Ascotel IntelliGate 2025/2045/2065
Part 1 Telecommunication system Ascotel IntelliGate 55
2.2 Expansion cards, modules and auxiliary power supply
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 digital and analogue voice and data ter-
minals such as:
•Office System terminals
• DECT radio units
• Pocket Adapter
• Standard ISDN equipment
• Analogue terminals
•Fax machines
• Answering machines
•
External Voice Mail interfaces
Special cards are used in the following cases:
• Networking Ascotel systems via an existing private IP data network
• the Ascotel Voice Mail System, mobile telephony (DECT) and full-duplex hands-
free mode
• for connecting door intercoms
The UPS-12V module ensures that the system is able to operate without interrup-
tion in the event of a 230 V mains failure. Ascotel IntelliGate can be powered by
a 12V backup battery via the module. The DC-48V module is used to power the
PBX from a 48V central battery. 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 Ascotel
IntelliGate systems
(including rack versions), within the system limits (exception,
see "Expansion cards", page 583). As a result logistics at all levels are very simple.
