							2.4 Checking Signal Paths
To verify correct signal paths between the server and the system, use the following illustration to locate
the signal paths and check them using an ohmmeter.
Be sure that the RD, TD, RTS, and CTS signals from the server connect to the appropriate signals at the
system serial data port as detailed in this table.

1. About...
2. Active Session Information
3. DXP Link Administration
4. Select Active Serial Port
3.1.1 Using The About... Menu To Access Software Version Information
Selecting the About... menu option provides current software version information for both Telephony
Services and the DXP system.
NOTES: 1. A Telephony Services Link must be active for the DXP Firmware Version to be shown;
otherwise, the version will be shown as UNKNOWN.
2. At least one active session must exist before the Telephony Services driver version  can be shown;
otherwise, the version will be shown as UNKNOWN.
3.1.2 Using The Active Session Information Menu
Selecting the Active Session Information menu option provides the following options:
1. Display Active Sessions
2. Display Monitored Calls
3. Display Monitored Devices
3.1.2.1 Displaying Active Sessions

							3.1.3 Using The Link Administration Menu Options
Selecting the Link Administration menu option provides additional options as follows:
1. Clear Port Statistics
2. Close DXP Link
3. Edit Port Configuration
4. Open DXP Link
The first line of the option screen shows the active serial port (example, “Board:0 Port:0).
3.1.3.1 Clearing Port Statistics
Selecting this option resets all of the monitored items on the “Link Statistics Screen” such as busy hour,
busy minute, and packets received.
3.1.3.2 Closing A Link
Selecting the close link option terminates the Telephony Services link established for the active serial
port. Any other active links are unaffected.
3.1.3.3 Editing Port Configuration
Selecting this option allows you to modify the following parameters:

NOTE: The new values become effective the next time you load the DXP driver (see section 2.2,
“Installing The Software”).
3.1.3.4 Opening A Link
Selecting the open link option establishes a link to the system using the active serial port. Any other
active links to other systems are unaffected. If the server is unable to establish a link, the screen shows a
Link Failed message. If this occurs, verify cable connections and try again. If you are still unable to
establish a link, please refer to the “Trouble shooting” section in this document for other possible causes.
See also section 3.2.

							4.0 Trouble shooting The Interface Option
Problem Possible Cause
Unable to load Comdial NLM 1. Telephony Service’s software not installed correctly.
2. Telephony Service’s network loadable module (NLM) not loaded.
The COMDIAL.NCF file on the supplied diskette shows the loading
order of all required NLM’s
Cannot establish DXP link 1. Line cord between server and DXP not connected or loose
connection in house wiring, if used.
2. Software key incorrect or not installed.
3. DB-9 to DB-25 adapter does not have pins 4 and 6 from
the DB-9 side. These pins are needed for establishing communications
(handshaking) between the server and the DXP system.
4. CTS/RTS flow control not selected on the DXP system port.
5. Line cord connected to the wrong port on the server.
6. Incorrect baud rate selected on the DXP system.
7. Incorrect active port selected in driver administration.
Access denied to Telephony Services Software key not compatible with size of Telephony Services
installation. For example, Telephony Services installation and license
is for 100 users while the software key is for a system driver compatible
with a 50-user installation.

							Installing And Programming The Analog Terminal
Interface On The Digital Communications System
1.0 Introducing The Analog Terminal Interface
This publication describes the features, applications, installation, and specifications of the Comdial Analog
Telephone Interface (ATI-D-1PT). The ATI-D-1PT is a multipurpose,on-premiseaccessory for the digital
communications system.  It provides the following features:
·INDUSTRY-STANDARD TELEPHONE (IST) INTERFACE -This feature adapts most industry-standard
telephone (IST) devices to the digital station board of the DXP system. The ATI-D-1PT 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
telephone company-supplied line unless an acceptable OPX long loop adapter is installed. Refer the
installation section for adapter installation instructions.
The ATI-D-1PT is housed in a self-contained wall mountable metal enclosure. The ATI-D-1PT receives its power
from the digital communications system through the station port connection. the ATI-D-1PT contains an internal
ringing generator to generate a ringing signal for an IST and high quality, low-loss, balanced, telephone
transmission circuitry that supports one IST input.
Connection between the ATI-D-1PT and a common equipment digital station port requires one single-pair cable
(two-wire). Connection between the external analog IST equipment and the ATI-D-1PT requires Another single
pair of wires. The ATI-D-1PT provides modular connectors to allow quick connections.
The ATI-D-1PT circuit will drive a load with a maximum ringer equivalence number (REN) of 2.0 thus allowing
more than one IST connection at each interface input. Check the REN number of the connected IST equipment so
as not to exceed the capacity of the ATI-D-1PT. Improper operation may result if the REN maximum of the
ATI-D-1PT is exceeded.
The ATI-D-1PT supports a wide variety of IST equipment such as 500 and 2500-type telephones, cordless
telephones, answering machines, FAX machines, and data modems.

							2.0 Installing The Analog Terminal Interface
2.1 Detailing The Mounting Considerations
1. The ATI-D-1PT can be attached to any sturdy, flat surface.
2. The distance between the ATI-D-1PT and the common equipment must be 25 feet or less.
3. The mounting location must be secure and dry and have adequate ventilation. The temperature range of the
location must be within 32-122° F (0-50° C).
4. If the mounting surface is damp or if it is concrete or masonry material, a backboard must be attached to it
before mounting the ATI-D. Suitable mounting backboards are available commercially or can be constructed
out of 1/2-inch plywood cut to size.
5 Tools and hardware required for mounting the ATI-D include:
·Fasteners - wood screws (1/4 x 1-inch round head), toggle bolts, or wall anchors.
·Screwdriver - to match fasteners.
·Electric drill - if prepared holes are required.
·Connecting tool - for fastening wires to a type-66 connector block.
·Crimping tool - for 623-type modular plugs.
2.2 Mounting The Cabinet
1. Unpack and carefully inspect the ATI-D-1PT for shipping damage. Notify the shipper immediately of any
damage found. Verify that the package contains all parts and accessories needed for proper installation and
operation.
2. If a backboard is required at the mounting location, attach it securely to provide a stable mounting surface.
3. Use the base of the ATI-D-1PT as a template or measure for mounting hole locations per the dimension
details shown in illustration.
4. Drill holes of a proper size to accommodate the hardware being used into the mounting surface. If
necessary, prepare these holes with inserts, anchors or other attachment devices as dictated by the type
of mounting surface.
5. Insert the two top screws into the mounting surface and tighten them to within approximately 1/8-inch
of the surface.
6. Hang the ATI-D-1PT on the top screws using the mounting holes located on the rear of the cabinet.
Note that these holes are elongated with an enlargement at one end. This feature allows the cabinet to
snap down on the screws to secure the mounting when the cabinet is hung on them.
7. Insert a third screw through the mounting tab located on the lower edge of the cabinet and into the
mounting surface; tighten it into place.
