipment of an iPBX
- management ports
- an IUCV-D card which supports the system’s external connections
- if necessary, expansion cards. These cards interface with the communication
devices and connected networks. They are added to increase the connection
possibilities of:
- One or two ADS350XD or ADS300XD power supply modules:
- one (ADS350XD or ADS300XD) power supply module and one VADS ventilation
module, in case of simplex configuration
- two ADS350XD or ADS300XD power supply modules, for a simplex
configuration with secure power supply, or duplex
• One or two expansion cabinets, optionally each linked by a wire to the main cabinet
with:
- one card (simplex configuration) or two RUCV-D cards (duplex configuration)
installed instead of UCV-D card(s)
- additional expansion cards
- one or two ADS350XD or ADS300XD power supply modules:
- one (ADS350XD or ADS300XD) power supply module and one VADS ventilation
module, in case of simplex configuration
- two ADS350XD or ADS300XD power supply modules, for a simplex
configuration with secure power supply, or duplex
