Expansion with cards and modules

A basic system can be individually expanded using interface cards and system
modules. The number of available expansion slots depends on the basic system
(see "Interfaces", page 23).

Interface cards

Interface cards provide network interfaces and/or user-network interfaces or spe-
cial interfaces. Interface cards are further broken down into:
• Trunk cards
• Subscriber cards
• Options cards
On some cards the interfaces are partly configurable (S/T). This means that these
cards cannot be clearly assigned to any particular category. They are listed both
among the trunk cards and the subscriber cards.
Some of the interface cards are already being used on the Ascotel® 200; others are
exclusively for the Ascotel® IntelliGate® 150/300.
Interface cards are fitted into slots IC1...IC4 (see Fig. 8, page 24).
The interfaces are routed to the front panel using the Wiring Adapters (see "Wiring
Adapter", page 36).
The length varies depending on the type of interface card. For precise dimensions
see the Chapter "Technical Data", page 202.
