have a voice mailbox. (2) It dials the intercom number of 
a station when a call is transferred to the voice mail unit. 
For example, if extension 100 transferred a call to a 
voice computer hunt group that used dial rule 3 and 
entered “200” in response to the system-generated 
prompt, the system would dial “200” when it transferred 
the call to the voice computer. 
3.75 Dial rule 4 - Ofiginzd Destination Extension: 
‘Es dial rule dials the original destination of the call. 
For example: If extension 200 dials a voice computer 
hunt group that uses dial rule 4, the system would not 
dial anything for this dial rule because there was not a 
“destination.” However, if extension 201 dialed exten- 
sion 200, which was forwarded to extension 202 which 
was forwarded to a voice computer hunt group that used 
dial rule 4, the system would dial “200.” Similarly, if 
extension 100 transferred a call to a voice computer hunt 
group that used dial rule 4 and entered “200” in response 
to the system-generated prompt, the system would dial 
“200” when it transferred the call to the voice computer. 
3.76 Dial rule 5 - Reserved for future use. 
3.77 Dial rule 6 
- Other IC/Contrullii IC: This 
dial rule is meant for conferencing features not implem- 
ented at this time. It is the opposite of dial rule 2. Where 
dial rule 2 would dial the intercom number of the station 
that brought the voice computer hunt group into the 
conference, this dial rule will dial the other intercom 
number that is involved in conference. This dial rule is 
meant to be used only during two-party calls. It is useful 
for features such as a “wake-up message* in which an 
operator in a hotel would receive a call from someone 
wanting a wake-up call. The operator could then invoke 
the “wake-up” feature and enter a time for the other 
person while in a conference on a call. 
3.78 Dial rule 7 - Hunt Group Number: This dial 
rule tells the voice computer which hunt group it serves 
(as an announcement or overflow station). For example, 
if a call overflows from hunt group 1 into a voice 
computer hunt group that uses dial rule 7, the system 
will send “01” to the voice computer. This dial rule is 
meant to be used for the voice computer performing 
announcement or overflow functions for one or more 
hunt groups. 
3.79 Dial rule 8 - Associated Tenant Group 
Number: 
This dial rule tells the voice computer which 
tenant group the originating extension is in. For 
example, if extension 200 is in tenant group 1 and it calls 
a voice computer hunt group that uses dial rule 8, the 
system will send “1” to the voice computer. 
3.80 Dial rule 9 - Associated Department Num- 
ber: This dial rule tells the voice computer which 
department the originating extension is in. For example, 
if extension 200 is in department number 1 and it calls a 
voice computer hunt group that uses dial rule 9, the 
system will send “1” to the voice computer. This dial 
rule can be used in conjunction with dial rule 8. 
3.81 Dial rule 10 - Associated Day/Nib&t Flag: 
This dial rule will dial a “1” if the originating 
extension’s tenant group is in day mode. Otherwise, it 
will dial “0.” This dial rule is useful for determining 
when the system is in night mode and indicating that the 
attendant station is therefore unavailable. 
3.82 Dii rule 11 -Associated Account Code: This 
dial rule will dial the account code, if any, that was 
previously assigned to a call. 
3.83 Dial rule 12 - Call ‘Qpe (K/CO): This dial 
rule will identify the type of call. If the call is an 
intercom call, the system will dial a “1” for this dial rule. 
Otherwise, this dial rule will dial a “2.” 
3.84 Dial rule 13 - Hunt Group Queue Position: 
This dial rule will identify the queue position the call 
was in (first, second, third...) while waiting for the hunt 
group. For example, if there was one other call ahead of 
this call when it overflowed to a voice computer hunt 
group that uses dial rule 13, the system would dial “2” 
for this dial rule. This dial rule is designed for features 
such as hunt-group overflow processing in which the 
recording tells the caller, “There are five calls ahead of 
your call.” This is especially useful for processing hunt 
group calls since the call does not lose its position in the 
hunt group when it is sent to the overflow station. 
3.85 Dial rule 14 - Hunt Group Overflow Count: 
This dial rule will dial the number of times that the call 
has been sent to the overflow station. If a call overflows 
to a voice computer hunt group with dial rule 14, the 
system will dial “1” the first time, “2” the second time, 
etc. This is useful for features such as hunt-group 
overflow processing in which the voice computer plays 
different messages or performs different types of 
processing depending upon the number of times a caller 
receives an overflow message. 
3.86 Dial rule 15 - Recall Source: This dial rule 
dials the intercom number of the station that received a 
transfer recall. The basic operation is the same as dial 
rule 4, except that this rule is intended for entering the 
voice mail system through a recall and dial rule 4 is for 
entry through direct dialing. It is useful for automated 
attendant applications to make the call transfer appear 
supervised.

4. TRUNKFEATURES 
4.1 This section explains the trunk functions and pro- 
grammable features. Trunk capacities are explained in 
SPECFICATIONS on page 2-2. 
NOTEREGARDING TRUNK SECURITY 
While this system is ~desigued to be reasonably 
secure against CO trunk misuse by outside callers, 
there is no implied warranty that it is invulnerable to 
unauthorized intrusions and toll fraud. If the central 
office does not provide supervision, and disconnect 
the call when one party hangs up, it is possible for a 
caller to remain connected to a CO trunk circuit. If 
this happens, and the caller begins dialing, the call 
could be placed through the 416/832 System and 
would then be billed to the system’s owner. The sys- 
tem cannot check this type of call for toll restriction 
and may not register the call in SMDR This prob- 
lem could arise when a call is connected to a station, 
when a call is in an unsupervised conference, when 
a call is forwarded or transferred to the public net- 
work, or when DISA is used for placing outgoing 
calls. 
To determine if disconnect supervision exists on a 
trunk, disable “standard” tones for trunks in the 
database. Then place a call to an outside party using 
the trunk to be tested and have the called party hang 
up while you remain off hook. If there is disconnect 
supervision, you will hear 416/832 dial tone within 
30 seconds. If you hear telephone company dial 
tone, there is no supervision. If supervision does not 
exist, contact the telephone company to determine 
if it can be enabled. Centrex and loop start trunks 
frequently do not provide disconnect supervision. 
To make a loop start trunk more secure, a loop-to- 
ground start converter can be installed. Each trunk 
should be checked when it is first installed and peri- 
odically rechecked to reduce the probability that the 
trunk will be used for unauthorized calls. 
A. DUAL-TONE MUIXI-FREQUENCY 
(DTMF) OR DIAL-PULSE SIGNALING 
4.2 Trunks can be designated for MMP or dial-pulse 
signaling through database programming (see PRO- 
GRAMMING, page 5-103). 
4.3 A digital code is generated by the keysets and de- 
coded by the system to be sent as either a MMP or dial- 
pulse signal, depending on the trunk designation. Keysets and IYfMP single-line sets can be used on either 
typeoftrullk. 
4.4 A non-AlMJnondigitalJnon-DVK keyset user or 1 
DIM? single-line set user can switch from dial-pulse to 
M’h4P signals, while using a dial-pulse trunk, by press- 
ing the pound (#) or asterisk (*) keys. After the pound or 
asterisk key is pressed, all digits that follow during that 
call are sent out as IYI’IW tones. (This is useful when 
calling computerized services that require a MMP tele- 
phone, such as automated banking.) 
NOTE: Inter-Tel AIM keysets and digital keysets do not 
require this procedure; MMP is enabled once the call m 
has been established. Inter-Tel/DVK keysets send both 
digital code and M’h4P tones; therefore, this procedure 
is also not required when using a DVK keyset. 
B. OUTGOING-ACCESS, ALLOWRD- 
ANSWER, AND RING-IN ASSIGNMENTS 
4.5 Each trunk group has programmed lists of stations 
for outgoing-access, allowed-answer, and ring-in as- 
signments for day and night modes. 
l Outgoing-access assignment for a particular trunk 
group permits the station user to place calls using 
trunks in that trunk group. 
l Allowed-answer assignment for a particular trunk 
group permits the station user to answer incoming 
calls on the trunks in that trunk group. Although the 
call can be answered, it does not ring or flash at the 
user’s station. 
l Ring-in assignment for a particular trunk group per- 
mits the station user to receive direct ring-in calls on 
trunks in that trunk group. The station rings and, on 
keysets, the individual trunk or call key flashes. Al- 
lowed answer for the trunk group is automatically 
assigned to a station with ring in. 
4.6 When keyset stations have outgoing-access or 
ring-in assignments, the associated individual trunk 
keys show the status of their trunks. Stations that do not 
appear on any of the lists cannot place or directly receive 
outside calls; they are limited to intercom calls, confer- 
ences, transferred calls, and retrieving calls on system 
hold. (A call on system hold can only be picked up at the 
station that placed it on hold or at a station with an indi- 
vidual trunk key for the trunk.) 
4.7 A private trunk group (with one or more trunks) 
can be established by programming outgoing-access, 
ring-in, and allowed-answer assignments for the trunk 
group to only one station.

4.9 Ring-in/answer patterns can be set up and 
assigned to the trunk groups, DID numbers, and auto 
ring-in E&M trunks (when they are not designated for 
ring-in to a single station, a hunt group, or DISA). There 
can be 40 patterns in a standard system and up to 60 in an 
expanded system. These patterns designate the stations 
that will receive direct ring-in, and/or have allowed-an- 
swer permission for the trunks. 
D. 
RINGZONES 
4.10 The system power supply’s ring generator can 
provide ring voltage to ring up to 20 AC-ringing single- 
line stations simultaneously without any noticeable 
change in the ring tone. To preserve the ring tone quality, 
single-line stations should be divided into ring xone 
PUPS- 
4.11 Most central office ring signals follow a 2 second 
on/4 second off pattern that could be represented by this 
drawing: 
1214) 
4.12 Ring xones 1,2, and 3 use this pattern, but the 
“on” times are shifted so that only one zone is ringing at 
a time. 
ZONE1 
ZONE2 
ZONE3 
4.13 The system is constantly cycling through this 
timing pattern. When a call rings in, the xone that will 
receive ringing first depends on where the system is in 
the cycle. For example, if a call rings when the system is 
three seconds into the cycle (as shown below), the sta- 
tions in zone 3 would begin ringing one second later. 
Zone 1 would ring three seconds after the call was re- 
ceived, and xone 2 would ring after 5 seconds. 4.14 There is an immediate-ring option that provides 
ringing as soon as the call is received, regardless of the 
cycling described above, When the system is in the de- 
fault state, all single-line sets are set for immediate ring- 
ing- 
4.15 If there sre fewer than 20 AC-ringing single-line 
sets that would ring at once, they can all be placed in the 
immediate ring zone. If there are more than 20, they 
should be removed from the immediate xone and di- 
vided up among xones l-3 so that no more than 20 sets 
ring at once. Be sure to check all ring-in patterns in day 
and night modes to ensure that ring zone assignments do 
not allow more than 20 
AC-ringing single-line sets to 
ring at once. 
E. SIGNAL DEVICES 
4.16 The 
Matrix card contains four relays and the Ex- 
pansion Card contains four relays. Up to seven of the re- 
lays can be used to activate an external signaling device 
when a call rings in on one of the assigned trunks. The 
signal follows the 2 seconds on/4 seconds off pattern. 
Ring-in can be programmed for day and/or night modes 
by placing the relays in the desired ring-in/answer pat- 
tern(s). For more information, refer to page 2-14 in 
SPEClFICATIONS. 
F. DAY AND NIGET MODES 
4.17 
There are separate lists in the database for toll re- 
striction, outgoing access, allowed-answer, and ring-in 
assignments for day and night modes. When an atten- 
dant enters the Night Mode feature code, the associated 
tenant group uses the night lists. When the primary 
attendant enters the Night Mode feature code, all tenant 
groups are placed into night mode. When the primary 
attendant cancels night mode, all tenant groups are in 
day mode. 
4.18 There is no attendant recall during night mode. A 
call will recall the station that transferred it or put it on 
hold and will ring there until the Recall and Abandoned 
Call timers expire; then the system will disconnect the 
call. 
Night Switch Relays 
4.19 
The Matrix and Expansion Cards have program- 
mable relays. If desired, one or more can be designated 
for night switch operation. Night switch relays are acti- 
vated when the system is placed in night mode. They can 
be used for controlling lights, alarm systems, or other 
electrical devices. Night relays are programmed in the 
database (see page 5-73 in PROGRAMMIN G, and page 
2-14 in SPEClFICATIONS for more information).

G. TRUNK RESTRICTION AND STATION 
TOLL RESTRICTION 
4.20 Trunks and stations can be toll restricted using 
several methods. Trunks can be “subject to toll restric- 
tion” or “unrestricted.” They can also be identified to al- 
low equal access dialing and/or to absorb digits. Stations 
can be toll restricted using a combination of eight station 
class of service (SCOS) restrictions and/or they can be 
restricted from accessing specific trunk groups. Each of 
the trunk and station restrictions is described separately 
in the following paragraphs. 
‘hunk Restriction 
4.21 
Trunk group access is programmed on a station- 
by-station basis. Individual stations can be allowed or 
denied access to each trunk group separately for day and 
night modes. In addition, each trunk group can also be 
designated as “subject to toll restriction” or “unre- 
stricted” in database programming. (All trunks are sub- 
ject to toll restriction when the system is in the default 
state.) When a station user selects a trunk that is desig- 
nated as subject to toll restriction, the system checks the 
database for that station’s SCOS. When an unrestricted 
trunk is chosen, the station’s SCOS is not checked and 
dialing is not required to hold the trunk. 
4.22 TNI& groups are often programmed as unre- 
stricted to allow station users to have access to reduced- 
cost long distance carriers, or to use ringdown lines, 
dictaphones, voice mail systems, and other auxiliary 
equipment. When the installer is Programming unre- 
stricted trunks, one of four call cost factors can be 
selected to designate calls as free, local, ten-digit toll, or 
operator/international. The selected call cost is then 
used for all calls that are placed using that trunk. 
Trunk Group Exemption From LCR Only 
4.23 The trunk group may be designated as “exempt 
from Least-Cost Routing (LCR) only.” This allows 
users with SCOS 6 (LCR Only) to directly access speci- 
fied trunk groups by pressing the appropriate trunk 
group keys (or the ANSWER key for auto trunks) or by 
entering the appropriate TNII~ Croup Access feature 
codes. This feature is required if trunks are connected to 
auxiliary equipment, such as voice mail, dictation, or 
ring-down equipment. When such trunks are designated 
as exempt from LCR Only, stations with SCOS 6 and al- 
lowed access can use the special facilities. 
4.24 Designating a trunk group as exempt from LCR 
Only also allows LCR-Only stations to use the Call For- 
ward To The public Network feature. To do this, station 
users can enter a trunk group access code when pro- 
gramming the call forward number. 4.25 The default assignment for all trunks is 
nOt 
exempt 
from LCR Only. It is a system-wide designation. 
That is, if a trunk group is subject to LCR Only, all sta- 
tions with SCOS 6 are denied direct access to the trunks. 
Absorbed Digits 
4.26 
Restricted trunk groups can be programmed to 
“absorb” or ignore the first digit(s) dialed so that only 
the remaining digits are checked for toll restriction and 
call cost purposes. There are two applications for this 
feature: PBX (E&M network) installations and installa- 
tions in areas where part of the local office code is ab- 
sorbed by the central office. 
4.27 When using a dial-repeating E&CM trunk, a 
416/832 station user must dial an E.&M trunk access 
code to reach the other telephone system, then that sys- 
tem’s trunk access code to place a call using its trunks. 
The 416/832 System must absorb the second code (the 
one that accesses the other system’s truuk) to allow 
proper toll restriction. Without absorbed digits, the 
416/832 System cannot perform the toll restriction and 
call cost functions. However, with absorbed digits, the 
416/832 System absorbs the other system’s trunk access 
codes, checks the remaining digits for toll restriction, 
and calculates call cost. 
4.28 When a number is dialed that does not match one 
of the absorbed digit strings (up to 50 strings, with a 
maximum of 12 digits in each string), it is considered to 
be an intercom call in the other telephone system, toll 
restriction is passed, and the call is designated as a free 
call (000) in the SMDR report. When redialing or using 
call forward, the system automatically inserts a short 
pause after the E&Mtrunk access code (which is entered 
as part of the call forward number). When speed dialing, 
the speed-dial number must include the other system’s 
trunk access code and a pause before the telephone num- 
ber. 
4.29 In some rural areas, specific digits (dialed as all 
or part of the local exchange) are absorbed by the central 
office, thus reducing the number of digits required to 
dial local calls. These digits may also be “repeatable.” 
That is, they are absorbed if dialed more than once. To 
determine if a central office absorbs digits and whether 
they are repeatable, contact the telephone company. 
4.30 If the system is not programmed to recognize the 
absorbed digits, two problems may arise. One Problem 
is that a telephone number of fewer than seven digits, 
that is dialed at a toll-restricted station, is not recognized 
as a valid telephone number and the call is dropped. The 
other problem is that toll restriction can be defeated by 
dialing the absorbed digits before dialing a toll number. 
However, when programmed to recognize a single 
string of absorbed digits (with up to 12 digits in the 
Page 4-26  
						

							INTER-TELPRACTICES 
IMX/GM.X 416/832 INST4LLATION & MAINTENANCE 
Issue 1, Nov%% 
string), the system checks the remaining digits for toll 
restriction and processes numbers with fewer than seven 
digits as local calls (except 411 calls, which are consid- 
ered seven-digit toll calls). If the first non-absorbed 
digit is ‘1” or “0,” SCGS 1,2, and/or 8 are enforced im- 
mediately (see SCOS, beginning in paragraph 4.34). 
Absorbed digits appear in the SMDR record when 
dialed if they are not repeatable or suppressed. 
4.31 The absorbed-digit designations are pro- 
grammed on a trunk group-by-trunk group basis. No 
trunk groups are designated for absorbed digits when the 
system is in the default state. Refer to page 5-113 in 
PROGRAMMING for more information. 
Equal Access 
4.32 With equal access, the customer must choose a 
primary long distance carrier. This is the carrier that will 
automatically be accessed when the user dials a long 
distance telephone number. Customers may also select a 
secondary carrier or use several secondary carriers. 
These secondary carriers are accessed by dialing the 
equal access prefix (10 or 101) and a three- or four digit 
code assigned to the desired carrier (XXX or m 
before dialing the telephone number. When using a sec- 
ondary carrier, the telephone number is dialed as usual 
after the equal access code 
-including the toll field (1, 
0, or 01) and the area code, if needed. 
433 A restricted trunk group that does not have equal 
access designation prevents the system from providing 
accurate toll restriction and call cost information when 
m “10xXx” or “101xxxX” is dialed on a trunk in that 
trunk group. When programmed for equal access, the 
system ignores the equal access code and checks the re- 
maining digits for toll restriction. Equal access designa- 
tion is programmed on a trunk groupby-trunk group 
basis. All trunk groups are designated for equal access 
when the system is in the default state. To limit access to 
specific secondary carriers, the stations can be restricted 
to using LCR only. 
Station 
Class of Service (SCOS) 
434 SCOS is programmed on a station-by-station ba- 
sis and each station can have different restrictions for 
day and night modes. A station can be completely unre- 
stricted (SCOS 0) or can have any combination of the 
following restrictions. 
4.35 scos 1 - Operator restriction: Calls that 
begin with a “0” are restricted. This also restricts in- 
ternational calls. 
NOTE: If this restriction is not set, and a user dials “0” 
as the first digit when placing a call, only SCOS 3 is 
checked; no other toll restriction is checked. 
CAUTION 
REGARDDIG EMERGENCY NUMBERS 
In areas where the emergency number is 1911, be 
sure that toll-restricted stations have SCCX 8 (En- 
able ALD) and that 911 is in the allowed long dis- 
tance number list. Otherwise, toll-restricted users 
may not be able to find a station that is permitted to 
dial “l+” numbers. Note that 911 is allowed at every 
station regardless of toll restriction, but 1911 re- 
quires this special programming. 
4.36 SCOS 2 -Toll access restriction: This restricts 
calls that begin with 
“1” unless they are on the allowed 
long distance number list and the station has SCGS 8. 
437 SCOS 3 -International call restriction: Calls 
that begin with “01” are restricted. 
NOTE: If international calls are allowed (SCGS 1 and 
SCOS 3 are not set) and the user dials “01” as the first 
digits when placing a call, no other toll restriction is 
checked. 
438 SCOS 4 - Eiiht-diiit call restriction: Calls 
are not permitted if they are over seven digits in length, 
unless they are in the allowed long distance number list 
and the station has SCOS 8. Users with this SCGS must 
dial a valid telephone number before the appropriate In- 
terdigit timer expires; otherwise the connection will be 
dropped and the user will hear reorder tones. 
4.39 SCOS 5 - Aria/office code restriction: This 
restriction is divided into user groups to allow different 
area/office code restriction tables for each of the user 
groups (up to eight groups in a standard system, up to 12 
in an expanded system). This is useful for reducing re- 
strictions for some of the station users while increasing 
restrictions for others. Each station is assigned to a user 
group in database programming. Within each user 
group, area codes can be designated as restricted, al- 
lowed, or extended. Restricting an area code prevents 
users from placing calls to that area code. Allowing an 
area code also allows all office codes within that area 
code. Designating an area code as extended allows the 
programmer to determine which office codes (up to 800) 
are allowed or restricted within that area code. For each 
user group, 800 area codes can be marked as allowed or 
restricted in the database list, and up to four area codes 
may be marked as extended. 
4.40 SCOS 6 
-LCR Only: Calls can only be placed 
using the Least-Cost Routing (LCR) feature when this 
restriction is assigned. The user will hear reorder tones 
when attempting to place a call using any other method. 
A restricted user can still access individual trunk groups 
if the trunk groups are designated as “exempt from LCR 
Page 4-2’7

Only” (as described on page 4-26), or were transferred, 
were placed on hold, or are recalling or ringing. LCR- 
Only stations access only the facility groups assigned 
(see page 4-33 for more details). Trunk restriction de- 
termines which trunk groups in the facility group can be 
accessed by the station. Because 
stations with this 
SCOS can use only LCR, they camtot forward calls to 
outside telephone numbers (unless they are using a trunk 
group designated as exempt from LCROnly). For more 
information on LCR, refer to page 4-32. 
4.41 SCOS 7 -Alternate carrier number Ipstric- 
tion: 
Calls can not be placed to any of the numbers on 
the alternate carrier number list if the station is given 
this restriction. (For ‘example, to restrict 411 at certain 
stations, enter the number in the alternate carrier list and 
give the stations SCOS 7.) There can be up to 20 alter- 
nate carrier numbers with up to 10 digits each. The num- 
bers should not contain the toll field, but can contain 
equal access digits (e.g., do not enter l+ or Ot numbers, 
except 10xXx and 1OlXXXX numbers). An “X” in a 
number represents any digit O-9. 
NOTE: Allowed long distance numbers override alter- 
nate carrier number restrictions. Also, numbers are only 
restricted if they 
exactly match the number on the alter- 
nate carrier list. For this reason, alternate carrier num- 
bers can have a plus (+) added to the end of the number 
to restrict users from bypassing toll restriction by dial- 
ing extra digits after dialing the alternate carrier num- 
ber. For example, 976+ restricts all calls that begin with 
976. 
4.42 SCOS 8 
- Allowed long distance number: 
Stations with this SCOS are allowed access to numbers 
in the allowed long distance number list. There can be 
up to 20 numbers (30 in expanded systems) of up to 10 
digits each. Calls placed to these numbers are not sub- 
ject to SCOS restrictions 2 and 4-7. Operator-assisted 
and international calls (SCOS 1 and 3) are not checked 
against this list. An “X” in the number represents any 
digit O-9; for example, xXx-555-1212 allows users to 
dial directory information using any area code. A plus 
(+) in the number allows any number that begins with 
the designated sequence (for example, 800t allows any 
800 number to be dialed). The numbers should not 
include the toll field. 
Class-of-Service Account Codes 
4.43 SCOS can be programmed to be associated with 
account codes. This permits a user to place a call from 
any station using his class of service account code to en- 
able his usual SCOS. When a class-of-service account 
code is entered, the system checks the associated station 
and applies its SCOS to the call being made (trunk ac- cess permission and LCR advance class-of-service are 
not applied). When the call is completed, the pro- 
grammed SCOS for the station being used goes back 
into effect. The call appears in the SMDRreport as being 
placed from the station beingused, and the account code 
will appear unless an optional account code is entered 
later (during the call). 
Speed-Dial Override & Tell Restriction 
4.44 System speed-dial numbers can be programmed 
to bypass SCOS restrictions on a system-wide basis. If 
the option is not enabled, all system speed-dial numbers 
are subject to toll restriction. 
North American Numbering Plan (NANP) 
4.45 The growth of telecommunications services has 
created an increasing demand for more telephone num- 
bers. To meet the demand, Bcllcore has prepared a long- 
range North American Numbering Plan (NANP) to 
provide additional telephone numbers. The plan ex- 
pands the capacity of the current numbering system by 
making area and office codes interchangeable. That is, 
numbering patterns formerly reserved for office codes 
can be used as new area codes, and office codes within 
existing area codes can have the same pattern as other 
area codes. 
4.46 With interchangeable codes, switching systems 
lose the ability to distinguish between 7- and lOdigit 
numbers by examining the first three digits. To address 
this, three methods have been proposed: 
0 The Prefix method requires a 1 before a lo-digit 
number, and does not allow 1 before 7digit num- 
bers. 
0 The Timing method requires the switch to wait 
approximately four seconds after seven digits have 
been dialed to see if additional digits are received. 
0 The Hybrid method requires timing only if a 0 or 1 is 
dialed before a 7digit number that begins with three 
digits that could be an area or office code (use the 
NXX pattern described below). 
4.47 The former dialing pattern required an area code 
to be in the “NZX” format, where N=2-9,Z=O or 1, and 
X=0-9. The new numbering plan allows the area code 
format “NXX,” which is the current office code format. 
Therefore, with the new numbering plan, more area and 
office codes will overlap. 
4.48 The following chart illustrates the difference be- 
tween the new Numbering Plan Analysis (NPA) and 
each of the overlap flags. In the chart, N=2-9,Z=O or 1, 
and X=0-9.

4.49 
In order to properly process the new NRA, four 
flags have been added to the system database. During 
database programming the programmer can specify the 
following non-standard numbering plan information: 
0 Office Codes Used as Area Codes: An area code in 
another location uses an NXX pattern that matches 
an of5ce code within the system site’s area code. 
(This flag defaults to no.) 
l Area Codes Used as Office Codes: One or more of- 
fice codes within the system site’s area code use an 
NW pattern that is the same as an area code in 
another area. (This flag defaults to )u) unless you are 
converting a database that has the “Overlap Area/ 
Office Code flag enabled.) 
0 Toll Digit Allowed On Toll Local Calls: This op 
tion applies only if the area and office codes overlap. 
Callers in the site’s area code usually dial a 1 when 
placing a call within the local area code(s). (This 
flag defaults to no.) 
l Toll Digit Required On Toll Long Distance Calls: 
This option applies only if the area and office codes 
overlap. Callers in the site’s area code must dial a 1 
when placing a call outside of the local area code(s). 
(This flag defaults to yes.) 
4.50 Area code lists in the database, for toll restriction 
and LCR, include all 800 possible area codes. All area 
codes are allowed in toll restriction and are included in 
LCR Route Croup 1 when the software is in the default 
state. (In upgrades, only the new area codes default to 
allowed in toll restriction, and they are included only in Route Croup 1. All other area codes remain as pro- 
grammed.) 
NOTE: Toll restriction SCOS 4 (Restrict Eight-Digit 
Calls) is affected by the area/office code database nags 
and toll digit nags. The area/office code flags must be 
set properly on the system in order for toll restriction to 
work correctly for the given site. The 
system must know 
whether the area and office codes overlap and whether 
toll digits will be dialed to properly detect end of dialing 
and apply toll restriction. For example, if you have the 
system set to look for a toll digit (1) on toll long distance 
calls on a system where area and office codes overlap, 
and the station user placing a call does not dial the 1 
(dials 213-555-1234 instead of l-213-555-1234), the 
system will allow the call and will consider end-ofdial- 
ing to be after the seventh digit, as if the user was dialing 
a local non-toll call. However, if the station user dials 
1-213-555-1234, the call will bc restricted as usual af- 
ter eight digits are dialed. 
Home And Local Area Codes 
4.51 
In many areas, the telephone company has 
created call-cost arrangements that refer to “home” and 
“local” area codes. The home area code is the area code 
within which the system resides. The local area codes 
are additional area codes that, when called, use the local 
or toll local call-cost rate instead of the long distance 
rate. Up to three local area codes can be programmed 
and then extended within toll restriction programming 
to provide proper call costing. 
4.52 The local area codes can be programmed as “Ex- 
tended” area codes to allow or restrict specific office 
codes within them and to label the office codes’ call cost 
as “local” or “seven-digit toll.” If the home or local 
codes are extended in User Croup 1, the system will use 
the call cost designations for that extended area code 
whenever a station (in any user group) places a call us- 
ing that area code.

H. OPTIONAL WEEKLY TOLL LIMITS 
NOTE: This feature is available only in the Extended 
package and is enabled only by Inter-Tel Services per- 
sonnel. The system must have a modem that allows re- 
mote access. 
4.53 When enabled, the Weekly Toll Limit feature 
keeps track of the accumulated call cost for specified 
types of toll calls. The feature can monitor 7- and 
Xl-digit toll calls and/or operator-assisted/international 
calls that are placed by station and DISA users. 
4.54 The database is programmed with a weekly 
dollar limit for each type of call being monitored. This 
value can range from $0-$65,000. Each time a moni- 
tored call is placed, the call cost 
is added to the total. 
4.55 If the total cost of monitored calls reaches 80% of 
the weekly limit, the system sends an alarm message to 
alarm stations and the SMDR that states TOLL 
SECURITY LIMIT AI 80%. 
456 When the weekly limit is reached, the system 
sends another alarm message that states TOLL 
SECURITY LMlT EXCEEDED. The monitored types 
of calls (7/10-d@ or operator/international) will not be 
allowed until one of the following occurs: 
l The weekly limit is set to a higher value through da- 
tabase programming, as described on page 5-97. 
l The weekly accumulated total is reset to zero 
through programming, as described on page 5-97. 
l The weekly accumulated total automatically resets 
to zero at the end of the week (1201 am Sunday). 
4.57 If a station is forwarded to a toll number that is 
being disallowed due to the weekly limit being exceed- 
ed, calls will be handled as follows: 
l An intercom caller hears busy tones. 
l A direct ring-in outside call rings at the station until 
the Transfer Available or Transfer Busy timer ex- 
pires before being sent to the primary attendant. 
l Calls through DISA or an automated attendant ring 
at the station until the Transfer Available timer ex- 
pires before being sent to the appropriate recall des- 
tination. 
l Transferred calls remain at the transferring station. 
0 Calls from a voice computer are sent to the atten- 
dant. 
4.58 Weekly toll limit information can be changed 
only after the Database programming feature code (029) 
has been entered at an attendant station. The program- 
ming privilege will remain in effect until the end of the 
programming session. When the data has been changed, 
a system alarm shows TOLL SECURITY DATA 
CHANGED at alarm stations and in SMDR. For 
programming information, refer to page 5-97 in 
PROGRAMMING. 
NOTE: If the “Remaining Days” value is 0, weekly toll 
limit database information cannot be updated. 
4.59 The Weekly Toll Limit feature is enabled by 
Inter-Tel Services personnel. The database contains a 
prompt that indicates the remaining days that the 
weekly toll limits will be in effect. This value automati- 
cally decreases by one each day. When the “Remaining 
Days” value reaches 0, the Weekly Toll Limit feature is 
disabled and calls are no longer monitored. A system 
alarm indicates TOLL SECURITY FEATURE EX- 
PIRED. Users trying to place monitored calls will see a 
display that says CALL FAILED - TOLL LIMIT 
EXCEEDED. To enable the feature again, Inter-Tel 
Services personnel must reset the “Remaining Days” 
value. (See page 6-41.) 
NOTE: If a system database restore is performed, the 
Remaining Days value of the Toll Security WeeklyLim- 
it feature is reset to 0. It is not restored to its previous val- 
ue.

I. TRUNK GROUP ASSIGNMENTS AND 
AUTOMATIC ANSWER/SELECT 
4.60 
Each trunk is assigned to 1 of 102 possible trunk 
groups (142 in expanded 832~port systems). Trunk 
groups are assigned to specific tenant groups to deter- 
mine which attendants will place the trunk groups in 
night mode. A trunk group can also be designated for 
auto trunk selection (using the ANSWER key as de- 
scribed in paragraph 4.62) for a tenant group. 
l Trunk Group feature codes and trunk group keys are 
used to select a trunk in one of the programmed trunk 
groups -up to 142 groups. Each trunk must be as- 
signed to a trunk group. For example, all local trunks 
could be in one group, while another group contains 
Wm trunks that are used for long distance calling. 
Unused trunks can be assigned to a single trunk 
group labeled “unused.” Trunk Group feature codes 
are necessary when forwarding calls to outside num- 
bers. 
0 Auto trunks are incoming or outgoing trunks (up to 
344 in standard systems, up to 696 in expanded sys- 
tems) that are accessed by entering the Automatic 
Trunk Selection feature code (89) or by pressing the 
ANSWER key. 
4.61 Automatic Ihmk Answer: If a station is pro- 
grammed with allowed-answer assignment only (no 
ring-in) for a trunk group, direct ring-in calls on that 
trunk group can be answered by entering the Automatic 
Trunk Answer feature code (350) or pressing the flash- 
ing individual trunk key. 
4.62 Automatic lhmk Select: For calls that are ring- 
ing or holding at the station, the user may enter the Auto- 
matic 
TN& Selection feature code (89) or press the 
ANSWER key. When more than one call is ringing or 
holding, the following priority list determines which 
call is answered first: 
Ringing outside calls (ring ins, recalls, callbacks, or 
transfers) are answered in the order they were re- 
ceived. 
Then calls on individual hold are answered (not calls 
on system hold, conference hold, or being trans- 
ferred). Calls are picked up in the order they were 
placed on hold. 
If no calls are ringing or holding, an available outgo- 
ing auto trunk is selected (unless the station is re- 
stricted to using Least-Cost Routing Only or is 
restricted from the trunk group).
