E. GMX-416/832 DSS/BLF UNllT 
4.54 There can be a maximum of 50 Direct Station 
Selection/Busy Lamp Field @SS/BLF) Units installed 
on the GMX-416/832 System, including any of the fol- 
lowing: 
0 Inter-Tel/DVK DSS/BLF Units -single or tandem 
0 GMX DSS/BLF Units - single only 
0 GX DSS/BLF Units - single or tandem 
NOTE: For more information on the GMX and GX sta- 
tion instruments, refer to appendixes Aand B in the back 
of the manual. 
4.55 A DSS/BLF Unit consists of either a single unit 
or two units connected together to form a tandem unit. 
Each single unit provides one-key access to 6Onumbers, 
while tandem units provide access to 120 numbers. The 
numbers can be station extension numbers, hunt group 
pilot numbers, system feature codes, or system speed- 
dial numbers. 
4.56 The 50 single/tandem units can be distributed 
among several keysets or, if desired, they can be as- 
signed to one keyset. (Refer to page 3-136 for DSS/BLF 
Unit installation instructions.) 
457 DSS/BLF Units are programmed to be used with 
specific keysets, but are not physically attached to the 
keysets. Each unit requires a KSC-D circuit that is sepa- 
rate from the keyset’s circuit. If 50 station circuits are 
used for DSS/BLF Units, 50 fewer keysets and/or Atten- 
dant Computer Consoles can be installed. Up to four 
units can be installed on a single Keyset Card. 
4.58 For an illustration of the DSS/BLF Unit (and 
other Inter-Tel/DVK station instruments), refer to the 
drawings beginning on page 2-41. DSS/BLF Unit 
dimensions are: 
Height 3.8 in. (9.7 cm.) 
Width 7.0 in. (17.8 cm.) 
Length 9.5 in. (24.1 cm.) 
Weight 2.5 lb. (1.1 kg.) 
459 As stated earlier, each single DSS/BLF Unit pro- 
vides one-key access to up to 60 numbers. These num- 
bers can be station extension numbers, hunt group pilot 
numbers, or system feature codes, or system speed-dial 
numbers. The layout of the keys and the numbers they 
access are assigned using one of up to eight key maps (12 in expanded systems) in -database programming. 
The intercom number/key assignments are programmed 
in two lists, DSS 1 and DSS 2. Single DSS/BLF Units 
can be assigned with either list. Tandem Inter-Tel/DVK 
units are assigned with the DSS 1 list, then an internal 
strap is set to identify the key arrangement each individ- 
ual unit will use. 
4.60 Together, the lamps in the keys create a busy 
lamp field that indicates the status of each station or hunt 
group assigned to the keys. The LED indicator in the key 
is solidly lit when the associated station is busy, flashes 
slowly when the station is in do-not-disturb, flashes fast 
when the station has a call ringing in, or flutters continu- 
ously if the station is causing a STATION OFF-HOOK 
system alarm. If assigned to a hunt group, the LED indi- 
cator is solidly lit when all stations in the hunt group are 
unavailable (busy, forwarded, in do-not-disturb, or re- 
moved from the hunt group) and it flashes fast when a 
call is camped on to a hunt group. 
F. ATTENDANT COMPUTER CONSOLES 
4.61 
The Attendant Computer Console is an IBM- 
compatible personal computer that is connected to an 
available KSC or KSC-D circuit (they cannot be con- 
nected to DKSC circuits). The computer contains a pro- 
prietary circuit card and special software. It is primarily 
designed for use by attendants of larger 4161832 Sys- 
tems 
-those systems with so many station users that it 
would make using DSS/BLF Units somewhat awkward. 
However, due to its enhanced functionality, including 
electronic text messaging and directory dialing, the At- 
tendant Computer Console is also an attractive option 
for smaller 4161832 Systems as well. 
4.62 Attendant Computer Console design features in- 
clude: 
IBM XT-, /if-, or 386-compatible processing unit 
CGA, EGA, or VGA monitor and Monitor Interface 
Card 
122-key custom keyboard 
Headset operation 
Specially designed circuit card and interface soft- 
ware

Computer Console, along with detailed installation and 
programming instructions, refer to the manual included 
with the console.

4.69 Single-line set users access some station features 
simply by lifting the handset and pressing a feature key 
(or entering a feature code). Other features are accessed 
using a combination of a hookflash @LASH key) and a 
feature key or code. Refer to the FEATURES section of 
this manual for details. 
4.70 When single-line sets are connected to Single- 
Line Cards (SLCs), they must be equipped with AC 
ringers (ESLSs and SLIs have internal jumper straps 
that can be moved to set the ringer for AC or UC). When 
connected to Inward Dialing Cards (IDCs), single-line 
sets may have AC ringers by setting the IDC circuit for 
AC ringing, or they may have DC ringers by setting the 
circuit for DC ringing. (Refer to page 3-138 for single- 
line set installation instructions.) 
NOTE: IDCs do not support message waiting applica- 
tions. If single-line sets with message waiting lamps are 
installed on DC’s, the lamps will not function.

H. OFF-PREMISES EXTENSIONS (OPXs) 
4.71 An 
OPX is an AC ringer-equipped ESLS, SLI, or 
single-line DTMFset that is placed in a remote location 
and connected to the system through a telephone com- 
pany OPX circuit or a customer-provided circuit. 
4.72 Off-premises stations are connected to Inward 
Dialing Cards (up to eight circuits on a card) or to Tl 
Cards (up to 24 circuits on a card). If necessary, the re- 
ceive gain and/or the transmit gain for each circuit can 
be adjusted in database programming (see page 5-30for 
details). 
NOTE: If connecting OPXs, Inward Dialing Cards or 
Tl Cards must be used. FCC regulations prohibit con- 
necting OPXs to Single-Line Cards. 
4.73 The OPX circuits provided by the telephone 
company are identified with Facility Interface Codes 
(FE): Class A, OL13A; Class B, OL13B; or Class C, 
OL13C. The service order code is 9.OF (fully protected 
private circuit). Ifthe impedance does not exceed a loop 
measurement of 800 ohms (loop of 15,600 feet using 
24AWG wire), a customer-provided circuit between the 
remote location and the system may be used. 
4.74 The 800&m loop limitation is usually suitable 
for accessing on-premises stations from off-premises 
stations. However, for applications where one off-pre- 
mises station will be calling another through the station 
card, the impedance between the two off-premises sta- 
tions (both circuits added together) must be less than 
800 ohms (loop measurement). In this situation, a Class 
A or B FIC circuit is preferable. 
4.75 When an IDC circuit is designated for OPX use in 
database programming (see page 5-171), its voice vol- 
ume levels are increased approximately 3dB over nor- 
mal single-line set voice volume levels. This is an 
attempt to compensate for any loss in the external OPX 
circuit. However, in certain off-premises applications, 
the voice volume levels may still be unacceptable. This 
degradation in voice volume is due to the natural voice 
frequency range limitations of the telephone company 
or customer-provided circuit. To increase the frequency 
range, installation of a two-wire, negative impedance 
repeater unit is recommended. Such units typically pro- 
vide from O-15 decibels of voice volume gain and allow 
regulation of the gain in each direction when simulta- neous voice transmission occurs. The switching sensi- 
tivity on the unit should also be adjustable. 
4.76 The repeater unit is installed at the MDFbetween 
the station block and the cabling to the off-premises sta- 
tion. (Refer to page 3-31 for OPX installation instruc- 
tions.) When ordering a repeater unit, consult with the 
supplier for ordering the proper mounting shelf and 
power supply for the unit. Additional information on op 
erating and adjusting the repeater unit is generally in- 
cluded with the product. 
I. PLAYBACK DEVICES 
4.77 A playback device is an answering machine that 
answers the call, plays a message, and then disconnects 
from the call. Playback devices are installed like single- 
line sets, using three-pair twisted cable and sixconduc- 
tor modular jacks (or, if desired, one-pair twisted cable 
and four-conductor modular jacks). The device must be 
capable of the following functions: detect ringing, pro- 
vide ring trip, and automatically disconnect when the 
announcement is completed. 
4.78 Because most playback devices respond to 
AC 
ring signals, they are attached to SLC circuits or IDC 
circuits that are set for 
AC ringing. If the playback 
device responds to DC ring signals, an Inward Dialing 
Card circuit that is set for DC ringing must be used. (Re- 
fer to page 3-138 for playback device installation in- 
structions.) 
NOTE: For optimal performance, it is recommended 
automated attendant playback devices be installed on 
IDC circuits rather than SLC circuits. 
4.79 Hunt groups can have two special stations that 
help process calls: announcement stations and overflow 
stations. (See FEATURES, page 4-17.) These stations 
can be equipped with station instruments or playback 
devices. Automated attendant stations can also be 
equipped with playback devices. 
4.80 The playback device is programmed as a regular 
single-line station and is assigned an extension number. 
If the device is sensitive to camp-on tones and discon- 
nects calls, the programmer can disallow the camp-on 
tone for that station circuit (refer to PROGRAhMING, 
page 5-30).

EQUIPMENT 
A. PROGRAMMIN GKEYBOARD 
5.1 The 
programming keyboard must be an IBM AT- 
compatible keyboard equipped with a standard mule 
5-pin DIN connector (an XT-compatible keyboard can- 
not be used, unless it is equipped with an XT/m selector 
switch). The keyboard is connected to the peripheral 
connector panel on the back of the equipment cabinet, 
which is in turn connected to the PC Motherboard in the 
computer complex. 
B. PROGRAMMIN G MONITOR 
5.2 The programming monitor can be any standard 
monochrome monitor equipped with a 
male 9-pin sub- 
miniature “D” connector. The monitor is connected to 
the peripheral connector panel on the back of the equip 
ment cabinet, which is in turn connected to the mono- 
chrome Monitor Card in the computer complex. 
C. UTILITYSHELF 
5.3 An optional utility shelf that attaches to the out- 
side of the main equipment cabinet is available. For con- 
venience, items such as the programming monitor and 
keyboard can be placed on the shelf. The shelf is easily 
installed on either the left or right side of the cabinet by 
sliding it into place over the existing pins. (Refer to RE- 
PLACEMENT PARTS for the part number.) 
D. SMDR/SMDA OUTPUT DEVICE 
REQUIREMENTS 
5.4 The optional output devices for the Station Mes- 
sage Detail Recording (SMDR) and Station Message 
Detail Accounting (SMDA) features must have the 
characteristics described in the following paragraphs. 
The output devices are connected to the peripheral con- 
nector panel on the back of the equipment cabinet, 
which in turn is connected to the Pro68/Pro68E Card in 
the computer complex. 
5.5 If the output device will be connected to the SERI- 
AL, 1 port on the 416/832 System, one end of the cable 
between the two must have an RS232Gcompatible, 
female 9-pin subminiature “D” connector. The other end 
of the cable must be compatible with the output device.

5.9 When the system is in the default configuration, 
the 416/832 output device ports (SERIAL 1 and SERI- 
AL, 2) are enabled for “software” handshaking. Most 
output devices are designed for software handshaking, 
which is the use of “X-ON” and “X-OFF” characters to 
indicate readiness to send or receive data. Refer to the 
device’s operating manual to determine if it uses X-ON/ 
X-OFF characters. 
5.10 If the device does not support X-ON/X-OFF 
characters, hardware handshaking may be enabled (see 
PROGRAMMING, page 5-170). When enabled for 
hardware handshaking, signals are sent over the connec- 
tor pins to indicate readiness to send or receive data. The 
416/832 DB9 port (SERIAL 1) will send a logic true 
(>+5V) on pin 4 (Data Terminal Ready) and pin 7 (Re- 
quest To Send) when it is ready to receive data. In addi- 
tion, the 416/832 DB9 port will monitor pin 6 (Data Set 
Ready), pin 8 (Clear To Send), or both (depending on 
how the 416/832 System is programmed) and will only 
send data if it receives a logic true (>+5V) over the pro- 
grammed pin(s). Ifthe 416/832 DB9 port receives a log- ic false (+5V) on pin 20 (Data Terminal Ready) and 
pin 4 (Request To Send) when it is ready to receive data. 
In addition, the 416/832 DB25 port will monitor pin 6 
(Data Set Ready), pin 5 (Clear To Send), or both (de- 
pending on how the 416/832 System is programmed) 
and will only send data if it receives a logic true (>+5V) 
over the programmed pin(s). If the 416/832 DB25 port 
receives a logic false (

E. SYSTEM BATTERY BACK-UP 
5.15 To provide back-up power in the event of an 
AC 
power failure or brownout condition, the 416/832 Sys- 
tem power supply(s) can have optional battery back-up 
using a customer-provided uninterruptable power sup 
ply (UPS) unit or standby power supply (SPS) unit. 
5.16 For the main equipment cabinet only, it is recom- 
mended that a power supply unit with the following 
characteristics be installed: 
Sine wave output 
Transfer time of less than 20 milliseconds 
Output rating of 1600 Watts (minimum needed for a 
fully populated, non-expanded system; for smaller 
system requirements, see paragraph 5.22) 
External or internal batteries 
Low voltage cutoff circuit of 105VAC (minimum) 
5.17 If an expansion cabinet is installed, it is recom- 
mended that a power supply unit with the following 
characteristics be installed: 
Sine wave output 
Transfer time of less than 20 milliseconds 
Output rating of 2760 Watts (minimum needed for a 
fully populated, expanded system; for smaller sys- 
tem requirements, see paragraph 5.22) 
External or internal batteries 
Low voltage cutoff circuit of 1OsvAC (minimum) 
NOTE: Even if the power supply unit has the specifica- 
tions listed above, it cannot be guaranteed that it will 
work properly with the 416/832 System. Contact Cus- 
tomer Support for a listing of approved UPS/SPS power 
supplies and installation instructions. 
5.18 Batteries connected inseries form a “string.“The 
voltage of the string is equal to the sum of the individual 
battery voltages. For example, five 6V batteries con- 
nected in series form a 30V battery pack. If desired, con- 
nect two strings in parallel to double the amp/hour 
rating, which results in longer discharge rates; the volt- 
age level remains the same as a single string. 
5.19 Batteries must be fully charged when installed. 
Charge each individually using a constant-voltage, cur- 
rent-limited charger with less than three percent ripple. 
The charge voltage per cell must be set according to the 
manufacturer’s specifications. Be careful not to damage 
the batteries by overcharging them. For example, new 
Globe brand batteries require 25 days of float voltage or 
25-30 discharge cycles to attain full capacity. Initial ca- 
pacity might only be 80 percent of rated capacity. 
5.20 All batteries should be of the same age and AH 
rating. Some manufacturers date batteries by stamping 
them with a date code. For example, Globe stamps their 
batteries with a code such as 410-B, where 4 = the last 
digit of year, 10 = the month, and B = the type of electro- 
lyte. If a battery in a string needs to be replaced, the age 
of the string will determine if a fresh battery can be add- 
ed. If the string is two to three years old, adding a fresh 
batterywillreducethelifeoftheentirestring.Thisisbe- 
cause a fresh battery will be overcharged, while the old- 
er batteries are undercharged. 
5.21 Batteries may give off explosive and/or corrosive 
gases. To reduce the effects of this gas, place the batter- 
ies (or battery compartment) in a well-ventilated room 
and coat the terminals with an anti-corrosive agent. 
Avoid storing batteries; they will selfdischarge and 
their capacity decreases with age. If you must store bat- 
teries, recharge them every six months. Recharge time 
may vary depending on the charger’s current limit and 
the battery’s state of charge.
