Comdial Enterprise Interface For Telephony Services
1.0 Introducing This Option
This option is a driver for the DXP and DXPPlusdigital communications systems. When installed on a
Novell* local area network (LAN) telephony server, the driver software integrates the digital
communications system with the computer network. The other software required for the system to operate
is Novell NetWare* and Novell Telephony Services* installed on the server. Also, one of the
commercially-available telephony applications must be installed on each client. A client is an individual
personal computer (PC) connected to the network.
This option makes many of the digital communications system features available to telephony application
programs running on client PCs. The illustration below shows a simple network configured for three
clients using this technology usually referred to as Computer Telephone Integration (CTI).

							2.2 Connecting The Server Directly To The DXP Plus System
You must install a communications card in the DXP Plus to provide a serial port that you can use as the
server interface. Since this is a detailed installation, it is important that you refer to IMI89–190, Installing
The DXOPT–COM Communications Card In The DXP Plus Digital Communications System, for
complete installation details. This communications card that supplies the serial data port may be located
on the services board or the auxiliary board installed in the main DXP Plus equipment cabinet or the card
may be located on the interface board in either the upper or lower expansion cabinets. Regardless of the
location, the connector pin-out is the same and the data baud rate is 9600 baud.
Once you have provided a serial data port for the server to use, install the following kit-supplied items:
software key, modular to 25-pin EIA adapter, and 6-conductor line cord for connecting the server’s
RS-232 port to the DXP Plus system.
1. Install the software key supplied in the kit on the 25-pin serial port on the rear of the server. If you are
using the 9-pin serial port, you must first install a 9-to 25-pin adapter (see the following note).
NOTE: When using the 9-pin serial port, locate a 9-to 25-pin adapter. These are available at most
computer stores. Make sure pins 4 and 6 on the DB-9 end of the adapter are connected to pins 20
and 6 respectively on the DB-25 end.
2. Plug the modular to 25-pin adapter supplied in the kit onto the connector on the software key.
3. Plug one end of the kit-supplied line cord into the modular connector on the adapter you installed in
step 2. Plug the other end of the line cord into the DXP Plus’ serial port that you made available with

							2.3 Connecting The Server Through House Wiring
Before using house wiring to connect the server to the system, make a direct connection and test the
equipment for proper operation without the added complications sometimes caused by house wiring.
The recommended maximum hard-wired distance for server to system interconnection using 24-gauge
wire is 500 feet for a 9600-baud transmission rate.
1. Install a customer-supplied 9-pin to 25-pin adapter (if applicable), the kit-supplied software key, and
the kit-supplied 25-pin to modular adapter on the rear of the server as described in sections 2.1 and
2.2.
2. Plug one end of the kit-supplied line cord into the modular connector on the 25-pin to modular
adapter you installed in step 1. Plug the other end of the line cord into the modular jack on the
server-end of the house wiring.
3. Using a customer-supplied, standard 6-conductor line cord, plug one end of the line cord into the jack
on the system-end of the house wiring. Plug the other end of the line cord into the appropriate system
serial data port
4. If a connection problem occurs, refer to section 2.4 for a signal interconnect diagram. Using this
diagram and an ohmmeter, you can trace through all of the circuit paths between the server and
system to verify that you made the correct connections.
CAUTION
A standard 6-conductor line cord introduces a signal roll-over from one end to the other. You
must maintain this signal roll-over when you install the house wiring. The illustration below
shows this roll-over in place in the wiring from one modular jack to the other. The additional
roll-overs introduced by the connecting line cords negate one another and are not a factor for
consideration.
