Component mounting rules
The component mounting rules mentioned in the previous chapters are listed here in
an overview:
• The interface cards can be used in all the card slots IC1...IC4.
• DSP modules are stackable and are fitted to the same DSP slot using spacer
sleeves.
• The interfaces are enabled sequentially when the communication server is started
up. The following rules apply:
– The number of interfaces actually enabled is determined in each case by the sys-
tem capacity (see "System capacity", page 60). If a limit value is reached, all the
interface cards or all the interfaces of the last card may not be enabled.
– The interfaces are enabled in accordance with their designation, starting with the
lower designations. This means that the terminal interfaces on the mainboard are
always enabled before those on the interface cards.

Connecting the communication server
There are two possibilities for connection to the telephone network and the terminal-
side cabling:
• Direct connection
• Indirect cabling via (main) distribution frame and any universal building cable instal-
lation (UBC) (see also Fig. 26 and Fig. 27).
