Comdial Dsu II Digital Telephone System Instructions Manual

							2.18.5 Supporting The Tracker Paging System
The optional Tracker paging system allows you to send alpha/numeric or numeric-only messages
to the Tracker Pagers assigned to a station extension number. The type of message that the
system delivers is dependent on the Tracker Pager model being used. Tracker’s paging option
requires only one connection to the digital telephone system; however, you will need to take
several programming steps to make it operational.
·If you use station 10 programming to configure the system, install the Tracker base station
to the common equipment cabinet’s COM1 serial data port. Then, after you have completed
the installation, take the programming action detailed in Chapter 3, Section 3.17.
·If you use a video display terminal (VDT) to configure the system, you must connect it to
the COM1 serial data port andyou must take programming action to enable the Tracker
Pager option and enable Tracker Pagers at stations before you actually install the
Tracker Pager system.(This is necessary since the Tracker Pager system also uses the
COM1 serial data port and there would be no way to program with a VDT if the Tracker
Pager system was already installed.)
1. When you finish programming, press CONTROL C for the main menu, and log out from the
programming mode.
2. Disconnect the VDT from COM 1. As soon as you do this, the system begins polling COM1
every two seconds and waiting for a response from a Tracker base station.
3. Connect the Tracker Pager system to COM1. As soon as you connect the Tracker base
station to COM1, the DSU II system recognizes the Tracker base station’s presence and
makes Tracker Pager features available to the system users.
NOTE: While the Tracker base station remains connected, the system continues to poll the
port every 10 seconds to verify its presence. This means that if you disconnect the
Tracker base station to reconnect the VDT, you may have to wait as long as 10
seconds for the system to notice that you have replaced the Tracker base station with
a VDT.

							2.18.6 Supporting DVA Operation
Digital voice announcing uses a hardware peripheral device (product code DVA01) connected to
a digital station port to play pre-recorded announcements and messages during an in-progress
call. The DVA stores the pre-recorded messages in its memory for recall when needed.
The DVA derives its operating power from the common equipment cabinet’s digital station port;
however, the DVA also provides internal connections for a battery. When installed, this battery
powers memory that holds the stored messages should someone disconnect the DVA for some
reason. Should you need to replace this battery, use one that meets the following specifications:
·Output-8.4 volts, 100 mAh
·Type-Sealed, rechargeable Ni-Cad battery
·Model-Varta V7/8R or equivalent (Varta Batteries Inc., 300 Executive Blvd., Elmsford NY
10523)
To install the DVA device,
1. Position the DVA01 in a convenient location.
2. Connect the DVA01 to a digital station port using an RJ14C-configured standard two-wire
line cord.
3. If you need to input pre-recorded messages during programming, use a customer-supplied
audio cable terminated with 3.5mm (1/8 inch) phone plug on one end and and appropriate
tape recorder mating connector on the other end.
4. Refer to Chapter 4 for details, and program the system for DVA operation.

							2.18.7 Installing The Personal Computer Interface Unit
(Projected Availability of this feature is first quarter of 1997)
The Personal Computer Interface Unit (PCIU) is a device that you can connect between a digital
station port and its proprietary telephone. The PCIU allows telephone users to initiate telephone
and voice mail related functions from their personal computer (PC).
The PCIU includes Service Provider Interface (SPI) software on computer diskettes. When you
install this SPI software on a PC, the PC users can employ their Telephony Applications
Programming Interface (TAPI), third-party Microsoft* Windows applications programs to
control many useful telephone functions.
When you make the Visual Voice Processing (V.V.P.) Visual Call Manager (VCM) software
option available, the voice mail system can use the serial data path to the PCIU to send messages
to the telephone’s display and to the SPI on the PC.
*Microsoft is a registered trademark of Microsoft Corporation, Redmond, Washington
Making The PCIU Cable Connections
Four cable connections are required to the PCIU-station line cord, digital telephone line cord, PC
cable, and power cable.
1. Disconnect the line cord on the digital telephone from the digital station port connector and
plug it into the connector labeled PHONE on the PCIU.
2. Connect the supplied serial data cable between the PC’s serial data port (COM port) and the
PCIU’s serial port connector.
3. Plug one end of a standard line cord into the connector labeled LINE on the PCIU. Plug the
other end of the line cord into the digital station port connector.
4. Plug the transformer attached to one end of the power cable into a 115 VAC electrical wall
outlet. Connect the other end of the power cable into the PCIU connector labeled POWER.
The green LED on the PCIU will be on to indicate power is being supplied to the PCIU.
NOTE: PCIU power loss will create the same symptoms as the disconnection of the PCIU
from the digital telephone system. If this occurs, plug the digital telephone directly into a
digital station port connector.

							Making The PCIU Operational
To make the PCIU operational, you need only follow the instructions enclosed with the SPI
software, and load it on the user’s PC. There is no programming action required on the DSU II
digital telephone system to make the PCIU operational; however, it does require that the
software revision be at 2A or later. However, if you use the PCIU with the V.V.P. voice mail
system, you must program enable the Visual Voice Mail (VVM) option.

							2.18.8 Connecting The Versatile Voice
Processing Voice Mail System
The Versatile Voice Processing (VVP) voice mail system provides voice mail and automatic
attendant features to the DSU II digital telephone system. A Comdial proprietary voice board
and proprietary software package installed in a personal computer (PC) provides the VVP
feature. A separate publication, which is supplied with the VVP equipment, discusses its
installation, programming, and operating details. The information contained below discusses the
VVP connections to the DSU II.
The VVP requires industry-standard telephone (IST) station ports for its interface to the DSU II.
Each VVP voice port requires its own IST interface. To provide the necessary IST interfaces,
you must either install a JM008 expansion module (Section 2.14.2) or connect an ATI-D
(Section 2.18.2) to the DSU II common equipment cabinet. Remember, one JM008 expansion
module provides eight IST ports while each ATI-D provides two.
The VVP software uses both voice and signalling paths between the DSU II and the VVP voice
processing circuit board. By using an in-band signalling technique, the IST ports handle both of
these paths. The efficiency of in-band signalling is dependent upon the availability of idle paths,
and busy systems that rely on in-band signalling sometimes slow down. Busy systems work
more efficiently when the signalling path is provided through a serial data connection between
the VVP’s PC and the DSU II’s common equipment. This arrangement is termed serial
integration. You must provide serial integration if VVP includes the optional Visual Voice Mail
(VVM) feature or if you are using the PCIU (Section 2.18.7) to provide this feature to a single
system telephone.

							2.19 FCC Rules And Regulations
This electronic key system complies with Federal Communications Commission (FCC) Rules, Part 68. The FCC
registration label on the common equipment cabinet contains the FCC registration number, the ringer equivalence
number, the model number, and the serial number or production date of the system.
Notifying The Telephone Company
Unless a telephone operating company provides and installs the system, the telephone operating company which
provides the lines must be notified before a connection is made to them. Provide the telephone company with the
lines (telephone numbers) involved, the FCC registration number, the ringer equivalence number, the Facilities
Interface Code (FIC), the Universal Service Ordering Code (USOC), and the USOC jack required. The FCC
registration number and the ringer equivalence number is provided on the label attached to the common equipment.
The FIC and USOC information is provided in the equipment’s general specifications found in equipment system
manual. The user/installer is required to notify the telephone company when final disconnection of this equipment
from the telephone company line occurs.
Understanding Telephone Network Compatibility
When necessary, the telephone operating company provides information on the maximum number of telephones or
ringers that can be connected to one line, as well as any other applicable technical information. The telephone
operating company can temporarily discontinue service and make changes which could affect the operation of this
equipment.  They must, however, provide adequate notice, in writing, of any future equipment changes that would
make the system incompatible.
Understanding Installation Requirements
Connection of the electronic key system to the telephone lines must be through a universal service order code
(USOC) outlet jack supplied by the telephone operating company. If the installation site does not have the proper
outlet, ask the telephone company business office to install one. The correct outlet jack for this system is either a
type RJ21X or type RJ14C.
Understanding Party Line And Coin Line Limitations
Local telephone company regulations may not permit connections to party lines and coin lines by anyone except the
telephone operating company.
Troubleshooting The Service Problem
If a service problem occurs, first try to determine if the trouble is in the on-site system or in the telephone company
equipment.  Disconnect all equipment not owned by the telephone company.
If this corrects the problem, the faulty equipment must not be reconnected to the telephone line until the problem has
been corrected.  Any trouble that causes improper operation of the telephone network may require the telephone
company to discontinue service to the trouble site after they notify the user of the reason.
Authorizing Repairs
FCC regulations do not permit repair of customer owned equipment by anyone except the manufacturer, their
authorized agent, or others who might be authorized by the FCC. However, routine repairs can be made according to
the maintenance instructions in this publication, provided that all FCC restrictions are obeyed.
