Cabinet, which is made of plastic.
PS38 Power Adaptor is a Switched Mode Power Supply (SMPS) operating at mains
voltage. Receiving 220 VAC over the mains, PS38CR generates –24 VDC and 8
VDC for the system and accessories as well as 64 Vrms ring signal. The output of
8 VDC is also regulated to 5 VDC by the MB26s motherboard.
PS38 Power Adaptor can be directly plugged in the mains socket on the wall. The
connection to the system is established via the built-in cable that is directly
connected to PS38CR. The 8-pin RJ plug at the end of this cable is to be attached
to the 8-pin RJ socket (named POWER) on MB26s motherboard.
The pin-out of the POWER socket on MB26s motherboard is illustrated in the
