Digital Communications Systems
The Analog Terminal Interface
The ATI-D-1PT is a multipurpose, on-premise accessory for the digital communications system that enables you
to connect IST devices to a digital station board. The ATI-D-1PT supports a wide variety of IST equipment such
as 500 and 2500-type telephones, cordless telephones, answering machines, FAX machines, data modems, and
analog voice mail systems. It will accept both tone (DTMF) and pulse (rotary) dialing from these devices.
CAUTION
The ATI-D-1PT by itself does not support any off-premise service. Never connect the ATI-D-1PT to a
TELCO line unless you have installed an OPX long loop adapter. (Refer to the installation section of this
document for OPX long loop adapter installation instructions.)
The ATI-D-1PT unit contains an internal ring generator and telephone circuitry that supports one IST input.
Modular connectors allow for quick hookup to the digital station port and the IST device(s).
The ATI-D-1PT supports a maximum ringer equivalence number (REN) of 2.0, allowing it to support more than
one IST device, if they are bridged. Check the REN number of the IST equipment you connect so as not to exceed
the capacity of the ATI-D-1PT.

Connecting The Equipment
Connect the cabling to the ATI-D-1PT as shown in the diagram on the next page.
CAUTION
Be careful when connecting the wiring between the common equipment and the ATI-D-1PT. Be sure to
connect the digital station port to the COMMON EQUIPMENT (KSU) jack on the ATI-D-1PT. Damage
to the ATI-D-1PT could occur if this wiring is connected to the IST jack.
While a grounding wire is not required for operation, one is desirable for decreasing radio frequency interference
and electrostatic discharge susceptibility. The ATI-D-1PT has a grounding stud for this purpose. Connect a #10 or
#12, insulated, solid copper wire between this ground stud and an earth ground.
Checking The Installation
Use a voltmeter to check for the presence of voltage on the ATI-D-1PT IST jack.
1. Be sure the wiring between the ATI-D-1PT and the common equipment station ports is properly installed.
2. Measure for DC voltage on the IST jack:
•Measure between TIP leads and common equipment grounding stud.
•Measure between RING leads and common equipment grounding stud.
•Measure between TIP leads and RING leads.
The measured voltage must be within following limits (with the IST device on-hook):
Measurement Voltage
Tip to Ground -1 to +1 VDC
Ring to Ground -27 to -38 VDC
Tip to Ring +28 to +37 VDC
(The TIP lead is positive with respect to the RING lead.)

Connecting The ATI-D-1PT

Installing An OPX Long Loop Adapter For Off-Premise Service
The ATI-D-1PT is an on-premise device—you must use an OPX long loop adapter if you wish to adapt the
ATI-D-1PT to support an off-premise application.
An OPX long loop adapter connects to a single telephone line and can greatly extend the line’s loop length (the
Proctor Model 46222 adapter*, for example, can extend line length to 30,000 feet). You can also use OPX long
loop adapters to connect key systems (to share central office lines and system features).
*Proctor & Associates Company, Redmond, WA.
CAUTION
When you connect an adapter to an off-premise extension (OPX), you must ensure that the telephone line
routed to the OPX has primary protectors installed in series with the tip/ring pair to protect the user and
the equipment from transient voltage spikes that can travel through the cable. The telephone company
offers basic protection against this condition, but it is usually designed to protect only the central office
circuits. To help ensure that voltage surges do not damage the system, you should install and properly
ground gas discharge tubes or similar primary protection devices on the telephone line routed from the
adapter to the off-premise extension.
To install the OPX long loop adapter,
1. Follow manufacturer’s instructions for unpacking, inspecting, mounting, and wiring the adapter unit.
2. Plug a modular cable into the system jack on the adapter and connect the opposite end of the cable to the IST
jack on the ATI-D-1PT.
3. Plug a modular cord into the telephone jack on the adapter and connect the opposite end of the cord to the
OPX line.
4. Plug the adapter power cord into a standard 117 VAC, 3-wire electrical outlet.

IMI89–208 Installing And Programming The ATI-D-1PT

Programming For Analog Terminal Interface Operation
The ATI-D-1PT allows you to connect IST equipment to a digital station port.
The IST provides basic intercom service and the ability to access outside lines. You can program the IST station
port for Prime Intercom, Prime Line, Prime Line Group, or Idle Line Preference. Default is for No Prime. You
can set the station port to receive outside line ringing and to match either the pulse or tone dialing used by the
IST.
Detailing The Prime Intercom Operating Condition
With key-system configured digital communications systems, a multiline telephone user can extend line access for
call origination to an IST station by employing the call transfer feature. To provide outside line ringing to a prime
intercom IST, program the ATI-D-1PT station port to have the ringing line preference feature and then enable
ringing for all lines that you want to ring at the IST.
With hybrid configured digital communications systems, you can make outside lines available to the IST for call
origination by programming the IST for line group access. With line group access, the IST user can access an
outside line by dialing the group access code over the intercom line. The digital communications system then
selects one of the grouped lines for IST use.
Prime Line Automatic Or Idle Line Preference
You can program an outside line as a prime line at the station port through which the IST is being interfaced, or
you can program that station port for idle line preference and then assign several lines to the station port.
With either prime line automatic or idle line preference, the IST has outside line dial tone for call origination
when its user lifts its handset. You can enable outside line ringing at the IST station port that you have the idle
line preference programmed for either prime line automatic or idle line preference. Alternately, you can enable
the ringing line preference feature for the IST station port.
The intercom line is still available to an IST even though you have provided outside line access. After going
off-hook, the IST user obtains intercom dial tone by performing a hookflash (press and release the hookswitch) or
by pressing the TAP button if one is available. Hookflash either drops the outside line (if the user dialed no digits
after lifting the handset) or (if the user dialed some digits) places the line on hold and provides intercom dial tone.
Distinctive Ringing
Intercom calls that ring at equipment connected through an ATI-D-1PT have a different cadence than outside
calls. You can disable this distinctive ringing feature to make the intercom ring cadence identical to outside calls.
Through Dialing
You can program the station port through which the IST is being interfaced for through-dialing or you can disable
the feature. The system automatically enables the feature when you connect an ATI-D-1PT to the station port.
Through dialing enabled is necessary if the connected IST is a dual-tone multifrequency (DTMF) tone dial device
that requires that its generated dialing tones pass through the ATI-D-1PT, the common equipment, and onto a tone
dial compatible telephone line.
If the IST is a rotary telephone, you must disable the through dialing feature.
