2.3 Power Supplies
2.3.1 Power supply modules
Two optional DC power supply modules are available in addition to the power
supply via the 230 V mains network:
• UPS-12V for the uninterruptible power supply from a 12V buffer or central bat-
tery
• DC-48V for the power supply from a 48V central battery
Each system can be complemented with a power supply module. This does not
take up an expansion slot.
2.3.2 Auxiliary Terminal Power Supply (ATPS)
The external Auxiliary Terminal Power Supply (ATPS) is used to increase the supply
power available for the terminals. It is required only for system expansions with a
large number of terminals with high power requirements (e.g. a large numbe of
DECT radio units without their own power supplies) (see also "Power supply-
related limits per system", page 597).
The ATPS power supply unit is powered by the 230 V mains.
It is not possible to use ATPS and a DC supply module at the same time. An exter-
nal UPS or an inverter is required to be able to ensure uninterruptible operation
when using an ATPS system.
2.4 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.
