Expansion cards
The basic systems are expanded by fitting out the expansion slots. The 2025/2045
mainboard contains 5 of these slots. An upgrade licence (2025
→
2045) enables
higher expansion limits (max. number of interfaces). The Ascotel 2065 mainboard
contains 14 expansion slots.
The expansion cards are the same for all Ascotel® IntelliGate® systems. In principle
any card can be used in any system (exception: The expansion card with two pri-
mary rate accesses (ISDN-02PRA) is not designed for Ascotel® IntelliGate® 2025).
However the number of interfaces enabled is determined in each case by the sys-
tem limits.
There are 3 types of expansion cards available for expanding the basic systems:
•
Trunk cards
•
Terminal cards
•
Special cards
