(TableNo.)# (AreaCode)# (Add/Remove)#
Input all area codes into a Time Priority Route Table. Maximum 1,000 area
codes (000-999) per Table. All area codes you want routed by LCR must be
input into a Time priority Route Table. If you need to set up special area/
office code combinations as “exceptions to the rule”, use 
Step 5 below.
Example:Assign area codes you want LCR-routed to Table 1 (long-
distance). If a dialed area code is not assigned to a Time Priority Route Table,
it will be routed to pooled trunk group “9”.
Step 4: Set Up LCR for Local DialingFF8 
2# (TableNo.)# (OfficeCode)# (Add/Remove)#
Every office code (exchange) to follow LCR must be input, one at a time, to a
Time Priority Route Table. Maximum 1,000 office codes (000-999) per
Table.
Example:Assign all office codes in the site’s local area to Table 2 (local). If
a local office code is not included in Table 2, it will be routed to trunk group
“9” when dialed.

Step 6: Set Up Add/Delete DigitsFF8 
7# (TrunkGroup)# (DeleteDigits)#
FF8 8# (TrunkGroup)# (AddDigits)#
The DBS will automatically outpulse Add Digits, or prevent Delete Digits
from being outpulsed, at the beginning of all phone numbers dialed on trunks
in the assigned group. The Add/Delete Digits are associated with LCR trunk
groups, not with the dialed phone number or the time of day.
Example:When the DBS is behind a PBX, assign “g-PAUSE” (press the
REDIAL key to insert the pause) so that the PBX will be automatically
accessed whenever a user dials out.
Activating LCR
lAlthough the FF8 addresses provide for LCR setup, you must activate
LCR in the “LCR Access” system address, FFl 2# l# 3# l#.
lYou can still build a Pooled Trunk Group “9” in FF2 (Trunk)# 3#, which
the DBS will access if 
all LCR trunks are busy.
lIndividual extensions can be forced to use LCR in FF3 (ExtPort)# 4#.
LCR Call Processing
LCR processes calls as follows:
1. An extension user dials an outgoing phone nurnber.
lIf 0,411,555,911, or 800 is dialed, the DBS will automatically drop
out of LCR and use pooled trunk group 
“9” (this trunk group is built in
FF2 
Trunk# 3#). This occurs to make sure these numbers are dialed
without any modification (e.g., 
LCR’s Add/Delete Digits Tables).
2. The DBS determines which Time Priority Route Table to use for the call,
based on the area code and/or 
office code dialed.
lIf the number is not assigned to a Table, LCR processing terminates
and the call is routed to pooled trunk group “9”.
3. The DBS will search all trunks in the Time Priority Route Table’s assigned
trunk groups, until an available trunk is found.
lIf all trunks in the first trunk group are busy, the DBS will search it
again. If all the trunks are still busy, the user will hear a “beep-beep”
tone as LCR proceeds to the next trunk group. Each trunk group is
searched twice.
lIf no trunks are available in any trunk group (whether LCR or not), the
user (after hearing busy tone) can dial 
“2” to have the DBS call back-
Page 8-4DBS Manual - Issued 8/l/95DBS-70-400 
						

							Section 400-ProgrammingChapter 8. Least Cost Routing (FF8)
when a trunk becomes available. When the DBS recalls, the user picks
up the handset and the DBS will automatically redial the number.
4. When a trunk is found, digits are added to or deleted from the phone
number, according to the Add or Delete digits assigned to the trunk group.
.
Using LCR With a PBX System
When the DBS is behind a PBX. two “9”s have to be dialed to access an
outside line --once to access the PBX, and again to access a trunk line. In
these cases, LCR is often used to add the “9”s automatically (via the Add
Digits Table) so the user doesn’t have to dial them each time.
Ln earlier CPC versions (CPC-A lower than 3.21; CPC-B lower than 2.1 l),
some office codes -- specifically, 941,955,991, and 980 .-- shotlld not be
routed through LCR in PBX systems. Because of the “9” dialing require-
.ment, and because the DBS automatically drops out of LCR if 0,411,555,
911 or 800 is dialed, the DBS may interpret these special numbers as office
codes instead.
For example, if “9-9 
11” is dialed to access a trunk and make an emergency
call, LCR may assume office code 991 was dialed instead. Therefore, 
do not
assign office codes 941,955,991 or 980 to Time Priori@ Route Tables if you
have an earlier CPC-A or CPC-B version.

Time Priority .Route Tables
Software Version: All Versions
Address: FF8 
5# (TableNo.)# (Position)# (TrunkGroup)#
DescriptionUse this address to assign LCR trunk groups to Time Priority Route Tables.
Within each Table, LCR trunk groups are assigned to priority positions in six
time-of-day periods (in the 
format shown in Table 8-2 below). This sets up
LCR routing paths for the DBS to follow when outgoing calls are placed.
Area codes and/or office codes are also associated with Time Priority Route
Tables, using other addresses. When a user dials the area code and/or 
office
code, the DBS will route the call to the trunk groups in the assigned Table
based on the time of day/weekend when the call is placed.
The first position in each time period is the highest-priority position for that
time period. For example, if a call is placed at 
8:35 pm, the trunk group
assigned to position 25 will be tried first when the call is placed (refer to
Table 8-2 below). If the DBS cannot access a trunk in this group, it will
search the trunk group assigned to the next-highest position (in the same
example, position 26).

LCR Trunk Groups
Software Version: AlI VersionsAddress: FF8 
6# (TrunkGrp)# (Position)# (Trunk)#
DescriptionUse this address to build LCR trunk groups, which are assigned to priority
positions in Time Priority Route Tables (see FF8 
5#).
Each LCR trunk group can contain up to 8 trunks. A maximum of 8 different
trunk groups can be created. Within each trunk group, the trunks are assigned
to positions from the highest priority (position 1) to the lowest (position 8).
When a call is routed to the trunk group, LCR will try the trunk in the first
position, then the second position, etc.
LCR trunk groups are also used for assigning Add or Delete digits as a prefix
to dialed numbers routed to the trunk group (see FF8 
7# and 8#).

NotesTrunk Assignment to LC’R Trunk Groups.A trunk cannot be assigned to
more than one position within the same LCR trunk group. However, the same
trunk can be assigned to several different groups.
Avoiding Glare.Glare occurs when both ends of a trunk are seized at the
same time, causing accidental connection between an incoming caller and a
DBS extension user preparing to make an outside call. Since incoming calls
will access DBS trunks starting from the lowest to the highest trunk number,
glare can be avoided by routing outgoing calls to the highest-numbered trunks
fast. So, when you build LCR trunk groups, assign trunks in descending
order (from highest to lowest trunk number) to trunk group positions in
ascending order (from lowest to highest position). For example, assign trunk
7 to position 1; trunk 6 to position 2, trunk 5 to position 3, etc.
