System Modules and expansion cards

There are a number of modules which can be installed onto the Base Motherboard:

• Extension expansion card. This provides six extensions and a connector for a network expansion card,
ISDN or PSTN.
• PSTN expansion card. This card provides two analogue exchange lines.
• ISDN Expansion card. This card provides one ISDN2 interface. The same card is used for the network T
and the internal S bus. Links located on the ISDN Expansion card must be relocated to change the
interface from T to S bus operation.
