Installing the DCI Unit (Cont’d)
For 926xx and i-Series Phones:5. Using a flat-blade screwdriver, carefully pry out the filler piece
on the telephone base. This exposes the cutout in the base.

Connecting the DCI Unit (Figure 5-10)
1. Locate an available DDK connector in a station (B) block.
2. For the DDK connector chosen, cross-connect the associated
wire pair from the A or B block to the cross-connect block.
3. Install a modular jack for the DCI unit’s telephone within six
feet of the telephone’s location.
4. Run one pair of 24 AWG station cable from the cross-con-
nect block to the telephone’s modular jack.
5. Terminate the station cable WHT/BLU -...

3-DCI MODULE
Using the 3-DCI Module
The 3-DCI is a stand-alone three-port DCE data module. Each
port functions identically to the DCI-A unit. For example, you
can use it for networking printers, PCs and other data equipment.
Installing the 3-DCI Module(Figure 5-11)
1. Locate an available DDK connector in a station (B) block.
2. For the DDK connector chosen, cross-connect the associated
wire pair from the A or B block to the cross-connect block.

3-DCI MODULE
7. Ground the 3-DCI Module by connecting a 14 AWG ground
wire from the FG lug to a known earth ground.
8. Plug a line cord into the back of the 3-DCI Module and 
the module’s modular jack.
9. Plug the RS-232-C cables into the data device (e.g., PC serial
port or serial SMDR printer.

PROGRAMMING
Basic Programming
Note:For DCI units, the data (software) port number is the
same as the extension’s port number. DCI Modules use
the extension’s port number and the next two port num-
bers for data (software) port numbers.
0503 - DCI Extension Number
Assign an unused extension number to each DCI data (soft-
ware) port.
1006 - Programming Function Keys
Assign a data key (code 1029) at each keyset with a DCI unit.
1201 - DCI Setup
For each of the DCI sub-types (1-10 set in...

SOME TYPICAL DATA APPLICATIONS
Non-Dedicated 3-DCI Modem Pooling Network
(Figure 5-12)
In this application, a data port on the 3-DCI connects to a
modem which in turn connects to an available circuit on an
ASTU PCB. To place a data call through this network, an
extension user places a call from their PC or terminal using the
following ATDT dial  string:
ATDT + (first 3-DCI data port’s extension number) + (code
for accessing outside line) + (destination’s telephone num-
ber) + Enter...

SOME TYPICAL DATA APPLICATIONS
Dedicated 3-DCI Modem Pooling (Figure 5-13)
In this application, a data port on the 3-DCI connects to a
modem, which in turn directly connects to a dedicated outside
line. This application is also useful for incoming remote mainte-
nance calls. To place a data call through this network, an exten-
sion user places a call from their PC or terminal using the fol-
lowing ATDT dial  string:
ATDT + (destination’s telephone number) + Enter
For example: ATDT 1...

SOME TYPICAL DATA APPLICATIONS
3-DCI Data Network(Figure 5-14)
This application uses all three data ports on the 3-DCI Module
for various data applications. To access a device, an extension
user just places a data call to the 3-DCI port’s extension number.
