- ONE WALL
MOUNTING
HOLE
Mount the HESB to a wall or vertical surface in
accordance with the following steps:
1) Find a suitable location on the mounting
surface for the HESB.
2) Screw a 1.25inch panhead wood screw
into the mounting surface.
3) Hang the HESB from the screw in the
mounting surface.

11 NIGHT RINGING OVER EXTERNAL
ZONE PAGE (RELEASE 3)
11.00
In systems shared by two tenants, each
tenant’s CO lines can be assigned to night ring
separate PIOU external page zones (Figure 8-25).
This feature can also be used in one-tenant systems.
11.01
With shared systems, for example, tenant
l’s night ringing CO lines could be programmed to
ring PIOU external page zones 1 and 2, while
tenant 2’s lines could be programmed to ring zones
3 and 4. In non-shared systems, night ringing CO
lines can be assigned to ring all of the zones or just
selected zones.
11.02
The following programs must be used to
assign CO lines to ring selected PIOU page zones:
l
Program 78-1:
Assigns CO lines, tenant 1 and
tenant 2, that will night ring over PIOU external
page zones.
l
Program 15-5:
Assigns CO lines to tenant
tenant 2. Lines are initialized as tenant 1.
1 or
l
Program 77-1 (LEDs
10 w 13): Assigns tenant 1
and tenant 2 CO lines to night ring specific PIOU
external page zones.
l
Program
39: Assigns appropriate
q
, m
(tenant I), and m (tenant 2) buttons to elec-
tronic and digital telephones.
NOTES:
I. See Paragraph 6 and Figure 8- 15 for PIOU
zone paging ins talla tion instructions.
2. Any sta tion can pick up CO lines that night
ring over external page zones by dialing

12 DATA INTERFACE UNIT
INSTALLATION (RELEASE 3)
12.00 General
12.01 Release
3 provides two types of Data Inter-
face Units (DIUs) that enable digital telephone
users to simultaneously transmit and receive data
on the same PDKU station port and wire pair while
communicating on a voice call. One unit, called the
integrated DIU (PDIU-DI), becomes part of the
digital telephone, replacing the telephone’s base;
the other unit, is a small self-contained unit called
the stand-alone DIU (PDIU-DS). Each DIU is
powered by the PDKU it is connected to; therefore,
no external power is required.
12.02 Both DlUs can be connected to standard
Electronic Industries Association (EIA) RS-232
asynchronous serial data devices. EIA devices are
divided into two categories: data communication
equipment (DCE) and data terminal equipment
(DTE). Common DCE devices are modems and
some printers; common DTE devices are personal
computers, ASCII terminals, and some printers.
The PDIU-DI operates like a DCE and connects
directly to DTE devices using standard RS-232
cables. Depending on how its internal jumper plugs
are configured, the PDIU-DS can either operate
like a DTE and connect to DCE devices; or operate
like a DCE device and connect to a DTE device. In
most applications, DTE and,DCE devices exchange
data between each other via the standard RS-232
cable connection.
