Phones (Figure 4-31, Figure 4-32)
1. Remove the integrated wall/desk bracket from the bottom of
the phone. Refer to Figure 4-31.
- From the top, right-hand side of the wall/desk bracket, pull
up slightly until the corner lifts up.
- Gently pull the bracket to the right and pull up. This
allows the left-hand side to release.
2. Break off one of the wall-mount hookswitch tabs located on
the bracket.
3. To allow for easier installation, gently push a small flat-head
screwdriver in the slot below the hookswitch until the handset
hanger pushes up.
There will be a slight snap as it releases.
4. Insert the wall-mount hookswitch tab in the slot below the
hookswitch. The tab should be pushed in until it’s flush with
the base (Figure 4-32).

1. After removing the integrated wall/desk bracket from the bot-
tom of the phone. (Figure 4-31), break off the 1 1/2” section of
the bracket as indicated in Figure 4-31 and discard this piece.
After breaking this section off, the bracket can not be
used in the future as a desk stand.
2. Depending on your installation, attach the wall-mount kit’s
plastic bracket to either a metal wall plate or directly to the
wall (Figure 4-33).
3. Insert the telephone’s line cord from the 625 modular jack
through the plastic bracket and into the phone.
4. Place the telephone on top of the plastic bracket on the
hook provided.
The hook on the bracket slides into the slot on the
back of the phone.
5. Push the bottom of the phone until both the left and right
sides snap into place.
To remove the phone from the wall-mount bracket if
needed, push in on the left and right sides of the bracket
while lifting the phone up off the bracket.

DATA OVERVIEW
The System’s Data Communications Capabilities
(Figure 5-1)
The system provides data device interfaces for data communi-
cations. Using data devices allows a network to share a limited
number of business resources such as modems, printers, and
PCs. The systems DCI devices can switch asynchronous RS-
232-C data at speeds from 300 to 19.2K.
There are currently three types of data devices available: DCI-
A, DCI-B and the 3-DCI Module.
DCI-A
The DCI-A is a single port data module that provides a serial
RS-232-C port. The DCI-A is installed in a key telephone, but
has a unique extension number. DCIs can be installed in any
Super Display or 32-Button Display telephone within the P/N
926xx/922xx series of phones. With the i-Series phones (P/N
927xx), the DCI can only be installed in the Super Display, 28-
or 34-button key phones. Each DCI-A requires one data (soft-
ware) port, which has the same number as the DSTU station
port. You can install up to 72 DCI units – one in each telephone.DCI-B
The DCI-B is a single port data module that provides a parallel
(Centronics type) port. The DCI-B is installed in a key tele-
phone, but has a unique extension number. DCIs can be
installed in any Super Display or 32-Button Display telephone
within the P/N 926xx/922xx series of phones. With the i-Series
phones (P/N 927xx), the DCI can only be installed in the Super
Display, 28- or 34-button key phones. Each DCI-B requires one
data (software) port, which has the same number as the DSTU
station port. You can install up to 72 DCI units – one in each
telephone.
3-DCI Module
The 3-DCI Module is a stand-alone data module which pro-
vides three RS-232-C serial ports, each port requiring one sys-
tem data (software) port. The 3-DCI derives power and signal-
ing from one 8DSTU circuit. Each cabinet can support three 3-
DCI Modules. With the 28i system, this can provide up to 9
ports. On the 124i system, you can install up to nine 3-DCI
Modules per system providing 27 ports.
Continued on next page . . . 
						

							5. Data
and SMDR5-3
DATA OVERVIEW
The 3-DCI Module uses a single digital station port on a DSTU
PCB. The module’s data ports have the same numbers as the
DSTU PCB port andthe next two DSTU PCB ports. When you
plug a 3-DCI into a DSTU port, the system disables the data
capabilities for any devices connected to the next two consecu-
tive ports. For example, if you plug a 3-DCI into port 1, you can
plug in keysets in ports 2 and 3, but you cannot plug DCI units
or another 3-DCI Module into ports 2 and 3. The data ports for
the 3-DCI plugged into DSTU port 1 are numbered 1-3.
DCI-L1 (Future Item)
The DCI-L1 will supply two additional channels to the single
channel i-Series phones.
If an i-Series phone has a DSS Console and a DCI-L1 (analog)
module installed, the DSS Console must have a separate
AC/DC adapter, even if it is the only DSS connected to the
phone.

DCI-A AND DCI-B UNITS
Using the DCI-A and DCI-B Units (Figure 5-2)
The DCI is a single port DCE data module that installs in a
multibutton telephone. DCIs can be installed in any Super
Display or 32-Button Display telephone within the P/N
926xx/922xx series of phones. With the i-Series phones (P/N
927xx), the DCI can only be installed in the Super Display, 28-
or 34-button key phones. 
The DCI provides the system with the ability to share common
data communications resources such as printers, modems or PCs
in a data network. The DCI can switch data at speeds from 300
to 19.2 K baud. Refer to Data Communications Interfacein the
software manual for additional details.
The DCI also provides remote (via modem) and on-site mainte-
nance capability. This capability includes reports on system
alarms, port identification, PCB status and other system config-
uration data. For maintenance purposes, you should always
install one DCI unit or a 3-DCI Module in every system.

DCI-A AND DCI-B UNITS
Installing the DCI Unit (Figures 5-3 through 5-9)
You can only install a DCI Unit in a Super Display or 32-
Button Display telephone within the P/N 926xx/922xx series of
phones. With the i-Series phones (P/N 927xx), the DCI can
only be installed in the Super Display, 28- or 34-button key
phones.
1. Turn the telephone upside down and remove the directory card.
2. Remove the screws that secure the telephone base or DCI
cover, depending on the model of the phone.
3. Remove the telephone base or DCI cover.
