Peripherals
An Expansion KSU can support PIOU, PIOUS, RSSU and PEPU PCBs (see Table 2-6 for a list of
options).
PIOU or PIOUS
The PIOU/PIOUS provides one dedicated RS-232 port for Station Message Detail Recording
(SMDR) connection to a call accounting device and one of the following:
♦
a TTY/RS-232 port which can connect to a customer-provided VM SMDI or external modem
for remote maintenance, or to a local PC with DKAdmin
♦
connectors for an internal modem (IMDU) for remote maintenance and administration
RSSU
The RSSU provides one TTY/RS-232 port for a connection to a VM SMDI or customer-provided
external modem for remote maintenance, or to a local PC with DKAdmin. The RSSU does not
support SMDR or IMDU.
Any device that connects to the PIOU, PIOUS, or RSSU should not be considered a station and
does not affect the system’s station capacity.
1. Amplified page output (single zone, 3 watts, 8 ohms) on the PIOU and PEPU is not available on the DK40i
2. These functions are standard (built-in) to the DK40i Base KSU.
