PIOU/PIOUS (DK16) so that maintenance and
programming can be administered internally or
externally from desktop personal computers or
terminals connected to Integrated Data Inter-
face Units (PDIU-DIs).
NOTES:
1. An external modem is required for Remote
Maintenance if a QSMU is installed on
DK8, or if an IMDU is not installed on DK16
PIOU or PIOUS. The IMDU has a built-in
maintenance channel for remote
connection; however, an external modem
requires a CO line or standard telephone
port (Figures 2 and 3).
2. The DK16 PIOU or PIOUS can only be
installed in the Expansion Unit.
4 TERMINAL/MODEM INSTALLATION
4.01 DK8 and DK16 provide customers with a
number of Remote Administration and Mainte-
nance configuration options:
•
A customer-supplied maintenance terminal can
be connected to the system TTY port (DK8
QSMU, or DK16 PIOU or PIOUS) via an exter-
nal modem either locally (Figure 5) or remotely
(Figures 2 and 3).
•
With the DK16, the IMDU modem (300 or 1200
baud full-duplex) can be connected to the DK16
PIOU or PIOUS to allow system programming
and testing to be accomplished from a remote
location (Figure 4).
•
Instead of a modem or terminal, a Stand-alone
Data Interface Unit (PDIU-DS) can be con-
nected to the TTY port on the QSMU (DK8) or
