Presentation of Aastra X series products

Aastra X series products include a set of homogeneous and scalable systems used to
manage 8 to 1000 subscribers, based on a single software package and a range of
subassemblies (cards) common to all products in the range.
Aastra Duplicated PBX (Aastra XD) is a secure upgrade of Aastra XS/XL PBXs. It is used
to secure the functions of the iPBX by duplicating the CPU card, some integrated services
and power supply. This security guarantees 100% iPBX resources availability.
Aastra XD exists in form of one, two or three cabinets used to manage 8 to 1000
extensions. Like the other products, it is based on a single software application and a
range of subassemblies common to all Aastra products.
Aastra XD can be configured in three different ways:
• Simplex configuration, comprising a single UCV-D CPU card in the main cabinet, a
single RUCV-D card in the expansion cabinet(s), and a single power supply module
per cabinet. In this case, none of its elements is duplicated.
• Simplex configuration, with secure power supply, comprising a single UCV-D CPU card
in the main cabinet, a single RUCV-D card in the expansion cabinet(s), and two power
supply modules per cabinet.
• Duplex configuration with two UCV-D CPU cards in the main cabinet, two RUCV-D
cards in the expansion cabinet(s), and two power supply modules per cabinet.
The Aastra X series is used for connecting to traditional analogue or digital
communication networks or using the IP protocol.
It provides a high level of integration of telephone services (messaging, IVS, answering
machine, announcements, etc.) and remote management (IP, HDLC, downloading).
It is based on total operation (monitoring, configuration, downloading) of the iPBXs
through remote management.
Aastra X series comprises four products:
• Aastra XD (AXD)
• Aastra XL (AXL)
• Aastra XS (AXS)
• Aastra XS12 (AXS12)
• Aastra XS6 (AXS6)
These iPBXs are differentiated mainly by their management and switching power:
• 1000 physical extensions for an AXD
• 1000 physical extensions for an AXL
