Comdial Dxp Plus Instructions Manual

							2.3 Connecting The Equipment
Connect the cabling to the ATI-D-1PT per the diagram shown on the next page
CAUTION
Be careful when connecting the wiring between the DXP Plus 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 mistakenly 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. A ground stud is provided on the ATI-D-1PT housing
for this purpose. Connect a #10 or #12, insulated, solid copper wire between this ground stud and a reliable
earth ground.
2.4 Verifying Proper 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.)
2.5 Installing OPX Long Loop Adapter For Off-Premise Service
As stated previously, 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). In addition, such units can be
used to interconnect 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 insure that the telephone line
routed to the OPX has primary protectors installed in series with the tip/ring pair to protect both 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 the central
office circuits and you cannot rely upon it to protect common equipment.  To help insure that external
over-voltage surges do not damage the system, technical experts recommend that you 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:
·Follow manufacturer’s instructions for unpacking, inspecting, mounting and wiring the adapter unit.
·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.

							·Plug a modular cord into the telephone jack on the adapter and connect the opposite end of the cord to the OPX
line.
·Plug the adapter power cord into a standard 117 VAC, 3-wire electrical outlet.

							3.0 Programming For Analog Terminal Interface Operation
The ATI-D-1PT provides the interfacing capability required to connect most industry standard telephone (IST)
equipment to a digital station port of the digital communications system.
The IST provides basic intercom service coupled with the ability to access outside lines. You can program the
station port (through which the IST is being interfaced via the ATI-D-1PT) for either prime intercom operation or
prime line automatic and idle line preference operation. Default is for prime intercom. Under either operating
condition, you can program the station port to receive outside line ringing and to match either the rotary or DTMF
dialing employed by the IST.
3.1 Detailing The Prime Intercom Operating Condition
With key-system configured digital communications systems, a system 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.
3.2 Detailing The Prime Line Automatic Or Idle Line
Preference Operating Condition
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
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 used dialed no digits
after lifting the handset) or (if the user dialed some digits) places the line on hold and provides intercom dial tone.
3.3 Detailing The Distinctive Ringing Condition
Intercom calls that ring at equipment connected through an ATI-D-1PT have a different cadence than outside calls
have. If desired, you can disable this distinctive ringing feature to make the intercom ring cadence the same as that
for outside calls.
3.4 Detailing The Through Dialing Condition
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.
