2.7ConnectingA DSWBLF Console
IMZ66-068
You can install a DSS/BLF Console at any port in the system as a companion to a station installed at the data-p~red
port (e.g.; ports 20 and 21). When installing a DSS/BLF, make sure that you consider all of the following:l
The maximum number of consoles that you may install on a system is equal to one-half of the total station
capacity of the system.l
The installed distance limit between the common equipment and the console is the same as allowed for a
telephone.
Connect all four wires (voice and data pairs) of the console cable to the station connector block,l
When you install a console, you must also program the port as a console port (see chapter 3, section 3.7.30).l
The first 32 buttons of an installed console are defaulted as blank autodial buttons available for user
programming.On installed 
78button consoles, the remaining 32 buttons are fixed as DSS buttons for station
ports beginning with port 42 at button C42.l
The voice pair connections of the station port at which a console is installed can be used simultaneously to
enable a station PA port function employing an external PA system-2.8.5.If 
YOU do this programming, the
station port 
mzut be dej%zed as a External Paging Interface (see chapter 3, section 3.7.18)

2.8 Installing System Options
The ExecuTech 2000 system offers several options that are not part of the regular installation of the common
equipment. You may consider an expansion port or a power failure station connection, for example, as a
non-mandatory installation option. Section 2.8 covers all of these non-mandatory options. The following is a list of
those features:l
Key System / Hybrid Systeml
Power Failure Stationl Auxiliary Interface
lCommon Audible and Auxiliary Station Interfacel
External Paging Interface-Station PA Portl
External Paging Interface-Line Portl Data Device
l Music Interface
l
Cassette Tape Recorder Interface
2.8.1Connecting a Key System or Hybrid System
In the past, the Federal Communications Commission (FCC) required that telephone system manufacturers provide a
hardware strap that installers could move to distinguish between hybrid and key system operation. Recent rulings by
the FCC have eliminated the need for the hardware strap.Beginning with software release 11A of the ExecuTech
2000, the telephone system automatically assumes the hybrid mode whenever a programmer assigns lines to line
groups, and the system no longer includes a hardware strap that the installer must move. The hybrid system may
have a higher monthly tariff from the telephone company, so the FCC requires that the installer report the equipment
category designation number 
(KF for key system MF for hybrid system) to the telephone company at the time of
installation.

2.8.2Connecting A Power Failure Station
The system provides a tip and ring pair connected to line 1 as an emergency, power failure circuit. This circuit is
active during a commercial AC power failure. You can connect an industry standard, single-line telephone, such as
a Comdial model 
250Qxx, to a power failure pair and use that station to provide communications capability until the
AC power to the system is restored.
The power failure is detailed in Figure 2.6, below.l

2.8.3Connecting An Auxiliary Interface
Instal!ktion
You can connect a non-key system telephone device or a data device, such as a modem or fax machine, onto a line
ahead of the common equipment. The system can detect an off-hook condition in the connected device and turn on
the line status light at the key system telephones to indicate that the line is busy.In other words, all stations would
know that the fax or modem line is in use and would not pick up that line and risk damaging the fax or modem
transmission. Table 2.1, page 2-8, and Figure 2.7, below, detail the auxiliary interface connections.
NOTE: When the auxiliary interface feature is being employed, the line to line port reassignment, as discussed in
section 2.5.2, can only be used to reassign line 2 to line port 4 and line 4 to line port 2l
Connection is across tip and ring of lines 2 (aux 1) and 4 (aux 2). Use the auxiliary interface connections
provided at terminals 1 and 6 of common equipment Line Jacks 1 and 2.

							znstallationZMZ6G0682.8.4 Connectin A Common Audible
And Auxi
19uuy Station Interface
You can connect an external audible ringer, such as a loud bell or flashing light, that will operate when the system
receives an outside call.
The contact points for this operation are dry, meaning that the external ringer or light must
have its own power supply.
There are two different ways to install an external ring indicator device.The two sets of relay closures with dry
contact points are as follows:l
One set (common audible) provides a dry-contact closure whenever any of the outside lines, connected to the
common equipment, ring.l
The other set (station 17 audible) provides a dry-contact closure whenever station I7 rings. You must program
the lines that you want to ring on station 17 (station 17 defaults to all lines, and you must remove the lines that
you do not want to ring the external ringer).
These contact closures track the ringing pattern in both cases.The contacts are closed during the ringing period and
are open during the silent period.
Do not exceed a I amp at 24 volts (0.5 amp at 48 volts) load on these control terminals.If the load requirements
exceed this limit, connect the load through an external slave relay.Do not connect these control terminals directly
to the 
117vac line.
Refer to the section 2.8.5 for a discussion on using these terminals in an alternate paging function.
Contact closure connections are located as follows.l
Hine, 12-station and lo-line and 32-station base unit: Screw terminals l-2 and 3-4 on barrier-type terminal
strip.l
8-line, 20-station base unit: Clip terminals 4748 and 49-50 on connector block J-2

							znst4luutionZMZ66-0682.8.5Connecting An External Paging
InteTface-Station PA Port
You can program any station port, except for station 10, as a PA port.The station port that you choose can then
couple a station voice path to an external paging amplifier.If you configure the PA port so that music plays over the
PA until someone voices over, you must use either station 17 or common audible, station 15. No other station
connection will allow the voice-over. Refer to Chapter 3, section 3.7.18 for more information on programming a PA
port.Before you configure a port as a PA port, consider the following:l
The audio input connection must be isolated with a 600 ohm to 600 ohm audio matching transformer.
Terminate the audio input of the paging amplifier with a 620 ohm (nominal value) resistor.l
If you program station port 17 as a PA port, the Auxiliary Station Interface (station 17 audible) contact points
are automatically reconfigured as PA enable terminals.The contact closure now occurs when a user dials PA
station 17. The normal auxiliary station interface function, as discussed in section 2.8.3, is disabled as long as
station 17 is a PA station.
Connect the audio input of an external paging amplifier to the audio pair of the desired station port (refer to Tables
2-2 through 24 for station connection details). If the paging amplifier needs to be enabled in order to function,
connect the audio input to station port 17 and the enabling leads according to the following discussion and as
illustrated below.l
6&e, 1Zstation and 16-line, 32-station base unit: Screw terminals 1 - 2 on barrier-type terminal strip..
8-line, 20-station base unit: Clip terminals 47 - 48 on connector block J-2.

2.8.6Connecting An External PagingInterface-Line Port
You can program a line port to be an Auxiliary port.As an Auxiliary port, the line port can be used to couple a
station voice path to an external paging device.Any station with that line appearance can use the PA port simply by
selecting the line. Users can dial 
DTMP tones or dial pulses through the Auxiliary port. If users need to be able to
voice-over PA music, you must use station 17 or common audible, station 15, as the PA port. For more information,
see Chapter 3, section 3.6.8.When configuring a line port as a PA port, consider the following:
,:::.:l
The audio input of an external paging amplifier can be connected to the tip and ring leads of the Auxiliary port
as shown below.l
A DTMF tone select, zone-paging amplifier can be employed if desired. If you install this type of amplifier,
users must dial the zone-select code after pressing the Auxiliary port line select key.

							ZMZ66-0682.8.7Connecting A Data Device
The system provides two RS232 Data Ports for use in connecting a data printer, video display terminal (VDT), or
modem for remote programming.
Before you connect anything to a data port, consider all of the following:l
When you use a video display terminal (VDT) or a personal computer to perform class of service programming,
connect it to RS232 Data Port A.l
When you use a serial data printer for SMDR, MDA, and COS printout, COMeCt it to the RS232 Data Port B.l
The distance between the data device and the common equipment can be up to 500 feet in a quiet electrical
environment. Shielded cable may be required at some sites for long runs. For longer distances, a limited
distance modem must be used to relay the data communications between the common equipment and the data
device.
2.8.7.1Wiring The Data Device
When preparing a cable for connection to a data device, refer to the manufacturer’s manual for the equipment being
interfaced, and make the following wiring connections:l
Wire the common equipment RD (data from device to common equipment) connection to the device TD
(transmit data) connection.l
Wire the common equipment TD (data to device from common equipment) connection to the device RD
(receive data) connection.l
Wire the common equipment SG (signal ground) connection to the device SG (signal ground) connection.l
If required for proper operation, wire the common equipment CTS (clear-to-send status from device to common
equipment) connection to the device RTS (request-to-send) connection.NOTE: The common equipment requires a positive voltage, with respect to signal 
ground in order to send data.
2.8.7.2Conjiguting The Data Device
The default data format is as follows.
Configure the data device to match this data format for initial operation..
7-bit data with 2 stop bits and no parityl
Baud rate of 300 baud
