12. LEAST-COST ROUTING (LCR) 
12.1 Programming LCR requires some preparation. 
Refer to page 4-32 in m for a description of 
the feature. Then, follow the planning steps listed be- 
low. For a program plamring sheet, refer to Figure S-23, 
on page 5-228. 
Facility groups: Determine the types of trunk 
groups 
available and assign them to up to 24 facility 
groups (32 in an expanded system). For example, 
place all local trunk groups in one facility group, in- 
state WAIS in another, etc. Each facility group can 
contain any or all of the system trunk groups. 
NOTE E&M trunks can be placed in LCR facility 
groups to allow the system to route outgoing calls 
through the E.&M destination site’s trunks. The 
E&M trunks are put into the facility groups and the 
dial rules are programmed to dial the other system’s 
trunk access code and then echo the digits dialed. 
This is useful when calls that are toll calls from the 
416/832 site can be placed as local calls through the 
other site’s trunks. 
Area codes and offrce codes 
to be accessed by 
LCR: 
Customers may wish to use LCR for all outgo- 
ing calls, all long distance calls, or calls to specific 
cities. List the area codes to which the customer 
wishes to place calls using LCR. Also list office 
codes within the area codes for more specific LCR 
use. 
Route groups: Croup the area codes and offtce 
codes that have common access in up to 19 route 
groups. For example, non-toll local area and office 
codes can be in one group, while toll codes are in an- 
other. A route group for “800+” calls could also be 
programmed. (Route group 1 is used for 911 and 411 
calls and is normally used for non-toll, local calls 
and calls to the telephone company operator.) To 
provide route groups for calls that begin with 
0, 01, 
and 011, there are three permanently programmed 
route groups (these route groups cannot be deleted): 
- Route Croup 17 is for operator-assisted (0+) 
CSllS. 
- 
Route Croup 18 is for operator-assisted inter- 
national (Ol+) calls. 
- Route Croup 19 is for station-to-station inter- 
national (Oil+) calls. 
NOTE: Because area and office codes do not need to 
be checked when these route groups are used, only 
facility groups and time blocks are programmed for 
them. 
Rank the facility groups within the route groups: 
Each route group is divided into day, evening, and night/weekend time blocks. Rank the facility 
groups, from most- to least-economical, for each 
time block. For example, direct-dial trunks may be 
the least-economical route during the day, but at 
night they may be the most-economical route. A fa- 
cility group can appear in more than one route group. 
Dial rules needed: If the trunk groups in the facility 
groups require special digits (for example, SCC 
access codes), up to 28 dial rules can be pro- 
grammed. In addition, there are four permanently 
programmed rules in the database; they are as fol- 
lows: 
- 
Dial Rule 1 -Echo toll field: When LCR is 
selected, the station user dials the number as if a 
direct dial trunk was being used, including the 
area code and “1” if necessary. If LCR selects a 
trunk that requires a “1,” its facility group must 
have this dial rule programmed to tell the system 
to echo (send) the “1”. 
NOTE: It may be desirable to program dial rule 
number five to add a “1,” even though dial rule 
number one can be used to echo the toll field. 
This allows users to dial without knowing 
whether the “1” is required. If”1” is needed, the 
dial rules tell the system to add it. Users only 
have to remember to dial the area code whennec- 
essary. 
If dial rule number five is programmed as 
described, do not include dial rule number one. 
- 
Dial Rule 2 -Echo anza code: The system 
includes the area code in the number if this dial 
rule is programmed for the facility group. If this 
dial rule is not programmed, the system drops the 
area code from the dialed number. 
- 
Dial Rule 3 -Echo local address or country 
co& and national number: All 
facility groups 
must have this dial rule. It tells the system to send 
the seven-digit telephone number that the user 
has dialed. 
- 
Dial Rule4 -Echo ExtensionNumber: This dial 
rule includes the extension number of the station 
placing the call in the dialed number. This is es- 
pecially useful in areas where the 911 operator 
needs to know the extension number when an 
emergency call is placed from a business loca- 
tion. 
Assign the dial 
roles to the facility groups: List the 
dial rules 
for the facility groups in the order they are 
to be used. For example, to add the “1” (rule 5), echo 
the area code (rule 2), and echo the telephone num- 
ber dialed (rule 3), enter 5, 2,3. (For international 
calls, only rules 1 and 3 are needed.)

NOTE: Calls placed to 911 and 411 are automatically 
routed through Route Group 1. This route group is nor- 
mally used for local calls. 
12.4 FACILITY GROUPS: The Facility Groups list 
box shows each of the 
group numbers (01-32) and its de- 
scription. Facility groups must be programmed with 
lists of trunk groups (or a single trunk group) and dial 
rules. 
A trunk group can appear in more than one facility 
group, but not all trunk groups need to be assigned. Any 
combination of up to 32 of the system dial rules can be 
assigned to each facility group (up to 48 digits can be 
dialed). 
To program trunk group and dial rule lists for a 
facility group, select the

trunk group in a separate facility group, place those facility groups in the same route groups, and ensure 
that stations have sufficient LCR advances to reach 
the trunk groups. For toll restriction purposes, only 
the highest 
numbered trunk group in the facility 
group is checked (the last trunk group in the list). 
Make sure that the highest numbered trunk group 
has the desired toll restriction programming for the 
entire facility group.

5-24, beginning on page 5-235. 
A. INDMDUALTRUNK(lNJIT) 
13.3 
When you select Individual Trunk from the 
Trunk Progr amming menu or enter the INM’ command, 
thewindow shown on the next page appears. 
13.4 For each trunk, determine the following informa- 
tion. (Program planning sheets for trunk programming 
are in Figure 5-24, beginning on page 5-235.): 
Identify the trunk group to which it will belong. 
Each trunk nr~? be assigned to a trunk group. They 
can be moved from group to group, but cannot be re- 
moved from groups entirely. 
If any trunks will be un- 
used, they should be assigned to a trunk group la- 
beled UNUSED that does not have a ring-in assign- 
ment associated with it. 
Receive and transmit gain can be adjusted on a 
trunk-by-trunk basis if voice transmit or voice 
receive volume problems occur. You can adjust the 
receive gain and/or the transmit gain for individual 
circuits. Receive and transmit are measured from the 
perspective of the central office. That is, 
receive 
gain 
adjusts the signal that is sent to the COjbm the 
4161832 System. The signal that is transmittedfrom 
the CO 
is affected by adjusting the transmit gain on 
the 4161832 Svstem. 
d 
Hybrid balance can be set to ideal, loaded, or 
unloaded on a trunk-by-trunk basis. (I’1 circuits and 
4-wire E&M circuits cannot be hybrid balanced.) 
- 
Ided: The ideal balance network simulates a 
6OO-ohm transmission line to match trunks, 
which are supplied by other equipment located 
within the same building, using private, copper 
wire termination (e.g., an OPX supplied by 
another PBX that does not use the 
public network 
or a Tl channel bank interface). 
- Unloaded: The unloaded balance network simu- 
lates an 8OO-ohm transmission line which 
matches most CO trunks. 
NOTE: The present standard for trunks from the 
central office is 900 ohms. However, AT&T stu- 
dies indicate that an even better match can be ob- 
tained with 800 ohms for unloaded trunks and 
1650 ohms for loaded trunks. 
- 
Loaded: The loaded balance network simulates a 
165O-ohm transmission line which more closely 
matches the qualities of a central office trunk 
that has a loading coil included in the trunk be- 
cause the central office is very far from the in- 
stallation (usually over 18,OfKl feet). 
Trunks can be loop or ground start (unless they are 
on a Loop Start Card). 
Aground start trunk can be programmed to begin the 
call as soon as dial tone current is detected or to wait 
for the Dialing Wait timer to expire. 
Trunks can be set for MMF or dial pulse signals. 
(Dial pulse is not recommended for LSC trunks. The 
pulse circuitry on the LGC is more sophisticated and 
would provide better performance.) 
Each circuit on the EMC has two jumper straps, one 
for selecting the signaling type (1,2,4, or 5) and one 
for selecting the audio type (2-wire or 4+&e). The 
signaling and audio type for each circuit must also be 
programmed in the database.

13.5 TRUNKS: To begin programming an individual 
trunk, scroll through the list box until the desired trunk is 
highlighted. Then continue programming the necessary 
trunk features as described below. 
13.6 
GROUP NUMBER: To program the trunk 
group 
number to which this trunk is assigned, select the 
Group # text box, and type the desired number (l-102 
for standard systems, 142 for expanded systems). 
13.7 RECEIVE GAIN: To set the receive gain, enter 
the gain amount in the Receive Gain text box (non-T1 
trunks can be -9dB to +3dB; Tl 
range is -15dB to 
+15dB). 
13.8 TRANSMIT GAIN: To set the transmit gain, 
enter the gain amount in the Transmit Gain text box 
(non-T1 trunks can be -3dB to +6dB; Tl range is -15dB 
to +15dB). 
NOTE: Transmit and receive gain should not be 
changed unless the system is experiencing volume prob- 
lems. Before changing the values contact the telephone 
company to ensure that their trunks are in proper order. 
FCC regulations specifies 6dB gain for CO-to-CO con- 
nections. Increasing the gain above zero may place the 
system in violation of the FCC regulations. These ad- 
justments were intended for use with connections other 
than to telephone company trunks, such as a customer- 
provided OPXor ringdown circuits. Raising the gain too 
much could cause feedback during multi-party confer- 
ence calls. 
13.9 HYBRID BALANCE: (Nor 
available for TI 
trunks or 4-wire E&M trunks) 
Balance can be set to 
ideal, unloaded, or loaded by selecting the desired 
option button in the Hybrid Balance box. 
13.10 E&M INTERFACE: 
When programming an 
E&M trunk, designate the signalling type (1,2,4, or 5) 
and the audio type (2-wire or 4-wire) by selecting the ap 
propriate option buttons. This programming must match 
the jumper settings on the EMC. 
13.11 
START TYPE: Determine whether the trunk is 
a ground start trunk or a loop start trunk by selecting the 
Start Type box and then selecting the desired option but- 
ton. The selected option button will have a black dot in 
the center. This option is not available for BMC, LSC, or 
TlC circuits. 
13.12 CURRENT DT DETECT: (Ground 
Start 
T-u&s Only) 
To program the trunk to begin processing 
an outgoing call as soon as dial tone current is detected 
(bypassing the Dialing Wait timer), select the Current 
DT Detect check box (by pressing the SPACE BAR) to 
place an X in it. Selecting it again will remove the X.

B. TRUNK GROUPS, DID GROUPS, AND 
modes, or any combination of the following can be 
RlNGJN/ANSWER PAlTERNS (TRN?Q used. 
13.16 When you select Trunk Groups, DID Groups, 
and Ring-In/Answer Patterns from the Trunk Program- 
ming menu, or enter the TRNK command, the window 
appears as shown on page 5-108. - Single: If the trunk group will ring at a single sta- 
tion, determine the circuit or extension number 
of the station. 
13.17 ‘Dunk Groups: To prepare to program trunk 
groups, determine the following information. (Refer to 
the program planning sheet in Figure 5-25 on page 
5-236.): - 
Multiple: If the trunk group will ring in to more 
than one station, list those stations by circuit or 
extension number in a ring-in/answer pattern and 
assign the pattern to the trunk group. 
- Hunt 
Gmup: If the trunk group will ring in to a 
hunt group, determine the hunt group’s number. 
Trunk group description (up to 20 characters) and 
display identification (up to seven characters). 
The tenant group number of the attendant (other than 
the primary attendant) that can place the trunk group 
in night mode. 
The Hookflash feature can be enabled or disabled for 
each trunk group. If disabled, users cannot use the 
Hookflash feature code (330) while using the trunks 
in the trunk group. 
E&M trunks can be placed in trunk groups. E&M 
trunk groups may be designated as immediate start, 
wink start, or delay start in database programming. 
The call routing can be programmed to automatical- 
ly ring in (auto ring in) to the system’s attendant or to 
allow callers to dial extensions as desired (dial re- 
peating). If callers are allowed to dial extension 
numbers, the trunk group programming must indi- 
cate whether the 4161832 
System will send dial tone. 
Reorder tones on E&M trunk groups can be pro- 
grammed to be sent as continuous tones or a short 
burst of reorder tone; a short burst allows the user to 
try again, continuous tones prevent the user from 
further dialing. 
Determine if the trunk group contains all incoming- 
only trunks. Certain types of trunks, such as incom- 
ing WATS, need to be marked as “incoming-only” so 
that the system will recognize the trunks during 
power-up and/or testing. (This is because, on these 
types of trunks, ground signal is not returned on Tip 
and the system cannot power up the trunk unless this 
option is enabled.) 
Lists of stations with outgoing access for each trunk 
group. 
The music-on-hold channel (channel one or two, 
tick-tones, or silence) that will be used when callers 
on that trunk group are placed on hold. 
Ring-in type is determined separately for day and 
night modes. Ring in can be the same for both - DISA: If the trunk group is to be used for DISA 
and a security code is desired, determine the 
four-digit security codes (day and night) and de- 
termine if the security codes will be needed for 
intercom access. If using Etieded software, 
also determine the toll restrictions, for each 
DISA trunk group, that will be applied when an 
outgoing call is placed. 
NOTE: While DISA is designed to be reason- 
ably secure against misuse by outside callers, 
there is no implied warranty that it is invulner- 
able to unauthorized intrusions. The installer and 
owner of the system should ensure that proper se- 
curity measures have been taken to prevent out- 
side callers from accessing and misusing outgo- 
ing trunks for unauthorized calls. 
Determine if the trunk group is subject to toll restric- 
tion. If the trunk group is not subject to toll restric- 
tion, the station class of service (SCOS) is not 
checked when a trunk in the group is used. 
The trunk group can be exempt from, or subject to, 
the LCR only restriction. If exempt from LCR only, 
stations with SCOS 6 (LCR Only) using the proper 
access code can directly access the trunks. 
If subject 
to LCR only, stations with SCOS 6 can access the 
trunk only if it is part of an LCR facility group. 
For unrestricted trunk groups, determine the call 
cost rate to be used for calls placed on the trunks. 
Call cost can be: free, local rate, ten-digit rate, or op 
erator-assisted/international rate. 
Trunk groups that are subject to toll restriction can 
be designated as equal access trunks to allow 
10xXx and 101xXxX codes to be used when ac- 
cessing long distance carriers. 
Trunk groups can be programmed to absorb digits 
for PBX installations and installations in areas 
where the first digit(s) of the office code are 
absorbed. If absorbed digits are used, determine if 
they are repeatable (that is, they are absorbed if the 
absorbed digit string is dialed repeatedly).
