NIGHT TRANSFER (OF RINGING) 
The day, or normal, ringing of incoming lines can be 
: transferred to a particular station or stations (chosen 
through class of service programming) for off-hour or 
special purpose answering. The night transfer mode 
can only be activated from station 10. Night transfer 
of ringing can be assigned to specific stations using 
system or administration programming. It is then 
turned on or off by using system or administration as 
well as attendant class of service programming. 
OFF-HOOK VOICE ANNOUNCE WITH 
HANDSFREE ANSWERBACK 
With the off-hook voice announce (OHVA) feature, an 
announcement can be made from one station to 
another station that is off-hook or busy on a call. To 
receive an OHVA announcement, the OHVA station 
can be equipped with either a telephone and adjunct 
feature module combination or with a telephone that 
has secure off-hook voice announce (SOHVA) 
capability built into it. The announcement is preceded 
by an alerting tone and delivered through the 
loudspeaker in the adjunct feature module or the 
SOHVA equipped telephone. The called party can 
reply in a handsfree manner to a OHVA an- 
nouncement without interrupting the active call. Reply 
in made through the OHVA microphone included in the 
adjunct feature module or in the integrated OHVA 
capability telephone. Stations that have the voice an- 
nounce blocking feature turned on cannot receive a 
OHVA announcement. System or administration 
programming is used to enable the OHVA feature at a 
station port. Also refer to the discussion titled: 
SECURE OFF-HOOK VOICE ANNOUNCE. 
OPX SUPPORT 
The system will support the operation of the optional 
off premises extension (OPX) unit. System or ad- 
ministration programming is used to program a station 
port for OPX operation. 
ORIGINATING DENIED 
The ability to originate calls on certain lines can be 
denied at individual stations through system program- 
ming. The originating denied feature is programmed 
on a per station/per line basis. Originating denied 
does not prevent a user from answering a ringing line, 
retrieving a held call or receiving a transferred call. 
Call origination on a line is denied at a particular sta- 
tion by the system or administration programming. 
PERSONALIZED RINGING TONE 
‘I This programmable feature enables stations to ring in 
a distinctive manner with one of four different tones. 
The ringing tones are combinations of four different fre- quencies and two different warble rates. Personal ring- 
ing tones can be assigned with system or administra- 
tion programming. 
PRIME LINE AUTOMATIC 
If a station is programmed for prime line automatic, the 
designated outside line or intercom line will be auto- 
matically selected when the handset is taken off hook. 
Prime line pick up may be pre-empted by preselecting 
another line before lifting the handset. If the prime line 
is ringing, it is automatically answered by lifting the 
handset. Assign a prime line to a station through sys- 
tem or administration programming. 
PRIVACY RELEASE 
A line can be made non-private at a particular station 
while remaining private at all other stations. This ar- 
rangement allows other stations with that line ap- 
pearance to join that particular station whenever it is 
on the privacy-released line. A line is specified as 
private or non-private at a particular station with sys- 
tem or administration programming. Also see the dis- 
cussions titled, ADD-ON CONFERENCE and 
AUTOMATIC PRIVACY. 
PROGRAMMABLE KEYS 
All multiline keysets are equipped with a minimum of 
twelve softkeys which can be programmed a line pick- 
up, auto dial, station speed dial, and DSS action. 
Refer to the discussions titled, AUTO DIAL, 
PROGRAMMABLE DSS, and STATION SPEED DIAL. 
System or administration programming is used to as- 
sign functions to softkeys. 
PULSE/TONE SWITCHABLE 
When rotary dial lines are installed, the user can 
switch from pulse (rotary dial signals) to tone (Dual 
Tone Multiple Frequency signals - DTMF). This fea- 
ture is useful for accessing special circuits requiring 
DTMF tones such as banking machines, etc. The sys- 
tem is programmed on a per line basis to allow this 
feature at all stations. The system or administration 
class of service programming enables this feature on 
a per line basis. 
RINGING LINE PREFERENCE 
The system can be programmed on a per station basis 
to provide ringing line preference on all lines 
programmed for ringing at a station. 
When ringing line preference is enabled at a station, 
taking the station off-hook automatically connects it to 
any outside line which happens to be ringing at the sta- 
tion. A line key will not have to be pressed. The ability 
of a particular station to answer a ringing line without 
2-7  
						

							IMI 66-064 Description Of Prgrammable Features 
line selection is enabled by the system or administra- 
tion class of service programming. 
SECURE OFF-HOOK VOICE ANNOUNCE 
With the secure off-hook voice announce (SOHVA) fea- 
ture, a secure announcement can be made from one 
station to another station that is off-hook or busy on a 
call. A station being operated in a handsfree mode 
cannot receive a SOHVA announcement. A station 
must be equipped with a telephone that includes 
SOHVA capability to receive an SOHVA message. 
With SOHVA, the announcement is delivered and 
responded to in a secure manner that prevents the dis- 
tant party from hearing either the announcement or 
the response. The announcement is preceded with a 
tone alert and delivered to the handset receiver of the 
telephone. The announcing caller receives a tone 
alert upon calling to alert them that they are making an 
SOHVA call. Response to the announcement is ef- 
fected by pressing and holding the MUTE key and 
speaking into the handset. Stations that have the 
voice announce blocking feature turned on cannot 
receive a SOHVA announcement. System or ad- 
ministration programming is used to enable the 
SOHVA feature at a station port. Also refer to the dis- 
cussion titled: OFF-HOOK VOICE ANNOUNCE WITH 
HANDSFREE ANSWERBACK. 
SQUARE/NON-SQUARE SYSTEM 
A system can be programmed to be square or non- 
square as desired. In a square system, a specific line 
is assigned to the same key on every station in the 
system. In a non-square system, any line can be as- 
signed to any available softkey on every station in the 
system. Also refer to the discussion titled, TENANT 
SERVICE. Key mapping for line appearance can be 
performed on each station using the system or ad- 
ministration class of service programming. 
STATION BY STATION PRIVACY 
Refer to the discussions titled, AUTOMATIC PRIVACY 
and PRIVACY RELEASE. 
SYSTEM SPEED DIAL 
Thirty, system-wide, speed dial numbers are provided. 
The system speed dial numbers can be up to fifteen 
digits in length, and can include numbers, #‘s, %‘s, 
pauses, and flash signals. System speed dial number 
programming can only be performed at station 10; 
however, once programmed, they can be used at 
every station in the system. System, administration, 
or attendant programming can be used to program sys- 
tem speed dial numbers. 
TAP (FLASH/RECALL) 
When host system custom calling features are avail- 
able via a “flash” signal, the system can be 
programmed so that the 
TAP key will generate a 
“flash” signal when it is pressed. When custom calling 
features are not available, the 
TAP key functions as a 
positive disconnect or dial tone recall key. These two 
features are mutually exclusive. The flash/recall time 
is assigned through system or administration program- 
ming. 
TENANT SERVICE 
Two or more closely located sites can simultaneously 
be served by the same common equipment. Each site 
is provided with dedicated trunk facilities and separate 
feature and class of service complements. Also, refer 
to the discussion titled, SQUARE/NON-SQUARE SYS- 
TEM. Key mapping for line appearance can be per- 
formed on each station using the system or 
administration programming. 
TIMED HOLD RECALL 
After a call has been on hold for a programmed length 
of time, the system will recall the station that placed 
the call on hold. It also visually signals all other sta- 
tions. The audible signal is repeated at the end of 
each reoccurring time out period. The visual indication 
continues until the held call is picked up. The system 
or administration programming sets the timed hold 
recall time period. 
TOLL RESTRICTION - FLEXIBLE 
Flexible toll restriction can be programmed to prohibit 
some or all stations from calling a wide range of num: 
ber combinations while allowing specific exceptions. 
Restrictions are specified by up to four entries on a 
deny table while exceptions are specified by up to four 
entries on an allow table. Allow entries will always 
override deny entries. Up to eight digits are permitted 
for each entry. A “match anything” digit (# symbol) can 
be included as part of an entry to represent any digit 
from 1 to 0. This is used to deny or allow a range of 
numbers with one entry. A separate pre-programmed 
1+800 allow table permits this dialing feature to be 
selected regardless of any restrictions which may be 
specified. The dialing of 911 and 1+911 is always al- 
lowed. 
Once programmed, flexible toll restriction is assigned 
on a per line/per station basis. In addition to flexible 
restriction, or as an alternative to it, stations can be 
restricted with l/O call restriction assignment. When 
l/O call restriction is selected, l+ 7 digit dialing can be 
allowed if desired. Either system or administration 
programming is used to specify the deny and allow 
entries and assign the restriction to line and station.

TONE OR VOICE SIGNALLING 
(INTERCOM) 
Intercom calls can be tone signalled or voice signalled 
as desired. The tone signalled intercom call must be 
answered by lifting the handset. The voice signalled 
intercom call can be responded to in a handsfree man- 
ner. The class of service programming determines 
which signalling method is employed as the primary 
method when an intercom call is made. The alternate 
method is available through user action at the station. 
Intercom call progress is marked by special tone sig- 
nals. The system or administration programming 
determines which type of intercom signalling is first op- 
tion signalling for the system. Also refer to the discus- 
sions titled, INTERCOM CALL PROGRESS TONES 
and VOICE ANNOUNCE BLOCKING. 
ZONE PAGING (VIA STATION SPEAKERS) 
Zone paging allows groups of stations to receive an- 
nouncements through the station speakers. The 
programming can enable zone paging in up to three 
different zones. A station can be programmed to only 
receive announcements or programmed to originate 
announcements as well. Each station can be 
programmed to be in any or all zones for both receiv- 
ing and originating announcements. The ability of 
each station to originate and/or receive a page, and 
the arrangement of the paging into different zones are 
controlled by system or administration programming. 
Also, refer to the discussion titled, ALL-CALL PAGING 
(VIA STATION SPEAKERS).

INSTALLATION 
SECTION 1 
STANDARD INSTALLATION DETAILS 
MOUNTING CONSIDERATIONS 
The common equipment cabinet should be attached 
vertically to any sturdy, flat, surface or vertically rack 
mounted if desired. 
Cabinet must be located within six (6) feet of a 
proper electrical outlet. The system requires a 
dedicated 117VAC 15 AMP circuit, with a third-wire 
ground, supplied to a standard electrical outlet 
(NEMA 5-l!%). 
The distance between the common equipment and 
the TELCO/PBX jacks must be 25 feet or less as 
per FCC requirements. A nominal distance of 7 feet 
is recommended. 
The mounting location must be secure and dry and 
have adequate ventilation. The temperature range 
of the location must be within 32-l 22 degrees F 
(O-50 degrees C), and the relative humidity must be 
less than 90 percent non-condensing. 
If the mounting surface is damp or if it is concrete or 
masonry material, a backboard must be attached to 
the mounting surface to be used for common 
equipment mounting. Suitable mounting 
backboards are available commercially or can be 
constructed out of l/2-inch plywood cut to size. 
Tools and hardware required: 
Fasteners - wood screws (l/4 x 1 -inch round 
head), toggle bolts, or wall anchors 
Screwdriver -to match fasteners 
Electric drill - if prepared holes are required

MOUNTING PROCEDURE 
Unpack, and carefully inspect the common 
equipment and telephones for sh.ipping damage. 
Notify the shipper immediately of any damages 
found. Verify that the packages contain all parts 
and accessories needed for proper installation and 
operation. 
If a backboard is required at the mounting location, 
attach it securely to provide a stable mounting 
surface for the equipment. 
The common equipment is attached using three 
mounting holes located as shown on Figure 3-1. 
While refering to Figure 3-1, measure and mark the 
location of the mounting holes on the mounting 
surface. 
Drill holes in the mounting surface of a proper size 
to accommodate the hardware being used. If 
necessary, prepare these holes with inserts, 
anchors or other attachment devices as dictated by 
the type of mounting surface. 
Insert the top screws into the mounting surface, 
and tighten them to within approximately l/8-inch of 
the surface. 
Hang the cabinet 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. 
Insert a third screw through the mounting tab 
located on the lower edge of the cabinet and into 
the mounting surface, and tighten it into place 
Place the individual telephones as desired and in 
keeping with accepted industry and office 
standards. A telephone can be wall mounted if 
necessary as they are desk/wall reversible. 
Interconnect the system per the details shown in 
Tables 3-1 and 3-2 and Figure 3-3 shown at the 
end of this section

Installation 
AC POWER CONNECTION 
- Employ a dedicated 117VAC 15 AMP circuit, with a 
third-wire ground, supplied to a standard electrical 
outlet (NEMA 5-133) for the AC power connection. 
AC power connection is illustrated in Figure 3-2, 
shown on the following page 
l A plug-in power line surge protector should be 
installed between the power cord and the AC outlet. 
l Do not connect the AC power cord until the 
installation has been checked. 
l To apply AC power, connect the power cord to the 
electrical outlet. 
1 BATTERY BACK-UP 
The common equipment provides an interface 
connector for the connection of an optional external 
battery assembly. This assembly is available 
separately as a kit. 
l Connecting the optional Comdial external battery 
assembly to this interface provides a minimum of 1 
hour of operation should the AC power to the 
system be interrupted. 
Be sure that the AC power cord is 
connected to the electrical outlet before 
connecting the external battery assembly to the common equipment. This ensures 
that internal protection circuitry is 
operating to prevent damage which could 
result from improper connection. 
* During AC operation, the common equipment 
provides re-charging current to maintain the 
external battery potential at an operational level. 
NOTE: The optional external battery assembly 
requires approximately ten (IO) hours to 
completely re-charge to full potential after it 
has been completely discharged and, in some 
cases, when initially installed. 
SYSTEM GROUNDING 
The common equipment has internal secondary surge 
protection on all line ports. In order for this protection 
to be effective, the common equipment cabinet MUST 
be connected to a reliable earth ground such as a 
metal cold water pipe or a building frame ground 
System grounding is illustrated in Figure 3-2, shown 
on the following page. 
l The grounding wire must be of #lO or #12 insulated, 
solid copper and separate from the three-wire AC 
line cord. 
l A ground stud is located on the common equipment 
cabinet.

Figure 3-2. AC Power Connection and System Grounding 
LINE CONNECTIONS 
The common equipment cabinet line terminations are 
standard modular plug/jack connections. Each 
modular jack (2-6) provides termination for two lines. 
Modular jacks 2 and 3 also provide termination for an 
auxiliary pair in addition to the two outside lines. CO 
line terminations can be at a type 66M-xx connector 
block or at individual 6-position modular jacks. Table 
3-I shows the line connection details. 
The line cord that is routed between the CO line 
termination and the common equipment cabinet 
termination should be twisted-pair wiring. 
To help insure that external overvoltage 
surges do not damage the system, verify 
that gas discharge tubes or similar 
protection devices are installed, and 
properly grounded, on all connected 
outside lines. 
STATION CONNECTIONS 
l 
Connections between the common equipment and 
the stations for models NO61 6, N0820, and N1024 
are via two type 66M-xx connector blocks which are 
cable connected to the common equipment 50-pin 
male connectors. Table 3-2a shows the station 
connection detais. Station connections for the model NO308 are via standard modular plug/jack 
connections provided on the side of the common 
equipment cabinet. These jacks are labeled by 
station number. Table 3-2b details these 
connections. 
l The maximum distance allowed from the common 
equipment to the station when using #24 gauge, 
twisted-pair cable is 1500 feet. 
NOTE: If spare conductors exist in the cables that are 
run between the common equipment 66M-xx 
connector blocks and the station jacks, it is a 
good practice to connect them to earth ground. 
Doing this may help prevent them from 
inducing radio frequency and/or AC 
interference into the system. 
The polarity between the individual wires 
In a particular voice or data pair is not 
critical; however, do not connect the voice 
circuits to the data circuits. 
STATION PAIRING 
Station ports are paired for both data and overload 
protection as follows:
