Expansion Cards and Modules

A full complement of expansion cards consisting of trunk cards, subscriber cards
and special cards connects the system with its environment, or enables special
functions.
The trunk cards contain interfaces for connection to the analogue or digital public
network (ISDN), or for networking PBX systems to create a private telephony net-
work.
Subscriber cards are used for connecting voice and data terminals such as:
• Office system terminals
• DECT radio units
• Pocket Adapter
• Standard ISDN equipment
• Analogue terminals
• Fax machines
• Answering machines
• IVR and ACD systems
Special cards are used in the following cases:
• for voice transmission via an IP network
• the Ascotel Voice Mail System, mobile telephony (DECT) and full-duplex hands-
free mode
• for connecting one or two door intercom systems
The UPS-12V module ensures uninterrupted operation in the event of a mains
power failure. Ascotel can also be powered from a 12V back-up battery or the
DC-48V module, directly via the module. Both modules are optional and do not
take up an expansion slot.
The full spectrum of expansion cards and modules can be used for all the Ascotel
systems, within the system limits. As a result logistics at all levels are very simple.
