3.2 Expansion Cards
Basic systems are expanded by equipping the expansion slots with expansion
cards. This chapter describes how and when expansion cards are expanded,
moved and replaced.
The combination of card type and the the maxium expansion is determined by sys-
tem limits. The system and expansion limits of the various basic systems are
described in "Licence-related System and Expansion Limits", Page 3.18.
Expansion Card Types
There are three types of expansion cards: Subscriber cards, trunk cards and special
cards. An overview of the different cards with their interfaces can be found in
"Equipping the PBX", Page 4.17.
Expansion Card Slots
The 2025 / 2045 mainboard contains 5 expansion slots for expansion cards.
Depending on the licensing, only two (Ascotel 2025) or all of the slots (Ascotel
2045) are enabled. The 2065 mainboard contains 14 expansion slots (7 expansion
slots on either side of the processor card).
Expansion cards can be fitted to any expansion slot. Exceptions:
• On the Ascotel2025, only the first two expansion slots from the left can be
equipped (license dependent).
• On the Ascotel 2065 the system slot for the MPC-8260 processor card is in the
middle.
Unused expansion card slots are fitted with dummy covers (EMC).
Expansion Card Configuration Data
Configuration data consists of system configuration data and terminal configura-
tion data. All the configuration data is stored centrally in a non-volatile memory
on the Flash card. This means that configuration data is preserved whenever a
defective subscriber card or trunk card has to be replaced by a new one.
