An expansion cabinet can be connected to the main cabinet. This expansion cabinet is connected
thanks to a flexible wire, thus allowing the two cabinets to be stacked or to be mounted side by side. In
the case of wall mounting, the expansion cabinet can only be installed beside the basic cabinet.
This expansion cabinet has its own power supply unit and three expansion slots, which only accept
the following cards: LN16, LA16, LA8, LN8, LH8, LM8, LH16, DL8 and DL16.

positions of the expansion cards. It has an EEPROM memory connected to the UCV2S card through
the connection bus.
It includes a control interface for 3 equipment cards and 7 PCM trunks assigned to the 3 equipment
cards.
